Tomatoes, Fusarium Wilt, and Dandelion, a Virtuous Plant!
Canadian researchers have discovered that the dandelion weed can protect tomato plants from fusarium disease. Fusarium attacks the plant roots. It reduces the number of tomatoes that the plant produces. Dandelion roots produce cichoric acid. This acid prevents the disease from getting iron from the soil. Fusarium needs iron to survive.
Plus, dandelion greens have superior nutritional and medicinal properties, 4 times the Vitamin A in spinach, in fact, the highest of all greens! The cultivated dandelion variety, Taraxacum officinale, is said to be far superior to the rest in taste! It has broad upright leaves that seem to multiply in great stands right before your eyes. These dandelions like rich, moist soil. Commercial varieties include Thick Leaf, Improved Thick Leaf, and Arlington Thick Leaf. Most American dandelion growers cultivate San Pasquale and Catalogn chicories, but call them dandelion greens, which are similar. Oh, and after a frost, their protective bitterness disappears.
Wild Man Steve Brill says: ‘The leaves are more nutritious than anything you can buy. They’re higher in beta-carotene than carrots. The iron and calcium [more than milk!] content is phenomenal, greater than spinach. You also get vitamins B-1, B-2, B-5, B-6, B-12, C, E, P, and D, biotin, inositol, potassium, phosphorus, magnesium, and zinc.’ Low in calories, a terrific liver cleanser, people have eaten dandelions for centuries. The name comes from the French, who called them dent de lion, or “lion’s teeth” because of their sharp, serrated leaves. All parts of the dandelion are edible, but the youngest leaves, less bitter before blooms form, are most commonly eaten, in salads, sautéed or steamed. Drizzle with a deliciously tangy vinaigrette made of honey, Dijon mustard, orange juice, and fresh rosemary. Or toss with garlic, olive oil, and freshly ground black pepper, or with bacon fat (pancetta if you prefer) and a little wine vinegar. Island Seed & Feed has some seeds!
Do know that many weeds, including dandelions and lambsquarters, are known to host verticillium wilt. Remove them when your crops are done. Don’t let them overwinter or leave them lying about.
More Tomato Tips!
Buy toms that are tagged VFN, or just VF – that’s Verticillium Wilt and Fusarium resistant. When they are about a foot tall, water their neighboring plants, but not them. That keeps a drier soil the fungi can’t thrive in. Once a plant has the diseases, the leaves curl lengthwise and black spots appear on the lower stems and leaves, pull it and start over. Months of lost production time and poor production are not worth it. If your plant gets diseased, but is producing and you decide to keep it, don’t prune out the suckers (the little branches that are between the main stalk and a branch) because blight can enter your plant through these cuts. For more pollination, tap your stakes and cages, or the main stalk, to shake the flowers – around 11 AM is best! If your toms aren’t well pollinated, they may be strangely shaped! Plant different kinds of toms apart from each other so 1) they don’t hybridize on the spot 2) the wilts don’t spread from one plant to the next. Since toms are true heat lovers, you can plant a U perimeter of tall plants, leaving the South side open, and plant your toms in the U! Water those neighbor plants, not the toms directly, regularly, so your tomato’s tap root can get regular water. That prevents blossom-end rot.
