Limiting Factors—Cold!

February 4, 2013

If you were in the Sonoran desert in January 2013, you may well have experienced a limiting factor that many people would not expect in a desert: freezing damaging cold.

In many places it dropped into the 20’s or lower at night, for several nights, enough to nip many buds in the bud.

Native plants, which have been through this before, generally survived quite well, but imports, or annual vegetables, either got crisped or completely melted down.

This suggests that planting native species has even more benefits than we usually consider.

Plant vegetables NOW?

February 15, 2011

Now that we’ve had another hard freeze in the Sonoran desert that burned the tops off many shrubs, and melted tomato and pepper plants down to the ground, February may finally be time to plant again. But have your frost covers ready, just in case.

Tomato and pepper seedlings need to be transplanted now to give them a chance to ripen before the summer heat bakes them.

And all kinds of salad greens and onions can be planted as seeds or seedlings for a good crop. If you plant seedlings of lettuce, beets and chard, they will begin producing salads within a week or two, and continue into early summer.
