Greenhouse Strawberries

[john1066]

My strawberries in the greenhouse are doing well! Is there a fertilizer that would make them even better? Larger flowers?

Strawberries in the greenhouse! It’s great! How long have you been cultivating strawberries in the greenhouse? As far as I know, universal fertilizer for strawberry is complex: 10 g of potassium salt + 80 g of ammonium nitrate with superphosphate + 10 liters of water. Use this solution every other week. And I also know that flowering plants need boric solution spraying. You should dissolve 1 g of boric acid in 1 liter of water. Good luck!

Many of the commercially grown strawbs are grown in poly tunnels (off ground) to produce early crops and ease of management.
I would think a tomato fertilizer, fed fortnightly would be ideal.

Don't forget to allow some fresh air and access to pollinators on warmer days.
