June is a crucial month for tomato plants. Proper care during this time ensures a healthy harvest later in the season. Here are the top 10 tips to keep your tomatoes thriving in June.
1. Water Consistently
Tomatoes need about 1-2 inches of water per week. Water deeply at the base of the plant early in the morning to prevent diseases and encourage strong root growth.
2. Mulch to Retain Moisture
Apply a 2-3 inch layer of mulch around your plants. Mulch helps retain soil moisture, suppress weeds, and keeps the fruit off the soil, reducing rot.
3. Fertilize Regularly
Use a balanced fertilizer or one high in phosphorus and potassium to promote flowering and fruiting. Fertilize every 2-3 weeks for optimal growth.
4. Prune Suckers and Lower Leaves
Remove suckers—small shoots between the main stem and branches—to direct energy toward fruit production. Also, prune lower leaves to improve air circulation.
5. Support Your Plants
Use stakes, cages, or trellises to support tomato plants. Proper support prevents breakage and keeps fruit off the ground, reducing disease risk.
6. Watch for Pests and Diseases
Inspect plants regularly for pests like aphids, whiteflies, and tomato hornworms. Use organic or chemical controls as needed. Remove infected leaves promptly to prevent disease spread.
7. Ensure Proper Spacing
Plant tomatoes with adequate space—generally 18-24 inches apart—to improve air flow and reduce disease incidence.
8. Monitor for Blossom End Rot
Ensure consistent watering and adequate calcium intake to prevent blossom end rot, a common issue causing dark, sunken spots on the fruit.
9. Keep the Garden Clean
Remove fallen leaves and debris regularly to reduce disease and pest habitats. Clean tools after use to prevent spreading infections.
10. Harvest at the Right Time
Pick tomatoes when they are fully colored and slightly soft to the touch. Regular harvesting encourages more fruit production and prevents overripening.
