Grow and Care for Mesquite guide illustration

Grow a mesquite in full sun and soil that drains. Mesquite is Prosopis, a desert shade tree with dark, fissured bark and pale yellow catkin flowers.

How to Grow Mesquite care summary diagram

Give it full sun, soil that drains, and little extra water once it roots

FactorRecommendedAvoid
SunFull sun for a mesquiteDo not site it in deep shade
SoilGarden soil that drains after rainDo not plant in a bog
WaterWater a new tree; then water deep and seldomDo not keep the roots on a lawn drip
DroughtTolerates dry spells once the roots takeDo not skip first-season water because the tree is drought-tolerant later
FeedLittle or noneDo not dump nitrogen that makes weak, fast wood
ThornsKeep thorny kinds off walks, doors, and play areasDo not plant a spiny stem over a path

A mesquite wants full sun and well-drained soil. Water a new tree through the first season. Once the roots take, water deep and seldom, with emitters at the dripline, not against the trunk. Extra water in a lawn pushes shallow roots and weak wood that can topple in wind. [1] Leaves drop in a dry spell or after a hard freeze. That is normal. Do not add more water just because the canopy looks thin. [2] honey mesquite wants that same drain. Pick the kind on Types of Mesquite.

Does a mesquite need full sun?

Full sun is the rule. A mesquite will lean and look sparse in shade. Do not site a landscape tree on a north wall.

How often should I water a mesquite?

Water a new tree until it roots. After that, water deep and seldom. Do not leave the roots on a lawn drip.

When does a mesquite bloom?

Pale yellow catkins open in spring, and a wet summer can bring a second flush. The flowers are a bee tree, not a cut-flower crop.

Plant a young container tree in fall or spring, with the flare at grade

Plant in fall or spring, when you can water the first season. Buy a one-gallon or five-gallon pot, not a boxed giant. The taproot does not like a move once it is in the ground. Set the flare even with the surrounding soil, or a little above it. Soil piled against the trunk leads to rot. [3]

  1. Plant in fall or spring. A small nursery pot is the usual start. Tease circling roots if the pot is bound.
  2. Dig a hole as deep as the root ball and a little wider. Set the flare even with the surrounding soil.
  3. Backfill with the soil you dug. Do not add a rich amendment that holds water against the trunk.
  4. Water in once. Keep the first season watered. Do not skip that because the tree is drought-tolerant later.

When should I plant a mesquite?

In fall or spring, when the soil is workable and you can water the first season. Do not plant into a low wet spot.

How deep should I plant a mesquite?

Set the flare even with the surrounding soil. Do not bury the trunk, and do not lift a mature tree.

Raise low branches in late winter — do not strip the inner wood

Wait until late winter, before the spring flush, so you can see the structure. Raise low branches off walks and doors if people need to pass. Wear gloves. Young wood carries thorns. Keep a one-trunk tree or a multi-trunk form; both are fine if the inner twigs stay on the limbs. [4]

  1. Wait until late winter, before new growth.
  2. Raise low branches so people can pass. Wear gloves.
  3. Cut crossing or dead wood. Do not strip the inner branches so all the weight sits at the tips, and do not top the tree into a ball. Skip a heavy cut in summer heat.

When should I prune a mesquite?

In late winter, before the spring flush. Raise low branches then. Do not strip the inner wood in summer heat.

Why keep the inner twigs?

Inner wood shades the limbs and keeps the weight off the tips. A stripped limb snaps in wind.

Not palo verde — and not acacia

Palo verde is Parkinsonia. That tree has green bark and yellow pea flowers. A mesquite has dark, fissured bark and catkin flowers, so the two are not interchangeable — see How to Grow Palo Verde. Acacia is a different pea-family tree — see How to Grow Acacia. Those puffball flowers are not mesquite.

Is a mesquite the same as a palo verde?

No. Mesquite is Prosopis. Palo verde is Parkinsonia. Dark bark is the mesquite tell.

If the tree sat wet in a lawn and the roots are at the surface, move the emitters out to the dripline — do not add more frequent water.

FAQ

Can I grow a mesquite in a pot?

A deep draining pot can hold a young tree for a season or two. The taproot circles and strangles if it stays in a pot to maturity. Plant it in the ground while it is still small.

Can I grow mesquite from seed?

Buy a small container tree instead. Seed needs a nick or a soak, and named kinds do not come true. The usual start is a one-gallon or five-gallon pot.

What is a mesquite girdler?

A beetle that cuts a twig so the end dies and hangs. The damage is usually cosmetic. Cut the dead stub back to live wood. There is no useful spray once the twig is already cut.

When can I pick the pods?

Pick dry tan-to-red pods from the tree before the monsoon on Harvesting Mesquite.
