I potted up a few Dahlias a month or so ago in my green house and they are now about two feet or more high so I planted them today. I have no idea if I should pinch them out.

I am waiting for 4 sets of leaves and at least 12" of height here. A couple are at 10", so I won't have to wait long

I also waited till 4 sets of leaves and it worked just fine. It slowered a little the growth but then they will eventually expolde. I did not pinched all my Dahlias but choose to pinch the most and leave one plant per species not pinched, just to see the behaviour. I noticed that the ones pinched slowered a little compared to the ones left alone. But the big difference I noticed is that the ones pinched will gets lots more branches=flowers than the others. And they must be tied to a stake and the unpinched ones could stay without.

The problem with not tying dahlias to a stake is wind can knock them down so fast.

@pirl , true! I forgot to point out that even the unpinched ones have a stake. I just did not use it yet as they look like a Dahlia tree, but I'm sure it will need a support before the end of the season.

Stakes are so good for easing the mind of the gardener when a storm blows through.

As for pinching to make a fuller plant...

I normally only pinch once. But after seeing that gorgeous Labyrinth, I might reconsider. I remember a skinny plant years ago that I didn't pinch. It was growing in an area that received little sunlight till after noon. It ended up being over 8' tall and produced only a handful of blooms.

We finally got a nice soaking rain a couple days ago. Some plants seem to have doubled in size since then. Natural rain water provides something you can't get from a hose. I used to argue with my dad trying to convince him that "water is water". Boy, was I wrong!

After the rain, the wind picked up without my noticing. There were gusts to 37 MPH. When I finally looked out, my plants were rockin' and rollin'. I went out and tied up a half dozen of the weaker ones and will do the rest in a few days. I've replaced 3 underachieving plants so far. One had a soft tuber and the other two had developed no root system at all. They were beginning to wilt and would have died/rotted soon anyway. There are a couple more that might be exiled. I've also been cutting off the multiple stalks on some plants, leaving only one. I think that makes for a stronger, healthier plant and makes it tons easier to keep it tied to the stake.

Two things I've learned over the years: #1 Any plant that dies, rots, doesn't bloom, has a virus or is dug up by an animal, will almost always be a favorite and/or is your only one of that variety. So far, I've lost at least six one-of-a-kinds. And...#2. You couldn't kill one you don't like or a mislabeled one if you tried! Murphey's Law?

Haven't had a chance to check on the forum much lately. I'd like to welcome grahambond to the forum and thank you for posting photos while the rest of us are waiting for our own dahlias to bloom.

I've lost exactly one dahlia so far. It was the one that I paid the most for and the only example of it - so yeah, my situation is in agreement with the rules.

This year has been s learning experience for me. I had my first blooms the end of May. This is my first year doing dahlias. It's a challenge to grow them in the Florida Panhandle but it can be done. I've lost several do to wind and a lot of rain. So I think I will grow extras next year maybe in pots. I don't know how the big ones will like pots but I'm going to try a few. Picture is my first blooms I had in May.

melodymart64. That is one gorgeous dahlia. I tip my hat to you. and Welcome!

I hope more do well for you and they will grow just fine in pots next year. The rain and wind in Florida can be a issue. I hope they all have plenty of blooms and beautiful colors when the others bloom . Dahlias are a fav of mine and they grow well here in Oregon . All my dahlias are from Swan Island Dahlias here in Oregon one of the largest mail order companies .Check out the dahlia photo contest under dahlias string , lots of Dahlias posted there.

Your yellow dahlia looks familiar. I tip my hat to you.

Many thanks for all of your most useful advice which I have noted down to study properly.
