I'm a new gardener who planted three small hydrangeas less than one week ago. I have been watering them once a day for about 30-45 minutes with a soaker hose. I just noticed that the stems on all three plants are speckled with reddish, brown spots. Is there something wrong with them? I don't remember if they were there when I bought them. I'm also wondering, since they are very young and only stand about 6 to 8 |
