Garden Notes January 2026
In Zones 8a and 8b, January is the coldest month of the year, but the climate is still relatively mild compared with northern zones. Most gardens are dormant, and this month is focused on planning, maintenance, and preparation for the upcoming growing season. Tender crops are protected, and winter vegetables continue to provide harvest where possible.

Most planting is postponed due to cold temperatures.
In 8b and protected areas of 8a, you can sow cold-tolerant crops indoors or under cold frames:

Keep garden beds clean of debris to prevent overwintering pests.
Mulch beds to conserve moisture and protect soil structure.
π FRUIT CARE β JANUARY
Fruit trees and berry bushes are dormant.
Light pruning of dormant trees can be done (except peach/plum which may need late winter).
