One Hundred Dollars a Month reader Claudia recently sent me an email asking how she should take care of a rhododendron shrub her mother in law gave her.
Here in Washington you cannot drive down the street without seeing a giant rhododendron in someones yard. A rhododendron is an evergreen that has beautiful big blooms in the spring. It is very similar to an Azalea {except Azalea’s aren’t evergreens}. They are perfect if you have a shady spot that is in need of some color. {I have plenty of shady spots in my backyard, but Rhododendrons are poisonous to dogs, so sadly, I cannot have them.}
They require just a bit of TLC, but once you get the basics down, they make a great addition to your landscaping.
With Rhododendrons, the first thing to consider is soil. They prefer a slightly acidic soil {kind of like blueberry bushes}. So, some soil amendments might be in order. {I use coffee grounds and pine needles to amend my soil}.
Next, consider placement. They do not like direct sunlight, and can’t withstand a ton of wind. So choose a shady protected area. They are perfect for those shady areas that might be up against the house.
Next, mulch, mulch, mulch. Rhododendrons have shallow roots that need to be protected from weather extremes, both hot and cold. The mulching will help keep the moisture level consistent too–they like that delicate balance of not drying out and not sitting in stagnant water. Mulching with pine needles or pine straw can help with the soil pH and protect the roots.
Finally, make sure to prune your Rhododendron immediately after they finish blooming {usually June-July}. If you wait too long, they get a bit cranky, and may not give you flowers the next year. To prune, just pinch back dead blooms. Over-pruning can also lead to a couple of years of no-blooms. If you have an established Rhododendron that has gotten too big, you may just have to bite the bullet, prune it way back, and accept a couple of years with no flowers. They are grudge holders, but they always come back around, eventually.
Rhododendrons do not really have a ton of insect problems, and with a bit of routine maintenance, they will provide years of year-round color to your yard.
