Thank you, Trina. Ultimately, this is likely to be disappointing. Dahlias need space and lilac roots reach out about one and a half times the length of the branches—a foot-wide plant can have foot roots. So the dahlias would be choked out. Look around; you seldom see more than grass under lilacs, and this is why.
Is it too late to plant my dahlias? I live in zone 7b and I was just planning on planting them and not digging them up in the fall? Will they bloom? Can I plant the tubers now June 23rd? I didn't get a chance to put them in the ground earlier. Or should I wait until next year? I live in Zone 5b. I have it planted in a south facing garden without alot of shelter from the wind.
The foliage has turned a very dark green almost black and the although it has lots of buds the flowers hardly open then just end up dying. It was doing great for the first week, then this started. Sadly the same thing happend last year. Hi, Shannon. This sounds like fusarium wilt, especially since you say the same thing happened last year. Unfortunately you will need to destroy the infected plants and grow new plants in a different area. I live in Arizona, zone 9.
I have problem to grow beautiful dalias. It is degree F now. I planted in February, got one in each and some didn't. All are in a separate pot. Please advise. Plants in pots tend to be hotter and dry out faster than those in ground, especially in clay pots.
See the comments below about growing in pots, too. I have one plant blooming now and want to know if I leave it to winter in ground will it multiple like my Iris's do? Your dahlia should produce tubers from the original one, but to benefit from these new ones, you need to lift dig up the whole cluster, then separate them. If your plant has never been lifted, you might want to do this now, separate any new ones, and plant those with eyes.
Yes, dahlias can be grown in containers. Follow the same spacing and depth requirements mentioned above. Cover the tuber with a few inches of soil and water it in. If the tubers aren't planted after a season grown and dug up in the fall but not able to plant the following season and try to plant them the next season or do they get to dry and won't grow.
I would like to know if I can plant them in a pot and which kind of dahlia is best to do it thanks. Thanks for the helpful tips and information. I have a question, I bought Dahlia tubbers over a year ago and forgot to plant them, is it possible that they would still grow if I planted them now? Thank YOU , Michelle! About your dahlias: We here are eternal optimists, so…Check out your tubers.
If they are not dried out to a crisp, plant them, following the guidance above, and see what happens. I live in zone 6a. I would like to create a dense collection of dahlias to grow next to my fence - more of a bush type of look rather than individual stems. Any suggestions? Try planting a few different varieties with differing heights, staggering them in such a way that they still have room for themselves, but give the appearance of a dense hedge of dahlias. Ive bought a dahlia in a pot.
Its probably to late to plant it in the garden. So can i just leave it in the pot and store it in my none heated greenhouse over winter and plant it in the spring.
If you live in USDA Zone 8 or higher, you can leave the dahlia in the pot or in the ground over the winter. We hope this helps! Hi The Editors, I live in zone 10, my Dahlias were planted in the large container. The blooming season is ending soon and I will cut the plants down to the base. Please teach me: - Can I keep the tuber in the container until next year? But sometimes they burn when weather is 80 and above. For home gardeners, most of our remaining options are defensive.
Do everything possible to keep the foliage dry. Always water at the root zone. Allow lots of space between plants to encourage good air circulation. Once the plants are relatively mature, you can prune off some of the foliage at the bottom of the plant. Deadhead every couple days and remove any damaged branches or leaves.
Alway keep the area around the plants as clean of organic debris as possible. Hope this helps! Can we keep dahlia plant the same pot for off season.
I mean it is necessary to remove tuber and store it for next season. What if i keep the plant as it is for next season. As it is already mid March and i guess we can grow tuber in late June. So it is just 3. Do i really need to remove tuber and dry and store? Please answer. Hi — sorry for the delay in responding. You can store the tubers right in the pot. The two biggest risks for overwintering dahlia tubers is freezing and too much moisture.
Hope you have good results. It sometimes takes a couple tries to figure out the best way to overwinter tubers. So much depends on your climate and storage conditions. They seem to have a small flower heads. Will the heads get bigger next year or did I buy a small flower variety? Hi — Sometimes the first few flowers can be a little bit smaller than normal. With dahlias, flower size is particular to the variety.
This does not change from one year to the next. Check which variety you purchased and that should tell you what size flowers to expect. Hi there I live in Vancouver Canada. This is my first time growing Dalias… now that my tubers, that I have started in pots before I transfer into the garden, have started to show shoots, do I begin to water and place the pots outside in the sun?
I was going to wait till they were 6 inches high before transferring them to the garden Thank you. Hi Connie — yes! Do you recommend? Will those be viable or do they need to come directly from the tuber? Hi Hazel — dahlia sprouts emerge from the stem tissue, not from the tubers themselves.
