Using Epsom salt for roses has long been a best friend and an excellent supplement for rose growers!
While blooming, rose bushes can suffer from a lack of magnesium causing a magnesium deficiency. Using Epsom salts like this as a fertilizer supplement can solve the problem.
Learn how the master gardener grows happy, healthy and beautiful roses by using simple, inexpensive Epsom salts.
The Benefits Of Epsom Salts For Roses
The chemical makeup of Epsom salts is simple. It is hydrated magnesium sulfate. When diluted with water, all kinds of plants can take up the magnesium quickly and benefit from it greatly.
Here are just a few of the ways magnesium benefits plants in your garden:
- Makes more flavorful tomatoes, veggies, and fruits!
- Supports efficient nutrient uptake
- Increases blooms & fruit
- Speeds plant growth
- Deters pests like snails and slugs
- Improves seed germination and chlorophyll production
While Epsom salts are beneficial, it is always a good idea to test the soil before using it.
Use Epsom salt as a supplement for any lack of magnesium which helps increase fruiting, flowering and boosting plant growth.
Is Epsom Salt Good For Roses?
Serious Rose enthusiasts use Epsom salts to help strengthen their plants. Using Epsom salt helps “build” lush, dark green foliage as a gorgeous backdrop to dazzling, bright, abundant blooms.
The added magnesium levels help increase the production of chlorophyll in the plant for strength and deep, rich color.
Supplementing with Epsom salt will “assist” the slow-release fertilizer and help plants produce more bottom breaks (canes originating at the base of the plant) for dense, lush foliage, increase blossom size and quantity, it’s best when planting to start roses out with a dose of Epsom salts.
Apply Epsom salt as soon as you see new growth and again when they begin to bloom. Follow these instructions for the right application at the right time:
Incorporating Epsom Salt Into Soil
Broadcast it like grass seed at a rate of about a cup per 100 hundred square feet. Work it into the soil very well before planting.
Using Epsom Salt As A Fertilizer For Roses When Planting
Before planting bushes like knockout roses, give the roots a nice soak in a gallon of lukewarm water with a mix of 1/2 cup of Epsom salts.
When planting new bushes, put one tablespoon of Epsom salt at the bottom of the hole. Cover it over with dirt, then place the plant on top.
Adding Epsom Salt To Established Plants
For established roses, add a top dressing to the soil. Sprinkle approximately one tablespoon of Epsom salt per one foot of plant height around the plant.
Water in thoroughly. You can apply top dressing once a month through the entire growing season.
Using Epsom Salt As A Foliar Spray Application
I’m not a fan of applying anymore spray than necessary to roses foliage due to potential powdery mildew… use with caution.
However, generally speaking, I like liquid fertilizer applications. They work best of all the forms of application.
To apply a foliar spray, add one tablespoon of Epsom salt to a gallon of water for each foot of bush height.
Spray the foliage as soon as the leaves begin to open in spring time and once again when your roses start flowering.
Epsom salts have been a real boon to the master gardener for decades and rosarians in particular. It provides tremendous benefits to plants and soil, is safe (when used at the right rate) and amazingly affordable.
It is an all-natural “rose” fertilizer that gardeners of every kind swear by; even though, their claims have never been scientifically proven.
You don’t need to worry about overdoing it with Epsom salts because it is pH neutral.
Generally speaking, you can count on Epsom salts as a quick and easy fix to a wide variety of garden problems, especially magnesium deficiency and a special tonic for your roses.
