I purchased my meyer in the mail 1 year ago. I spent the winter in the house and is outside in the full sun in the summer. It grew to 4 times its size when it was outside. I brought it into the house this fall and was suprised when it kept its leaves and a month later exploded with flowers. Its beautiful. However, the flowers fall off at the slightest touch. Now the leaves are green still but they also fall off very easily. Every day I clean up more leaves and flowers. I never got any fruit. This tree is planted in potting soil and has been given 1 application of citrus food. Its in the sunny spot in my house. I water 1 or 2 times a week, never to run off. One branch is completely bear of leaves. I do see one new leaf coming out. Also, I noticed little nat like things flying around the soil but the plan shows no chewing or webs etc. I love this little trees smell. What should I do?
