cant go far wrong following the info

your welcome VT

Advice from the Citrus Centre where i got mine was spring to autumn feed citrus food each time you feed, and stop during winter, i put mine in a wood cabin about two feet from a window throughout the winter, they don't like frost. During the summer it lives on the patio,
Last year due to the weather it doubled in height.

When harvesting take the leaf stem, cutting back will stimulate growth, their is a stack of stuff on youtube.

good luck

Follow Phil's advice, also if its living in a greenhouse as you say mist the leaves every day, it will help keep spider mite and scale insect at bay.

I did find cutting the first branch after nurturing it hard esp considering there wasn't a lot on it, you have to have the mindset that to cut it back will induce more growth.
On a positive note my plant doubled its height last year purely i think because of the good weather we had. I feel outside is better for them,

Garp its a good reference point to look back to and see how far along the BIR path one has travelled.

They like Epsom Salts too, is it sprouting yet?

Thanks for the Laugh Phil, my experience of curry then was curry powder into a pot with beef, pinapple chunks and sultanas, dumped onto a pile of rice, thanks mum.
