Citrus

I have a problem with my lime bush. It has a black film over some of its leaves and what appears to be tiny whiteflies. It’s a large bush but produces very few limes. How can I improve the health of this bush?

Why is my lime tree not producing fruit and even though nearby my lemon tree is?

Why is my lime tree growing leaves that are mottled with yellow?

I recently bought three citrus trees; Orange Harwood Dwarf (grows 1.5 meters high), Lime Bearss Dwarf (grows 1.5 metres high) and Tangelo Seminole (grows 2.5 metres high).

I’d like to have them in pots which can be moved in the cold winter months. How big a pot should I use and what compost/ pot mix would be best?

I use kaffir lime leaves a lot in Thai cooking but my plant’s leaves have become quite yellow and speckly looking. How can I help it?

I have been having great difficulty in growing my mandarin tree in Grenada Village. I have used all sorts of products and have consulted my garden book and nurseries. Can you help me?

I am considering moving a Clementine mandarin tree in September to a northerly position. It is one metre high and was planted 4 years ago. Should I partly wrench it a month before uplifting?

Shortly after planting my grafted trees lost many of their leaves and some branches started to die off. The leaves that stayed are dry and curled up. Some trees are blossoming, but there is no new growth. 

When is the best time to move citrus trees?

I have a Best’s seedless navel orange tree growing in a large pot. It had four oranges on it last year, but this year it has only one. Does it need to be planted out and what feeding is best?

I’ve had a Kumquat tree for about 5 years and have never had any fruit. I have a Kafir Lime as well which leaves are prolific, but should it have fruit too?

Our grapefruit tree is about 6 years old and although fruiting, the fruit is very dry. I have used citrus fertiliser on the drip line and water it in summer. How can I grow juicy grapefruit?
