When to Plant Tomatoes Outside in CT

Tomatoes are one of the most popular and versatile vegetables to grow in Connecticut. They are a great addition to salads, sauces, and many other dishes. However, figuring out when to plant tomatoes outside in Connecticut can be a bit of a challenge. Here are some tips to help you get started.

The Right Time to Plant Tomatoes in Connecticut

The best time to plant tomatoes outside in Connecticut is typically in late May or early June, when the soil has warmed up to about 60°F. Planting too early can result in stunted growth, as tomatoes do not grow well in cool climates. Additionally, late-season frosts can damage your plants if they haven't established strong roots yet.

Preparing Your Garden Bed for Tomatoes

The first step in planting tomatoes outside is to prepare your garden bed. The ideal location should receive plenty of sunlight and have well-draining soil. Amend the soil with compost or other organic matter to improve drainage and nutrient content. Avoid high-nitrogen fertilizers, which can encourage foliage growth at the expense of fruit production.

Choosing the Right Tomatoes for Connecticut

When selecting tomato varieties to plant in Connecticut, look for those that are disease-resistant and tolerant to our hot, humid summers. Some popular varieties for Connecticut include Early Girl, Celebrity, and San Marzano. You can also try heirloom varieties such as Brandywine and Cherokee Purple, but these may not be as disease-resistant as modern hybrids.

Planting Your Tomato Seedlings

If you're starting your tomatoes from seed, you should start them indoors about 6-8 weeks before your intended planting date. Seedlings should be transplanted outside when they have 2-3 sets of true leaves and are about 6 inches tall. If you're purchasing transplants from a nursery, look for plants that are stocky, with dark green leaves and sturdy stems.

Caring for Your Tomatoes

After planting your tomatoes outside, they will need regular care to ensure healthy growth and fruit production. Water tomato plants deeply and regularly, providing about 1 inch of water per week. Mulch around the base of the plants to help conserve moisture and suppress weeds. Support your plants with tomato cages, stakes, or trellises to prevent branches from breaking under the weight of heavy fruit.

Harvesting Your Tomatoes

Finally, the fun part: harvesting your tomatoes! In Connecticut, most varieties will start to ripen in August and September. However, the exact time will depend on weather and growing conditions. Tomatoes are considered ripe when they are firm but give slightly when gently squeezed. Store picked tomatoes in a cool, dry place, away from direct sunlight, and use them within a week or two for best quality.

With a bit of planning and TLC, you can enjoy a bountiful tomato harvest right in your Connecticut backyard. Happy planting!
