How to plant  Sweetbay Magnolia?

Since it costs so much time to plant Sweetbay Magnolia seeds and an added time to pick a perfect candidate from it to your garden, I strongly suggest you plant a potted nursery plant. As it will give you the opportunity to choose in what shape, type (whether as a shrub or tree) you want to plant in your garden well. 

If you wish to plant a potted nursery Sweetbay Magnolia, then pick a dormant one. Because in those plants, the root system is well established. Then, what you will have to do is remove it from the pot and relocate it to your garden. You can easily buy potted Magnolia with all the above attributes and all, from an online store or a local garden in your area.

CAUTION –

The best time to plant a dormant tree is within the Fall-cool climate. This will help the plant root system grow and establish well to tolerate the winter season.

When you are going to plant the Magnolia, dig the hole in a way such that the width is twice the size of the root ball. And the height of the hole should be not deeper than the root ball height.

Caution –

This is because the Sweet Magnolia tree roots are sensitive to the depth they are growing. If the root's depth is too deep, then the plant might grow poorly. Therefore it's essential to keep the top of the root ball close or above the ground level when planting. 

Take out the root ball gently and place it inside the hole smoothly. When you keep the root ball inside the hole, make sure to keep it solid and don’t crumble the root ball while you place it inside.

Now crush the dug-out soil into small parts and use them to refill the rest of the hole back. First, refill for half of the hole and firm it to release the air spots. Then refill again firmly and water well to settle the tree in it. 

Do not use fertilizer until spring comes back. Then yearly use them in the spring season for some years to help the growth of the Sweetbay Magnolia tree.

How to Maintain the Sweetbay Magnolia by cleaning, pruning, and pinching?

Normally a considerable amount of leaves fall in the Falls season, and some during the Sweetbay Magnolia blooming period. Some petals also fall during the bloom. And the fruit cones as well during the ripe time. So there is a need for cleaning the tree around those periods.

When shaping the tree you can prune the unnecessary shooters after the blooming season. Prune or pinch all the dead, disease infected, broken branches all the way to the bottom to help the tree to develop a strong structure.
