Hello, this is my first posting.
I grow plants, mostly perennials, to sell for charity. This year I have planted some hanging baskets and pouches with a variety of annuals, mostly plug plants. In the last couple of weeks the Busy Lizzie leaves have started to yellow and I am wondering if I am over-watering, underwatering or not feeding enough. I am watering whenever I can not squeeze water out of the bottom of the basket/pouch and am feeding once a fortnight as recommended on the liquid feed container. There are slow release granules mixed into the compost.

I read somewhere on here that baskets should be watered morning and night, 3 times at each session! Rather concerned about doing that up here in Scotland.

Any advise would be gratefully received.

Thank you
