Please help…. I planted some hydrangeas last year; they have grown some, (not much), have just few leaves that have ugly rusty spots and some blooms. The blooms are whitish, but the varieties I planted were pink and blue.... Can anyone tell me what I'm doing wrong...I give then plenty of water and they are planted in shade. Someone suggest spreading egg shells around them..will that help?.. Thanks a lot.. Espe
Hi Espe, Your hydrangea may have been mislabled if it's white. You can look here to see if you can id the flowers to see which one you have. http://www.hydrangeashydrangeas.com/index.html There are a couple of different diseases that come to mind. Take a look here to see what fits. http://www.aces.edu/pubs/docs/A/ANR-1212/ANR-1212.pdf Newt
they like Acidic water, see if yours is alkali. also rust spots are a notorious disease these plants get.
Jodeecee, with no disrespect meant, not all hydranges like acidic water. It depends on which variety you are growing and what your soil pH is. http://www.extension.umn.edu/distribution/horticulture/components/1731-29.html This chart shows the blue hydrangia as liking an acid pH, but the pink and white prefer an alkaline one. http://homeharvest.com/flowersornamentalstreesshrubsphpreference.htm Newt
