How to plant
Anise Hyssop can be grown outdoors in the garden or in containers. When planting in the ground, it is important to choose a location that has full sun to partial shade and well-draining soil. If planting in containers, it is important to make sure the pots have drainage holes. The soil should be kept moist but not soggy, and a light fertilizer may be used to promote healthy growth. When growing Anise Hyssop in containers indoors, it is important to remember to move it outside occasionally to get plenty of sun. Anise Hyssop thrives in temperatures between 65-75 degrees F. (18-24 degrees C).
How to pot and repot
When potting Anise Hyssop, choose a pot with good drainage holes and use a well-draining potting mix. To ensure good drainage, use a potting mix that contains a combination of peat moss, compost, and perlite. Make sure the pot is about twice the size that the plant currently is and make sure it is heavy enough that when you water the pot does not tip over. When repotting Anise Hyssop, it is best to do it when the plant is actively growing. Go up one pot size each time and make sure the new pot is clean and has been soaked in a dilute bleach solution before use.
How to prune
Anise Hyssop can be pruned in the early spring and late fall. For best results, prune the plant back to two to three inches above the soil line, or up to one foot if the plant is older. This will encourage the plant to produce bushy growth and new shoots. When pruning in the fall, it is best to leave some of the stems and foliage in order to provide protection from the cold winter months.
How to propagate
Anise Hyssop can be propagated through seed, division, and semi-hardwood cuttings. Seed propagation is done by harvesting the seeds from the plant at the end of the season and planting them in the early spring. Division is done by cutting the root ball into sections and repotting into new containers. For semi-hardwood cuttings, which is the easiest and most successful method, it is best to take the cutting in early summer when they are young and flexible, and root them in a mix of perlite and peat moss. Once the cuttings are planted and soil is lightly pressed in around them, they should be kept moist and lightly shaded.
Common pests and diseases
Anise Hyssop is subject to several diseases and pests, some of which can cause serious damage to the plant. Common diseases include powdery mildew, root rot, crown rot, and Verticillium wilt, all of which can cause foliage spots, yellowing leaves, and wilting. Common pests include aphids, snails, slugs, and spider mites, which can cause plant stunting, discoloration, and defoliation. To prevent disease and pest damage, it is important to practice good sanitation and provide plenty of air circulation. Always clean up leaves and debris that may have fallen around the plant and avoid planting in low-lying or poorly draining areas.
