We were given a Ceanothus in October. About 5ft tall in a pot with cane. It has been on sheltered patio since in pot. Started looking sorry for itself. Drooping leaves. All green but dry and crispy. Signs of flower heads but they're dry too. Have now planted in ground and hoping it will revive but looks worse!!. Complete novice gardeners. Some advice says they go like this with too much water and some say with not enough! Help! (Gift was from next door neighbour!!)
It could be a watering issue. Also, does it get any sun on the patio? The move to inground should help if it is in full sun. It might be experiencing transplant shock on top of the dry leaves. I suspect the leaves will fall off and new ones will grow. You can scrape off some of the stem and see if it is green underneath. If it is, the stems are still alive.
They are susceptible to powdery mildew and leaf spot disease. If the plant was overwatered, it could be root rot. Did you notice any mushy roots when you replanted? If so, it may not recover.

Have been given a small but very healthy ceanothus California in a pot but have been told this is the wrong time to plant it how should I proceed
They are not very picky, but spring or autumn will be appropriate. Any time the weather is mild for extended periods will be ideal.

I have a Ceanothus 'Lemon Ice' that I bought with one (trunk) and variegated leaves. Two more trunks have grown next to it with plain green leaves. Can I cut off the two trunks without harming the original plant.
These are not grafted, and do not have a tendency to revert. Likely, the plants growing next to your Ceanothus are not related, and need to be killed as soon as possible.

I was testing the PH and noticed that it looked like the tree is leaking orange goo that seems to be turning the bark black. This is a old tree 14+yrs old. PH was 7. Leaves appear to be okay and the tree is starting to get it's flower buds.
This is slime flux. Usually, this is bacterial and will not kill your tree. Feeding the tree and applying a fungicide will correct the issue, usually.
