Hi All!
I am relatively new to the world of permaculture (and gardening in general). Last season (spring), I built several large raised beds (3ft x 6 ft x 2 ft) that are elevated from the ground. I ordered 6 cubic yards of what I thought would be great soil from a local soil company and had it delivered by dump truck. This was obviously going to be more than I needed for the raised beds, but I thought it best to have more great soil than less.
The soil was called "nursery mix" and they tell me it is comprised of 50% nitro humus, 20% compost, 20% wood fines, 10% sand. The wood fines especially make it a very "coarse" feeling soil. I have attached a photo of the dry soil.
I filled the raised beds and several large pots with the soil and planted several summer veggies (tomatoes, peppers, melons, summer squash, scarlet runner beans, green beans) — some from seed, some from starts which I started from seed indoors.
Initially, things looked good, but very quickly, as the summer grew hotter, all of the plants grown in these beds suffered. I watered daily. But the plants browned easily, seemed more susceptible to pests, and were quite spindly. I tried various organic fertilizers, but none of the plants ever developed as I would expect. Then I planted a couple starts of tomatoes and peppers in new pots (this time filled with a potting mix amended with homemade compost). These plants have all grown quickly, with lush foliage, and healthy fruit set. The only distinct difference is the soil.
SO... I am trying to assess what may be going wrong with the soil I purchased. My best guess is that the soil is not retaining moisture and when I water, most is just running down and out through the bottom of the beds. I am watering by hand with a hose fitted with a sprayer.
Does anyone have a guess as to what might be happening? And any suggestions for ways to amend this container soil to improve the chances of my fall vegetables planted in the same containers?
Also, I have several cubic yards of the soil left. What suggestions do you have for it's best use, if not containers?
Thank you all for your help!!!
Best,
S
