Light Requirements
Monardella odoratissima Benth. ssp. pinetorum requires full sun exposure to grow and flourish. This plant cannot tolerate shade, and it requires at least six hours of direct sunlight exposure daily.
Temperature Requirements
The preferred temperature range for Monardella odoratissima Benth. ssp. pinetorum is between 20 to 30 degrees Celsius. This plant can survive in hot weather conditions, but it requires regular watering to keep the soil moist. Low temperatures can be detrimental to this plant, and it is not frost tolerant.
Soil Requirements
The plant prefers well-drained soils with good aeration. The ideal soil should have a pH range of 6.5 to 7.5. It can tolerate various soil types like sandy or rocky soils, as long as they are well-drained. A high-quality organic matter like compost should be added to the soil before planting to enhance the soil's health and fertility.
Cultivation Methods
Monardella odoratissima Benth. ssp. pinetorum (Heller) Epling, commonly known as mountain pennyroyal or coyote mint, is a herbaceous perennial native to California. It prefers well-drained soil and full or partial sun exposure. For cultivation, the plant must be propagated through seeds or cuttings. Seeds must be sown in late winter or early spring, while cuttings must be collected in summer and planted in late summer.
Watering Needs
Mountain pennyroyal plants require moderate watering. The soil must be kept moist during the first year of growth, but not waterlogged. Once the plant has established itself, it can go for long periods without watering, as it is drought-tolerant. It is essential to avoid overwatering the plant as it can result in root rot or other fungal diseases. It is best to water the plant in the morning to prevent waterlogging and to allow the foliage to dry before sunset to avoid mildew.
Fertilization
Mountain pennyroyal does not require frequent fertilization. However, applying a balanced fertilizer during the spring can stimulate plant growth and flowering. To do this, use a slow-release nitrogen fertilizer and follow the instructions on the package for the proper application rate. Over-fertilization may cause the plant to become leggy and reduce the number of flowers. So, it is essential to avoid excessive fertilization.
Pruning
Pruning is not mandatory for mountain pennyroyal. However, it can help to shape the plant and increase its longevity. Prune the plant in the fall to a height of two to three inches above the soil. It will stimulate new growth in spring and rejuvenate the plant. Also, pruning dead or diseased parts of the plant will prevent the spread of diseases to other parts of the plant. When pruning, use a sharp and clean cutting tool to avoid tearing the plant's tissue.
Propagation of Monardella odoratissima Benth. ssp. pinetorum (Heller) Epling
Monardella odoratissima Benth. ssp. pinetorum (Heller) Epling, commonly known as pine-scented monardella, is a hardy plant native to California, USA. It can be propagated through both sexual and asexual methods.
Seed Propagation
The most common method of propagating Monardella odoratissima is through seed propagation. Seeds should be collected in the fall when the seed heads are dry and brown. To sow the seeds, prepare a potting mix of sand and peat moss and sprinkle the seeds over the surface of the mix. Do not cover the seeds with soil as they need light to germinate. Keep the potting mix moist and provide plenty of sunlight.
Germination will occur in 2-4 weeks, and the seedlings can be transplanted into individual pots once they have grown true leaves. Once the seedlings are established, they can be planted in the garden.
Vegetative Propagation
Vegetative propagation of Monardella odoratissima is also possible through stem cuttings or division.
To propagate through stem cuttings, take a 4-6 inch cutting from a healthy plant and remove the lower leaves. Dip the cut end in rooting hormone and plant the cutting in a potting mix of sand and peat moss. Place the pot in a bright location, keep the soil moist, and roots will develop in 4-6 weeks. Once the roots have established, the new plant can be transplanted into the garden.
To propagate through division, dig up an established plant and carefully separate the roots into several small sections. Replant each section in a well-draining soil mixture and keep moist until the plants have established.
