🪴 Care & Maintenance Guide

🌞 Light

Best: Full sun
Avoid: Deep shade (slower growth, thinner canopy)

💧 Watering

Establishment: Water regularly for the first growing season to develop roots
After established: Moderate drought tolerance—deep water, then allow soil to dry slightly
Tip: Palms dislike constantly wet soil; good drainage is essential

🪨 Soil

Well-draining soil is best (sandy/loamy ideal)
Tolerates many soil types if drainage is good
Containers: Use a palm mix and ensure drainage holes

🌡️ Temperature & Humidity

Prefers warm climates and handles heat well
Protect from hard freezes when young; avoid prolonged cold + wet soil

🌿 Fertilization

Feed 2–3x per year (spring/summer) with a palm fertilizer that includes micronutrients (Mg/Mn/Fe)
Tip: Proper palm nutrition helps prevent yellowing and leaf distortion

✂️ Pruning

Remove only fully brown fronds
Avoid over-pruning (“hurricane cutting”)—it stresses the palm and reduces vigor
If “skirts” are desired, remove carefully and safely (tall palms may require a professional)

⚠️ Common Issues

Yellowing fronds: nutrient deficiency (use palm fertilizer with micronutrients)
Brown tips: underwatering, salt buildup, or wind/heat stress
Slow growth: low light or poor nutrition
Pests: occasionally scale—treat early if detected

📦 What You’ll Receive

One healthy Washingtonia robusta (Mexican Fan Palm) in a nursery pot.
Natural variations in height, trunk thickness, and frond fullness are normal. Minor cosmetic markings may occur from normal growing/handling.

Acclimation Tip:
Allow 2–4 days after delivery before planting or repotting. Place in full sun gradually if it was grown under shade cloth. Water lightly at first, then transition to deep, less frequent watering once established.

⚠️ Safety Note

Fronds can have sharp edges/spines along the petioles on some palms—use gloves when handling. Large palms can shed older fronds; plant away from roofs/structures if possible and maintain regularly.
