Sacramento has a mild winter climate. With temperatures dipping typically to about 30 degrees. That means we can generally enjoy our plants year around.
Although there are some plants that require special care in the winter and need protection from the frost. Frost season is from mid-November to mid-March. Plants like citrus, succulents, ferns and tropicals should be protected and covered when temperatures are below around 40 degrees.
Frost cloth is a lightweight and breathable fabric. When temps are in the forecast below 40 degrees, we recommend watering your frost tender plants. Cold temperatures increases transpiration of plants and therefore plants can dehydrate faster. After watering your plants, cover them before dusk with frost cloth. Be sure to secure the cloth with a rock or a fabric staple to the ground. This keeps fabric secure with winds.
Frost cloth is better than using a sheet or a plastic tarp. Plastic can transmit cold to the leaves and burn the plant. Also heavy blankets aren't breathable and can break branches. Frost cloth can stay on the plant for several days because sunlight and air is able to penetrate the cloth and still reach the plant. We offer various sizes of frost cloth at the nursery.
Beyond frost cloth, pruning is an important topic in winter. Get your pruning shears sharpened and ready. In Sacramento late December and January are the best months to prune roses, perennials like lavender, fruit trees & more.
Another topic is Dormant Spray. Spraying a horticultural oil mixed with Copper Spray is a method for controlling many pests and fungus as the eggs are dormant. In other words, 3 rounds of dormant sprays to your crape myrtle, for example can reduce the pests like aphids and powdery mildew that tend to appear in spring and summer months.
Finally, winter is bareroot season. That means dormant fruit trees and roses arrive to the nursery. Bareroot season in the winter offers the best selection of fruit trees and roses at the best prices of the year. Check out our website for pre-ordering information for bareroot fruit trees and roses.
