    She should put the pot in a bucket of water so that the pot, but not the plant, is submerged and leave it there for half an hour or so. Then remove the pot, let it drain, and put the plant where it receives bright, but not strong, light. Keep the soil moist until there are signs of new foliage, and do not fertilize before then.

      @Douglas Hunt Thank you for the advice—very thorough. We will keep you updated on the progress of this poor houseplant.

    Water. Take outside and use insecticidal soap, she may have spider mites. Lots of house plants get them. Don't fertilize when in this state. You may also need to repot it in fresh soil once hydrated.

      @Cecelia Hi Cecelia, we've been hearing mixed reasons to fertilize or not fertilize the tree in this state. Some people say it will shock the plant and some people say it's necessary. What has been your experience?

    This may be a bit off the wall but is it possible the cat urinated on the pot inside or on the sides... I have a male chiuahuah who marked his territory on a flower pot containing my ficus tree that Ive had for years... the urine was way too strong and by the time I noticed signs of problems the tree was about gone... I took it outside this spring and flooded it several times and let it drain out then repeat... Its coming back slowly... just a thought to consider..

      @Buster Evans We hadn't considered the possibility of cat urine but it could have contributed. Meredith will look into it but it's great to hear you had a similar experience and things are looking up.

    Hi, I would side on not fertilizing right away. However, a half dose of miracle grow won't hurt as it will be diluted. Especially if u think the cat may be the culprit....that ammonia would burn the roots. If you think seriously kitty was to blame, repot with fresh soil.

    No, don't fertilize until the tree starts to recover and show growth. I think that urine would probably show signs of burning on the leaves. Question #1 - have you had the tree for more than a year? Olives are mediteranean and may drop their leaves in a cool fall naturally or as a sign of stress. Google this for info. Question #2 - see if you can ascertain if the tree was either OVERwatered or UNDERwatered. Make sure you know what the status of the soil is now by gently probing or tipping the roots/soil out of the pot. See if it looks like roots are dehydrated or rotting or for pests. I am NOT a fan of soaking a plant for extended time, especially when they are arid land plants, and particularly when you don't know what the problem is! If you see indication of insects, treat accordingly. Give reasonable waterings, and let dry out slightly. You can keep under glass (a makeshift conservatory using a bowl, plastic wrap, etc) so that it still gets light, but temp/humidity are more constant (but not steamy inside). This will help you see if insects are at fault (Google thrips just in case).
