Ensuring A Strong Start

Planting Tips: Ensuring a Strong Start

  1. Location: Choose a site with full sun to part shade and good air circulation.
  2. Planting Depth: Dig a hole twice the width of the root ball and as deep as the root ball itself.
  3. Soil Preparation: Amend heavy or poor soil with compost to encourage strong root development.
  4. Spacing: Plant 5m - 10m apart for individual trees, closer for windbreaks.
  5. Watering: Water deeply after planting and regularly during the establishment phase.

Post Planting Care

When planting a new tree or shrub, proper watering is essential to ensure healthy establishment and long-term growth. Follow these guidelines to give your plant the best start:

  1. Immediately After Planting:
    Water generously right after planting to settle the soil around the roots and eliminate air pockets. This helps the roots make good contact with the soil.
  2. First Three Months (Establishment Phase):
    The initial three months are critical for root development. Water deeply twice daily (morning and evening) to encourage strong, deep root growth.
  3. Irrigation Systems:
    If using an irrigation system, adjust it to provide adequate water during the establishment phase. Ensure the water reaches the root zone without overwatering.
  4. Weather Considerations:
    Adjust watering based on weather conditions. Increase frequency during hot, dry periods and reduce it during cooler, wetter seasons.
  5. Ongoing Care:
    After the establishment phase (3 months), gradually reduce watering frequency but ensure the plant receives consistent moisture, especially during dry spells.

Long Term & Ongoing Care

Caring for Your Alnus jorullensis

Watering

  • Establishment Phase: Water deeply 2-3 times per week for the first 6 months.
  • Ongoing Care: Once established, drought-tolerant but benefits from occasional deep watering in prolonged dry periods.

Pruning

  • Timing: Prune in late winter or early spring to remove dead or weak branches.
  • Method: Trim selectively to maintain shape and encourage strong branching.

Fertilization

  • When to Fertilize: Apply a balanced slow-release fertilizer in early spring.
  • How to Fertilize: Spread evenly around the base, avoiding direct contact with the trunk.

Pest & Disease Monitoring

  • Pests: Generally pest-free but may attract occasional aphids or borers.
  • Diseases: Resistant to most diseases; good airflow helps prevent fungal issues.

Mulching

  • Benefits: Retains moisture, suppresses weeds, and regulates soil temperature.
  • Application: Apply a 5-7 cm layer of mulch around the base, keeping it clear of the trunk.

Winter Care

  • Cold Protection: Naturally frost-tolerant, but young trees may need extra protection in extreme cold.
