Just say no…to slugs – The Dahlia Dish May 22, 2023

If you have a lot of slugs, you’ll have a lot more slugs if you don’t do anything about it!

It was happy hour and I put in a pretty good day! I enjoyed a cold beer in the sunshine and got to thinking… I don’t want to jinx myself by saying this out loud but “I haven’t seen a single slug in the last few weeks”. Earlier this spring I lifted a board in the garden and found a big old kinda dead looking slug along side a cluster of slug eggs – I found two clusters which I quickly ended! Since then, nothing…it might be a wee bit early to start seeing them on the regular. I’m just in the midst of serving up the biggest smorgasbord of the year – new dahlia greens… so I’m very interested to see how things progress in terms of slug pressure this year.

Last year we endured inconceivable slug pressure early in the season when the dahlias are just trying to get their feet under them and I’m pretty sure it was my fault. I spent hours and hours hand picking slugs off the precious dahlias… mostly tiny skin coloured baby slugs smaller than the size of a dime…some smaller, some bigger. For about 4 weeks, I was out in the patch every morning and night for a total of about 4 hours per day hunting slugs.

What to look for: If you find leaves with holes in them or chewed edges, you’ll likely find slugs as the culprit early in the season (May/June). When the plants are small with only a few sets of leaves, they are most vulnerable. Once the dahlias get ahead of the slugs, slug damage is less of a problem. Heavy slug damage can make a dahlia plant look stunted, with curled leaves that have been damaged by the slimy little pests.

When to find slugs on your plants: very early morning and late evening or the middle of the night with a headlamp!

The tiny slugs seem to cause the most damage because they are harder to spot and when you think you’ve got them all, you probably have not! They hide under the leaves, and even tuck themselves into spaces where the stalk of the dahlia emerges from the soil. I had thousands of these slugs… it wasn’t uncommon to find 10 of these little buggers on one plant in one morning and find 10 more the next morning! Where were they coming from and what did I need to do differently?!!!

I realized I had some bad habits that needed to change: piles of pulled weeds in every row left for extended periods, pots full of pulled weeds left for extended periods, and possibly “strategic” tarps left down over the winter.

For the past year, I have been dedicated and disciplined about not leaving piles of pulled weeds in the beds or on my pathways – no more leaving pots full of decomposing weeds in the garden and I didn’t leave any tarps down over the winter. I went thru all the effort to do the weeding, but because I didn’t “finish the job” by immediately moving that stuff to the compost, I created more work for myself that would turn out to be extremely time consuming – dealing with slugs and lots of them! They love things like big pots and wood and piles of decomposing plant matter to hide under for shelter during the day. All are intimate hideaway havens for slugs to meet up and make egg clusters – how many eggs in a cluster? LOTS!

So far… it seems that easy… remove all those things that make inviting slug habitat and you will have way less slug activity in your patch! I’m expecting that a few slugs will show up for the party soon, but I’m hopeful there won’t be the thousands and thousands experienced last season. Fingers crossed! I’m ready for them with my bucket of salt water and good clean garden habits! …

When do you plant your dahlias outside? … or maybe the more common question is – how early can I plant my dahlias?! A good question! The answer(s) depend mostly on where you live and when you expect your last frost. An easy rule of thumb to remember is to plant your dahlia tubers when the lilacs start blooming.

Dahlia NOID Red Velvet

If your tubers are in cold storage, take them out to warm up and eye up just a couple weeks before your frost free date. This is not absolutely necessary, but if you have any “blind tubers” in your bins, then it’ll save you planting any duds.

Dahlia Blue Boy

If you are eager to get your beauties started earlier than your frost free date (perhaps you live in a really cold climate with a short growing season), you’ll need grow lights, grow room with lots of space, and a heated greenhouse would be excellent. If you have all these resources, then you can get started almost anytime. It is a fair bit of work, but its not work if you love it right?!

