What Is The Best Fertilizer For Magnolia Trees?
Fertilizing a magnolia tree with organic fertilizers will not only increase the size of your magnolia but it will also boost its vigor. Organic fertilizers are those which do not contain any chemicals or synthetic ingredients. They are made from natural sources such as composted animal manure, fruit peels, leaves and other plants. You can buy these fertilizers at most garden centers and home improvement stores.
You may want to consider using a high quality fertilizer when planting a magnolia tree because they tend to grow faster than low grade fertilizers. If you use too much fertilizer, the roots will become overgrown and the tree could die off before reaching maturity. When choosing a fertilizer, look for one that contains nitrogen, phosphorus and potassium. These nutrients are essential for healthy growth of your magnolia tree.
The best fertilizer for magnolia trees is one that contains all three nutrients. Some of the most popular types include:
Organic fertilizer – This type of fertilizer is made from organic materials such as composted animal manure, fruit peels, leaves and other plants. It’s easy to apply and does not require any special equipment. However, some experts say that organic fertilizers have been known to cause problems if used improperly.
Bone meal – This type of fertilizer is made from the bones of cows that have been cooked down until all that’s left is the nutrient rich bone marrow. It is high in phosphorus and nitrogen which are both essential for magnolia tree growth. It is not as readily available as other types of fertilizer and it can be very expensive.
Blood meal – This type of fertilizer is made from dried blood powder that is high in nitrogen, which promotes vegetative growth. It can be used on all types of plants but it should be applied in very small quantities. Some experts believe that blood meal is a possible health risk because it may attract pests such as rats and mice.
Synthetic fertilizer – This type of fertilizer is made from ground up minerals and rocks. They provide nutrients in the most readily accessible form and are very easy to apply. Some of the most common ones include:
Greensand – This type of fertilizer is made from sand and it’s high in potash, which promotes healthy growth of plants. It also contains a small amount of phosphate, which is beneficial for flowers and plants.
Bone meal – This type of fertilizer is made from ground up animal bones and it’s high in phosphorus, which promotes healthy root growth. It is more expensive than other synthetic fertilizers.
How To Plant A Southern Magnolia Tree
You should plant your magnolia tree as soon as you can because they do not do well when they are transplanted. Before planting, check to see if your area suffers from an insect infestation. If it does, you may want to treat the roots of your tree before planting it. To do this, place a small amount of Insectides (a.k.a.
Arsenate of Lead) around the roots of your tree and water it thoroughly. This will poison most of the insects in the soil and give your tree a better chance of survival.
Dig a hole in the ground and place some compost, manure or other organic material in the bottom to improve the soil. Magnolias thrive in soil that is rich in organic material.
Place your tree in the hole and make sure that the rootball is just below the topsoil level.
