The Rhododendrons are coming into bloom!

Spring is bursting into bloom and the most floriferous plants here in greater Vancouver are the Rhododendrons. There are hundreds of varieties available in a range of colours from white to purple, red to yellow. As you walk or drive around the Vancouver Lower Mainland, you see these everywhere. One of the first to bloom is Rhododendron ‘PJM’. This beautiful purple variety will light up a dark corner of your garden. It will grow 4 to 6 feet tall, they like acidic soil.

For healthy vigorous blooms, they should be fertilized regularly with our Evergro Rhododendron and Azalea Fertilizer (10-8-12). The first application of fertilizer should be made in March or April before they begin to bloom. A second application should be made sometime in June or July after they have finished blooming. This second application is made so that they can develop blooms for the following year.

Rhododendrons need to be planted in an area where there is lots of humus or good workable soil. They have a very fine shallow root system, so they do not do well in heavy clay or very rocky soils. The shallow roots also mean that they do not like cultivation of the soil at their base. Manure, compost, or peat moss makes for excellent soil conditions for their roots.