Dahlia Boom Boom White

What if I plant my dahlia tubers out in the garden before my frost free date? If you’re a risk taker or maybe you like to push the boundaries or maybe there is another reason that you’d want to plant your dahlia tubers outside before your last frost free date (maybe you’ll be away during that peak planting period which is mid-May for us in Terrace). I have planted my dahlia tubers out in the garden in mid-April in Terrace, once because I was going to be away from the end of April until the first week of June – I came home to lovely dahlia plants happily growing. Another time I had all my dahlias started early and they had lovely green shoots with beautiful sets of leaves. I hardened them off outside for a few days and then planted them out – the very next morning we had our last frost of the year and as soon as the frost melted all my beautiful dahlia plants wilted from the nip of frost. Had I covered them with frost cloth, they may have been protected enough and carried on without any damage.

Dahlia Star’s Lady

If you must plant your dahlias outside in the garden before your frost free date, here are a few things to consider.

  • If the frost nips your dahlias new growth, all is not lost. If the tuber is in good shape it will push up new shoots. The frost kill will likely set back your dahlia’s growth by a couple weeks.
  • If you plant dahlia tubers out early, know that they won’t do much growing until it warms up. Its kind of like putting them in cold storage out in the field – but where they are potentially subjected to additional abject conditions like risk of bugs/pests, rainy weather (a lot of rain and poor drainage can lead to rotting of tubers), frosts (kills off new growth and sets back new growth by a few weeks if your tuber doesn’t rot)
Dahlia Just Peachy

So what do we do at Medeek Meadows? We wait for the lilacs to bloom – mostly! We get our dahlias eyed up ahead of time by moving them out of cold storage as much as a month before our frost free date. Some varieties take longer than others to eye up. We check the weather, and look for signs of frost in the forecast – those mornings after a brilliant sunny day with clear skies at night are the ones to watch out for. Most of our dahlias are field grown. On our mission to get earlier blooms, we look for varieties that are earlier bloomers rather than getting them started early. Dahlias typically bloom from late June until frost. At Medeek Meadows Dahlia Farm in Terrace BC, we don’t expect or rely on June blooms. We usually start seeing dahlia blooms in our bouquets by mid-July. This is always weather dependent – and if we get a cool, wet summer our hopes for July blooms diminish… Dahlias are usually “full-on” in August and September. Dahlias like summers to be the same way we do – moderate warm temperatures, not too hot and not too cold with lots of sunshine.

A name to remember… Berner Oberland, Zundert Mystery Fox, Boom Boom White… often creative, often familiar, and sometimes not so much!

Dahlia Berner Oberland

Berner Oberland – a beautiful and rather uncommon waterlily variety. The name? Could it be named after a person or a region in Switzerland? I wish I knew!

Zundert Mystery Fox – a lovely ball shaped formal decorative in the most delicious orange tone colour – a little bit coral – a little bit terracotta – a little bit watermelon. The name? Creative?! I’d guess that “Zundert” would be the breeder, and “Mystery Fox” perhaps a creative name…maybe a mystery seedling whose seed parents are unknown? Regardless… a beauty loved in bouquets.

Dahlia Zundert Mystery Fox
Dahlia Boom Boom White

Boom Boom White – a staple white dahlia for the garden or bouquets with it sturdy plant habit and great stems. The name? “Boom Boom” is catchy hey! I’m guessing that “Boom Boom” refers to a series of dahlias produced perhaps by a seed parent(s) and “White” simply distinguishes the colour of bloom in the series (you may also come across Red and Yellow Boom Boom dahlias).

Spring is in the air today in our neck of the woods! The sun is shining, the Canadian Geese are back honking away as they venture farther North… A beautiful day to get some things done outside when we take a break from transplanting dahlia seedlings & petunias … and prepping dahlia tubers for packaging. A favourite time of year to be sure.

Confusion in the garden!!! … You’ve carefully labelled all your dahlias, tended them religiously, and endured the long wait and anticipation to see them bloom. As they grow, you admire their foliage and even may be thinking you know which dahlia you’re looking at without checking the label because its foliage is unique… but then the first bloom appears and its not what you were expecting! The label doesn’t match the bloom! It’s pink not red! It’s short not tall! Its a ball not a cactus! What happened?

Many things can lead to mixing up dahlia varieties. There is not just one single way that it happens, and mix ups happen to just about every grower of dahlias from time to time. Sometimes the mix ups result in happy accidents and sometimes they are disappointing – but all just part of the fun – keep calm and keep growing beautiful dahlias!

