My dahlias (which I have for several years) produced a lot of leaves but not a lot of flowers this year. Why was that and how can I increase flowers next year? I don't lift them in winter.
Sunflowers - have sunflowers in a pot and they were flowering but now have closed up. Can you tell me why they might have closed and what to do with them?
I have 2 growbags in a polytunnel each with 2 tomato plants. The leaves on one of the plants is wilting. If I'm watering incorrectly surely both plants in this bag should be affected ? What am I doing wrong?
