Beet Tips for Yuba City Gardeners
- •Soak beet seeds 4 hours before planting to soften the tough seed cluster and improve germination rates.
- •Thin seedlings to 3 inches apart — crowded plants produce tiny woody roots rather than full-sized beets.
- •Succession plant beet in Yuba City every 2–3 weeks through spring to extend the harvest window into summer.
Common Beet Pests in Yuba City
- •Leaf Miner — peaks July in Zone 6a (active May–September); winding white trails in leaves; remove affected leaves and use row covers.
- •Flea Beetle — peaks July in Zone 6a (active May–September); tiny black beetles that riddle leaves with holes; row covers protect seedlings.
