Longan Soil Mix

Lychee's cousin, with the same low-pH appetite.

Why Longan Needs its own Blend

Longan shares lychee's preference for acid, well-drained ground. This blend is sulfur-adjusted to hold a lower pH, drains hard through cinder, and supplies the broad trace minerals longan draws on through its long establishment.

What the Blend does for the Plant

  • Line-art icon of a healthy seedling with a strong root system, representing sustainable growth in organic Hawaiian volcanic soil.

    Holds the Low pH

    Elemental sulfur in place of lime keeps the root zone in the acid range these crops want.

  • Icon illustrating iron (Fe) nutrient supplementation for healthy crops grown in organic Hawaiian volcanic soil at our farm.

    Keeps Iron Available

    At lower pH, iron and magnesium stay available so leaves hold their color.

  • Young seedling sprouting in nutrient-rich organic Hawaiian volcanic soil.

    Drains for the Wet Side

    Black cinder keeps windward ground from staying saturated around young roots.

  • Builds biology Icon

    Builds Biology

    Compost and mycorrhizae widen the root system's reach as the plant establishes.

Planting Tips: Acid-Loving Fruit Trees

  1. Plant High and Drained: Choose a well-drained spot or mound. These trees establish slowly and rot easily in wet ground.
  2. Shelter Young Trees: Lychee, longan, and coffee are tender when young. Give some wind shelter and afternoon shade the first year.
  3. Keep the pH Low: Do not lime around these trees. If leaves yellow between the veins, the pH may be drifting up.
  4. Mulch, off the Trunk: Mulch out to the drip line to hold moisture and feed biology, kept a hand's width off the trunk.
  5. Be Patient with Fruiting: Lychee and longan can take years to bear. Steady soil and even moisture beat pushing them hard.
