Dahlias like moist however well-drained soil. The tubers can take up numerous water, however they’ll rot if the soil stays moist. Throughout dry intervals, water your crops deeply at the very least twice per week. They want a minimal of 1 inch of water per week. Use a rain gauge or a small container to find out how a lot water your dahlias are getting.
Fertilizing Dahlias:
Dahlias work onerous to provide these large lush blooms and are thereby thought-about heavy feeders. There’s numerous blended details about the perfect system for fertilizing dahlias, so I’m simply going to share what I do. Once I pot up the tubers within the spring, I plant them in a potting combine that has fertilizer in it.
Once I plant them within the floor, I add a scoop of Osmocote, a slow-release fertilizer, and blend it into the soil. Relying on the bottom soil, I can even add a shovel of compost. Throughout the summer season, I put my dahlia mattress on the identical fertilizing schedule as my annual flowers and container plantings and fertilize each 2-3 weeks.
The Significance of Staking Dahlias in Your Backyard
After getting your dahlias planted, it’s necessary so as to add a stake instantly. Dahlias develop fairly tall so it’s essential to have a tall stake. I like these stakes. Because the plant grows, proceed to tie the stem to the stake.
If dahlias aren’t staked the tall stalks will fall over and break with the load of the heavy flower heads or robust winds. Typically occasions with out stakes the principle stem will develop crooked and be unable to face by itself. Don’t skip staking your crops.
I like utilizing tomato cages too to stake dahlias. Particularly these rising in pots.
Rising Dahlias in Containers
Sure, dahlias will be grown in containers. The truth is, I consider the best strategy to develop dahlias is in containers. Right here’s find out how to do it:
Choose a container that’s massive sufficient to maintain the expansion of the tubers and ensuing root system. I like to make use of containers which might be 14” or bigger with ample drainage holes.
The planting instructions are usually the identical as if you’re potting up tubers within the spring. Fill the container about 2/3rds of the way in which stuffed with high quality potting combine that accommodates fertilizer. Place the tuber in the course of the container, with the crown or the previous stem on prime and the tubers hanging down. If it’s one tuber, simply lay it on It’s facet with the attention pointing up. Then simply fill in across the tubers and canopy with about 2 inches of potting combine. Water properly. Let the soil dry earlier than watering once more.
As soon as the tubers or plant is planted, I put a tomato cage into the container to help the dahlia because it grows.
I normally fertilize my dahlias rising in pots each 2-3 weeks through the summer season.
How one can Overwinter Dahlia Tubers
In the event you’ve by no means tried to overwinter dahlia tubers, I need to encourage you to offer it a attempt. After getting it down and dealing properly within the surroundings the place you retailer them, the tubers get greater yearly and will be divided so you’ve gotten extra crops to share or promote.
There are various other ways to overwinter dahlia tubers, so I’ll share a few of these and share what has labored for me. This may be trial and error as a result of not everybody’s storage conditions are the identical. You’ll have to experiment to see what works for you.
On the finish of the rising season, you possibly can wait till frost zaps the dahlias, or dig them just a few days earlier than the primary fall frost in your space.
Step 1 – Utilizing loopers, lower down the dahlia plant leaving a couple of foot of stem. This makes it simple to deal with the clump of tubers. Go forward and make a bouquet of the remaining flowers.
Step 2 – Dig up the dahlia tubers. I extremely suggest utilizing a backyard fork for this chore. I discover that harm to the tubers is minimal once I use a backyard fork as a substitute of a shovel.
Step 3 – In case you have the time dahlia tubers will be rinsed off and cleaned. In any other case, clear off any extra soil together with your fingers and permit the tubers to dry. Don’t retailer damp tubers as a result of they’ll possible rot or develop mildew.
Storing Dahlia Tubers
That is the place success or failure comes into play. There are a number of methods to do that and you’ll have to experiment and see which approach works finest in your state of affairs.
- Retailer the tubers in peat moss or vermiculite in a plastic bin.
- Lay out the Dahlia tubers in a crate.
- Retailer the tubers in peat moss or vermiculite in a plastic ziploc-type bag.
- Merely retailer the tubers in a plastic grocery bag and loosely tie the highest. That is how I retailer my dahlia tubers.
Regardless of which methodology you determine to make use of to retailer your dahlia tubers, they have to be saved in a cool, darkish place. The best temperature for dahlia tuber storage is between 40 – 50 levels Fahrenheit.
Not solely do temperatures of the room must be excellent, humidity ranges are necessary too. If the storage space is simply too humid, the tubers will develop mildew and decay. If the storage space is simply too dry, the tubers will shrivel and dry up.
Many dahlia growers say that they test on their saved tubers each few weeks all through winter and spritz them if they’re too dry. I simply must be sincere right here and say that is simply not sensible recommendation for me or most residence gardeners. In case you have the time and care that a lot about your dahlia tubers, then by all means test on them through the winter.

Dividing Dahlia Clumps
As dahlia tubers develop 12 months after 12 months the clumps can develop into fairly massive. To maintain them wholesome, it’s necessary to divide the clumps. I was a little bit bit intimidated to do that, however it’s actually tough to destroy a clump of dahlia tubers and simple to divide them with a sharp knife and backyard shears.

When planting your dahlia tubers or crops depart ample house between the crops for good air circulation.
Are dahlias lower flower? Sure and no. In the event you develop dahlias in your personal satisfaction, then sure they’re pretty lower flowers and I develop them in my lower flower backyard.

You may lengthen their vase life a little bit bit by utilizing lower flower meals, however solely by just a few days.
