We began growing them as soon as we figured out how. In California, Dahlias can stay out all year long. New England residents need to dig up the tubers from the ground and store them in a cool dry place during the winter.
Cold-weather gardeners can just plant in pots indoors in the spring. Dahlias are easy to care for. They don’t need a lot of water, but they do need regular fertilizing to keep them looking good.

How do you grow dahlias in pots indoors?
If started outside, put the containers under plant lights.. The light from above should help the dahlias grow compactly and keep them from bending towards the light of a window. The lights should be set six inches from the tops of the pots. Plants begin to flower when the lights are raised.
When the flowers are in full bloom, remove the bulbs and place them in a cool, dark place for a couple of weeks to allow them to dry out. When they are ready to be transplanted, cut off the stems and plant the new bulbs in the same location.
Can you grow dahlias in pots?
It is possible to grow dahlias in a pot, even if you start them in undercover pots in the garden. Some dahlias can grow to be quite large, so make sure you choose a small one. The best way to start a Dahlia plant is to cut off the top of the plant and place it on a flat surface, such as a piece of cardboard or a coffee table.
This will help to keep the soil moist and prevent it from drying out too much. The soil should be moist but not soggy, and it should not be too dry either. You can also use a garden trowel to help with this, but be careful not to over-drain the pot as this can cause the roots to rot.
Once you have placed your plant in its pot, you will need to water it regularly to ensure that it gets the nutrients it needs. If you are using a soil-less soil mix, then you can water your Dahlias at the same time that you water the rest of your garden.
Can dahlias be overwintered in pots?
Yes, you can overwinter dahlias in pots, and it is very easy. Once frost has killed the plant, simply cut it back, bring the container inside, and store it in a dry place.
Will dahlias bloom indoors?
You can start dahlias indoors in order to be able to transplant them and start growing them outdoors as early as possible. You can grow them indoors in a greenhouse if you keep them in containers.
How do you start dahlia tubers indoors?
If you want to start the bloom earlier, start the tubers indoors in early April. If you fill an 8-inch pot with a commercial mix, place a tuber horizontally on the mix surface, then cover it with an additional 1 or 2 inches of soil. Don’t forget to water thoroughly. Spring is a good time for planting, as it is when the weather is warm and the soil is moist.
In the fall, however, you may want to wait until after the last frost before planting. If you wait too long, your tuber may not germinate properly and you will have to start again from the beginning. You can also plant the tuber in late spring or early summer, depending on where you live and how long it has been since you last watered it.
For example, if it was planted in April, it may need to be watered again in May or June, or you can plant it in September or October. The same is true if you planted it last year in March, but this year it will need a little more time to germination.
Should you start dahlia bulbs indoors?
Dahlias planted indoors the first week of April will be well started by mid-May. Many growers find that a garage or basement works just as well as a greenhouse. The pots should be placed under the fluorescent lights six inches above the plants. The Dahlias grow best in a well-drained soil with a pH of between 6.5 and 7.0.
The soil should be moist but not soggy. If the soil is too dry, the plant will not be able to take up enough water to keep the roots moist and healthy. Too much moisture can also lead to root rot, which can be fatal if left untreated.
When should I start my dahlia seeds indoors?
Start your seeds indoors 6-8 weeks prior to your last frost date. This will give you enough time to grow your dahlia flower seeds so that they can flower in the summer. If you are planting indoors, make sure that the soil is well-drained and that there are no weeds growing in your garden.
How long does it take for dahlia tubers to sprout indoors?
It can take 4 or 5 weeks for a dahlia tuber to sprout so if they are pre-sprouted, they are ready to start growing when you plant them. I try to plant my dahlias in the last week of April in North Carolina. If your plant is still green, then it is ready for harvest.
If it has started to turn yellow, it will need to be removed from the soil and allowed to dry out for several days before it can be harvested. It is best to harvest the plant when the leaves have turned a light shade of yellow and the flowers are beginning to open. You can also harvest them when they have opened, but they will not be ready until the next growing season.
