Porter Weed



This is a very tropical plant and performs best in the spring-summer- and fall. During the winter months, it will tend to be less of a performer.

Yes using some soap and water will " clean" your plant form insects.

This plant also does love hot temperatures... so the winter can not provide as much as it does during the great growing season.

It may die back completely for the winter..... mine does. And I live in zone 8b-9. But if you are in a warmer zone and prefer to keep taking it inside and then outside again keep it up........
