I first noticed these little black pests that are about two millimeters long when my rose leaves began turning yellow and falling of. I treated my rose for fungus at first but that only got rid of the yellow leaves for a week or two. Now, my plant is experiencing stunted growth and some leaves are turning brown at the tips despite a regular watering regimen. I also noticed that these little black aphids are more prevalent. Should I try diatomaceous earth since there are no new blooms?? Are should I stick to the soapy water method??
