GIY: Planting Seedlings


I am doing a lot of transplanting at the moment, which is always a fun activity for a GIYer.  There’s nothing like the satisfaction of planting seedlings – bare beds transformed in an instant with neat rows of little plants.  I always feel intensely happy after spending some time planting – and now I know that there is actually a scientific reason for this – contact with soil triggers the release of serotonin in our brain according to research. Serotonin is the happy chemical – it is a natural anti-depressant and strengthens the immune system.  

On the other hand, there are always a few days of fretting after transplanting – will cold nights set the plants back? Will slugs or rabbits try and munch on them?

Seed sowing is a relatively exact science – if you sow a seed at the right temperature and at the right depth, and you keep the potting compost moist, then it will generally germinate rather reliably.  In addition, up to the point that they are transplanted, the seedlings have luxuriated in the 5-star comfort of my potting shed. They have been nurtured, spoiled, cossetted.

I’ve carefully watered them each day, switched on heat underneath them at night and covered them with fleece. The potting shed is a controlled environment – there is no weather in there – no rain or wind.  Nor are there any pests to trouble them – leather jackets, slugs, snails, birds or rabbits.

Planting a seedling out in the soil therefore is a watershed moment.  It is the moment it leaves a very controlled environment in favour of something far more uncontrolled, unpredictable and messy.  And like a parent sending a child off to school for the first time, you just have to have faith and let it go in to the mad, bad world!!

Things to do in June


  • Watering and weeding duties step up a notch – the tunnel/greenhouse in particular will require a good deal of water from now on.
  • Watch the weather and water outside as required.
  • Continue to earth-up potato plants to prevent the spuds becoming green.
  • Mulch and water tomato plants and continue to remove side shoots that appear in the leaf axils.
  • Stake everything that grows tall – raspberries, peas, beans, tomatoes etc.
  • Net soft fruit against birds – it’s worth the effort.


  • Sow courgettes, pumpkins, summer and winter squash, fennel, chicory.
  • Succession sow: beans (French and Runner), kale, pea, spinach, spinach beet, summer broccoli, carrot, swede, leek, lettuce, Brussels sprouts, beetroot, chicory, endive, turnip, kohlrabi, fennel.
  • Plant out leeks, Brussels Sprouts, cabbage, autumn cauliflower, calabrese, sprouting broccoli, celery, celeriac, cucumbers, pumpkin,  marrows, runner beans, aubergine.


  • We are now really starting to see some payback from our GIYing – the first broad beans and peas as well as new potatoes, new carrots, soft fruit like gooseberries, cherries and strawberries.
  • Herbs are in full flow.
  • Also harvest kohlrabi, cabbage, cauliflower (month end), spinach, spring onion, shallots, salad leaves, elderflower, rhubarb, salad leaves, onions, carrots, beetroot, garlic, sea-kale.

Tip of the Month – Manually pollinating courgette plants

In cold or very wet summers, you may notice that fruit is not forming well on your courgette plants.  This can be because pollination is poor (lack of insects to move the pollen from the male to female plant).

The problem can be fixed by getting all Charles Darwin and pollinating the plants manually.  Remove a male flower from the plant and brush the central parts against the centre of a female flower (the pollen from the male plant is rubbed against the stigma of the female plant).  The female flowers are the ones that have a small fruit starting to form behind them.  The male flowers don’t.
