Well, our little tree has suddenly started to thrive!

It is growing fast with loads of new leaves, and has at least a dozen
flowers.
Some are open others are about to open.

It must be the hot weather fooling it into thinking it is in the Med.

It is also getting watered daily early in the morning, as it is on a south
facing patio.

Perhaps we may even have a few lemons?

My only problem now is that it is in a small pot.
I planned to pot it up around now into a much bigger pot, but I am
reluctant
to disturb it whilst it is flowering.

I may do this in a cool spell later on in the month, depending on how it
seems to be coping with the little pot.

Glad to hear it. Lemons (and Tahiti Limes) are good value and fruit well
with good usable fruit.

The one thing citrus can't stand is wet at the roots especially if it's
anything but hot, so don't water daily unless it is very hot, just moist is
OK but never wet. A few cold nights and rain and you may have a problem
again.
If your plant is flowering then it sounds OK and doesn't need repotting yet,
just feed every couple of weeks. When you do repot use a slightly bigger pot
each time don't go from one extreme to another.
When you do repot, if you are in a hard water area, use ericaceous compost,
whatever compost you use add grit or bark chips (as used by orchid growers)
to aid drainage.
Lemons take at least 6 months to a year to grow and ripen the fruit so, like
us, you may have some for next Christmas & New Year. A G&T and/or cake made
with your own lemons is special.
As the tree gets older they tend to flower/fruit at any time of the year,
one of ours has a few fruit well on the way to full size and has just burst
into flower again ( the Tahiti Lime is the same).
