By Lynn Gillespie. By Kelly Lehman. 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.

Can I cut them back to just above the bulbs and dig them up, then leave them to dry out for replanting next season?? Yes that would probably work. Leave it as late as possible. Thank you!!! Just after I started giving them TLC and deadheading them, I started questioning if I butchering the beauties instead!

Lisa in 7b. I bought some beautiful Dahlias for the first time at Costco. I planted them, forgot the snail bait, and when I checked on them the next day, something had made quite a feast of them. I have since put down some Deadline to deter the pest, but they are not snapping out of it. Been a few weeks. They look a little droopy and, well, very eaten. How do I perk them back up?

Hi Joy, maybe something is still eating them. Check for earwigs. They like a meal of dahlias. They are curved downward and the leaves are curling in from the sides.

They are beautiful, but I am wondering if these can be saved and grown again the next year. I went to every garden centre looking for tubers, and everyone was sold out of 18 in to 24 in. All that was left was these potted hybrids.

Hi Adrienne. You can try them but they may not be strong enough to regrow next year. Check how big the tubers are at the end of the season. I want to know if hybrid dahlias can be taken in and kept until the next summer.

Do they have a tuber the same as regular dahlias. Just do it carefully and it should work. I dahlias used to have perfect blooms but not buds are only partially opening and when they do the flower is deformed pedals are asymmetrical, some short others normal.

In addition to that I now have white lines on my leaves probably leaf miners. Are the two problems from the same pest? Hi Nathalie. Sounds like leaf miners on the leaves. Have a good close look at the plant to see if you can see any critters. Hi there, One of my plants recently got attacked by aphids! I read somewhere to spray them with soapy water and then spray with the hose to remove them the next day, but it looks like I was too late.

If I cut stems right down, is there any chance they will come back? Hi Michelle, Yes, if you cut them down they should come back. Dahlias flower late anyway, so depending on where you live and how early the first frost is you could still get flowers this season. Maybe you just need to cut back the damaged sections, not right down to the ground.

I planted my dahlias in mid-May and to date have not seen any growth. I dug one up and found it to be still firm and just beginning to create roots. What am I doing wrong? As long as they are well fed and watered, just give them some more time. I am planting dahlias in plastic pots for the first time.

Can I leave the plants in pots and bring inside during the cold Canadian winter? Can I then divide and repot plants in spring. The plants have buds and blooms now. Last year my dahlias were a brilliant pink. Do I need to add something to the soil? Hi Rob Sometimes this happens when the plant is stressed. All divisions of one of my decorative class dahlias has reverted to semi-double this year. Will this condition persist again next year? I have been growing dahlias for many years and started out with several different colors but every year I seem to get more and more maroon with white tips and this year that is all I have except for my small yellows ones that stay the same.

What could be making these change colors? Hi Guys i have orange Asiatic Lilies i was wondering is it ok to cut back all foliage as there is new sprouts starting to form on the bottom or do i leave it alone, it had flowered through June and i cut flowers but left all foliage. What should i do now? Hi Sabrina Lillies are bulbous plants. The leaves generate energy by photosynthesis that is stored in the bulbs. That way the plant can generate enough energy to store for flowering next year.

The plant itself has grown very large. There are TONS of buds everywhere. But where? Dahlias usually flower mid to late summer. Wilting can be over-watering or under-watering, so you need to see which might be the problem.

Usually full sun is best, or maybe an area with afternoon shade if the sun can be very hot where you. Is there any way of speeding up process to get flowers to bloom? I have read through all the questions and do not see an answer to my problem.

I puchased a XXL Durango Dahlia this spring, it was in a pot about a gallon size, had about 6 lovely flowers on it. It was in full sun all the time. It would not do anything in the pot I put it in and all the leaves wilted and then fell off, some new small leaves did grow but then they also turned pale green and fell off.

I could not believe the small size of the tuber for such a large plant. I now have it stored in the fridge in a ziploc bag and peat moss so I will try and see if I can keep it over winter. I have grown dahlias for years and not every had a problem with growing them until now but they were always in the ground and not in pots.

If you have any ideas what could be wrong I sure would appreciate knowing as I would like to try this plant again and have no idea of what I did wrong. Maybe you gave it a bit too much water and fertiliser.

Remove and dispose of the old flower heads and pruned leaves from the flower bed after each pruning. Old plant material can attract insects or harbor diseases. Cut flower stems back further than the topmost leaf to maintain the shape of the dahlia plants if they have become overgrown or leggy. Jenny Harrington has been a freelance writer since Her published articles have appeared in various print and online publications. That will promote more blooms and avoid unslightly flowerless stems sticking out here and there.

See what I did there? Cool little tip, Erin. I don't grow dahlias. If they're still blooming now, it sounds like I better start. The only thing in bloom in my garden are sedums and "painters palette". Thanks so much for all your help. Finally have some great help from you. Great info!!
