Box and Ship Program

Armstrong Growers San Marcos is home to our box and ship program. We have partnered with two reliable consolidators who have proven success with shipping live goods to cities beyond California, Nevada, Utah and Arizona. Your order is expedited and the plants are shipped in a controlled environment to ensure they arrive fresh and ready for their final destination! All plants come sleeved with a retail-ready tag that includes care instructions. Pre-pricing for retail is available for a small fee.
