The April Vegetable Planting Guide is a UC ANR The Savvy Sage article published March 30, 2026; the page byline is Deborah Cunningham and the body credit says article by Peg Smith.
April is a transition month between cool-season and warm-season crops.
As soon as the soil is warm enough, transplant tomatoes, peppers, and eggplant.
Transplants have enough time to produce healthy vegetative and root growth before the summer heat and fruit production.
With warmer temperatures, squash and melons can be direct-seeded in the ground.

Keep generic squash unlinked because the catalog only has winter squash examples.
Use priority catalog links as crop-row examples, not UC cultivar recommendations.

These catalog entries match crops covered by the regional timing source; variety-specific details remain tied to each seed entry's own source.
