I planted Ruellia in several places in my landscaping and yard. I have a large patch in my backyard and just a few plants in other areas. I live in Florida and since planting (about 18 months ago), I had beautiful blooming plants. This spring I have no blooms at all. Not in the large patch nor the smaller patches (some have only 2 plants). What happened and how can I fix this? Thank you.
Different cultivators will bloom better then others.
Do you know the variety you have planted and it's characteristics?
Also crowding of the plants can inhibit blooming. If plants are crowded you can thin them out.
Also temperatures, many cultivators love to bloom in the heat of summer.
You may want to try an application of a bloom-boost fertilizer.

My Ruellia looks brown and dead. Should I cut it back and will it recover?
If it was exposed to temperatures down into the 20's, it will die back to the ground.
You can trim away the dead plant material.

I bought Ruellia plants in South Carolina and planted them in my garden in New Jersey, they are thriving. Now I want to make sure I take care of them for the winter so should I cut them back and cover them or wrap them ....what??? please help don't want to loose them.
Is the Ruellia plant toxic to Horses and Goats?
It is absent on many lists that indicate toxic plants for livestock, and isn't a concern. If you still have a concern, then it wouldn't hurt to remove the plant from the area, if at all possible.
Does Ruellia thrive in acidic or alkaline soil?
They thrive in acidic to neutral soil, but will tolerate most soil conditions. It is best to aim for a pH of 5.5 to 7 with 6 being just about optimal.

Why does my Ruellia foliage appear to be weeping or drooping? It is flowering, has new buds, gets about 6 or more hours full afternoon sun, water daily. Thanks for your help.
A weeping branching is actually part of this plants natural growing pattern.

The ruelia are taking over my flower beds. Going right under my house to get to other flower beds. I dug up the plants but tbere are so many roots left behind. Some smaller than thread. I have elephant ears in the main flower bed they were in.
