It is not a flowering plant, so I don't think so. I haven't had any trouble caring for it for a long time, but suddenly, no matter what I do, it only gets worse.

Once again, you guys have solved a problem in minutes that i have spent much longer trying to figure out! Shoulda come here first. :)thank you!

Yes, Hydrangea.

I personally fertilize with every watering at 1/4 strength. I do recommend that you use some fertilizer seeing that you haven't fertilized for a long time. For the first time around water with a full strength high Phosphorous fertilizer then reduce to 1/4 strength on the following waterings. Use the high Phosphorous fertilizer for 2-3 weeks then use a balanced fertilizer for 4 weeks, then back to the High Phosphorous one for 2-3 weeks,.... and so on. The high Phosphorous fertilizer helps induce flowering (no guarantees :) but continuous use can cause other deficiencies due to the high Phosphorous content and that is why I recommend the use of a balanced one in between. Use a fertilizer that contains chelated micro nutrients (Iron, Manganese,....) beside the macro nutrients (Nitrogen, Phosphorous, Potassium). Some folks will say not to fertilize during the winter time but I fertilize year round and Hoyas like carnosa will happily grow and bloom in the middle of our cold winters here ;) I saw another thread of yours where you where looking for Hoya suppliers. I don't know of any on-line stores in Spain but I know of a few in Holland, Italy and Germany. Drop me a message an I can give you the links if you're interested. Milan
