Delphinium problem

peter104roweZAeWFs63 · March 2023

Many thanks to you all for coming back to me. I have attached a photo. I had these delivered by a plant distributor so I would have thought they sent them out at the time for repotting. They came in a capsule folder of 5 different varieties (although one completely came out of the soil a week after I repotted). I placed them in my conservatory which is heated as I was afraid a cold greenhouse would kill them. I take it I will need to move them into the greenhouse.

They might be ok. Just leave them to settle in, but don't give them any extra heat. Any sun you get could be far too hot for them, even on a south facing window sill, let alone in a heated conservatory. It might be better to have them in a room which isn't likely to get so hot, and has a more consistent temp, but with good light. south west facing or similar. It's those swings of temperature at this time of year that are difficult for small plants.
They're quite a good size - I thought they'd be much smaller.

Why is one inside a plastic bottle? Is it just for support? If so, a few twigs or similar would be better

I forgot to say - the pots are a little bit big, so just be careful about watering. Don't water unless they really need it

I will move them into a cool unheated bedroom and see if they improve. Thank you all for advise, much appreciated.

Fingers crossed they'll settle and come away for you. It's always a little tricky at this stage for them.
As they grow and fill out, and once the weather improves and warms up, you'll be able to get them outside for a little while to start acclimatising them.

Watch out for slugs when you plant them out. The smaller the plant the more likely the slugs are to eat them.

I don't see any labels. Always a good idea, especially if they are named varieties. I wouldn't worry if they don't flower until next year.

Have you though of growing delphs from seed? Easy.

Hi, I have labels on the side of the pots. I sent for plugs as I could not find Black Knight seeds and this collection had that one. Unfortunately, it is one that is looking a bit sad, the stems go as thin as hair and just break off. I have set seeds from what I took from my garden delphiniums and they have just come through but they are not this variety. I have now put them in a window sill in an unheated room. I didn't water the plug roots when potting on but did water them in after. Hopefully they will pick up.

Another problem with plugs is that they sometimes are grown in a little tea bag material type bag, you have to tear this off and untangle the roots, it’s called teasing.
