Help for (improving!) gardening novice re: lemon tree

Hello

I am based in Melbourne, Victoria and own a small 'Variegated Lisbon Lemon' tree. It is about 5 foot high and initially when purchased, featured approx. 8 or 10 healthy mature lemons. Between Feb and late Oct 07 the tree held no fruit, however since early November 07 it has produced and is currently growing 18 - 24 very small 'baby' lemons.

On return today from a 5 day break away, we found 10 or so of said 'baby lemons' on ground (we watered before going away and do so approx. 1 - 2 times per week on average whilst at home during Spring and Summer months). The leaves and branches - on most of the upper-half of the tree, are covered with brown and yellow 'blisters' and there are hundreds of ants crawling over same area.

Any advice/knowledge as to what this condition is and how I go about rectifying the situation would be greatly appreciated.

Many thanks in advance...

Looks like scale to me.. White Oil will fix that problem.

yep, a very nasty case of scale. neem oil will work too, just dilute and spray all over those nasties. The ants are there because the scale produces honeydew - a sticky substance that the ants like.

I had exactly that on an allyogene (native hibiscus). The wite oil didn't do anything to the scale - just kept the ants off for a while. Eventually the shrub died. I'll have to keep a closer eye on it next time.
