Saving an Eldarica Pine After Grasshopper Defoliation

Grasshoppers stripped needles and chewed bark on Michelle's Eldarica pine—over half the foliage gone overnight. The tree can recover, but it needs immediate support.

First, water deeply and consistently for 30–60 days. Apply a balanced slow-release fertilizer (10-10-10) at label rates—don't overdo it. The goal: reduce stress so the tree can push new growth.

For organic grasshopper deterrence: plant barrier crops—horehound, cilantro, calendula—around the tree. Spray garlic oil repellent: steep 3 oz minced garlic in 1 oz mineral oil 24 hrs, strain. Mix 1 tsp fish emulsion + 16 oz water + 1 tbsp castile soap. Combine slowly with garlic oil. Store sealed. Dilute 2 tbsp concentrate per pint water and spray foliage.

Reapply after rain. Monitor for new growth. If the cambium (inner bark) wasn't girdled, the pine has a 50%+ chance. Patience and care are key.
