Plant your greenhouse bulbs<br />
a little earlier than you would<br />
those grown in the garden.<br />
Choose colourful pots as these,<br />
too, will add colour to your<br />
home in winter.<br />
Avoid unglazed terracotta pots<br />
where possible as these porous<br />
containers allow the soil to dry<br />
out too quickly. Some of the best<br />
pots for greenhouse-grown bulbs<br />
are those that have no holes in<br />
the base but, instead, have a<br />
raised, self-draining platform<br />
built into the container. Using<br />
these pots means you won’t have<br />
to provide a drip tray when they<br />
are eventually placed on the<br />
window ledge.<br />
Choose a quality bulb mix.<br />
Homemade compost is an option<br />
but, as it is not sterilised, you<br />
may introduce disease into the<br />
bulbs – something you don’t<br />
want to do when you are aiming<br />
for perfect blooms to bring<br />
indoors. Maximise the space in<br />
pots by planting bulbs in two<br />
layers – the shoots of the under<br />
layer of bulbs will find their own<br />
way up to the light and once the<br />
bulbs are in flower, the pot will<br />
be brimming over with colour.<br />
After planting, store the<br />
containers of bulbs in a shady<br />
spot, such as a garden shed<br />
or underneath greenhouse<br />
shelves. This helps the bulbs<br />
form strong roots before they<br />
begin putting their energy into<br />
foliage. Once the green shoots<br />
are 1–2cm high, move the pots<br />
into the light and, if they have<br />
been in a shed, transfer them to<br />
the greenhouse. Taller plants,<br />
such as daffodils and tulips, will<br />
soon require staking. Use thin<br />
supports for this as they can fit<br />
easily down the side of the pots<br />
(chopsticks are ideal). If foliage is<br />
particularly lanky (as is often the<br />
case with freesias) wind thread<br />
(black is best as it is unobtrusive)<br />
between the supports to help<br />
hold up leaves.<br />
As soon as buds show, it’s time<br />
to bring your flowering bulbs<br />
indoors to enjoy the pleasure<br />
of watching them open. As the<br />
plants are now in the heat of the<br />
house, you will need to water<br />
them more frequently – but<br />
never allow the potting mix to<br />
become wet.<br />
Tend your treasures carefully<br />
to keep them looking their<br />
best: snip off yellowing leaves<br />
and spent flowers and keep<br />
a watchful eye out for overwintering<br />
aphids, which may<br />
suddenly spring into life in the<br />
warmth of your home. If they do<br />
make an appearance, treat them<br />
with a spray of soapy water (1<br />
teaspoon of hand soap dissolved<br />
in a litre of hot water).<br />
VERSATILE: (Clockwise from top left) – Rosemary detests wet feet and even mature bushes<br />
can be lost over winter. Enjoy the fragrance of its pungent oils by growing a bush or two in the<br />
greenhouse; Even though herbs are growing in the greenhouse, they won’t produce as they would<br />
if outdoors over summer – so be sure to plant plenty; If you are not concerned with a second year<br />
of flowering, bulbs can be grown in the greenhouse in very little soil; Create a pot brimming over<br />
with colour by planting a double layer of bulbs; Once the bulbs are planted, keep them in a shady<br />
spot until the shoots make an appearance – this encourages strong root development.<br />
