Community Gardening in April 2013
April is great, the soil is warming up and spring should be
here. Do keep an eye on the weather forecast though, even in Ireland we can still get cold snaps and snow
is not unknown in April. Keeping
horticultural fleece on standby in case of cold weather is a good idea.
Harvest: We're in
the 'Hungry Gap' between the last of the winter crops and start of the early
crops but there are still a few things available, late sprouting and chards for
example plus you may have some early salad crops from the greenhouse border.
General Gardening Tip:
If you have any horticultural fleece, you can peg that onto the ground a
week or so before you plant. The small rise in temperature of the soil can make
a big difference
Sowing, Planting and
Cultivating: There's quite a list to
sow and plant outside, especially if March has not been suitable.
Do remember the weeds are springing into action, so keep the
hoe going. Don't forget, a sharp hoe is the best friend a gardener can have.
Just slide it back and forth slightly below the surface of the soil and you'll
stop the weed seedlings in their tracks. Hoeing is also good in the event of
drought as the disturbed soil surface stops the water being sucked to the
surface by capillary action and evaporating in dry winds.
Things to Sow: •Beetroot
•Peas •Broad Beans •Broccoli
•Brussels Sprouts •Cabbage •Cauliflower •Kale
•Chard •Kohl Rabi •Leeks
•Spinach •Beet spinach •Rocket
•Lettuce •Radish
With your carrots, covering with a fleece and ensuring the
edges are buried will stop the carrot root fly from gaining entry to lay eggs
by your carrots. The eggs hatch in larvae that burrow into the carrot root,
killing the plant or at least ruining the crop.
Plant Outdoors: Globe
and Jerusalem Artichokes Onion &
Shallot Sets Asparagus.
March is the traditional potato planting time. If you have a
comfrey bed and it has sprung back, the first cut laid in the trench under the
potatoes will provide nutrition to get them off to a good start.
On the subject of
comfrey, if you make a comfrey tea it will help you to a great crop to use it
on your potatoes. Many novice growers wonder why they have small crops of
potatoes and most often this is just down to lack of food for this hungry crop.
Sow in Heat (Greenhouse or Windowsill)
•Aubergine •Celery
•Outdoor Cucumbers •Tomatoes (if
you've not already done so) A good tip
in a windowsill is to stick some silver cooking foil onto cardboard and place
on the inside to reflect light back onto the seedlings. This will help revent
them being drawn.
Sow Outdoors Under
Cloche: •French beans •Lettuce
•Sweetcorn
Alternative Method for Sweetcorn like to pre-chit sweetcorn, lay the seeds on a layer of damp
kitchen paper and then place a layer of paper over in an airtight box. An old
ice-cream carton or a Tupperware type box is ideal. Check carefully each day
and as soon as the small white sprout appears, plant the seed about half to an
inch deep in a 7.5cm(3") pot of general purpose compost in the greenhouse.
When the shoots appear about an 2.5cm (inch) high, plant out under cloche being
careful not to disturb the root (sweetcorn hates root disturbance) under a
cloche. Sweetcorn needs a lot of nitrogen and a teaspoon of dried blood per
plant or water with urea (this is a chemical, I do not mean pee on them!)
Many of the crops you can sow directly will also benefit
from cloching, especially as you move northwards or started off in modules in a
cool greenhouse or coldframe and then planted out later.
Fruit: Strawberries
can be planted out now, it's best to remove flowers in the first year as you
conserve strength for growth and gain larger crops in subsequent years. An easy
way to gain strawberry plants is to plant the runners into pots and when rooted
cut the runner. The plants don't last forever so you need to rotate them ever
three to five years.
Hand pollinate peaches and nectarines. Tickle the flowers
with a small paint brush to spread the pollen. Cover if a cold spell threatens.
A good layer of compost around the base of fruit trees will ensure they have
the nutrition to provide another good crop for you.
Gardener's Pests: I've
mentioned the carrot root fly but the gardener's worst enemy is awakening. The
evil slugs and snails are coming out to eat entire rows of succulent young
seedlings overnight so take action now
