If you notice a bush blooming now with bright lavender-purple blooms it is most likely a rhododendron. Even though blooms only last 1-2 weeks, these early spring bloomers add a touch of spring delight as we wait for the other spring bloomers to emerge.

Two varieties of rhododendron do well here in North Iowa. They are PJM and Ramapo. PJM’s grow 3-5 feet tall, Ramapo’s grow 2-3’.

Another characteristic of rhododendrons is that they have “broad” leaves that do not drop in the fall. Leaves hold on and turn a mahogany brown/green during winter.

The ideal location for rhododendrons is on an east or north side of a building where it is more shaded from bright afternoon winter sun that can winter burn the broad leaves. However, this year we have noticed rhododendrons thriving on the south and west sides, and even in the middle of yards where there is no protection.

Care for rhododendrons is relatively easy. Water twice a week the first season. After the first season, water once a week if rain is inadequate. Fertilize with “Miracid” fertilizer 2 or 3 times in early and mid-summer. Trim or shape bushes early summer after blooming. (Blooms set on plants in the late summer and fall – so late trimming will simply trim off next spring’s blooms.)
