FAQs
Can I plant tomatoes directly in the ground in April in Houston?
Yes, April is a great time to transplant tomato seedlings into the ground as the risk of frost has passed and soil temperatures are warm enough.
How often should I water container plants during Houston's April weather?
Water container plants daily or when the top inch of soil feels dry, as containers dry out faster in warm spring temperatures.
Is it necessary to fertilize raised bed vegetables in April?
Yes, applying a balanced fertilizer every 3-4 weeks helps support vigorous growth during the active growing season.
What are signs of heat stress in young plants, and how can I prevent it?
Wilting, leaf curl, and yellowing indicate heat stress; provide shade during peak sun hours and maintain consistent watering to reduce stress.
Can I start seeds indoors for fall crops in April?
In Houston, April is generally too early to start fall crop seeds indoors; wait until mid to late summer for best results.
