Strawberry feed

[robin dearde]

Whats the best Strawberry feed?
For Strawberrys in:
Growbags, Potted in John Innes II , Potted in Genie 2.
The compost is now past the 6 weeks then feed point - so time to feed them.
How much - do you drench them in feed or just a bit and how often.

I have quite a lot - some summer varieties and some perpetual.

Thanks for any answer.

I would just use tomato feed once a week. Increase the rate if they begin to look starved.
