Mimosa Tree Planting Instructions

Mimosa trees (Albizia julibrissin) are fast-growing, drought-tolerant deciduous trees that grow to form an airy, umbrella-like canopy. They are known for producing a plethora of fluffy, fan-like fragrant pink flowers that are highly attractive to honey bees. Although originally from China, mimosa trees have been naturalized throughout numerous areas in the southern United States. Plant a mimosa tree away from ponds, pools or fountains because its littler (leaves and flowers) can be messy.

Choose where you want to plant the mimosa tree. For best growth choose a planting site that is in full sun, suggests Floridata.

Turn over the soil in the planting are using a spade or a garden fork down to a depth of between 18 and 24 inches. Sift through the soil using a metal rake to remove all clods, rocks, sticks, roots and weeds that can interfere with the growth of the mimosa tree.

Amend the soil in the planting site according to the type of soil. Spread out a 2- to 3-inch layer of coarse sand over the soil in the planting site if the soil is sticky, clay-like or heavy. If the soil is light and sandy, spread out a 3- to 4-inch layer or manure, aged compost, leaf mold or any other similar type matter. Mix the amendment into the soil using the spade or garden fork.

Dig a planting hole for the mimosa tree that is 12 inches deep by 10 inches wide if you are planting from a 1-gallon planting pot. If you are planting from a 3- or 5-gallon planting pot, dig a hole that is 18 to 20 inches deep by 16 to 18 inches wide.

Cut along the side of the planting pot, beginning at one of its drain holes, using a pair of multipurpose snips. Do this all around the pot until you can remove the mimosa tree from its growing container.

Rough up the root ball of the mimosa tree by spraying water around the root ball to remove approximately 1-inch of soil. Loosen the roots with your fingers. If there are any encircled or ensnared roots, cut them off with a pair of snips.

Plant the mimosa tree into the planting hole. Check to ensure the top of its root ball is sitting level with the adjacent garden soil. Hold the mimosa tree vertically in its planting hole while you scoop in soil around the root ball to secure it in place.

Fill the planting hole full with soil, packing it down as you proceed. Water the mimosa tree with 1 to 2 gallons of water if you planted from a 1-gallon pot. If you planted a mimosa tree from a 3- or 5-gallon pot, provide the tree with between 3 and 5 gallons of water.


To help watering a mimosa tree, after planting, create a 3 to 4 inch high berm of dirt around the mimosa tree. This will help the water to pool up and allow it to sink down to the roots.
