Planting Bare Root Fruit and Nut Trees

Winter is a good time to plant bare-root fruit and nut trees. This allows their roots and shoots to develop when the weather is cool. When selecting a tree for your garden, you’ll need to consider both your climate zone (A, B, C) and microclimate conditions (wind, fog, elevation) along with the chill hours required for fruit production. See this article ( Selecting fruit nut berry tree for SM-SF counties ) for details.

 

A Frequent Visitor on Cole Crops

Have you seen this distinctive butterfly flitting about your garden? It’s the adult cabbageworm butterfly of the imported cabbageworm. The larvae (caterpillars) enjoy feeding on the leaves of cole crops such as broccoli, cauliflower, kohlrabi and, of course, cabbage. Protect your crops with floating row covers or netting.

Leave the Leaves

It’s fall and the leaves are falling. Instead of raking or blowing, use the free mulch to protect your soil and the living organisms in it. The leaves also will help to suppress weeds, prevent erosion and provide a winter home for many insects and invertebrates. As the leaves break down, they will feed the organisms living in the soil. If the leaves are diseased, remove and dispose of them in your curbside compost bin.

Get Ready to Plant California Natives

Fall is the best time to plant most California natives. Cooler weather and (we hope) rain get them off to a good start by helping them grow deep roots – perfect for seeds or transplants. Many nurseries and native plant groups have fall plant sales. In our introductory California Native Gardening web page, you’ll find inspiration and resources to help you get started and get planting. Check our All Events events for seed starting classes for natives and more. Get the basics on planting wildflowers here.
