All of the trees are in large pots, and I fertilise them with blood & bone every two months, and sprinkle a quarter of a cup of dolomite lime once every six months. This routine seems to keep the trees healthy and free of pests. Touch wood, they will keep on going like this year after year.
Here is the Tahitian Lime:
This one is a massive Lemon tree, not sure of the variety;
This tree is a dual grafted mandarin, Emperor and Imperial;
And finally, a Lemonade tree. It is a cross between an Orange and a Lemon. It needs a bit of care because two branches have snapped due to the weight of the crop;
Each tree is flowering again, so It looks like they have a continuous cycle. I like citrus trees, because they are so easy to manage. I think I might put a few more in around the pool area against the new fence. Maybe a few varieties of orange would do the trick. Then I would have all the ingredients for my marmalade!
