Aruncus Dioicus

After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Aruncus dioicus 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. as mentioned earlier Goatsbeard does not like to dry out during drought so make sure to provide enough water.

Feeding your plants is probably the single most forgotten part of growing healthy long lasting plants. We recommend feeding your Aruncus dioicus in the very early spring and again in mid summer after all new growth has hardened off and it begins to set flower buds. Bio-tone starter fertilizer is the best product to use at the time of planting. Our ideal fertilizer schedule for you to use is as follows. Apply an early spring fertilizer with a product such as Espoma Plant-tone at the recommended rate this will give the plant a boost of nitrogen potash that will be needed for healthy foliage and stem growth. Follow this up with another early summer application of Espoma Flower-Tone, this will again provide the necessary nutrients to promote a flush of beautiful flowers. Espoma products are easy to use, just sprinkle around the base of the plant and water it in. Be careful with products such as miracle-grow as these products can burn newly planted plants when not used at the recommended rates. Slow-release fertilizer can help prevent rapid soft growth that is vulnerable to diseases and insects.

We highly recommend that you mulch your Aruncus dioicus with either a ground hardwood mulch or a ground cypress mulch depending on your local availability. Any type of mulch will do but cypress or hardwood mulch will be of a higher quality and provide better nutrition overall as they breakdown. Mulching helps to keep weeds away which will compete with your new investment for water and nutrients. A 2 to 3 inch layer of mulch is sufficient but remember to take care not to cover any part of the stem of the plant with mulch. Its better to leave a one inch gap of space between the mulch and the stem or base of the plant.

Remove the old flowers of Aruncus dioicus as they become brown and unattractive but this is not necessary as the dried plumes provide added interest in the landscape. They can be cut and brought into the house and used in arrangements. This procedure, called deadheading, encourages the Aruncus plant to produce new foliage, keeping your plant looking attractive throughout the season. Prune the central stems of the aruncus if they begin to die back.
