On young rabbiteye blueberry plants, the most common symptom of a magnesium deficiency is mature leaves that are pink on the edges and yellowish between the veins. When magnesium is low, based on a soil test, you can add Epsom salts (magnesium sulfate) at the rate of 3 ounces per plant to compensate for the deficiency.
Ammonium sulfate is the most commonly recommended blueberry fertilizer for ensuring the pH of the soil remains acidic. How much to initially apply depends, of course, on how acidic your soil is to begin with. Typically, 2 to 4 ounces per bush per year is adequate to maintain an established pH between 4.5 and 5.1.
How do you add Epsom salt to blueberries? You can use Epsom salt if your blueberries need magnesium. You should add one tablespoon of Epsom salts and one tablespoon of apple cider vinegar to two gallons of water and apply to the base of the blueberry plants.
If your blueberries need magnesium, Epsom salt grants temporary relief. In deficient soils, broadcast 1/4 cup of Epsom salt in a 10-inch diameter around the plant, and water thoroughly. If high pH is the real culprit, extra magnesium in the soil won't help, and Epsom salt's sulfur doesn't affect pH.
Natural Fertilizer for Blueberries
For organic fertilizers for blueberries, you can use blood meal or fish meal to provide nitrogen. Sphagnum peat or coffee grounds will help to provide acidity. Bone meal and powdered seaweed used to fertilize blueberries can provide the potassium and phosphorus.
Yes it's perfectly safe to use both Seasol and PowerFeed products on your fruit trees whilst they are in blossom. Make sure to not spray it directly onto the blossoms as it may discolour the flowers.

Carnivorous plants — Pitcher plants, venus flytraps, and sundews are some insect-eating plants that should not be applied with Epsom salts. Because they are adapted to grow in mineral-poor and depleted soil, supplementing fertilizers with even a tiny dosage could mean death to the bug-trapping ornamentals.
People sometimes soak their bodies in Epsom salt baths or drink Epsom salt after dissolving it in a glass of water. However, some people should not consume Epsom salt at all. These include those with kidney disease or heart disease, pregnant women, and children.
Adding Epsom salt is a simple way to increase the health of their blooms, and is something that you can include easily as a part of a normal routine. For potted plants, simply dissolve two tablespoons of Epsom salt per gallon of water, and substitute this solution for normal watering once a month.
Adding Epsom salts to soil that already has sufficient magnesium can actually harm your soil and plants, such as by inhibiting calcium uptake. Spraying Epsom salt solutions on plant leaves can cause leaf scorch. Excess magnesium can increase mineral contamination in water that percolates through soil.
Annual pruning keeps blueberries productive and encourages fresh, vibrant growth for the following year. Prune bushes in late winter, while blueberries are dormant and their large buds stand out. Prune about 1/4 inch above healthy buds, using sharp bypass pruners for crisp, angled cuts.
Yates Dynamic Lifter Soil Improver & Plant Fertiliser is suitable for fertilising potted blueberry bushes. The pellets can be applied every 6-8 weeks.
Blueberries respond well to small amounts of fertilizer applied at three separate applications, the first applied when new growth begins in spring, followed by a second application six weeks later. A third application is made just after harvest.
Since blueberries thrive in low soil pH (4.5 – 5.5), it is recommended to choose an acidic, water-soluble fertilizer, similar to what you would feed Azaleas and Rhododendrons like Jack's Classic® Acid Special with 17-6-6 formulation, or you can utilize Espoma® organic Holly-tone® with 4-3-4 formulation that also ...
Primarily, roses, tomatoes, and peppers are the key plants that can take advantage of the magnesium levels contained in Epsom salts.
Summary. Epsom salt is a popular DIY fertilizer for outdoor and indoor plants. And while it has been shown to boost the magnesium and sulfur content of soil, horticulture experts say it should only be used on plants with known deficiencies in those nutrients.
Blueberries like a soil that is high in organic matter. They also tend to prefer a light soil. For these reasons, I add 40% peat moss and 10% compost, then the remaining native soil should make up the last 50%.
Mattson – who adds Epsom salt to his fertilizer for plants such as roses, pansies, petunias and impatiens – says gardeners can proactively mix Epsom salt with fertilizer and add it to their soil monthly, or they can mix one tablespoon with a gallon of water and spray leaves directly every two weeks.
Is Blood and Bone Good for Blueberries? Bone meal and blood meal are both solid blueberry fertilizers since they are both high in nitrogen. Fish bone meal in particular is helpful to blueberry growth.
Blueberry plants require at least one inch of water per week (65 gals./100 sq. ft.). You must supplement rainfall when necessary. Overhead (sprinkler) irrigation can be used on blueberries, but trickle or drip irrigation is preferred because it conserves moisture and does not wet the foliage.
If you are wanting more acid for azaleas, blueberries, rhododendrons and evergreens, use fresh coffee grounds, as used grounds have pretty much a neutral pH.
At a minimum, you should be fertilizing once a year. In general, blueberry bushes respond best if fed in one to two applications. The second application is only needed for new plants under two years old. The first application in early spring, around early March or April, is the most important to your summer harvest.
