FAQs
Can I plant tomatoes directly in the ground in April in San Antonio?
Yes, April is a good time to transplant tomato seedlings outdoors as the risk of frost has passed and soil temperatures are warming.
Should I water raised beds differently than containers in April?
Containers dry out faster than raised beds, so they typically need more frequent watering, especially as temperatures increase.
Is it safe to plant leafy greens in April here?
Leafy greens tend to bolt quickly in San Antonio’s rising April heat, so it’s best to avoid planting them now or choose heat-tolerant varieties.
How can I protect my plants from late cold snaps?
Keep frost cloths or row covers handy and monitor local weather forecasts to cover vulnerable plants if temperatures drop unexpectedly.
What soil preparation is recommended for April planting?
Enrich soil with compost and ensure good drainage, especially in raised beds and containers, to support healthy root development during warmer months.
