Hi I live in S Florida and will be trying to grow Dahlia's for the first time. Just wondering how long does the stalk have to be to transfer from pot to soil? Also, wondering if anyone on the forum have experience with growing Dahlia's in South Florida successfully?

Hi Welcome!

Many people plant dahlias before they have grown any sprouts at all. If you read the info at the Swan Island Dahlia site, they suggest that if your tuber has grown a long sprout, to snip it down to 1" when you plant it, however that is directed at people who havent potted them up first. I plant mine at what ever stage they are when I am ready to plant. Right now, some of my dahlias are close to 12" plants, some have just barely eyed up and started putting out roots, and everything in between. You just have to be really careful with the sprouted ones and dont break the sprout as they go into the ground. If the sprout breaks off at the base, it will most likely re-grow, but it will take a while.

I am in WI, so not much help when it comes to growing dahlias in the tropics. On another site I frequent there is a gentlemen from FL (not sure where) who talk of planting them out in Feb, his are full sized plants and starting to bloom now. He says his plants go pretty much dormant in the full summer when the heat really kicks in, and then begin flowering again in the fall. Apparently there are some dahlias that are ore heat tolerant than others, but I am afraid I dont have a list for you.

Good luck with them!

Thank you Mandolls, for the information. I actually planted two yellow passions from pot to soil earlier today only to find an iguana hanging out near the site. I didn't think much of it, well, about three hours later I decided to check on the site, only to find one of the yellow passions eaten completely, I could barely see the stalk. Hurtful, in less than four hours it was eaten all the way down. I will be visiting Home Depot tomorrow to buy some sort of iguana repellent.

Sorry to hear of your iguana problem. Are they common there? I had no idea that they could grow to more than 5' long and weight 15-20 pounds until I read about the problems they are causing with fruit farms in Puerto Rico. Entire crops of bananas, mangos and papaya are being destroyed. Various groups are issuing free pellet rifles to farmers to help control them. The population is estimated at over 4 million and growing rapidly. In three days, one group took over 300 in just a 100 yard area. And I'm complaining about a few rabbits! I hope you can get rid of yours. Supposedly, they taste like chicken. LOL No thank you! I'll pass!

OMG. iguanas. Yup. And all I have is slugs. I wonder what is causing the explosion in their population. Surely something 'we' have done

Can anyone please tell me why might my dahlia in the first pic be drying out. It's been raining a lot but it's in well drained soil and only this one looks like this. I've also been spraying it to keep snails and iguanas away

@Oberon46, the soil was mainly sandy but I have since removed it due to tuber rot

Interesting. You would think that sandy would drain well. Maybe it just clumps around the roots.
