Homeowner Growing & Maintenance

Agastache is easy to grow, but needs to be planted in locations where it does not stay wet. Feed once a year with a slow release fertilizer. To give your plant the best start possible, we include free fertilizer with every order.

Interesting Notes

Customer Testimonials

You should have the option "EXCELLENT" available as a survey option answer; which I would have selected I have ordered from several national mail-order nurseries before I knew about your Sooner Plant Farm. I have received several gorgeous, healthy plants packaged very well. Glad you are out there, and will order again soon.
