Pot Cuban oregano in a 6- to 8-inch pot to allow for sufficient growth and for regular harvesting of leaves. Cuban oregano does well in both clay and cement pots.
Place pots in full sun and water regularly to encourage luscious leaf growth. Cuban oregano does best when the soil is allowed to dry slightly between waterings.
Harvest cuban oregano during midsummer. This is when leaves will be thickest and ready for harvesting. Cuban oregano leaves can grow to be 1/4 inch thick.
Remove the entire leaf from the stalk. The leaves are best used fresh and should be picked right before cooking.
