Step 1: Watering

Watering your Zelkova bonsai correctly is crucial for its health, especially during the summer months.

  1. Ensure the soil remains moist but not waterlogged; this is especially important in summer.
  2. Reduce the amount of water during the spring, allowing the soil to dry slightly between watering.
Step 2: Fertilization

Proper fertilization plays a significant role in the growth of your Zelkova bonsai.

  1. Apply fertilizer from spring to autumn to provide essential nutrients.
  2. Use a balanced fertilizer suitable for bonsai to promote healthy growth.
Step 3: Pruning

Pruning is essential for maintaining the shape and health of your bonsai.

  2. Remove any dead or unwanted branches to improve air circulation and light penetration.
Step 4: Pinching

Pinching helps control the growth and shape of new branches.

  1. During the growing season, when new branches have 6 to 8 pairs of leaves, use tweezers to pinch off 2 pairs.
  2. This encourages denser foliage and a more compact shape.
Step 5: Wiring

Wiring is a technique used to shape the branches of your bonsai.

  1. Start wiring your Zelkova bonsai from spring to autumn when the branches are pliable.
  2. Carefully wrap the wire around the branches, being cautious not to damage the bark.
Step 6: Re-potting

Re-potting is necessary to promote healthy root growth.

  1. Re-pot your Zelkova bonsai every two years when it begins to blossom.
  2. Use a substrate of 100% Akadama or a mix with 20% volcanic clay for optimal drainage.

  1. Keep your bonsai in direct sunlight throughout the year, especially in Mediterranean climates.

Identifying and addressing common problems can help maintain your bonsai's health.

  1. If your Zelkova bonsai is losing leaves, it may be due to over-watering or sudden temperature changes; adjust your care accordingly.
  2. Yellowing leaves could indicate nutrient deficiency; ensure a balanced fertilization routine is followed.
