How to Grow Patchouli Plants
Patchouli likes a warm, damp climate in fertile, well-draining soil in an area of full to partial sun exposure. This herb is conducive to container growth, or you can plant it directly into the garden. Patchouli herb plant thrives in a soil pH of between 5.5 and 6.2.
Dig a hole matching the depth of the container in which the herb comes in. Place the plant in the hole and tamp the soil down around the herb to eliminate any air pockets. Give the herb 20 inches of room around it to grow into and water it in thoroughly. Thereafter, allow the topsoil to dry before watering. A good layer of mulch around the patchouli herb plant is recommended to retain moisture.
Patchouli Plant Care
Fertilize the herb each spring with an NPK plant food in the amount of 10-10-10 and thereafter once each month until the fall.
Prune any leaves that are dying, diseased or otherwise damaged. Patchouli is susceptible to infection with leaf blight. Prior to pruning the plant, dip the shears in a mix of 70% denatured alcohol and 30% water to retard the spread of the disease.
Caterpillars love patchouli plants as well, so be vigilant about their discovery and removal.
Winter watering should be reduced to allow the plant to go into dormancy. If you grow patchouli plant in containers, they can be moved indoors for protection, especially in areas with harsh winters. First acclimate the plant by setting it in a shady area for a few days prior to bringing it inside; this will keep it from becoming shocked by the sudden temperature shift. Place the container in a south facing window where it can then receive at least 6 hours of sunlight.
