I am looking after a very small one in a plant pot, for a neighbour, which she keeps indoors on a windowsill. The soil that it is in looks baked hard, and she says not to water it from the top but to stand in a dish of water weekly but it is to be kept really dry. The tips of the leaves are turning brown - is this a sign it needs more water? I do hope it doesn't die on me!
I have watered mine this week, but not as much as other stuff. They are full of blossom. They are in huge pots and are quite big trees now - too big to lift up and place in a bowl of water. I did plant them in the correct stuff for olive trees which does bake hard and dry.
