my hebe looks dead

Question

I purchased 4 hebes in April, approximately 8 inches wide and high including the frozen flame and purple shamrock variety. When I went on holiday for 2 weeks in May and there was extreme heat in England and when I returned they were all shrivelled up. Will they recover and is there anything I can do (e. g. cut them back)? They were beautiful plants. Also, my 13-week early potatoes are now on 17 weeks and I am lucky to get a handful of tiny things from a potato sack that has had 5 seed potatoes in. My tomatoes are also not doing too well this year. They have a white sort of fungus developing around some of the fruit and leaves, which have then dried up and fell off. They are in a greenhouse.

Answer 1

The hebe are likely dead, but check the bases and see if you can feel anything firm. If it is dried at the base and not firm, they are dead. If there is still some green, firm stems at the base, it may come back.

Poor potato yield is normally caused by it being too warm or poor nutrition in the soil. You mentioned that it had been very warm, so this was likely the cause in your case.

You can treat your tomatoes with a fungicide and this will clear up the fungus. If you can improve the air circulation around the plants, like with a fan, this will help with preventing the return of the fungus.
