tropical plants over winter months
 

Can anyone offer advice & help on growing tropical plants indoors in the UK,
perhaps a website for me to look for answers etc.

I have a small variety of tropical plants (Thai limes, lemon grass,
ginger/galangal, pandanus etc.) that i grow for my kitchen. I put them out
every summer & they thrive but when i bring them in for autumn & winter,
they suffer. I've just had to strip back the pandanus because it seems to be
dying, lots of brown leaves & white tiny fluffy cotton wool like things with
white mite like creatures multiplying where the leaves grow out from the
stem. Can someone please tell me what these white fluffy things are & a cure
for it. It's impossible to clean & wipe off as the leaves grow directly off
the stem & this is where it conregates. Maybe some solution can be poured
down the spaces between the leaves & stem to kill the mites?

Also advice on general plant care during the winter months. The best i've
done so far is to warp a large clear plastic bag over each plant, creating a
micro-climate inside but this is always susceptible to all sorts of fungal
growth. I've placed the plants next to the kitchen window but it seems still
too cold for them & anywhere else in the house it seems not too happy
because of the lack of sunlight & humidity. Any suggestions? we do not have
a green house or conservatory. The kitchen is the warmest room in the house
although not humid enough it seems.

Sounds like mealybug, and you may well have red spider mite. Spray
the plants hard (soak them, especially in the crevices for mealybug
and under the leaves for RSM) with a soft soap solution or a washing
up liquid solution with a squirt of meths in it. Do that as often
as the symptoms appear - and look up red spider mite on the net.
You may find that scrubbing gently with a soft toothbrush wet with
the solution helps with mealybug.

I use Savona (a proprietary soft soap), but it isn't critical.

For citrus and similar plants, that is precisely wrong. They don't
mind a bit of cold, and should be kept somewhere light and cool,
with plenty of ventilation to avoid fungal problems. They DON'T
need high humidity, and don't like it, especially when cool or
dark. Even the true humid tropical plants won't like being in a
plastic bag.
