Autumn is a busy season for ripening of citrus fruit. Unless you’re getting regular autumn rains, give citrus a deep drink each week. Inadequate soil moisture can affect fruit quality, so it’s important to ensure the water is getting down into the soil.
It’s as easy as mixing 15mL of Yates Waterwise Soil Wetter into a 9L watering can and watering over the root zone (or potting mix for container grown citrus). This will help the water penetrate below the surface and down into the roots where it’s needed.
And to help keep citrus leaves healthy and green and nourish the developing fruit, feed each week with Yates Thrive Citrus Liquid Plant Food. It contains a special blend of nitrogen to promote green leaf growth, phosphorus for strong root development and potassium to encourage flowering, healthy plants and quality fruit.
Just mix 2 capfuls into a 9L watering can and apply around the root zone of in-ground and potted citrus.
Citrus collar rot prevention
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. 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 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, which improves the air flow around the trunk.
Applying mulch over the root zone is very beneficial, 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 Yates 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 Yates Anti Rot as a protective spray during damp conditions will give more effective control than waiting for symptoms to appear.
