![]() ![]() ![]() Above ground, small patches of plants will suddenly look wilted, yellow, and stunted.Īnother possible cause could be plain old soil compaction. Club root ( Plasmodiophora brassicae) is an aggressive and persistent soilborne disease that causes their roots to swell and mutate into “club” shapes. If a random patch of cabbage plants looks unusually stunted or mangled, they may be getting attacked at the root. Stunted Plants With Rotten Roots This fungus infects cabbage, causing the plant to look stunted and the roots to become club-shaped. Apply a diluted neem spray or natural copper fungicide to prevent further spread. If you already notice an infestation on your cabbage crop, remove infected leaves or whole plants as necessary. Widen the spacing between the plants to 16-18” to maintain adequate airflow. The next preventative step would be sourcing disease-resistant varieties like ‘Famosa’, ‘Deadon’, and ‘Melissa’. The Brassica family is very prone to foliar diseases like that overwinter on the dead leaves just like downy mildew. How to Fix ItĪny time you’re growing cole crops like cabbage, it’s best to clear away any old plant debris at the end of every season. This disease is particularly problematic in areas with wet, mild winters such as the Pacific Northwest and the Southeast. In high humidity, the fungus produces a fluffy white-grayish mycelium on the underside of the leaf spots. It begins as light yellow-green lesions on the leaf surfaces, which later enlarge and take over whole leaves. Fluffy Gray Growth on Pale Leaves This fungus appears as yellow-green spots on the surface of the leaves.ĭowny mildew is a nasty fungus-like organism that overwinters in infected plant residues and spreads via seeds or spores in the wind. It can handle colder temperatures but tends to form the best heads in a moderate chill. Try to start growing in the spring or fall when temperatures are between 50° and 75☏. Cabbage is particularly temperamental in the summer heat. Temperature fluctuations can also prevent from heading up. You should check the beds every other day to ensure that the soil is neither soggy nor dry. However, avoid excess mulch near the base of they plants if you have a slug problem. Then, mulch on top of your garden beds with compost or chipped dry leaves to help conserve moisture. Use drip irrigation or soaker hoses to deliver water right to the root zone of the plant. Dry soil causes drought stress and soggy soil can lead to disease.īoth overwatering and underwatering can lead to “headless” cabbages, so it is essential to strike a balance between the two and pay attention to your garden beds. The crop itself is over 90% water and requires consistent irrigation to properly grow and produce a head. Just like carrots or radishes, cabbage can’t handle big fluctuations in soil moisture. The main cause of this problem is improper watering. The plants seem to keep putting out leaves without a central ball of cabbage. The biggest complaint cabbage growers have is plants that won’t “head up”. ![]() 13 Dead Lower Leaves With V-shaped LesionsĬabbage Won’t Form a Head Improper watering is the main reason why cabbage does not form a head.Water deep and do not let the soil dry out.Īpply a couple inches of mulch around cabbage to help soil from drying out.įrom seed to harvest cabbage takes 60 days to 75 days depending on the variety chosen. Water Requirements: Cabbage likes moist soil. Cabbage is a heavy feeder and can benefit from compost being added to the soil. Soil Requirements: Prefers fertile well-drained soil. Light Requirements: Cabbage like most vegetables requires full sun or about 6 – 8 hours of sun a day. They like to be near onions, rosemary, dill, thyme, peppermint and sage.Ĭabbage doesn’t like to be planted near beans, strawberries, or tomatoes. ![]() Plant Cabbage Companion Plants for CabbageĬabbage does well when planted near aromatic plants. Seedlings will emerge within a few weeks. If planting by seed they only need about 1/4 inch of soil on top. Allow two feet of space between cabbage plants. Transplants can be planted in the months of January, February and October.Ĭabbage can need a spread up to 12 inches and grow up to 18 inches in height. Plant seeds indoors in the month of September or December.