So what you are seeing is normal. I learn something each year about how to keep them beautiful. Your articles were a great source of information. Hi there! I plan on putting them in pots. Also, do you recommend dedicating the pot solely to the dahlias or mixing in other fillers, etc?
Thank you so much! Hi Kristen — In this article at the bottom there is a chart with recommended minimum pot sizes for various summer-blooming bulbs: How to Grow Summer Bulbs in Containers. With all other types, we recommend just one clump per pot. If you want something to look at while the plants are getting established, you could plant some cool climate annuals pansies or sweet alyssum and then remove them as the dahlias start to fill in. My dahlia tubers have a couple inch long white sprout not green.
Do I put the white sprout under OR above ground? If the sprout is exposed, you may want to shield the top of the pot from direct sunlight for a couple days to let the sprout adjust to more light.
Maybe that last question applies here — my tuber was already sprouted when I planted it, but we had a hot day and it seems the top burned. Do you think the tubers will send up more shoots, or will those sprouts rejuvenate? Hi Rebecca — I think you should just give it a couple weeks. Dahlias have a lot of growing power and I bet that plant will come back with more shoots. Hope so! I wanted them nightly at the same time and I fertilized them about two weeks ago…..
I live in Central Florida. Hi — With dahlias, too much moisture, especially when the plants are still young, can inhibit growth. So you may be overwatering them. But you will also find that dahlias are quite difficult to grow in Florida because of the heat. Another option is to plant the tubers in the fall if you have access to them at that time of year.
What about pre grown dahlias? I have one I bought as an already good sized dahlia, it bloomed a beautiful scarlet red with white tips but since I cleared the dead head it has not bloomed again! Could it be the size of the pot holding it back? Hi — Dahlias require at least 6 hours of direct sunlight each day in order to have the necessary energy to produce flowers. They are not indoor plants, nor will they bloom in the shade. Hopefully you can find a sunny place to put this plant — or offer it up to a friend who has a sunny spot and will share some flowers with you.
I bought an expensive selection of tubers and planted them in late March. We have had a lot of rain in SE England this May. Not one of the tubers has grown. Should I still hope they will? Hi — Plants that grow from bulbs, tubers, corms and other such storage vessels can have a hard time getting started in cool, wet soil. If I were you, I would dig up some of the tubers and check on them. If they are firm and you see some sprouts, put them back and be patient. Hopefully next spring will not be so wet.
To avoid problems in the future, consider starting these plants in pots and then transplanting them into the garden once they are in active growth. Hi, I live in Hertfordshire and planted lots of new Dahlia plants only to have had them totally desecrated by slugs.
I even used slug pellets but they still eat them. Some of the smaller plants have disappeared altogether, the taller plants have had their flowers eaten but the stems still appear to be ok. Will these dahlias come back? Hi Bernice — Sorry to hear you are fighting slugs. They can cause so much damage, especially to young dahlia plants. I have noticed that some years the problem is much worse than others, probably due to weather as well as population booms.
Though losing buds and foliage does set the plants back, they can usually recover. Even dahlias that have been eaten to the ground will often re-sprout and survive. Keep it up with the slug pellets I spread them twice a week when we are in a rainy period. I now use slug pellets that contain spinosad, which also kills earwigs. Hello- is it possible the color changes after season?
I kept the bulbs in the ground did not dig to store during winter. Is that possible? Hi Lorna — Yes, this does seem to happen. Tubers that produced flowers in one color can shift and begin blooming in an entirely different color. My dahlias were growing great, then suddenly several started wilting and flopping.
I dug up two and found mushy tubers. I have clay soil amended with compost, but I think the soil is still too heavy. Should I dig up the remaining plants and place them in grow bags? Hi Amber — Dahlias do hate soggy soil. The following notes will help you to add spectacular blooms and brilliant color to your garden! There is a huge range of colors and forms of dahlias. Just pick a couple and get started! You will enjoy spectacular color, variety and abundance of blooms from mid-July through the end of the growing season.
There are several ways to get your first plants. Most major garden centers now sell dahlia tubers; that can be a very convenient way to get started fig 3. Virtually every dahlia society has tuber and plant sales; they also welcome guests to those events. There are a number of advantages to this approach if there is a club near to you see list on this site.
Perhaps of greatest benefit of that source of tubers or plants is the availability of expert advice on your choices! The tubers at a society auction will also likely be locally grown and of good quality. Of course, there are also small businesses that specialize in selling dahlias and dahlia materials by mail order or internet see supplier list on this site. These suppliers are real experts on dahlias and their products are reliable and of good quality. Your tubers can go directly into the ground in the spring when the ground has warmed and there is little chance of frost.
