Frost

Posted by John Fulton -

If you are ready to have the season conclude, harvest what you can. A freeze is worse than a light frost, as damage may actually occur to thin-fleshed crops such as tomatoes. The main things to harvest prior to a frost or freeze include squash, pumpkins, cucumbers, melons, tomatoes, etc. Virtually everything in the garden will be affected except for frost tolerant crops such as lettuce, spinach, radishes, and the like. The main problem with any of the vining crops is the possibility of the vines rotting back to the vegetable. This in turn means they won't keep well. Unfortunately, vining crops harvested early won't continue to ripen. Green pumpkins tend to stay green.

For tomatoes, you may pick green tomatoes and they will ripen after a period of time. The best way is to pick firm, good quality fruit, and wash well with soapy water. After they are dry, wrap in newspaper or tissue paper and place on a rack or in a cardboard box in a single layer. Check periodically for tomatoes going out of condition, or becoming ripe. To speed things along, you can try putting a tomato in a paper lunch bag with a banana peel. Bananas are high in ethylene, which is the same thing used in a gas form to ripen tomatoes in transport during the winter. Of course, the flavor just isn't the same as a vine-ripened tomato, but tomatoes in the fall or winter are good regardless.

As for flowers, the same principals of protection apply to annuals. Of course if you have hanging baskets or potted plants, you can simply put them in a garage or shed until the danger of frost has passed. The key point is one or two nights of frost, followed by a week or two of good weather, probably justifies some protective measures. A frost every night for two weeks, or a long period of freezing temperatures, probably mean major efforts will produce very little gain.
