We have a 3 foot x 2 foot dia ceramic pot that is crying our for a Lemon tree that we can nurture on in our fruit area on the plot,I have seen trees from about £30 to £60 here and there but dont know a suitable hardy variety that can cope with our mixed seasonal weather.
I have some citrus, a couple of which I have managed to keep alive for about 15 years now. The things they don't seem to like, and which will make them drop their leaves are overwatering when they are not needing so much water ie spring winter, and quick changes in temperature at any time of year.
I recently read they are better if watered via matting, but haven't tried that yet. What I try to do is leave it until the leaves just begin to almost wilt a bit, then give a nice thorough watering, but don't leave water standing in the plant saucer.
Also liquid seaweed fertilizer seems good as a watering or leaf spraying fertilizer
They will stand a couple of degrees of frost, but not real solid freezing.
Often the leaves will fall off completely, but as long as you don't overwater at this critical point they will come back. I bought a lemon tree with no leaves at all from a garden centre for £5 and it is fine now.
found that reply in the archive that talks of the growing but doesnt mention a variety.
any worthwhile suggestions.
