Sweetpea bush

Question

I would like to know why my sweetpea bush appears to be dying. Last year it was perfect. But leaves are now yellow, withering & looking very unhealthy. Friends aldo have the same problem with theirs.

Answer 1

Check for signs of pests, they may be very small. You describe symptoms of a possible infestation.
Neem Oil can be used on your plant.
