Citronella Plant Care

Planting Citronella

Before planting Citronella, choose a spot in your garden that receives full sun for at least 6 hours a day. The soil must be well-draining and have a pH level between 5.5 and 7.5. Dig a hole twice the size of the root ball and carefully place the plant in it. Fill the hole with soil and gently press to remove any air pockets. Water thoroughly.

Watering and Fertilizing Citronella

Citronella needs regular watering but can tolerate some drought. Water deeply once a week, especially during the dry season. Avoid overwatering as this can cause root rot. Fertilize every two weeks with a balanced fertilizer during the growing season, which is from spring to fall.

Pruning and Disease Control

Pruning Citronella helps to promote bushier growth and increase foliar density. Prune off old leaves and branches to stimulate growth. Pests and diseases such as mealybugs and leaf spot are common in citrus plants. Keep an eye out for any signs of infestation, and treat them immediately with neem oil or insecticidal soap.