One good guideline is to plant in the same time frame as you would a tomato. If you want blooms as early as possible, you can start the tubers indoors fig 4 in good light about a month before planting time.
You will then have a small plant ready at planting time. Dahlias can be planted as late as mid-June in most parts of the country. My dahlias do not have seeds in them, when I dead head them. I wonder why, can anyone tell me. Is it normal for my dahlias to brown almost every day?! I seem to find myself deadheading spent flowers everyday! Hi Johanna Individual blooms should last a few days. I recently bought some plants at a garage sale.
Do my dahlias like morning or afternoon sun? And do you have any tips on the transplanting? I was just going to cut away the planter and set the whole thing in a large enough hole… thanks, Pat. But they originate in Mexico, so you climate should be fine.
It could be too much water, or too little, or too much fertiliser or too little, or scorching from hot sun. The best recovery regime would be to cut back all the dead or dying stems.
Make sure the plant is reasonable well watered, then mulch with an organic compost. More info here. Hello Martin, i want to say thank you for all your insight, knowledge, and time you give to answering peoples? I dreaded headed my plants about 6 inches under the bloom and now the stem is brown where I cut but green everywhere else.
I also was using standard kitchen scissors new gardener here, just ordered shears! I tried cutting back a few more inches the first time I noticed they were brown, and it just happened again. What can I do to get them to start growing again? Hi Joan You need to cut back to just above a leaf bud, below the flower.
The part of the stem you cut back inevitably goes brown, so if you cut it back to the nearest bud, you minimise the stem die back. Do you trim back the leaves and leave stems on dahlias? Actually over taking other plants in pots with em. Thanks so much! Hi Denise Look out for tiny buds between the leaf axils. Look out for tiny buds in the leaf axils where they join the stems. Too much water?
Too much sun? It was root bound when I bought it, and this metal bucket was the only thing big enough I had to use. Plus it looks pretty cool in this bucket! Any suggestions? Thank you in advance! In my garden, I have 5 clumps of dahlias.
Suddenly, all 5 have started to die. Two started first and then the rest followed suit. I am so disappointed. We have had really hot weather and are on strict watering which is all by hand either by hose or watering can. I feel like I have been pretty good about watering, but it could be a factor. Nothing else has died. I could probably dig up one plant, but I would not have any idea of what I would be looking for. Reading the above suggestions, I could cut the plants.
I would really appreciate any help you can give me thank you. It sounds like the tubers may have rotted, but that seems unlikely if you are on water restrictions — unless there is poor drainage around them. Otherwise, it could be some bug at the roots — Cutworm or such like. Also check for earwigs in the leaves and flowers.
Martin, this is my first year growing dahlias. When they first started to bloom, they were a very vivid red color. Now they are starting to fade on the sides and turn an orangish color. Is there something I can do to make the color of the bloom look more vivid again? Hi Paige You could try a fertilizer which is higher in phosporous than other nutrients. I just did a round of dead heading in my garden. I live in Los Angeles, CA for reference, and my plants are starting to go a bit brown and sad looking.
We have had a good couple weeks of heat and dry weather. I am trying to bump up my watering. Should i add some Sluggo to my plants? Sounds like it could be the heat Sandra. Keep up regular watering.
Mulch with an organic mulch. Maybe use a seaweed foliar feed. They are in full sun and well fed and watered. They bloomed beautifully for about a month. Then it kind of just stopped. The remaining stems are roughly 2 ft tall and falling over now and not producing any more buds.
Should I cut the plant down? Sounds like if there are no bus, you may need to cut right back Matthew. But have a good look in the leaf axils. Sometimes there are some tiny buds hiding there. Hi there! Thank u! Apologies for not keeping up with comments. Been working on another project: The Self Determined Life. Nothing to do with gardening, but you might like it, so take a look and sign up for the newsletter.
Hi Martin, We live in Toronto. This is our first attempt at growing dahlias and had amazing results this summer. It looks like I did that a bit too early. Will my tubers not have eyes for next year? My question to you is, do I have to wait till the first frost to pull out the tubers for storage? Hi Aishafik, sorry for the delay in replying. They should be ok. Follow the advice here. Hi I wonder if anyone could tell me how to keep my tubers over winter I have just lifted them and very wet and soiled up I live in the midlands uk And it is very wet here?
Hi Cliff, sorry for the delay in replying. Hey my dhalias are growing pretty fine in the bed. But the ones in the pot have got leaves turning black and the leaves are dry to touch. We have had quite windy nights past week. Please help. Hi Erum It could be the wind, especially if it was hot and dry. Prune off the damaged leaves and give them a good water and mulch.
