Q. Yellow leaves on ceanothus

My ceanothus leaves have turned yellow and are falling from the plant. It is in a large pot. Do you think it is from over watering? How can I save the plant?

Yellowing leaves generally indicate a watering issue, to much or to little.
Container plants need daily water and even twice daily if the temperatures are above 85 degrees.

Check the water and if the top inch or so is dry, water.
Soil should be damp and not soggy.
Make sure the pot is well draining.

Q. Ceanothus

I have 2 large plants in pots, which have been fine for about 3 years and this year have shown that the flowers were about to open, but suddenly both bushes have shed many leaves and the flowers are drying up and falling off. Would they revive if planted in the ground, or could ants have got into the pots and caused this damage?

These are fast growing plants and they may have outgrown your containers.

They also will not tolerate wet roots and can die from root rot very quickly.
Check the soil.

Certainly pests or disease are also a possibility, so inspect the plant and soil for signs.
I do think this shrub would be best planted out into the ground.

Q. Ceanothus on a slope.

One side of our house has a slope that has been fully covered with Ceanothus for the past 5 years.
One side is partially in the shade and seems fuller and greener (image # 0703).
The side more exposed to the sun seems to be less full and has more yellow leaves, especially in during the summer (images # 0701 and 0702).
What do I need to do to change that for the better, greener all over.

Thank you for your time.

Marc.

It is just most likely that the higher level of sun sort of blanches that section of the ceanothus. Sunlight is something we have very little control of in these circumstances. You could try a nitrogen fertilizer such as blood meal to green up the lighter side. This article may help

This plant is hardy in zone 8-10. It would not winter over in a cold climate.
