Korean Spice

Common Names: Korean Spice, Viburnum, fragrant, dwarf
Latin Name: Viburnum carlesii 'Compactum'

Blooms in April.
Flowers start as pink buds and change to white blooms.
Has berries in the fall (if pollinated though, not self pollinated). Berries are insignificant and nothing special. It is very difficult to get berries.
One problem you may experience in caring for this bush is leaf curl (at the tips of branches). The culprit will most likely be aphids. If you can manage to catch the little buggers in action, you can spray them with the organic herbicide Neem oil. But aphids can come and go very quickly, leaving a damaged leaf behind. Luckily, leaf curl, if restricted to just a relatively small portion of the entire plant, does no long-term harm. It is problematic only on an aesthetic level, marring the appearance of the foliage during that summer and fall. Prune off the affected branch tips and dispose of them properly, and the plant will be none the worse for it.
Very aromatic.

Didn't find much info for fertilizer, but this for viburnums in general: Viburnums appreciate an annual application of a balanced fertilizer in spring. A balanced fertilizer has an equal ratio of nitrogen, phosphorus and potassium, which should read 10-10-10 on the label. The nitrogen helps viburnums grow lush foliage, while the phosphorus encourages healthy root, stem, flower and fruit growth. Potassium helps viburnums and other plants absorb those nutrients. If using granular fertilizer, sprinkle the granules on the dirt above the roots, then water to flush the fertilizer through the soil.

Prune immediately after flowering since flower buds form in summer for the following year.
Just cut the tips to promote branching and a bushier look. In addition, remove any dead branches and/or branches rubbing against each other.
