Sounds to me like you have a nitrogen rich soil. Lots of growth and no fruit. Perhaps you could add some bonemeal to the soil. You may still be able to get some produce off your existing plants if you try applying a fertilizer with a higher phosphate ratio. The fastest way to have it take effect is to foliar feed, directly spraying the solution onto the foliage first thing in the morning. You can use a binder such as yucca root extract (Thermax) or I’ve heard egg whites work well too.
I went out and purchased a soil testing kit. Figured I might as well see what my PH, Nitrogen, Phosphorous and Potassium is.
On a good note. PH matches perfectly with the chart for 7. Nitrogen, phosphorous are next to nil and potassium looks to be too high. Then I had a thought. Last year I used Mel’s mix. I wondered if it was possible that with the soil compacting and just egg shells and veggies as additional compost maybe it is time to say screw it, add the fertilizer, till under everything and start fresh.
This will probably be next weekends activities for me. Any suggestions?
