Greenhouse Gardening Tips

Signs of Plant Stress: Wilted Leaves, Dry Tips, and Pale Appearances

This summer I started a long-distance move and after an extended period away my greenhouse plants are crying - yes crying - for help. Wilted plants, dry leaf tips, pale leaves and poor appearance. The trouble, it turns out, is that my house sitters were overly cautious about watering and using the fertilizer I left out for them. Now that I am home, I am growing my plants back to perfection.

Importance of Soil Amendments & Nutrients in Greenhouse Gardening

A few years back my greenhouse tomato leaves were purple, yellow and spotted. Not all at once, but over time and on different leaves. It was the second year I was growing in my greenhouse and the commercial potting soil I bought was low on phosphorus, nitrogen and potassium. The leaves on the plants were telling me what was going on. And it didn’t look good.

Sterility in the greenhouse sounds somber but in a few instances, it truly matters and saves gardenersfrom hassle and disappointment. Here is where I heed caution.

Truth be told, I can easily ignore a bit of soil spilled on the benches or an occasional unsterilized pot for seedlings. I don't always wear gloves, or fastidiously wash labels. I like the results in my greenhouse. My Sweet Peas bloom early, my tomatoes grow fat on the vine. A little mess, a few germs - my plants and I are no worse for the wear.
