Haremints are hardy shrublets that like rocky locales in an arid climate. Below is a general guide for taking care of them outside of their natural habitat based in tender observation and benign neglect. For grow notes on Lagochilus species, visit /species
There are several methods I've tried for for sprouting Lagochilus seeds:
When using GA3, it's important to use a fresh batch and store it in the fridge.
If the seeds are going to germinate, it will usually happen within 4-5 days of sowing or removal from fridge/application of GA3.
Mineral mix, generic cactus/succulent soil, gypsum pellets (50/40/10 for L. inebrians, 30/60/10 for L. platyacanthus, L. platycalyx, L. seravschanicus) in a terracotta or clay pot.
Soil should be on the alkaline side (hence gypsum):
Water when soil is dry or almost dry. Out of species in cultivation, L. inebrians requires the least water and should only be watered when the soil is completely dry. All species respond well to fertilizer:
I use a good quality cactus/succulent fertilizer, like Cactus Store's Super Kabuto.
Humidity should be kept low - standard indoor r/h of 30-50% is fine. Fans set at a low speed help reduce humidity and maintain airflow. If r/h rises above 50% at hot summer temperatures, consider using a dehumidifier, such as a desiccant dehumidifier.
All species need full sun (6+ hours of direct sun).
In nature, most species flower in the fall (August-October). The flowers follow the general sage/mint arrangement and are easy to pollinate by hand with a thin brush.
For living things like plants, death is inevitable.
Common causes of death for Lagochilus: spider mites, high humidity, and overwatering. If the plant is ever growing lanky, it's probably mites. For the treatment of spider mites, I strongly suggest predatory mites. In most cases, they will devour the spider mites after two applications.