  1. Imported dahlias purchased from big box stores, garden centres. The vendor hasn’t grown the dahlia themselves, and so is at the mercy of their supplier to put the correct tubers in the correct packages that you buy and grow. You buy “Thomas Edison” and when it blooms it turns out to be purple but in a ball form…or pink… or white…or….everything but TE!
  2. Smaller domestic farm grower/resellers. Repackaging and reselling “bulk” imported tubers has become more common amongst some smaller Canadian growers in the last 5-10 years. There is opportunity for a large profit margin. These growers supplement their own farm grown dahlia supply by repackaging and reselling tubers bought in bulk or wholesale and often imported from overseas growers. (This is sort of like buying a bag of 5 dahlia tubers like what you’d get from Canadian Tire or Costco and then breaking the bag apart and selling the tubers individually for a premium). This practice created a bit of a stir in the dahlia community when customers led to believe that they were buying “farm grown” realized that the tubers bought thru online shops were not in fact farm grown. Customers now expect domestic dahlia growers to explicitly state on their websites if tubers on offer are farm grown vs imported/repackaged/resold. The same “mix up” problem presents itself as in “1” above where the vendor is at the mercy of the supplier to ensure the correct variety ends up in the hands of their customer.
  3. Cuttings! Growing dahlias from cuttings is a recent trend. There is lots of opportunity for mix-ups here too! Maybe you landed a single “unicorn” tuber and you’re so excited that you take 10 cuttings from this beauty with the hopes of having a garden full of unicorns…only to find out that you end up with 10 “meh” plants that don’t look anything like your unicorn. If you take cuttings from a dahlia tuber that you have not grown, there is a risk that you’ll multiply a mix-up.
  4. Labelling (or lack there of)! So many different methods of labelling and when to label. Labels on tubers, labels on and in storage boxes, labels on stems, labels on trays… Can there ever be enough labelling? Develop a good labelling system that works for you and refine it as needed…
  5. Human error! We’re all human – so be gentle with yourself and others when a mixup happens!
  6. ….other ways… I’m sure there’s more…like bad habits! If you’re not sure what a variety is, mark it as such… don’t mix it in with the variety you “think” it might be.

How can you keep your varieties straight?

  1. Make a habit of using a good labelling system. Label tubers. We label with our inventory number and the variety name… and if its a “new to us” tuber we also label it with the source.
  2. Map out your dahlia beds, so you know which varieties are growing where and which are next to which.
  3. During the growing season, when the dahlias are in full bloom is THE BEST time to discover and fix errors by reviewing your blooms to ensure they are what you expected. “Flag” anything that needs a labelling adjustment. Surveyors flagging tape is a great way to tie a label to the stalk with a note to remind you when it comes time to dig and the blooms are long gone. Just make sure you attach the flagging tape to the correct stalk!!! Using permanent markers like sharpies is OK, but know that these have a habit of fading over time outdoors. Using nursery paint or permanent indelible ink markers are a better choice because they resist fading.
  4. When you dig/lift the tubers in the fall, dig and process one variety at a time.
  5. Label storage boxes on the outside and the inside.
  6. If we end up with a tuber that we’re not sure about, it goes into a “mystery” bin (we might add a label to it with a “?” and the variety we think it might be)

You certainly don’t have to label your dahlias! But it really does help to know which is which when you’re planting a lot of them. Knowing the tall or vigorous from the shorter or less robust will help you when you’re planning which dahlia to plant where in your garden.

Dahlia 040 NOID Rocco mislabled from
Dahlia 040 NOID

NOID? What the heck is a Dahlia NOID? … In short, a NOID is a Dahlia who is well loved, grown and nurtured from year to year, but whose name has been lost, forgotten or never known. A NOID is never a Dahlia destined for the compost heap – NOID is a term only used for dahlias that we love and keep. NOID is simply a short reference to “NO IDentification”.

We give our NOIDs a number and a short description that helps us remember which bloom we’re working with during different times of the year when there are no blooms to see (like this time of year when we’re checking our tuber inventories in winter storage). The Dahlia pictured above is known to us only as “040 MM NOID Rocco mislabeled from source”. We’ve hung on to her because we love her qualities.

