Q.Oleanders
Our oleanders all grow to the side as if the wind has blown them all like that. They all are that way. Should we tie them up? We live in Houston, Tx not in a windy area. What do we do?
Do you suspect that the plants have shifted in the soil?
Can you pull the shrub to an upright position?
If they shrubs can be pulled into a more normal position, I would stake the plants.
Use protective clothing whenever working around Oleanders, as all parts of plant are poisonous.
Here are some links with more information.
