WORKING WITH THE WEATHER
Great year for outdoor figs |
Gardeners just love
the challenge of growing something better than normal, whether it be a huge
pumpkin, a massive potato, a dazzling show of flowers, or a brilliant fruit
crop. We study the techniques for growing each plant, water them, feed them,
prune them, spray them for pests and diseases and keep them free from weeds.
Success however is still dependant on the weather being in
our favour. We never
seem to get two years the same, so we must monitor the weather forecasts and work
within its limits. I like to try and get all my allotment digging done at the
beginning of winter, but last year autumn was wet and continued well into
December so digging was delayed. Then the rain stopped, the ground surface
dried up and winter never arrived till February, so I spent January on the plot
and got the lot dug over leaving the surface rough for winter weathering.
Outdoor grape Brant |
Climate change is
very debatable, but we can all remember the unusual years of hot dry summers
like last year, then 1976 and 1959 (for us old enough to remember.) In 1976 I
was in Darlington where we grew thousands of geraniums which put on a fantastic
show of colour helping us to win the regional Britain in Bloom award. Working
in horticulture outdoors you can remember many very bad winters. I don’t
remember 1947 (I was only 3 years old) but I do remember 1962/63 cycling
through deep snow to get to work. In 1981/82 I had come north from Darlington to
Dundee for a Christmas holiday, but before I could return blizzards closed all
the roads. There was no trains, no buses so no-one could get to work, but there
were several well trodden tracks through the deep snow heading towards the Nine
Maidens pub, which we discovered was packed. Then 2010/11 winter
returned and blocked
off all the roads again, and killed off to ground level all my fuchsias and a
ten foot tall Cordyline australis. Severe winters are not frequent, but dry hot
summers seem to be coming in more regularly, so I am happy to try growing some
of the more exotic plants to see if I can succeed with them. I grow several
grape varieties outdoors as well as peaches, cherries and figs, but they all
need a warm dry autumn to help ripening. The challenge also exists with
strawberries where it is possible to get the first berries ripe towards the end
of May using low polythene tunnels, an early variety and a warm spring.
Cropping then continues with maincrops, late varieties then autumn fruiting
types. However they still need warmth to ripen up so a good autumn really
helps.
Pansies in January |
Planting first early potato Casablanca |
Last year the mild
winter continued well into spring so tulips had a fantastic display in the cool
climate, but other plants were running three weeks late with the lack of any
warm spring weather. However the long hot summer reversed this trend so we
ended up three weeks ahead by the end of summer. This year the mild winter
allowed me to pick a large bunch of red roses for the Christmas table and my
winter pansies were showing flowers from early January.
Early potatoes can
give the first spuds by the end of May if with a good spring, planting them in
March and hoping there is no late frost. Earth then up to protect them if frost
is forecast.
Wind can be a
problem for any young or tender plants in spring, or ripening crops in late
summer and autumn, so if the garden is very exposed plant a narrow hedge or
erect a fence as a windbreak.
Pests and diseases
infestations are also very weather dependant. A bad winter kills off many pests
including slugs and disease spores. Last year the summer was so dry that potato
blight never arrived till late summer, and rose diseases were not a problem
till late in the season. I never forget the greenfly plague in 1975 starting in
Lincolnshire and extending up to the Scottish borders, followed by the ladybird
plague of 1976. Ladybirds feed on greenfly.
Amaryllis |
Wee jobs to do this week
Amaryllis that were
started back into growth last October are now in full bloom and a light liquid
feed every two to three weeks will help to build up strength in the bulb. Once
the flowers start to fade the leaves and roots still need feeding throughout
the summer. They can go outdoors in summer in a sheltered sunny spot, but keep
them watered and fed. However usually in mid summer withhold watering for about
ten weeks and let the bulbs dry off to ripen them up. As they go dormant next
years flower buds will be forming in the bulb.
