How to Care for Caryopteris Dark Knight

Be sure to read our planting instructions to ensure a healthy and happy plant for years to come!

Planting Caryopteris Dark Knight Shrubs

We suggest when planting your newly purchased Caryopteris Dark Knight Shrubs 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 backfill soil. We do not recommend using straight topsoil or compost as a backfill soil for Dark Knight 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 of Caryopteris Shrubs 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 too 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.

Watering Caryopteris Dark Knight

After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Caryopteris Dark Knight a good, deep watering. This is not to be rushed. Most of the water you put on the plant at first will run away from the plant until the soil is soaked. A general rule of thumb is to count to 5 for every one gallon of pot size. For example, a one gallon pot would be watered until you count to 5; a three gallon pot would be 15; and so on. Check the plant daily for the first week or so and then every other day there after. Water using the counting method for the first few weeks.
