Earlier quoted context omitted.
with regards to the olives, are you using water or brine to treat them?
neither - the two trees I have don’t produce more than a handful of fruit, so they are mainly ornamental. I don’t think the growing season is long enough for the olives to grow to a reasonable size

> Citrus (lemon, lime and kafir lime) - Any frost is damaging, can only grow in pots and bring in during winter. Grows slowly and doesn't produce much fruit Lime and kafir lime are very tender. If lemons do not work, I would suggest you to choose hardy rootstocks (Poncirus can stand -40C for a short time) and try Yuzu instead. They are seedy, spiny (as lemons or limes), and less interesting as fruit but more hardy. T…
Stauntonia - it's an evergreen vine, with fleshy leaves, originally from Myanmar/Korea/Japan. In Japan I think they eat both young shoots and the sausage shaped fruit.
