Posts: 0 05-04-04 21:46	Tags : None Hi,I planted an orange tree last year next to a lemon tree.The orange tree has gradually lost most of its leaves after turning a pale green.It is however in bloom with a continual stream of ants climbing the trunk to the blooms. The lemon tree is 2 yards away, in full bloom and showing lots of new leaf growth. Any ideas on how to irradicate the ants? Will the tree reproduce leaves?

Meanwhile could you give us a little more information - like how big was the tree when you planted it, and was it container-grown? The leaf loss could be simply to the shock of being transplanted, in which case keep your fingers crossed for recovery! About the ants - for all I know Lynne is right. But I recall many of the trees I've seen in Greece having the bottom metre or two of the trunk painted white. I don't think this is a local style of ornament - I think it's to stop something getting up the trunk and into the tree. It might be worth asking some of the locals for advice.

The grease in a tub soon hardens off and the ants walk over it, so I find it better to use the sticky paper type. You are what you drink, and I'm a bitter man.

Established Tree Posts: 21007 06-04-04 18:32 Retired Auctioneer	OK, have just had a quick trawl around Google, and if you do a search on 'citrus problems' there's an awful lot there. This might interest you: Q. Most of the Leaves on My Young Citrus Tree Are Yellowing and Dropping. Why? A. Foot Rot disease may be the problem. This fungal disease attacks the tree at or just below ground level, rotting through the bark and conducting tissue thereby stopping the flow of water and nutrients in the tree. It is aggravated by planting citrus too deep (the top of the root ball should be flush with the soil surface), mulching citrus (an excellent idea on every other plant, but not citrus) poor drainage (citrus likes very well drained soils) or overwatering (citrus will thrive on an inch of water (or less) a week. Yellowing veins is a typical symptom of foot root or root rot disease. Link: edis.ifas.ufl.edu/CH087 But there might not be a problem at all - see here: Yellow Citrus leaves in Winter usually not a disease symptom In general there seem to be a lot of dire warnings against planting citrus too deeply and not having sufficient drainage.
