Planting and Care
Planting your Nightglow® Diervilla is easy:
Dig a hole twice the width of the pot, and deep enough so that when you place the plant in the hole, the top of the root ball is level with the ground around the hole. Fill in the space around the plant with a planting soil mix (you can buy this where you buy the plant) and press the area down with your foot.
Give the plant a good watering to help it settle in.

Your plant needs regular watering to settle into its new home and establish roots. Give your plants a good soaking about once per week, and more often when it’s hot. Keep in mind that plants in containers dry out faster than in the ground. If leaves are wilting or curling, more water is needed. Use a soaker hose or drip system to make watering easier.
Reduce watering and weeding by adding a 2-3 inch layer of organic bark mulch around your plants. You can find this at your local garden center.
Your plant won’t need a lot of fertilizer, but it will benefit from an organic all-purpose fertilizer in the spring when the leaves start to sprout. A fertilizer with a higher middle number (e.g. 15-30-15 or 5-10-5) will work best.
Prune in spring after the threat of frost is over. Trim to a low mounding shape for great form and flower performance.
