Dahlia - white substance on shoots?

I couldnt find anything alive. The white stuff is as fine as talc powder or dust. I'll get some better photos tomorrow.

Thanks Bob, I shall take more photos tomorrow as the problem is getting worse by the day with the young plant being covered in the white pwdery substance.

My greenhouse is full of young seedlings and plants but its only affecting my Dahlias. I purchased them as tubers just a few weeks ago from a well known online seed supplier. Im wondering if the tubers were already affected before I got them, seeing as no other plant is affected?

Well despite lots of internet searching and reading about applying fungicides, I cant find reference to any particular type/brand. Any suggestions please?

Thanks Bill. Ill do some research on suitable UK fungisides. The problem is getting worse each day, its like someone has sprinkled talcum powder all over the plant. I wipe it off but it returns.

Thanks. When you say Q tip do you mean a cotton bud? Which fungiside would be best if needed?

In my greenhouse my two recently planted Dahlia Arabian Knight tubers are just poking through the compost in their pots, but they have both developed a white substance on the shoots.

They dont look like eggs but seeing as I have lots of other different plant seedlings in the greenhouse that arent affected im wondering if its something specific to Dahlias?

Growing Sweet Peas

Ive sewn 2 seads in each pot and they all seem to be germinating well. Should I thin out the weakest plant in each pot, or leave them alone?

Could it have been one of the gardens at the televised Gardeners World Live show at the NEC? Or even perhaps one of the Chelsea Flower Show gardens?

How to prune these plants

Laurel hedge. Cut it back however you want, and it will grow back. I have a very large laurel hedge and I lop the top 2 metres off it each spring. By the end of summer it has regrown to its original height.
