What’s so good about grafted veg plants?  Grafting onto specific rootstocks, of course, creates bigger, better, more disease-resistant plants with increased yield. Consequently, we believe, the extra vigour which the plant obtains will provide even better protection to late Blight attack, and the plants will grow away from any infection even more rapidly. Grow in the greenhouse or outdoors, little or no heating required. With excellent resistance to soil-borne pest and diseases - No more ring culture or grow bags you simply plant straight in the soil.
