The Best Bonsai Fertiliser: Slow-Release vs Liquid

Feeding method matters less than feeding consistently — but slow-release and liquid feeds suit different habits, and one species on this site (ficus) has a feed genuinely worth buying species-matched.

Our picks

  1. Omakase Slow-Release Bonsai Fertiliser, 700g — 700g
    Soil & Feed 700g

    1. Omakase Slow-Release Bonsai Fertiliser, 700g

    The lowest-effort option — pellets on the soil surface release nutrients gradually, no weekly routine required.

  2. Organic Bonsai Food — Liquid Fertiliser, 1L — 1L
    Soil & Feed 1L

    2. Organic Bonsai Food — Liquid Fertiliser, 1L

    Faster-acting and easier to dial back if a tree is stressed or freshly repotted, at the cost of needing a regular feeding routine.

  3. GREEN24 Ficus Bonsai Liquid Fertiliser (Ginseng, Retusa, Microcarpa) — Concentrate, mix to use
    Ficus Bonsai Concentrate, mix to use

    3. GREEN24 Ficus Bonsai Liquid Fertiliser (Ginseng, Retusa, Microcarpa)

    Worth the switch specifically if you're growing one of our ficus varieties — formulated for ficus rather than a general bonsai blend.

  4. Bonsai Soil — All-Purpose Fast-Draining Mix — 2 quart bag
    Soil & Feed 2 quart bag

    4. Bonsai Soil — All-Purpose Fast-Draining Mix

    Not a feed, but the other half of nutrition — ordinary compost holds too much water for a bonsai's shallow pot, and a proper free-draining mix is a common upgrade after a tree struggles.
