Oregano is very drought tolerant. Water once a week.
Oregano shouldn't be fertilized. Fertilizer weakens the flavor of the leaves.
Oregano will continue to produce new shoots throughout the growing season. Be sure to remove any flower buds to encourage leaf production.
Begin harvesting oregano when plants are a 6" tall. Harvest oregano in the early morning for most intense flavor. Cut oregano springs just above the lowest set of leaves, beginning with outer sprigs. Dried oregano leaves have stronger flavor than fresh.
Root Rot: Plant will yellow and wither from this condition. Root rot is caused by over watering or poor drainage. Make sure plants are placed in well-drained soil and understand the watering needs of specific plants.
Spider Mites: Tiny cousins of spider and scorpions, spider mites may appear red to brown or yellow to green. Spider mites damage leaf cells as they suck moisture from them. Plants infested by spider mites may have brown or tan speckled leaves. Ladybugs are a natural predator of spider mites. Sharp blasts of water from a hose can dislodge spider mites and insecticidal soaps can be effective as well.
Aphids: Small, soft-bodied insects that suck moisture from plants. Ladybugs are a great way to control aphids. Consider insecticidal soaps as an alternative to pesticides.
Oregano is a perennial plant. Mulch oregano plants to over winter, and remove any dead stems in the early spring. Oregano plants should be replaced when they become woody, usually after about three or four years.
Division is the best way to propagate oregano plants. In mid spring, dig up oregano plants and clear dirt away from roots. Divide your oregano plant into three or four sections; making sure each section has roots and foliage. Replant each section 10" to 12" apart.
