Seasonal Gardening Calendar for Garden Grove

Garden Grove’s Mediterranean climate supports distinct seasonal gardening activities that optimize plant health and productivity. Understanding this seasonal rhythm helps residents plan garden projects, schedule maintenance, and select appropriate plants for different times of year across all zip codes.

Winter (December-February): Cool temperatures and regular rainfall create ideal conditions for planting cool-season vegetables, ornamental plants, and perennials. This season is optimal for landscape design projects, soil amendment, and installing irrigation systems. Winter is also when residents should prune deciduous trees and shrubs during dormancy, clean gutters, and prepare beds for spring planting.

Spring (March-May): Warming temperatures and decreasing rainfall signal the transition to warm-season gardening. Spring is ideal for establishing annual flowers, transplanting seedlings, and planting warm-season vegetables like tomatoes, peppers, and beans. This season also brings increased pest and disease activity, making it important to monitor plants regularly and implement integrated pest management strategies. Spring is the best time for installing indoor herb garden setups for summer enjoyment.

Many gardeners reduce planting activity during peak summer heat but focus on maintaining established gardens, harvesting vegetables, and managing water use efficiently. This season is ideal for propagating plants from cuttings and planning fall garden improvements while observing which plants thrive in summer conditions.

Fall (September-November): Cooling temperatures and returning moisture create a second planting season nearly as favorable as spring. Fall is excellent for establishing cool-season vegetables, ornamental plants, and perennials that benefit from milder conditions before winter.
