By planting in intervals of 10 to 12-days, you can pick fresh lettuce all winter as we do. If planting space is limited, seeds can be started in flats and transplanted to the growing beds as soon as one crop is harvested. When scheduling planting dates, remember that maturing dates increase as days grow shorter. This is one of the reasons for growing greens rather than root vegetables. With a solar greenhouse, it takes almost 5-months for root crops to attain sufficient size for harvesting, but greens are ready in less than half that time.
Root crops do well in garden beds.
The deep beds provide heavy, strong growth from all plants. This can be added to good garden loom which has been tested and has all the needed nutrients for good healthy growth. Examine plants carefully for insects before placing them in the greenhouse. Any showing signs of insect damage should be discarded immediately. If you are an old hand at growing vegetables in a solar green-house, you probably have everything in readiness for September or October planting.
