6. Curled Or Distorted Leaves: Hidden Pest Damage Under The Canopy
Curled or distorted leaves can indicate pest damage, often from insects like aphids, thrips, or spider mites. These pests feed on leaf sap, causing physical deformities. Inspect the undersides of leaves for signs of pests and consider using insecticidal soap or neem oil for treatment. Encouraging natural predators, such as ladybugs, can also help control pest populations. Regular monitoring and maintaining plant health through proper care can reduce the risk of pest infestations.
7. Chewed Or Ragged Leaf Edges: Slugs, Beetles, And Other Nighttime Raiders
Chewed or ragged leaf edges are typically caused by slugs, beetles, and other nocturnal pests. These creatures thrive in moist environments and often hide during the day. To manage them, set up slug traps or hand-pick beetles in the evening. Barrier methods, like copper tape or diatomaceous earth, can deter slugs from reaching plants. Regular garden maintenance, such as removing debris and dead plant material, can also reduce hiding spots and breeding grounds for these pests.
8. Reddish Or Bronze Discoloration: Cold Snap Or Sunburn Stress After Winter
Reddish or bronze discoloration on hydrangea leaves can result from a sudden cold snap or sunburn, particularly after winter dormancy. New leaves are especially vulnerable to temperature fluctuations. If a cold snap is expected, cover plants with frost cloths or blankets overnight. For sunburn, ensure plants are not exposed to harsh afternoon sun and gradually acclimate them to increased sunlight. Consistent care and attention to weather changes can prevent these stress-related issues.
