Ornamental and fruit trees are expected to begin blooming this week in home gardens and along the Blossom Trail in eastern Fresno County.
Gardeners are advised to check their sprinkler systems and turn them off when rainfall is sufficient. It is important to ensure that trees receive enough water, but overhead irrigation should be avoided if frost is forecasted.
Pruning tasks recommended for this period include evergreens, shrubs such as pittosporum and podocarpus, as well as deciduous trees and fruit and nut trees. However, apricot, oleander, and olive trees should not be pruned at this time.
Fertilization of fall-planted annuals and perennials is suggested. Gardeners should also apply one-third of the annual fertilizer amount to deciduous fruit and nut trees.
When planting new plants, gardeners are encouraged to consider each plant’s light requirements by placing shade-loving species in shaded areas and sun-loving species where they will receive adequate sunlight. The bare root planting season concludes in early February. This week is suitable for planting asparagus, cabbage, and chard.
Plants currently thriving include snapdragon (Antirrhinum), calendula, Lenten rose (helleborus orientalis), crocus bulbs, camellias among trees and shrubs, as well as bok choy, cabbage, chard, and grapefruit among fruits and vegetables.
Gardeners are reminded about the ongoing risk of frost damage; almond blossoms, citrus fruits, and avocados can be damaged if temperatures drop to 29 degrees Fahrenheit or below.
