Growing Tips, Tricks and FAQs
Growing Tips
Dark Blue Panther catmint is a versatile and low-maintenance perennial that thrives in full sun and well-drained soil. For optimal growth ensure 8-12 hours of sunlight daily. This plant is both drought-tolerant and deer-resistant, making it an excellent choice for various garden settings, including borders, containers, and mass plantings.
When to Grow
Plant Dark Blue Panther catmint in the spring after the last frost, or in the fall for milder climates. It is perennial in USDA zones 4-9, which allows it to thrive in a wide range of environments. Check local frost dates to determine the most optimal time for sowing.
How to Sow and Plant
Start seeds indoors 8-10 weeks before the last frost or sow directly in the garden once the frost danger has passed. Surface sow the seeds or transplant ones you have started indoors in well-draining soil, spacing them about 12-18 inches apart to accommodate their spread. Many people prefer propagating theses plants through cuttings as it is generally easier than growing from seeds. Simply take a cutting from a healthy plant, remove the lower leaves, and place it in water until roots develop. Then, plant it in the soil.
How to Grow
Catmint is relatively easy to care for. Water new plants regularly until they are established, after which they will only need watering during extended dry periods. The plant does not require much fertilization, and overfeeding can lead to leggy growth. Shearing the plants back by one-third after the first bloom encourages a second flush of flowers and keeps the plants looking tidy.
How to Save
Seeds are mature once the flower heads have fully dried and turned brown. To harvest them, cut the flower spikes and place them inside a paper bag. This allows the seeds to completely dry and drop; you may need to shake the bag gently to help loosen the seeds. Afterward, separate any chaff from the seeds and store them in a cool, dry place.