040 MM NOID is a beautiful dahlia that we see a lot of value in keeping. We acquired her by mistake when we ordered a dahlia named “Rocco” from a grower who sent us a tuber that was not actually “Rocco” but something else entirely… a happy accident 🙂 She’s in the category of very dark red, almost black dahlias – a very nice colour that works with blush pink bouquets – the light in the photo above shows the red in her bloom, but in real life, the bloom looks much darker (see photo below). Beautiful dark stems – an excellent cut flower for bouquets. A good bloomer and often an earlier bloomer for us.

Dahlia NOID (not Rocco)

We use these colour cards from the American Dahlia Society to help us narrow down the colour of Dahlia blooms… its super handy and also very interesting to see the blooms next to the cards. Sometimes its hard to get a good match because the colour variations are almost limitless!

“Dahlia 035 MM NOID – Boppa’s Tutie Fruity” is another favourite NOID. Definitely of sentimental value because it’s an oldie from the farm – my Nana and Boppa’s old Dogwood farm on Vancouver Island. But we love it because its got that gorgeous “flare” of yellow and red. Its a stunner in the garden and also is blessed with great stems for bouquets.

Dahlia Fire Magic

“Fire Magic” originally came to us as a gift from my sister Jacklin. But! She was given the name “Coral Nancy” because they didn’t know the real name and so she became known as “Coral” for her bloom’s beautiful coral colouring + “Nancy” for the woman who gave a friend a tuber awhile back… So for a few years we called this one “Dahlia 009 NOID Coral Nancy” until one summer we accidently stumbled across her real name! We ordered a dahlia called “Fire Magic” which turned out to be exactly the same bloom & tuber production as ol’ Coral Nancy… a little confusion in the garden…and then voila! That’s how we solved the mystery of “009 NOID” (an accurate and consistent naming and labelling system helped too!).

We try to solve all the mysteries! But sometimes it takes years. A search on the internet sometimes turns up an exact match but not always. There are thousands and thousands and thousands of dahlias and some are never named (like those for sale in mixed bags of tubers from big box stores and garden nurseries with packaging names like “Ball mix” or “Cactus mix” or “Waterlily mix” or “Decorative mix” or “Dinnerplate mix” or “Cut flower mix” etc. which are usually imported from large growers overseas). In order to make a match, you need to compare the bloom colour, form, and size. You also need to compare the plant’s growth habit and the size, shape, colour and style of tuber production. All these qualities can differ and provide clues to discover the real name of the well loved NOIDs.

More of our beautiful NOIDs!
If you think you know the real name – we’d LOVE to hear from you!

  • Dahlia 016 MM NOID Meg’s fav orange (possibly Glorie Van Noordwijk)
  • Dahlia 021 MM NOID Red Velvet
  • Dahlia 109 MM NOID Red/Yellow Cactus
  • Dahlia 139 MM NOID Dark Maroon Ball
  • Dahlia 142 MM NOID JJ’s fav purple (gorgeous bright pinky magenta bloom on dramatic dark leaved plant) *Update 2024 we discovered the name is Engelhardt’s Matador*
  • Dahlia 012 MM NOID JJ Bright Scarlet Red
  • Dahlia 113 MM NOID White Waterlily

Preserving Dahlias… So sooooo many of us long to see the beautiful dahlia blooms all year long! Dahlias (in Terrace, BC, Canada) can bloom from June + or – until first frost, but bloom time is highly variable and dependent on the variety and your growing location, growing conditions and weather. The earliest I’ve had blooms from any of my dahlias in Terrace has been mid-June. More blooms start coming on in July and they are in their full glory in the months of August and September. Come fall, when the temperatures start to dip, we start watching the weather forecast with keen eyes for any indication of frost that will put a quick end to the dahlias for the season…

So how do we preserve dahlias so that they can be enjoyed all year? They are not an “everlasting” flower like strawflowers and statice which hold their colour and shape really well when dried. Dahlia blooms tend to fade to brown and wither away into a crumpled unappealing fragile ugly mess. But that doesn’t stop folks from trying to dry them! I’m not one of them! But, some folks claim to have success drying them with silica… Its just not my jam, but if its yours, give it a go and let us know how it turns out!

