The larvae of the artichoke plume moth attack the plant's developing bud, eating through its base and destroying the fruit. Control plume moth larvae with beneficial nematodes or remove infected plants entirely.
Diseases
Prolonged wet weather, combined with warm temperatures, is the perfect breeding ground for Verticillium wilt and Botrytis rot. Symptoms of these diseases include stunted growth, wilting leaves, gray to brown discoloration and smaller bud production. Plant artichokes in well-draining soil in an area with good air circulation to prevent infection.
Soil Moisture
Artichokes are sensitive to too little or too much moisture in the soil. Prolonged periods of drought result in small numbers of tiny, stunted buds with weak stems. Bracts often develop a brown to black discoloration without enough water. When exposed to soggy soils or standing water, artichoke roots suffocate and begin to rot.
Harvest
Timing the harvesting may prove difficult for some varieties of artichokes. The best time to harvest artichoke buds is when their bracts begin to open. In some varieties, the bracts never open, causing either a premature or a delayed harvest.
