It's the same answer as for the Sambusca. It's just winter
Pat, that's a Hugh amount of food! My OH, is v large, only managed 2 slices when we were in Aus in Feb!
I think it's Slime Mould. RHS suggest it can be dissolved by watering. 2nd attempt to post this
They could be molehills. If you clear away the soil you may find the hole that the mole pushed the soil you of. I try to push as much of the soil as possible back into the run.
You can split the tubers but each bit MUST have a bud. It's easier to see in the spring when the new growth starts. I take mine out of pots for the winter as I can check the tubers for Vine weevil grubs that love dahlia tubers and will eat them
Home composting is unlikely to kill the seed. Our domestic heaps just don't get hot enough
I'd go for the darker one as it is older wood. It would be worth a quick check to see how many branches it has higher up in case it leaves an odd shape.
Do not put nettle roots or seeds in as they can survive in homemade compost so you could end up spreading them around you garden
Thanks Dove, probably down to watering. Since we went to metered water I try not to use too much.
Some of my healthy looking courgettes are actually hollow. There is no sign of any pest damage. Does anyone know what may be the cause?
