FAQs
Can I plant lettuce in June in San Diego?
Lettuce tends to bolt quickly in warm weather, so it's better to start it indoors now and transplant in early fall when temperatures cool.
How often should I water container plants in June?
Water containers daily or as needed since they dry out faster in warm weather, ensuring soil stays consistently moist but not waterlogged.
Are raised beds better than in-ground for summer planting?
Raised beds offer better drainage and soil warming, which can benefit heat-loving plants, but both methods work well with proper care.
What pests should I watch for in June?
Common pests include aphids, whiteflies, and spider mites; inspect plants regularly and use organic controls if needed.
Is it too late to start tomatoes in June?
No, tomatoes can still be planted in June in San Diego’s mild climate and will produce well through the summer.
