how do alzaleas growth spread
Our sweetpea bush which was prolific last year has now began to die; yellow, withered leaves, leave leaves falling off and generally looks as though it will not revive. Other friends are having the same problems - do you have any answers to this ?
Sweet pea shrub requires minimal watering. If the soil is staying too wet, the roots will suffer and leaves turn yellow as a result. Imbalances in nutrients in the soil can also lead to yellowing. Potential problems are low magnesium, high potassium and low iron. A soil test to determine whether you have deficiency or toxicity of specific nutrients is important as just throwing down extra nutrients may worsen the problem. Check the website of your state's extension service to see if any diseases are in your area.
