🌱 How to Care for Avocado to Prevent Mealybugs?

💧 How to Water

Water your avocado tree approximately every 7 days in summer and every 10-14 days in winter. Allow the top 5 cm of soil to dry out before watering again. Overwatering and poor drainage are the leading causes of root rot, the most serious disease affecting avocados.

☀️ Lighting

Avocado trees need full sun to fruit properly. Place in the sunniest spot in your garden with at least 6-8 hours of direct sunlight daily. In very hot climates, some afternoon partial shade can be tolerated.

🪴 Ideal Soil

Use well-draining, fertile soil with a good proportion of organic matter. Avoid heavy clay soils that retain water. The ideal pH is 5.0-7.0; outside this range, iron and zinc deficiencies may appear. A mix of loamy soil with coarse sand works well.