My jam is preserving the beauty of dahlias through photography. During dahlia season, I spend hundreds of hours out in the patch with the camera (and iphone – remarkably powerful) snapping photos of our dahlias and then more time downloading them. Then in the off-season I spend a whole bunch more time gazing at all my beauties, choosing photos that I’ll use for the online dahlia tuber shop, editing them, documenting them, and uploading them to the website in preparation for the dahlia tuber sales over the winter. Most recently I commissioned a very talented artist Emily Gagnon of Three Cedars Studio (FB) to paint the dahlia “Good Day” pictured above and I’m just thrilled with her work! I provided Emily with a photo that I captured of “Good Day” for inspiration. Painted on a 12″ x12″ wood board – Emily used a piece of locally milled Yellow Cedar that was an off-cut/scrap piece from The Barn renovations @ Hidden Acres Farm and Treehouse Resort …We’ll be enjoying the beauty of this dahlia all year round for years to come! Thanks so much Emily!

Glorious Dahlia Tubers … a tuber is a tuber is a tuber as long as it has a viable eye from which a new plant will grow. If a tuber does not have a viable eye, it’s known as a blind tuber, and although it may grow roots, it will never produce a new plant. Tubers can be tiny (like the size of your thumb or even smaller) or huge (like the size of your forearm). They can be skinny or fat. They can be long or short. They can have some colour pigmentation or not! They can have thin necks or no necks. They can be “ugly” or “beautiful” and still both produce the same gorgeous blooms that are true to the parent dahlia that produced the tubers. They are even edible! Perhaps a good way to use up blind tubers in a nice “zucchini” style loaf made with peeled and grated dahlia tubers?

Growing dahlias from tubers is the most common and arguably the easiest way to grow dahlias. You may find them available as single tubers, or small clumps (pot tubers – commonly found with imported products in nurseries), or even as large clumps (less commonly found for sale, but often friends or family might offer them this way!). A tuber will carry the same genetics as its parent dahlia – unlike seeds from the same plant, where the genetic variation is so high that a plant grown from seed will usually look substantially different than its parents.

Dahlia tubers are extremely sensitive to freezing and the plants are not hardy – they can’t tolerate a frost. So in Canada, tubers are harvested in the fall, stored over the winter in cool & dark conditions, and then planted again in the spring when the risk of frost has passed (usually mid-May in Terrace, BC, Canada). Some folks in the milder climes of Canada have success overwintering dahlias in the grounds – but there is always the risk of losing them to a freeze.

Dahlia seedlings – what are they exactly? They are magical. They are exciting. They have both the capacity to surprise and disappoint. They are fun. They are so much more than just a plant started from a tiny seed!

What are they NOT? Dahlia seedlings will not grow true to their parents! They may have similar traits, but rarely look the same as the seed or pollen parent. Seedlings can vary from the seed and pollen parents in colour, form, height, tuber production, seed production, pollen production, foliage colour…

The 2022 growing season saw us grow approximately 500 dahlia plants from seed. Of those 500, we kept less than 80 to overwinter in storage and possibly grow out again in 2023. I spent a ton of my summer time in the seedling patch admiring, observing, recording and documenting the new blooms. And all the while I enjoyed the sweetly intoxicating scent of sweet peas wafting across from their trellis (planting sweet peas next to the dahlia seedling patch was an excellent idea!).

Skeena Darling was the first dahlia seedling that we kept back in 2020 (from 2019 seed)! Her own seeds have produced some stunners including the 2022-065 dahlia pictured above.

This was the beginning…where dahlia infatuation and straight up delirium started – thank you Boppa (RIP)! This is my one and only photo of some of the dahlias he grew (taken by a real film loaded camera – way before digital cameras and smart phone cameras were a thing)! It would have been taken in the summer 1995 + or – a few years.

By the look of the brown grass in the field behind the dahlias, it must’ve been a hot dry summer at “Dogwood” farm just outside Victoria on Vancouver Island, BC. The dahlias look like they’re “busting out”, well watered with a healthy dose of “black gold” well-rotted & aged sheep manure applied (ohhhh I’d love to have a big pile of that now!)

I remember once in a while snipping a big bloom to put in a vase in the house for him – but in hindsight I think he actually preferred them to stay in the garden! Good memories of deadheading spent blooms and helping Boppa lift the dahlias in the fall to store them away in the basement. He had great success storing them in whole clumps, in cardboard boxes in an unheated basement. Find more info about digging and storing dahlia tubers on our Dahlia Tips & Care page.
