When to Plant Tomato Seeds in Oklahoma

Oklahoma is a great place to grow tomatoes, but the timing of planting is important to get the best results. Here's what you need to know about when to plant tomato seeds in Oklahoma.

Starting Indoors

The best time to start tomato seeds indoors in Oklahoma is 4-6 weeks before your last average frost date. For most areas in Oklahoma, this is usually around mid-April. This gives the seedlings time to grow and mature before transplanting them outside.

Start by choosing a tomato variety that suits your growing conditions and personal preference. Some popular types of tomatoes for Oklahoma include Roma, Celebrity, and Early Girl.

Use a seed starting mix and follow the instructions on the seed packet for planting depth and spacing. Keep the soil moist and place the seed tray in a warm location, preferably between 70-80°F. Use a grow light or place the tray near a sunny window to provide enough light for the seedlings.

Transplanting Outside

Once your tomato seedlings have grown to a height of about 6 inches and have a few leaves, it's time to transplant them outside. This usually happens around mid-May in Oklahoma.

Choose a location in your garden that receives at least 6 hours of sunlight per day and has well-draining soil. The soil temperature should be at least 60°F before transplanting.

Before transplanting, harden off your seedlings by taking them outside for a few hours each day for a few days. This helps them acclimate to the outdoor environment and reduces transplant shock.

When planting, dig a hole deep enough to bury the stem up to the first set of leaves. This encourages more root growth and a stronger plant. Water thoroughly after planting and mulch around the base of the plant to conserve moisture and prevent weeds.

Caring for Your Tomatoes

To ensure healthy tomato plants and a bountiful harvest, proper care is necessary. Some things to keep in mind include:

Watering: Tomatoes need 1-2 inches of water per week, either from rainfall or irrigation. Water deeply at the base of the plant to encourage deep root growth.

Fertilizing: Use a balanced fertilizer every 3-4 weeks during the growing season. Be careful not to over-fertilize, which can lead to excessive leaf growth and less fruit production.

Pruning: Remove suckers (the offshoots that grow between the stem and main branches) to encourage larger fruit and better airflow around the plant.

Pest control: Watch for common pests like tomato hornworms and aphids, and use organic or chemical control methods as necessary.

Harvesting: Tomatoes are usually ready to pick when they are fully ripe and the skin is firm. Store ripe tomatoes at room temperature for up to a week, or in the refrigerator for a few days.
