Magnolia Trees differ a lot according to size, so the good choice depends mostly on what your garden can handle. The typical southern Magnolia Tree grows around 60 to 80 feet tall, with spread reaching 30 to 40 feet wide. It is truly impressive, too big a tree for most home areas.
Those evergreens need much Space. They impress even more because of their thick leathery leaves that stretch around 10 inches, together with flowers that reach a size of 12 inches across.
Magnolia Tree Sizes and Space Needs
If you like the classical southern Magnolia Tree look, but lack the ground for a 60-foot monster, there are smaller types that deserve attention. The Little Gem Magnolia Tree is simply the little cousin of the southern species. It reaches at most 20 to 25 feet in height and 10 to 15 feet wide, much more fit for current gardens with limited area.
There is also the Teddy Bear Magnolia Tree, another small type, that stays only 5 feet broad, and some stores say that it does not pass 6 to 7 feet tall.
The stellar Magnolia Tree comes from Japan and works for growing zones 4 through 8. That leafy species reaches around 10 to 15 feet tall with spread up to 20 feet, what makes it great for gardeners with limited surface who still want the Magnolia Tree charm. The Jane Magnolia Tree is even more modest, it reaches only 10 too 15 feet tall.
However, the Sweetbay Magnolia Tree needs more Space.
When you plant one sample, give it around 13 to 26 feet of wide area. Smaller leafy species, used as fences, work well if spaced in 10 to 20 feet between them. For standalone trees in bright places, leave at least 40 feet or more, to create the perfect display.
If you form a fence from Magnolia Trees, keep at least 15 feet between them, so that they donot crowd each other.
Plant a Magnolia Tree too near the house can cause problems, because evergreen species do not drop leaves in winter, which blocks the sunshine. Their dense canopy shades everything below, and they have shallow, spreading roots, that can dig into everything around. Those trees like a bit sour ground, that drains well.
Sandy or too clay soil simply does not work.
Magnolia Trees flower best in sunny places. For new planted trees to start well, avoid packing of the soil around the roots and keep foot traffic away from the base if possible. Pruning should be minimal and done only when needed.
The advantage of Magnolia Trees is that all Space sizes present something, from little dwarves to giants passing 100 feet.
