Propagation of Agastache micrantha
Agastache micrantha is commonly known as the southern giant hyssop and belongs to the Lamiaceae family. It is a native wildflower in North America and is often used in ornamental gardening. This plant is drought tolerant and can grow in a variety of soil types.
By Seed
Agastache micrantha can be propagated easily from seeds. The best time to sow the seeds is in the early spring. The seeds should be sown on a well-draining soil mix and covered lightly with soil. The soil should be kept moist until the seeds germinate, which can take up to 2 weeks. Once the seedlings have 2-3 true leaves, they can be transplanted into individual containers or directly in the garden.
By Cuttings
Agastache micrantha can also be propagated from cuttings. The best time to take cuttings is in the early summer when the plant is actively growing. The cuttings should be taken from the tips of the stems and should be about 4-6 inches long. Remove all the leaves from the lower half of the cutting and dip the cut end of the stem in rooting hormone. Plant the cutting in a well-draining soil mix and keep it moist until roots form, usually in about 2-3 weeks.
By Division
Agastache micrantha can also be propagated by dividing the plant. The best time to divide the plant is in the early spring when new growth appears. The plant should be lifted carefully from the ground, and the root ball should be divided into sections with a sharp knife. Each section should have a few stems and a healthy root system. The divided sections can then be replanted immediately in the garden or in individual containers.
Disease and Pest Management for Agastache micrantha
Agastache micrantha, commonly known as mountain hyssop, is a beautiful plant that produces clusters of purple flowers.

However, the plant is susceptible to some diseases and pests that may cause serious damages if left unchecked. Here are some of the common diseases and pests that can affect Agastache micrantha and how to manage them:
Common Diseases
1. Powdery mildew: Powdery mildew is a fungal disease that causes a white or grayish powdery growth on the leaves and stems of the plant. It can result in stunted growth, yellowing of leaves, and reduced flower production. To manage powdery mildew, ensure that the plant receives adequate air circulation and sunlight. Avoid overhead watering and remove any infected plant parts. Additionally, apply a fungicide such as sulfur, potassium bicarbonate, or neem oil to control the disease.
2. Root rot: Root rot is a fungal disease caused by prolonged exposure to wet soil. It can cause the roots to decay, resulting in wilting, yellowing of leaves, and plant death. To manage root rot, ensure that the plant is grown in well-drained soil and avoid over-watering. Additionally, treat the plant with a fungicide containing copper or chlorothalonil to control the disease.
Common Pests
1. Aphids: Aphids are small, pear-shaped insects that feed on the sap of the plant. They can cause stunted growth, yellowing of leaves, and reduced flower production. To manage aphids, spray the plant with a strong jet of water to dislodge them. Alternatively, apply an insecticidal soap or oil to control the pests.
2. Spider mites: Spider mites are tiny pests that suck plant sap, causing yellowing of leaves and webbing on the plant. They thrive in hot and dry conditions. To manage spider mites, increase the humidity around the plant by misting with water. You can also apply a neem oil-based insecticide to control the pests.
In conclusion, Agastache micrantha is prone to some diseases and pests that can affect its growth and health. It is essential to monitor the plant regularly and take prompt action to prevent and manage these problems.
