I have a great garden growing. Except for the eggplant and brussel sprouts. My plants are almost idle, growing barely. Same as last year. Is there a specific nutrient or Ph I am missing? Garden is well composted with a blend of sheep manure and wood chips, shredded leaves applied last fall and worked in. Fresh compost was added to the planting when the eggplant was transplanted a couple weeks ago.
We have had a relatively wet spring, yet everything else is thriving.
Leaves and certain types of wood chips are acidic. Some plants like acid soil, other don’t. You might need some lime. I put all the fall leaves from the yard on the garden, along with a healthy dose of chicken litter. Then, let it sit over the winter. In the spring it gets tilled in, along with some lime, a month or so before planting time.
Eggplants need warm weather and full sun. Too much water and they can get root rot.
I have a local garden center that blends their own fertilizers. Last year they recommended an all purpose type 10-2-12. on everything but root crops. The recommended a starter fertilizer with high phosphorus for them.
Everything thrived! You may want to look at your PH. I had to till in lye to bring the soil neutral.
Best of luck!
