Too much leaf, not enough fruit.....

[moorlander]

Hi all,
A query. My strawberries have produced lots of leaf, but little fruit. My courgettes are similar both were well mucked. All rather disappointing. Wonder if I over did the muck. Could it be a lack of potash? If so can anyone suggest a good source?
Thanks everyone.

too much feed before the flowers have set on strawberries can result in a poor harvest but courgettes shouldn't have that problem. you probably just need to wait for the courgettes, they do like to grow a substantial amount of green before they flower.

wood ash, comfrey leaves or potasium sulphate (sold as sulphate of potash) are good sources.
