How Do You Prevent Wilting in Broccoli Plants? Treating bacterium or root rot nematodes is not feasible once the broccoli plant wilts and falls over. If it is a virus, the plant will not recover and should be removed and placed in a trash bag, then discarded in the trash. If you catch the problem early, they may survive. Plants with fungal infections can be treated with a copper or sulfur fungicide. If overwatering is the culprit, letting the soil dry out before watering again will help. If the broccoli plant is wilted from too little water, you can water the plant and it will usually recover. In most cases, once the plant has wilted and fallen over, reviving the plant is hard. How Do You Revive a Wilted Broccoli Plant? It doesn’t take much for them to wilt and fall over. What Stages of Growth Is Broccoli Most Likely to Wilt and Fall Over?īroccoli is most likely to wilt and fall over during the early stages of growth. Seedlings need more water than older plants because the roots are not as established. This is especially true in young plants or in hot weather. Wilted broccoli plants may mean you need to water more. Overwatering also causes the roots to rot. When the roots are underwater for a long time, they cannot absorb the oxygen the plant needs, and the plant wilts and dies. Roots take in oxygen as well as water and nutrients. We associate wilting with underwatering, but overwatering can cause it too. The entire root swells instead of just having galls on it. Club root Plasmodiophora brassicaeĬlub root is a fungal problem that looks very much like root-knot nematodes. The plant does not grow properly and wilts during the day, recovering at night.Įventually, the roots have so many galls they cannot give the plant enough water and nutrients, so it wilts and dies. Root-knot nematode Meloidogyne spp.Ī very small wormlike creature, root-knot nematodes gnaw into roots, causing galls on them. This often kills a whole tray of seedlings being grown for later transplant. Close inspection shows the stem rotted at the soil line. Damping-off Pythium spp.ĭamping-off is caused by a fungus. The seedling may stay upright, but the stem is constricted, and it cannot grow properly. This virus causes black-red or black rot on seedlings after germination. It causes yellow leaves, wilting, stunting, twisted stems, and causes the death of seedlings. The fungus enters through young roots or wounds in older roots. This used to be a common disease, but most hybrids sold now are resistant to it. Fusarium yellows Fusarium oxysporum forma specialis conglutinans The black spots grow and girdle the stem, causing the plant to wilt and die. Black leg Phoma lingamīlack leg is a fungus that causes ash grey spots on the leaves and stems. The bacterium prevents water and nutrients from going from the roots to the rest of the plant. When the stem is cut open, black-brown color with yellow slime. Once it reaches the veins, it goes into the stems. Yellow V-shaped lesions start at the leaf tips and work towards the veins on the leaf. Black rot Xanthomonas campestris pathovar campestrisīlack rot is a bacterium that also starts in the leaves. The fungus then infects the inside of the stem, preventing water and nutrients from flowing to the leaves and head. Often attacking leaves first with whitish-grey lesions, white mold is actually a fungus. Sclerotinia stem rot (White mold) Sclerotinia sclerotiorum While there are many problems that cause broccoli plants to wilt and fall over, the ten most common are discussed here.
