Lime taboos in tea: how to correct acid without hurting the bush

Don’t push tea to neutrality.

Acid soil
Speed
  1. Tea shoots short, leaves small; someone copied grain lime and it yellowed more.
  2. Tea’s window is about 4.5–6.0.
  3. A grain-land rate does not move into a tea garden.
  4. The too-acid tea guide is the one that asks whether to lift pH. This page is only the don’ts.
  5. Don’t start at 150 kg/mu like grain; don’t push tea to pH 7; don’t throw lime on the collar.
  6. Tea garden default: Not the grain-land lime table. If you truly must lift tea-garden pH, only the tiny rate in the too-acid tea guide
  7. Name what you see before you feed.
  8. If leaves, roots and the surface disagree, stop.

What you see in the field

Tea shoots short, leaves small; someone copied grain lime and it yellowed more. Tea’s window is about 4.5–6.0.Walk the worst strip. Pull one plant, rinse the roots at the ditch without rubbing the tips, and read white tips versus brown bald ones. A rusty film on water is extra, not required. Grain land and tea do not share a pH target.

A sketch. Do not fertilise from the picture alone.

Why it looks like this

The field looks like this because the root cannot take water or nutrients the usual way. Fix the soil condition first — drainage, salt, acidity, compaction or a salt of fertiliser — then a thin feed. Rates live in the range on this page; confirm with a local station and the label.

Easy to mix up

  • Looks like “A grain-field lime rate”

    A grain-land rate does not move into a tea garden.

  • Looks like “A tea garden that is too acid and needs a little lift”

    The too-acid tea guide is the one that asks whether to lift pH. This page is only the don’ts.

Do this / don’t do that

  1. 1Compare the worst plants with a neighbour ridge. Photograph whole plant, close-up and soil surface before you add fertiliser.
  2. 2Match roots, leaves and the soil surface to this guide. If they do not line up, do not copy a bag count.
  3. 3Use the rate range on this page only as a range. Confirm with a local station and the product label.

Don’t do this first

  • Don’t start at 150 kg/mu like grain; don’t push tea to pH 7; don’t throw lime on the collar.

Rate range

Tea garden default

Not the grain-land lime table

If you truly must lift tea-garden pH, only the tiny rate in the too-acid tea guide.

These are ranges. Confirm with your local extension station and the product label.

pH

A tea garden’s own

Don’t use a grain-land target.

When you see Tea shoots short, test. Mix several spots of the tilled layer; skip the edge and the manure heap.
