In the garden

Like citranges: full sun and well-drained soil. Use its fruit like a lime, in cooking and in cocktails.

The plant you receive

You receive a young grafted tree about 40 cm tall above the pot, low-grafted onto a Poncirus trifoliata rootstock from our own production. Planted young, it roots straight into your garden soil and establishes better than a tree kept in a pot for years.

Because it is grafted low, the variety itself forms the trunk: the tree stands on its own without a stake and can regrow from above the graft after a severe frost. All our citrus trees are grown at 1,000 m altitude in the Livradois, never in a heated greenhouse, with organic fertiliser only.

Grafted trees are shipped from June; the rest of the year, you can pre-order them.
