Marigold 'Tomato Growing Secret'

Tagetes patula, French Marigold

Canny gardeners have been growing white fly repelling African and French marigolds alongside their tomatoes for decades. But we know that some marigolds make better white fly deterrents than others, and we've discovered the best there is! We're keeping the variety name under wraps, but we're happy to make it available to serious tomato growers. Try it this season alongside greenhouse and outdoor tomatoes – you'll even see your tomato plants grow better and bear more fruit with our marigolds around them.
