How to Care for Amsonia Hubrichtii
We suggest when planting your newly purchased Amsonia hubrichtii plants that you dig a hole twice as wide as the root system but not deeper. Depending on the quality of your existing soil you may need to add a locally sourced compost or topsoil to the back-fill soil. We do not recommend using straight topsoil or compost as a back-fill soil because more times than not these products will retain entirely to much moisture and will cause the root system to rot. Adding compost or topsoil will help the young feeder roots to spread through the loose, nutrient rich soil, much easier than if you used solely the existing soil which more times than not will be hard and compacted. The most common cause of plant death after transplanting is planting the new plant to deep. That is why we do not recommend planting in a hole any deeper than the soil line of the plant in the pot. A good rule is that you should still be able to see the soil the plant was grown in after back-filling the hole. Amsonia hubrichtii does prefer drier soils in the winter so if there was ever a plant that we would recommend not adding topsoil or compost this is one. Bio-tone starter fertilizer is a great starter fertilizer that provides plants with mycorrhizae fungus.
