Back in the 1960s certain scents were very popular, and one of them was patchouli oil. From patchouli scented shampoo to fragrant essential oil perfumes, the smell of patchouli was everywhere. Today, patchouli, a shrub with small white flowers, is still an important component of cosmetics, and the main reason for which it is grown. It's not an easy plant to grow, especially outdoors, as it won't tolerate cold temperatures. Growing it in pots, indoors, is the most likely scenario for success.
Give your patchouli plant dappled shade, no direct sun, and light, nutrient-rich soil. It requires warm temperatures, ideally between 75 and 80 degrees F. Temperatures under 50 degrees F will most likely kill the plant.
Patchouli plants have very specific watering needs; both too much and not enough water can be deadly. When you do water the plant, water it well, until the water drains out of the bottom of the pot. Then don't water it again until the first inch of soil is dry.
Spray your patchouli plant frequently with a fine mist of water.
Fertilize the patchouli plant by applying a balanced fertilizer, such as 10-10-10, bi-monthly.
Prune the patchouli plant to encourage it to grow bushier. Pruning the longer, leggier branches or shoots will also make the plant look more attractive.
