Typical Growth Conditions for Lomatium foeniculaceum ssp. macdougalii
Lomatium foeniculaceum ssp. macdougalii, commonly known as Macdougal's desertparsley, is a herbaceous perennial plant that is commonly found in the southwestern part of the United States, particularly in Arizona, Utah, Nevada, and New Mexico. The plant prefers to grow in dry and rocky places including canyons, rocky slopes, and mesas.
Light Requirements
Lomatium foeniculaceum ssp. macdougalii requires full sun to partial shade for optimal growth. The plant prefers to grow in areas with high light intensity and does not thrive in areas with low light intensity. Lack of adequate light may lead to stunted growth and reduced flower and seed production.
Temperature Requirements
The plant prefers to grow in warm to hot temperature conditions with a yearly average temperature range of 12°C to 27°C (53.6°F to 80.6°F). Temperatures below 10°C (50°F) may hinder growth and cause the plant to go dormant. The plant can tolerate high temperatures up to 40°C (104°F) and low temperatures down to -12°C (10°F).
Soil Requirements
Lomatium foeniculaceum ssp. macdougalii grows well in well-drained soil that is sandy or rocky in nature. The plant can tolerate soils that are slightly acidic to alkaline with a pH range of 6.0 to 8.0. High soil moisture may lead to root rot, which may cause the plant to die. The plant is adapted to grow in soils that are low in nutrients and organic matter.
Cultivation Methods
Lomatium foeniculaceum (Nutt.) Coult. & Rose ssp. macdougalii (Coult. & Rose) Theobald, also known as Desert Parsley, thrives well in well-draining soil with a pH ranging from 4.5 to 7.5. It requires full sunlight and prefers dry and sandy soil, which is typical of its natural habitat. The plant may be propagated by either seeds or cuttings. The ideal temperature range for successful growth is between 60 and 80°F.
Watering Needs
Desert parsley is drought-tolerant and requires little water for growth. However, newly planted seedlings require regular but light watering. Once established, the plant needs watering only when the soil surface is completely dry. Overwatering can lead to root rot and damage the plant.
Fertilization
Fertilizers may not be necessary for Lomatium foeniculaceum (Nutt.) Coult. & Rose ssp. macdougalii (Coult. & Rose) Theobald. The plant can take up nutrients from the soil and does not need extra fertilization. However, if you want to fertilize the plant to enhance its growth, consider using organic fertilizers that are low in nitrogen.
Pruning
Pruning is not necessary for Lomatium foeniculaceum (Nutt.) Coult. & Rose ssp. macdougalii (Coult. & Rose) Theobald. The plant is naturally bushy and has a neat form. Deadheading can be done to remove spent blooms and stimulate more growth. The plant does not require any other pruning techniques to maintain healthy growth.
Propagation of Lomatium Foeniculaceum ssp. Macdougalii
Lomatium Foeniculaceum ssp. Macdougalii, commonly known as MacDougal's biscuitroot, is a herbaceous perennial plant found in western North America. The plant is propagated through seeds and root cuttings.
Propagation by Seeds
Seeds of Lomatium Foeniculaceum ssp. Macdougalii can be sown in spring or fall directly into the garden bed when the soil temperature is between 10°C to 15°C. The seeds must be sown at a depth of 1/16 to 1/8 inch in well-drained soil. Germination of the seed may take up to 8 weeks, and the seedlings must be kept moist during the germination period.
Propagation by Root Cuttings
The plant can also be propagated by root cuttings taken in the fall season. A 4 to 6-inch long section of the root is cut from the parent plant and buried in the garden bed 2 to 3 inches deep. The soil must be kept moist, and the cutting will start developing a new plant in the next growing season.
Disease Management
Lomatium foeniculaceum ssp. macdougalii is known to be resistant to most plant diseases. However, it may still be impacted by some diseases such as leaf spot and powdery mildew.
Leaf spot can be identified by discolored spots on the leaves which may become necrotic and fall off. Powdery mildew, on the other hand, can be identified by a white powdery substance on the leaves.
To manage leaf spot, remove and destroy infected plant parts or use fungicides. For powdery mildew, improve air circulation and reduce humidity. Fungicides can also be used.
Pest Management
Lomatium foeniculaceum ssp. macdougalii is generally tolerant to most pests. However, there are a few pests that might affect the plant such as aphids and spider mites.
Aphids can be identified by their small size and pear-shaped body. They suck plant sap and can cause distortion and yellowing of leaves. Spider mites, on the other hand, cause dehydration of leaves and dryness.
Management of these pests involves the use of appropriate insecticides or horticultural oils. Regular monitoring of plants for infestation is also necessary for early detection and management.
