Some Chilling News

Share

The chilling factor is an important consideration when you’re choosing apple or stone fruit trees, such as peaches, prunes and apricots, for a Southern California garden. These trees need temperatures of under 45 degrees Fahrenheit (contrary to what many think, freezing temperatures are not necessary) for a certain length of time. A chill needn’t occur all at once but can be intermittent. You would think that all plant life would be suspended at such temperatures, but actually this is when the buds for future fruit are forming.

Chilling requirements can vary within a species. For instance, some apples can grow only in extremely cold climates, while others get sufficient chilling in our mild climate. Among the newest for our area is the Gordon apple, which was discovered in Whittier. Then there are the Anna and Ein Shemer apples, which were developed in Israel (each of these two trees needs the other for good cross-pollination and fruit set). Before buying bare-root fruit trees, check the chilling requirement. Keep in mind that plants get more chilling on the north side of a house or wall--or even on a north slope.

Geraniums can go almost dry this time of the year. Those in the ground should get all the moisture they need from rainfall. Prune leggy plants after the danger of frost has passed. Healthy pieces make good cuttings, but let them sit for a while so the cuts can form a protective covering.

Fuchsias can be pruned as soon as there is no danger of frost--when the leaves are still present they give the plants a little protection from freezing temperatures. On the coast, this may mean pruning can be done now; inland it may be better to wait until March. Cutting the plant back now will force out tender new growth, but remember that fuchsias are very susceptible to frost and that you can lose them if you prune too early. When pruning fuchsias, bear in mind that they bloom only on new growth, so drastic pruning is needed.
