Agastache should be planted in full sun and slightly alkaline soil. The most critical factor is good drainage. This plant will NOT tolerate wet soil, especially in winter. When planting, put a thick layer of gravel in the bottom of the hole and then mix more in with the filler soil. Native to the southwest US and Mexico, it is naturally heat and drought tolerant.

Moisture:

Moderate. Provide consistent moisture, but avoid overwatering.

Planting Level:

Crown should be planted even with soil line.

PGRs/Pinching:

Pinching is beneficial to promote lateral branching. PGRs can be beneficial in controlling plant size but may require multiple applications. Daminozide (B-Nine, Dazide) at 2,500-5,000 ppm, Daminozide at 2,500-5,000 ppm + Chlormequat Chloride (Cycocel) at 1,000-1,500 ppm, Paclobutrazol (Bonzi) at 30-60 ppm, or Uniconazole (Concise, Sumagic) at 5-10 ppm.

Lighting:

High light levels, long day obligate.
