Monarda can be found naturally along riverbanks and enjoys this rich, organic, moist soil. However, it will grow in average soil as well. Full sun is best, but light shade is tolerated. Plants tend to spread more quickly in the shade, however. Most monardas multiply rapidly either by underground stems or self-sowing. In order to keep plants healthy and vigorous, they should be divided at least every three years in the spring. Deadheading spent blooms will prolong the bloom time. Powdery mildew is a common fungal problem with monarda. Some varieties are more resistant to it than others. To prevent this fungus from appearing, large clumps should be thinned out so that the air circulates freely around them. The soil should also be kept consistantly moist; dry soil promotes powdery mildew.
