EXTEND THE GROWING SEASON FOR FRUIT AND VEGETABLES
Allotment
gardeners traditionally always get a glut of some crop that we share with
fellow plot holders, family and friends. Some crops such as courgettes, Swedes,
cabbages and potatoes, plums and apples can all have a prolific year if the weather
is kind. We also tend to grow too much of each crop just in case we get losses.
However I am now tending to grow smaller rows and a wider range of fruit and
vegetables so I get less surplus and have fresh produce available over a longer
period. This idea can be extended further by using the protection of
greenhouses, frames and polythene tunnels for bringing on crops earlier and
extending the season into the autumn.
It is
just about possible to be self sufficient in fruit and vegetables harvested
from your own garden provided you accept each crop has its own season. The most
difficult period is March and April when the previous years stored crops are
just about done and the current year’s crops are still growing. This is when
the freezer helps us out as most crops can be frozen and kept in good order for
months. The summer and autumn months are the easy ones when there is plenty
available and surplus can be stored. Winter is also not too difficult as there
is a wide range of winter hardy crops such as Swedes, Sprouts, cabbage, leeks,
parsnips, kale, Swiss chard and if you are lucky late sown, (August) summer
salads such as spring onion, rocket, sorrel, corn salad and mustard mix can see
you in fresh leaves till the end of January as they can tolerate a wee bit of
frost. My outdoor beetroot has now finished but onions and pumpkins will stay
fresh for a few more months.
Salads and vegetables
Ground
prepared well in advance can be covered with low polythene tunnels in mid March
to warm up for a few weeks before planting out an early batch of lettuce,
spring onions, radish, beetroot and carrots. These are sown in cellular plug
trays also in mid march for planting out about four weeks later. The radish are
always ready first then lettuce can be picked when quite small as there is
usually plenty to grow on a bit bigger. If poly tunnels are not available a
cold frame is just as good as long as the soil is well prepared.
Cabbage
and cauliflower can also be harvested just about all year round by selecting
varieties suited to each season. My spring cabbage can be cut in April and May
as spring greens then other plants left to heart up. However these are often
overtaken by my early summer cabbage sown in the greenhouse for early planting.
Later on we pick the autumn cabbage, then the winter cabbage takes us just
about to March, provided clubroot and other pests don’t spoil your plans.
Cauliflower can be grown all year round in a similar way, though there is
usually a gap in mid winter.
Fruit crops
To grow
raspberries and strawberries outside their normal summer season you need to
look to the methods of the commercial growers. If you have the room in a
glasshouse a couple of pots of an early raspberry variety are a luxury to sample
fresh ripe rasps two to three weeks ahead of the early outdoor crops. However
extending the season into autumn is normal now with Autumn Bliss and other
autumn fruiting rasps. These will fruit till the end of November, but may not
be very sweet as they need the warmth of sunshine for best results.
Strawberries
can be grown under low polythene tunnels erected at the end of February over a
young row planted up the previous autumn. I use the early variety Mae which
never lets me down. I also extend the season into autumn with the perpetual
variety Flamenco which will continue to fruit till November, but also needs
sunshine. Flamenco will fruit from new runners throughout the season.
The
summer blueberry season comes in August but saskatoons which are very similar
fruit in July so giving almost two months of very healthy fresh black fruits.
The apple
season gets extended by grafting early and late varieties onto my one large
tree, so the Oslin fruits in August, followed by Discovery in September. Red
Falstaff and Red Devil are ready in October but can be stored for a couple of
months, then Fiesta, my late variety will store to the end of the year.
Outdoor
grapes fruit in September to October in a normal year, but in the greenhouse my
Flame starts in August followed by Perlette then Black Hamburg will last till
December.
Plant of the week
Wintersweet, Chimonanthus praecox can be a beautiful winter
flowering shrub with yellow spicy scented flowers, but it needs a sunny
sheltered spot with good soil and drainage. Planted at the base of a south
facing wall with plenty of organic matter added to the soil at planting, then
given a mulch so it doesn’t dry out just in case we get a dry year. It is
deciduous so the flowers emerging in November and lasting in some years till
March can be easily seen. This hardy shrub from the mountains of China can grow
up to ten foot tall but careful pruning can keep it about six feet if
preferred. The main disadvantage for the impatient gardener is that it takes
about four or more years to settle down before it starts to flower. This is
another reason why propagation is best by layering rather than from seed as the
latter could take a very long time to reach maturity for flowering. Leave
layered shoots at least two years to grow decent roots before digging up.
