Getting the Planting Site Ready

Clear your planting site of weeds, rocks and other debris and rake the top few inches of soil to loosen and level it. Make sure your site gets full to part sun (part sun is best if you get hot afternoon sun).

Add Organic Matter

When Does Joe Pye Weed Grow Best?

This herbaceous perennial needs plenty of space and is best planted in the spring, after all chance of frost has passed. It will grow and spread quickly.

Should I Start Joe Pye Indoors?

Although it’s easier to grow Joe Pye weed from plants than seeds, you can start the seeds indoors. They germinate better if they first undergo scarification — a kind of cold treatment. Start eight to 10 weeks before your last spring frost by putting enough water into a bag of soilless seed starting medium to dampen it. Then put the dampened medium into pots and sow the Joe Pye weed seeds on top of it. Lightly press them down but don’t cover them.

Put the pots in plastic bags and place them in the refrigerator for four weeks. Take them out, remove the bags, place the pots by a sunny window or under grow lights, and keep the medium damp. The seeds may take up to four weeks to sprout.

When the seedlings are two inches tall, harden them off by moving them outdoors for a short time each day for about one week. Gradually increase the time they stay outdoors each day until you’re ready to plant them in the garden.

Planting Joe Pye Weed in the Garden

To sow Joe Pye weed seeds directly outdoors, start them in the fall so the colder weather and winter rains can help them germinate. They need light, so gently press or rake them into the soil but don’t cover them. When the seedlings are up, thin them as needed.

For Joe Pye weed plants, dig holes a little larger than the root balls. Put the plants in the holes so the top of each root ball is level with the soil. Space them as indicated on their tags or labels. Backfill the holes and water deeply.

Growing and Caring for Joe Pye Weed

Water Consistently

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.

Fertilize

In its native environment, Joe Pye weed doesn’t need fertilizer. If you have poor soil, apply a slow-release fertilizer according to the directions on your product when the plants show new spring growth. You can also mix in some compost if you didn’t add any at planting time. Feed the plants again in midsummer when they start to bloom.

Weed Regularly

Weed your plants regularly so they won’t have to compete for water, nutrients and sunlight. Use a layer of mulch and reapply it as needed to help prevent weed seeds from sprouting and taking over. Mulch will also help hold moisture in the soil.

Scout for Health Issues

Joe Pye weed plants are seldom affected by pests or diseases. However, powdery mildew, a fungal disease, can be a problem in hot weather or if the plants are in too much shade. Powdery mildew shows up as grayish-white areas on the plants’ leaves. To help prevent this, space your plants so they have plenty of good air circulation and use mulch to keep fungal spores in the soil from spreading.

If the powdery mildew becomes a serious problem, use a fungal spray. Remove any diseased plant parts and discard them. Don’t compost them as doing so could allow the disease to spread.

At frost, Joe Pye plants start to die and go dormant. Pruning isn’t necessary, but if desired, you can cut your plants back to four to eight inches tall at that time or wait until spring. Joe Pye weed blooms on new growth, so you’ll still get flowers.

Joe Pye weed plants are seldom eaten by deer and rabbits.
