Citrus Leaves Curling

Whiteflies in Temp AZ

Insufficient soil water is probably the most-common general cause of curling citrus leaves

This can occur at any time of year but is most common with trees in areas that aren’t regularly irrigated, during long periods without rainfall, and during hot weather.

Water slowly and deeply preferably using chlorine-free water. Mature citrus trees in dry soil may need 12 hours or more of watering with a hose on a slow trickle at one or more locations around the trees to resolve drought stress.

An organic mulch may help retain soil moisture and improve soil over time. Cover most of the soil surface under citrus trees with up to 2 inches of coarse mulch, extending past the driplines, but avoid placing mulch within a foot of the trunk of mature trees, and keep mulch several inches away from major surface roots.

For more information you can download the irrigating citrus trees file to the right -it is a PDF file put out by the cooperative extensions - and we have been using the information in it to grow citrus in Maricopa county for years,

In Maricopa county we have at least two other insects that effect the health of citrus trees one is the Ash whitefly (watch the video) and the other is the Asian citrus leaf miner which arrived here in in 2011 and breeding up to 15 times a year,

the Asian Citrus Leaf Miner was in every citrus tree I looked at for several years.

The population grew unchecked well into the summer of 2019,. So for at least 8 years, the leaves on your citrus trees have been producing far less energy than normal.

Because of this the reserve cells are dangerously low. Biologically speaking, your citrus trees have run out of gas.

Because it has no natural predator in Arizona there was nothing to keep it in check. However now it competes with the Ash Whitefly.

It takes years but eventually a citrus trees reserves will be drained to the point that it can no longer defend itself against any insects or soil born fungus.

That’s where we come in, if it’s not too late we can get you started on a program to restore the energy reserves of your trees.
