I have an Ixora in a container and it only has 5/6 spindly branches and doesn't bloom. How do I get it to more of a shrub (fuller looking) and to produce flowers? I live in South Texas and the plants are south facing on a porch in 2-3 gallon planter pots.
There can be a few reasons for the lack of growth and blooms.
Ixora need full sun locations.
Your plants also may not have a large enough pot to grow in and do not have the correct soil content for good growth.
Ixora have some specific growing and nutrition needs.
Here is a link that will refresh you on the care requirements.
