Latin name:Tagetes patula
This is one of the most popular massed-colour plants, producing dazzling sheets of bright gold, single flowers over a long season. Additionally, nematodes are one of the most serious of all soil pests, often destroying whole crops. Based on Dutch research, this amazing plant also has the most potent nematicidal effect of all marigolds. Nematodes (Pratylenchus penetrans, P. neglectus, P. crenatus) have serious negative effect on crops of carrots, lettuce, endive, leek and strawberries. Also flower bulbs such as liliums, daffodils, gladioli, hyacinths, irises and tulips can suffer problems of root nematodes. Companion planting tagetes 'Ground Control', which grows particularly well on sandy soil where nematodes are most prevalent, will give you the double advantage of both a beautiful garden and pest-free soil.
