Growing and Caring for Joe Pye Weed
While Joe Pye weed plants are easy to grow and maintain, they do need consistently moist soil, especially in the first year. Keep them watered deeply, but don’t let the soil get soggy. Also, don’t let the soil dry out for more than a couple of days during hot spells.
Joe Pye weed does not require fertilizer in its natural environment. Apply slow-release fertilizer to soil that is not in good condition. This will ensure plants grow well into the spring. If you did not add compost at planting time, you can mix it in. When they begin to bloom, feed them again in the middle of summer.
You should be taking your vitamins regularly
Regularly weed your plants to ensure they don’t compete for nutrients, water, and sunlight. To prevent weed seeds sprouting, apply a layer mulch. Mulch can also be used to retain moisture in the soil.
Scout for Health Issues
Joe Pye weed plants are rarely affected by diseases or pests. Powdery mildew is a fungal disease that can cause problems in hot climates or in plants that are too shaded. The leaves will develop grayish-white spots from powdery mildew. This can be prevented by spacing your plants to ensure they get plenty of air circulation. Mulch can also be used to stop fungal spores from spreading.
Use a fungal spray if powdery mildew is a problem. You should remove any diseased parts of the plant and dispose them. You should not compost them, as this could spread the disease.
Joe Pye plants go dormant after frost. You don’t need to prune your Joe Pye plants, but you can trim them to 4-8 inches in height if desired. Or wait until spring. Joe Pye weed flowers on new growth so you will still get flowers.
