I bought my Hydrangea plants (4 pots) from Home Depot Garden more than a week ago. Last Sunday I transplanted it to a bigger container about 18" in diameter. We have a very small yard and there's already a big tree in it so I decided to just plant it in a container. I followed the instructions on how to plant them. I watered it thoroughly and put miracle gro quick start. I noticed this morning that some of the stems are drying up. Most of them have brown spots on the stem. The leaves are still ok. I am not yet sure what type of Hydrangeas they are. It has small green flowers which looks like brocolli. I live in Ontario Canada and the plants get a lot of sunlight from my backyard (morning and afternoon sun). I checked the soil underneath the mulch and it is still moist. Can anybody please tell me what wrong with my Hydrangea?
Any comments will be greatly appreciated. Thanks.
