Keep citrus trees happy and healthy
CITRUS love moist but well-drained soil, which creates a healthy environment for their roots to thrive and lower trunks to remain dry and healthy. Weeks of wet weather in some areas around Australia has created ideal conditions for root and collar rot diseases to
develop. These diseases affect the ability of citrus trees to effectively absorb soil water, leading to wilting, poor plant
health and sometimes plant death if left untreated. Here are a few steps you can take to reduce the incidence of citrus collar and root rot diseases: ◗ Remove lower hanging branches of citrus trees to improve the air flow around the trunk.
◗ Applying mulch over the root zone is very beneficial by helping 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 anti-rot phosacid 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. Using anti-rot as a protective spray during damp conditions will give more effective
control than waiting for symptoms to appear. ◗ As the fruit matures continue to feed trees each week with a complete and balanced fertiliser that has been specially designed to promote healthy citrus and help create good quality fruit. Citrus liquid plant food is an easy to use liquid fertiliser that’s ideal. Dilute two capfuls of liquid plant
food into a nine-litre watering can and apply over the root zone each week.
