Warm Weather Patchouli Herbs
Patchouli herbs are warm weather perennial herbs, native to the Philippines and Malaysia. The leaves of the plants are harvested for their sweet smelling oil, traditionally used for medicinal purposes. Patchouli herbs thrives in well-drained soil. The plant thrives in full sunlight but tolerates partial shade. As a tender perennial, patchouli is damaged by cold temperatures. Move the plant to a pot and bring it indoors when temperatures drop to 65 degrees Fahrenheit. Patchouli prefers regular irrigation but not soggy, waterlogged soil. Water the plant once every week that the plant receives no natural rainfall, providing enough water to soak the soil to a depth of about 8 inches. Patchouli herbs grown in a container requires more frequent irrigation, as containerized soil dries quickly. Check the container daily, especially during warm, dry weather. Water deeply whenever the top 1/2 inch of soil feels dry.
Like most herbs, patchouli is a light feeder that is damaged by too much fertilizer. During the growing season, the plant benefits from application of a general-purpose, water-soluble fertilizer once every six weeks. Use a weak solution mixed at half the strength recommended on the label. For patchouli planted in a container, the frequency of fertilization is increased to once every three to four weeks. Patchouli requires no feeding during the fall and winter.
