Dolomite lime is a specific type of limestone that can be used to supply necessary nutrients to plants and to raise the pH of the soil. Also referred to as calcium magnesium carbonate, it contains varying amounts of both calcium and magnesium.
Which plants benefit from dolomite lime?
Dolomite (calcium magnesium carbonate): Similar to garden lime but slower acting. Also contains magnesium carbonate so good for trees like apples and pears.
Is dolomite lime harmful to humans?
Safety Precautions

How do you apply dolomite to plants?
If adding dolomite to an existing garden bed, rake aside any existing mulch. Scatter the required amount of the dolomite over the surface of the soil, keeping it several inches from the base of each plant. Work it into the top inch of beds holding deep-rooted shrubs, trees and perennials.
Why is dolomite harmful?
Some dolomite products might be contaminated with heavy metals like aluminum, arsenic, lead, mercury, and nickel. Because of this concern, it might be wise to choose a safer calcium or magnesium supplement. Also, dolomite might cause stomach irritation, constipation, nausea, vomiting, and diarrhea.

Best timing: early spring or late fall. Work the required quantity into the top 15 cm of soil. DO NOT exceed 2 kg per 10m2 per application.
How long does it take dolomite lime to work?
Applied in the same manner as calcitic lime, dolomitic lime takes at least a year before achieving measurable results unless the soil pH is extremely low, when results may be observed within only a few weeks. Several factors affect reactivity time.
Does dolomite raise pH?
Dolomite is added to growing medium to raise pH to the range of 5.5 to 6.5 and to supply plants with calcium and magnesium needed for healthy growth.
Which plants do not like lime?
According to Rural Living Today, several plant species react poorly to lime, such as sweet and regular potatoes, peppers, and tomatoes. Certain types of berries, like strawberries, raspberries, and blueberries, prefer acidic soil, so lime would only take away the elements they need to thrive.
Do roses like dolomite lime?

What happens when lime gets wet?
Lime reacts readily with water to produce slaked lime, which is the chemical compound calcium hydroxide. A considerable amount of heat energy is released during this reaction. Calcium hydroxide is sparingly soluble in water producing an alkaline solution known as limewater.
Is dolomite good for all plants?
Dolomite, a type of limestone, provides valuable nutrients to plants and helps change the pH of the soil by raising it to match the plants’ needs. It’s sometimes called dolomitic lime or dolomitic limestone, and provides more nutrients than straight lime.
Can you use too much dolomite?
It is also possible to use too much dolomite lime. It will cause the same problems as too much ordinary lime. What is this? The soil pH will get too high, the pH may rise too rapidly, and you may end up with excessive amounts of calcium or magnesium in the soil.
How do you use dolomite lime in potted plants?
You also can add dolomitic limestone to the potting mixture at planting time since it contains calcium and magnesium. Apply one tablespoon of lime per gallon of soil mixture. When mixing your own soil for potting, it is best to add a premium grade fertilizer.
