About 5 months ago I purchased a Chinese Flowering White Serissa and it was doing great - lots of flowers and new growth. I then got sick and was bedridden for a week and unable to water it. Though I watered it as soon as I was able to walk around. Since then however, it has not flowered and most of it's leaves yellowed and dropped. I cut it back to promote new growth and I was rewarded with new shoots of leaves however now they too are starting to wither and die, they curl almost as if I'm over watering. I did notice some tiny white insects crawling around in the soil and sprayed some volk oil and have not noticed them since, but now I am at a loss on what to do as the tree gets new shoots but they also are starting to curl and fall off. Help!
