From our perspective, our root system requires space to establish a strong foundation. Please choose a pot that is at least 12 inches in diameter and has ample drainage holes. Stagnant water around our roots is a primary cause of distress, leading to root rot. A terracotta or clay pot is ideal, as it allows the soil to breathe and helps wick away excess moisture. Position us in a location where we can bask in full sunlight for a minimum of 6 to 8 hours daily. We are native to the sunny Mediterranean hillsides and require this intense light to produce the potent aromatic oils we are known for.
We have very specific soil preferences. We thrive in a lean, well-draining growing mix that closely mimics the rocky, slightly alkaline soils of our homeland. A standard potting soil is too moisture-retentive and rich for our liking. Instead, create a blend by mixing two parts of a high-quality potting soil with one part sharp sand or perlite and one part horticultural grit or small gravel. This ensures excellent drainage and prevents our roots from sitting in dampness. A handful of lime or crushed eggshells mixed into the soil can help maintain the slightly alkaline pH we prefer.
Our relationship with water is simple: we prefer to be on the drier side. Before watering, check the soil moisture by inserting your finger about an inch deep. Water thoroughly only when the soil feels completely dry at that depth. It is far better to underwater us than to overwater us. During the hottest weeks of summer, we may need more frequent watering, but always err on the side of caution. As for food, we are not heavy feeders. A single, light application of a balanced, organic fertilizer at the beginning of the growing season is sufficient. Too much fertilizer will promote excessive leafy growth at the expense of the flavor and potency of our essential oils.
To keep us from becoming leggy and woody, regular pruning is not just appreciated—it is essential. Regularly harvesting or pinching off the tips of our stems encourages us to branch out laterally, creating a denser, more productive plant. The most important pruning occurs just as we begin to flower. While our small white flowers are attractive to pollinators, allowing us to bloom signals the end of our primary leaf production phase. By trimming off the flower buds, you redirect our energy back into producing the flavorful leaves you desire.
We are a perennial herb, which means we are built to return year after year. However, in colder USDA zones, our potted existence makes our root system more vulnerable to freezing temperatures. To help us survive the winter, move the container to a protected location, such as an unheated garage or against a sheltered south-facing wall. You can also insulate the pot by wrapping it in burlap or bubble wrap. Our top growth will likely die back, which is a normal part of our dormancy cycle. Water very sparingly during this time, just enough to prevent the soil from turning to dust. With this care, we will gratefully push out new growth when the warmth of spring returns.
