I love this tree so much I now have 2!
Just a suggestion when planting the tree in the ground, make sure you stake it well. The roots are shallow and in a strong wind it will blow over.

Planting & Care

It's Easy to Plant & Care for Your Cassia Tree

Step 1: Dig Your Hole

Select a site with full to partial sun and moist or well drained soil for your Cassia Tree.

First, dig each hole so that it is just shallower than the root ball and at least twice the width.

Then loosen the soil in the planting hole so the roots can easily break through.

Use your shovel or try dragging the points of a pitch fork along the sides and bottom of the hole.

Planting & Care

Step 2: Place Your Plant

Next, separate the roots of your Cassia Tree gently with your fingers and position them downward in the hole.

The top of the root flare, where the roots end and the trunk begins, should be about an inch above the surrounding soil.

Then make sure the plant is exactly vertical in the hole.

To make it just right, use a level.

Step 3: Backfill Your Hole

As you backfill the hole, apply water to remove air pockets.

Remove debris like stones and grass and completely break up any dirt clumps.

Water your Cassia Tree again after the transplant is complete.

how much watering does a cassia tree require?
sabel on Aug 30, 2014
BEST ANSWER: This tree needs regular water (an inch a week) the first season or two until the roots are established. Once established this tree actually has the most spectacular bloom display (late spring/early summer) when it is fairly dry. The rest of the year, it has average moisture needs, but requires good drainage.
what about roots are they damaging?
sergio f on Dec 16, 2014
BEST ANSWER: Roots are usually not a problem. It does grow to 30-40 feet across, and the roots grow to a similar width, so it will be best about 15 to 20 feet from a building or street.

is this cassia tree evergreen?
Nellie T on Dec 15, 2015
BEST ANSWER: Hi Nellie t.
I ordered a cassia tree, but I believe they sent me a casia bush as it does not have a single trunk but multiple branches. It is beautiful though. Blooming right now and has been in bloom for a long time and yes it is green all year when the blooms are gone. I have another cassia tree that is a definite tree and it is not in bloom. It blooms twice a year and it is also green all year. They are messy when the blooms fall of. Hope this help you. Sarah G.
