The front of my house is very sloped and I am looking to plant some azaleas along the front of the house to prevent erosion. I will be laying mulch as well and wanted to make sure azaleas have a good root system to support the ground. I am a first-time homeowner and could use any advice. If you would recommend another plant, let me know. Thanks.

Welcome to the forum, Al P!! :)

An azaleas root system is very shallow, typically extending only about a foot below the surface. You're going to want something that will anchor itself to the ground with a much deeper root system.


Any recommendations for a better plant is going to depend on your plant hardiness zone. Do you need something to survive a cold winter? Will it need to survive a hot summer? :confused:

If you do not know your zone, it can be found here:

I appreciate the help. It looks like I am in 7a. What plants would be good to plant for this zone to prevent erosion?

Vinca, bishops weed (can get pesky and invasive but sturdy and grows fast), ajuga.
How much sun does your hilly hill get?

It is in direct sunlight for most of the day. No obstructions. If the plant could grow to a height of 4-5 ft it would also be helpful. Check out the picture of the slope. Let me know if anybody has a good suggestion to which plant would help with erosion but be tall enough to level it with the brick portion of the house.

Now that I see a picture, how wide is that area? Most plants that are going to get 5' tall are going to have a wider base. Is there room for a 3-4' wide plant there? Since you want it that tall, are you trying to cover the brick?

I read a bit on landscaping to prevent erosion, and it seems that native plants are the best way to go - the taproots tend to go deeper than cultivated plants. Not only that, but they will be naturally adapted to your soil conditions and rainfall, so less maintenance! (y)

It also seems best to use plants with a deep taproot interspersed with plants that have many shallow roots. As the roots mesh together, the deeper roots with hold down the shallower roots. :DThink of it like nailing a net over it. :LOL:

I'm going to suggest clumps of ornamental grasses, with a low groundcover between them.
