Root Rot

Overwatering

To address root rot in Mona Lavender, first, allow the soil to dry out before watering again. Ensure the pot has adequate drainage holes and consider repotting the plant into fresh, well-draining soil. If the plant is severely affected, trim away the rotted roots before repotting. To prevent recurrence, water the plant only when the top inch of soil feels dry to the touch and ensure the pot is not sitting in water.

Leaf Drop

Underwatering

Mona Lavender requires consistently moist soil to thrive, but not waterlogged conditions. To address underwatering, establish a regular watering schedule, ensuring the soil is moist to the touch but not saturated. During hotter months, watering may need to be increased. Consider using a moisture meter to better gauge the soil's moisture level. Mulching can also help retain soil moisture. If the plant has been severely underwatered, a thorough soaking may be necessary to rehydrate the soil and roots.

Spider Mites

These tiny spider-like pests cause damage by sucking sap from the undersides of the Mona Lavender's leaves, leading to speckled, discolored foliage and potentially reduced plant vigor.

To manage spider mites, start by isolating the affected plant to prevent the spread to others. Increase humidity around the plant, as spider mites thrive in dry conditions. Rinse the leaves gently with water to dislodge the mites, or use a soft cloth dipped in soapy water to wipe them off. For severe infestations, applying neem oil or insecticidal soap according to the product's instructions can be effective. Regular monitoring and early intervention are key to preventing major outbreaks.

Powdery Mildew

Fungal infection

Powdery mildew is a common fungal issue that affects Mona Lavender, manifesting as white, powdery spots on leaves. To manage this, ensure good air circulation around your plants and avoid overhead watering to keep foliage dry. Infected leaves should be removed and destroyed. For severe infections, apply a fungicide specifically labeled for powdery mildew, following the manufacturer's instructions carefully. Preventative measures include planting in well-draining soil and spacing plants adequately.
