Extend Your Growing Season: Build A Greenhouse
If 2010's frigid manifestation of global "warming" teaches gardeners anything, it's the utility of a greenhouse. You can purchase a small greenhouse kit online, or build one using inexpensive materials. The following web site has links to various plans:
Build A Greenhouse
Down here in southeast Texas, winter temperatures seldom dip below the 30's Fahrenheit. But we do get cold snaps taking us down into the 20's (which is still balmy compared to conditions farther north).
The wind from advancing cold fronts can be a bigger problem than the cold itself, as I discovered to my chagrin the other day. A strong gust tipped over my outdoor growing shelf, spilling all of the seedlings and soil into a jumble. I saved most of the plants, but now the varieties are mixed up and I don't know which breed of tomato or pepper is which. God has shuffled the deck, so to speak. This will make separation of the varieties (to inhibit cross-pollination) difficult, so I'll have to make liberal use of tulle fabric shrouds over unfertilized tomato and pepper flowers. These flowers are self-fertilizing.
Although I'm highly satisfied with my newly purchased Juliana 4-tier growing rack, I quickly learned the importance of keeping it well-ventilated during sunny days. Several seedlings were cooked last week because I neglected to open and roll up the front flap. It takes little time for a greenhouse to become too hot. Check your plants frequently! You might also want to install a thermometer.
