How do you grow Correa Dusky Bell plants?
planted young Correa Dusky Bells -2 of- about 3metres apart in sandy/loamy/dirt/organic soil mix- which already supports other more mature natives nearby- Osmocote for natives added at planting end of march.Bark mulch on surface, clay /gysum soil couple feet below. since colder wetter weather began and the few flowers on the plant dropped off, leaves have turned deep red purple but still feel soft and pliable. One plant displays these symptoms the other still has green leaves and flowers intact.
I can understand your concern as you don't want to lose this beautiful native shrub that is growing in your garden. I don't think you have too much to worry about. I, like you, think that because of the continual, wetter cold weather we have been experiencing as of late, the soil has become saturated and native plants are beginning to suffer. As long as the drainage is good, your plant will recover. There is a Yates product called Anti Rot which is a systemic fungicide which controls root rot in citrus as well as ornamental plants. It is widely used by native plant enthusiasts. This product, when sprayed on the leaves, travels down to the root system. It will aid in boosting the plant's self defence mechanism, giving it the ability to prevent disease from taking hold. I am sure you will find having this product in your garden shed will be of great benefit to your garden plants.
