Secondly, select cultivars that are resistant to disease and situate them on high ground to prevent . Plant only those cultivars that thrive in wet environments and avoid those that are native to drier regions.

Disease spreads easily from plant to plant when leaves are wet, so avoid pruning or harvesting until the foliage has dried off. Prune and stake the plants to improve aeration and increase dry time after heavy rainfall or dewy mornings.if it is lacking and plant in or .

Remove any infected plant parts as soon as you see them. Remember to sanitize the pruners before moving on to other plants so you don’t spread the disease. Then either or burn infected leaves and other plant parts.
