Rhododendrons only reach their full height after many years. During that period, a great deal can change, whether in your garden or in terms of your personal taste. Sometimes, a rhododendron will expand so much that transplanting it becomes essential. After five years, this can be done without a problem.
How to transplant a rhododendron
Step 1: Prepare to transplant your rhododendron in autumn
Your shrub is then resting, no longer suffering from the heat and the sun. Start early to allow your plant to settle before the frosty winter period sets in.
Step 2: Dig a new planting hole
Dig a new planting hole that is two to three times the size of the root ball. Do not dig too deeply and be sure to test the pH level in advance, as the soil must be sufficiently acidic.
Step 3: Water thoroughly after transplantation
Watering the rhododendron will help the plant re-establish itself more quickly. No need for additional fertilizer at this stage. The roots will have sustained some damage, but it is best to let them heal naturally.
