How to Grow Blight-Resistant Tomatoes and Keep Blight Out of Your Garden

Tomato blight is every gardener’s worst nightmare—one minute, your plants are lush and thriving, the next, they’re collapsing in a soggy, brown mess. But don’t despair! By choosing blight-resistant tomato varieties and following a few key growing techniques, you can enjoy a bountiful, blight-free harvest. And let us  introduce you to one of our favourite new heirloom, blight-resistant tomatoes: Primabella.

Choosing Blight-Resistant Tomato Varieties

If you’ve struggled with blight in the past, the best way to fight back is by growing resistant varieties. You’ll be thrilled to know that some heirloom varieties can be naturally resilient.

One such star performer is Primabella, an heirloom blight-resistant tomato that’s taking the gardening world by storm. This vibrant red cherry tomato is not only packed with old-fashioned, rich tomato flavour, but it also stands strong against late blight, making it a must-grow for anyone in humid or wet climates.

How to Prevent Blight in Your Garden

While growing resistant varieties is a great start, you’ll need to take a few extra precautions to keep blight at bay.

1. Give Your Plants Plenty of Space

Blight spreads quickly in damp, crowded conditions. Keep good airflow by spacing your tomato plants at least 40 cm apart and pruning lower leaves to improve ventilation.

2. Water at the Base, Not the Leaves

Blight spores spread through water droplets on foliage. Use a soaker hose or water directly at the soil level to keep leaves dry and reduce the risk of infection.

3. Mulch and Rotate Crops

Adding a layer of mulch around your plants helps prevent soil-borne spores from splashing onto leaves. Crop rotation is also crucial—never plant tomatoes in the same spot two years in a row.

4. Pick Off Infected Leaves Immediately

If you spot any suspicious brown spots or yellowing leaves, remove them right away and dispose of them away from your garden (don’t compost blight-infected material!).

5. Choose a Sunny, Well-Drained Location

Tomatoes thrive in full sun, and blight struggles in dry, warm conditions. A bright, breezy spot will naturally help keep your plants healthy.
