Dahlias Delight
I don’t think many people need a reason to grow dahlias, and for those of us that love them in colder zones like New York where they don’t overwinter it’s a labor of love to grow, store, and plant them year after year.
For a glorious few months in the late summer and early fall they pour out blooms as fast as you can cut them, but for much of the year they are dry tubers stored in a basement or just green foliage emerging from the soil.
A few of my favorite varieties
- Hollyhill bewitched & black beauty – a deep purple red almost black, and white/deep almost black
- Creme de Cassis – a beautiful creamy ivory face with deep purple edges/backs of petals
- Bacardi – magenta and deep purple
- Penhill Watermelon & Dark Monarch – dinnerplates with twisted petals in salmon pink/peach and complex pink/purple gradient
- Big Brother – dinnerplate with twisted petals in honey/orange tones
- Chewy & Crichton Honey – two ball varieties with pink/peachy colors, the blooms change with different temps
- Snowbound – beautiful large white blooms
- Platinum Blonde – white single ring of petals surrounding a creamy white pom center
Planting & Storing in Colder Zones
A note on ordering tubers – with almost every supplier and every order I have gotten incorrect colors/blooms not matching what I ordered. It’s so hard to get some of these varieties, so proper storage is the safest way to get them in your garden from year to year. I have been so sad when a variety I loved didn’t survive storage because they often are sold out before spring and then it’s at least two years before you even have a chance to see that flower again. So feel free to practice and perfect growing and storing them for a year or two before you invest in expensive varieties.
Planting in the spring
- Remove and inspect tubers for damage – do not plant any that have rotted, tubers should feel like a potato dry but firm not squishy
- Planting is relatively straightforward, but for the first time grower they often arrive as individual tubers or clusters
- After all chance of frost has passed, plant them just below the surface (if there is a stem facing up) but if just a single tuber lay it on its side and their sprouts will grow towards the light. If it’s later in the season you may see an eye or stem emerging. If you have stored them or want to make sure they are viable you can wait until this emerges to plant knowing it may delay bloom time (which is tragically short in some regions)
- Slugs are the main pest as new green growth emerges I sprinkle slug bait to prevent them
- After slugs overwatering is the main concern, and later flowers are vulnerable to thrips and others pests depending on your area. Some gardeners bag the blooms to prevent damage but I find the pest pressure has always equalized by that time for me.
- They benefit from cooler temps and water only once their green growth and feeder roots have established.
Process to dig and store dahlias at the end of the season
- After a frost has killed the blooms and foliage you can cut back the stems and carefully dig up your dahlia clumps. I use a hori but some people use a garden fork.
- After you have lifted them out of the soil, rinse, inspect and trim broken or damaged sections
- If you choose to divide them now give them time to dry and heal
- Organize and label – this part is so important if you want to group like colors or heights. I use cut up sections of yogurt containers with sharpie to add labels in bins and transfer to the soil. If i need to rewrite them I use alcohol to wipe off sharpie
- Add storage material like wood chip bedding or peat moss and store in a cool/dark place like an unheated basement. It must not go below freezing or tubers will not survive
From Garden to Vase
I tend to display my dahlias individually in vintage glass bottles or vintage milk glass bud vases. I sometimes add them into arrangements but find they have a much shorter vase life than other blooms and prefer to be able to change them out quickly.
