|I bought a dwarf Valencia orange tree from Home Depot the summer of 2008. It had 1 flower that bloomed in 09 and the 1 fruit was dry and inedible. No flowers this year. I found strange looking small brownish/tan bumps on some branches. I used a paper towel to wipe some off & the bumps smeared on the towel. I hosed off the rest of them. Leaves are healthy. Any idea what's wrong?

|I'm not exactly sure why your tree is not flowering. Full sunshine, ample water and regular feeding are about all orange trees need to perform well. If the one orange your tree produced was dry inside your tree probably needs more water than you are supplying. A deep soaking once or twice a week during the growing season will correct the problem with the dry fruit. Try feeding your tree with a fertilizer formulated for citrus trees, in the amounts as indicated on the fertilizer package (which will vary according to the size of the tree). Citrus trees should be fed 3-4 times per year. The bumps on the branches are scale insects. Removing them the way you did was a good approach. Be on the look out for more of them and squish them as soon as you find them. Good luck with your tree!
