Tasks
- Control cool-season weeds before they mature and go to seed.
- Plants planted last spring and fall may need water if rainfall has been inadequate.
- Run sprinklers periodically through their cycles to maintain clean lines and to exercise the valves.
Pruning
- When harvesting blooms for arrangements, make cuts with an eye toward shaping the plant.
- Prune and shape dormant deciduous plants – shrubs and perennials.
- Cut away 50% of last year's growth on peaches and nectarines.
- Remove leaves from roses in January to force the plant into dormancy. This is not necessary with shrub or groundcover roses.
Fertilizing
- Apply nitrogen fertilizer to citrus trees prior to bloom.
- Always read labels carefully before applying fertilizer. Use only if necessary.
- Bare root planting season continues.
- Peas (both edible and decorative varieties) can be planted this month. Before planting, soak dried peas between damp paper towels in a shallow dish. Cover loosely with plastic and keep towels moist. Plant seeds when they're just beginning to sprout.

- Remove fallen camellia blooms promptly to prevent petal blight on next year's flowers.
