PUT A LITTLE ZING IN CITRUS
Autumn is a busy season for ripening of citrus fruit. Unless you’re getting regular autumn rain, give citrus a deep drink each week. Inadequate soil moisture can affect fruit quality and overall plant health.
But poorly drained soil or prolonged wet weather can lead to the development of root and collar rot diseases. These diseases affect the ability of the citrus trees to effectively absorb soil moisture, leading to wilting, poor plant health and sometimes plant death if left untreated.
Here are steps to reduce the incidence of citrus collar and root rot diseases:
Remove lower hanging branches of citrus trees, which improves the air flow around the trunk.
Apply mulch over the root zone, which helps to keep the roots moist. However, keep mulch away from touching the trunk itself, as this can keep the trunk wet, which can promote collar rot.
Apply an anti-rot systemic fungicide over the foliage during autumn. The fungicide travels down through the plant and into the stems and roots, helping to control root and collar rot diseases.
