Gardener's Question Time Nov 2017. |
|
- I have a Japanese Acer in a tub , and have had it for about 10 years. Every year towards the end of August the leaves shrivel up and fall off.
- Dahlias......when to bring on in spring. This year I followed Monty Don’s advice it was far too soon ended up with very leggy shoots which made for very tall plants. Can you pinch out? Do you need to lift tubers down here or can you chance it and leave them?
- Roses. Can you recommend the best spray for black spot and mildew and how soon to do it. Can or should anything be done over winter?
- Pansies: My winter flowering pansies appear to be being eaten by something. Have you any ideas as to what it might be and action to take?
- What plant subjects can be reasonably rooted in water rather then investing in special cutting compost?
- I planted both white and red onions this year and the crop of white ones were very good but the red onions were very poor. Any ideas why?
