March Gardening Newsletter

Posted by on Mar 21, 2017 in Newsletters

Dear Fellow Gardeners,

March is really the beginning of the gardening year but please don’t be impatient. I suppose the weather this March isn’t conducive to gardening yet. Let’s hope there is some change on the way.  It’s actually wetter now than it was throughout the winter.

There is still plenty of time to sow your crops.  In this newsletter you’ll find a detailed guide on what to do in your garden and polytunnel in March.

First here are a few dates for your diary:

Sun. 12th March 2017 Potato Day at the Organic Centre in Leitrim –

There will be an update on our potato breeding experiment and potato seedlings of NEW varieties will be available.

Mon. 20th March 2017             Film: “Symphony of the Soil” and Discussion

This is an amazing and fascinating documentary about soils – its wonders as well as the dangers that it faces.  I will give a short introduction and we’ll hopefully get quite a few people to sign the People4Soil petition.

Entrance is free-

More details to follow in the next newsletter.

 

Onion Sets available now:

We now have maincrop onion sets available in stock.  It’s a fabulous variety (Stur BC 20) which is very disease resistant and produces wonderful round onions that dry and store extremely well.

If you had problems growing and storing onions before – try these ones.  Stock is limited.

 

March – what to do in the garden?

Don’t be misled by the nice spells of weather we often get in March.  Apart from the few vegetables listed below there is nothing you can sow or plant outdoors.   Continue preparing beds if there is a dry spell.  Rake over the beds you have prepared last month to get rid of weed seedlings.  You should also check your stored vegetables for any signs of rot.

Sowing

Around the middle of the month you can plant your early potatoes, onion and shallot sets.  To protect your onion and shallot sets from birds you can cover them with bird netting over wire hoops or alternatively cover with a cloche covered in bionet.   Sow indoors in a tunnel or windowsill: leeks, early cabbage, scallions, celery and celeriac. If you haven’t sown broad beans yet there is still time.   Jerusalem artichokes and garlic can also still be planted.

Harvesting

Harvest outdoors: Jerusalem artichokes, parsnips, leeks, kale and possibly perpetual spinach which is re-sprouting again.  All these crops are slowly coming to an end now so you should use them up quickly if you have many of them left.  You will soon get your first picking of purple sprouting broccoli this month. Use stored vegetables: potatoes, beetroot, Dutch cabbage, carrots, onions, shallots and swedes.

 

March – What to do in your polytunnel or greenhouse?

You will really feel the warmth in your greenhouse or polytunnel now and so do your plants.  They start to grow quite rapidly now but be aware that the nights are still quite cold and there is still a high risk of frost.  Many garden centres will try and sell you tomato plants from the end of March onwards.  Don’t let them tempt you until May.

Sowing

Direct sowing into beds:

In March you can still sow the following vegetables directly into the soil.  Beetroot (Pablo F1), Carrots (Rocket F1) French beans (dwarf and climbing types) Peas, Mangetout (Sweet Horizon) Radish (Cherry Belle) – small amounts at regular intervals Turnips (Milan Purple Top) – small amounts at regular intervals

However, if you sow carrots, beetroot and peas now they will only be ready in mid June which is far too late to plant your tomatoes or peppers.

Planting into beds

You can now plant out the seedlings you raised earlier on your heating bench: lettuce, scallions, dill, coriander, chervil, early cabbage, calabrese, mini-cauliflowers, early leeks, perpetual spinach, Swiss chard, salad rocket and all other oriental salads.  Most seedlings take about 4-5 weeks from sowing until they are ready to plant.

Sowing into modules/pots (18-20˚C)

Do not let your heating bench clutter up too much.  Most vegetables only require some warmth for germination and in March the seedlings are better off if placed on a non-heated bench in the tunnel or greenhouse.  Only your tomatoes, peppers, chillies, aubergines, courgettes, cucumbers, squash, pumpkins, celery, celeriac and basil should remain on the heating bench until they are    planted in May.  Really all other vegetables should be moved off the heating bench about a week after they have germinated.  In March you can sow the following vegetables into modular trays and place them in your   propagator or warm, south-facing windowsill in the house:

Aubergine (Black Beauty F1) – 5 seeds per 7cm pot, for pricking out

Basil (Sweet Genovese) – 4 seeds per cell  (only late in the month)

Calabrese (Chevalier F1) – 1 seed per cell

Cauliflower (for mini cauliflowers) – 1 seed per cell

Celery (Victoria F1) – broadcast in a tray for pricking out later

Chilli peppers (Ring of Fire) – 5 seeds per 7cm pot –  early in the month

Courgette (Defender F1 and Parador F1 – yellow) – 1 seed per 7cm pot

Coriander, Dill and Chervil – 5 seeds per cell

French beans (climbing and dwarf) – 5 seeds per 9cm pot

Kohlrabi (Azur Star) – 1 seed per cell

Lettuce (various types) – 1 to 3 seeds per cell

Oriental salads (mizuna, rocket, tatsoi, etc.) – 5 seeds per cell

Pepper (Roberta F1, Bell Boy F1) – 5 seeds per 7cm pot, for pricking out

Scallions (Ishikura Bunching) – 5 to 10 seeds per cell,

Tomato (Sungold F1 & others) – 5 seeds per 7cm pot, for pricking out.

 

Do not sow your cucumbers and melons yet.  You’ll get much better results if you wait until April to sow them.

For planting outside

You can also raise the following vegetables indoors for planting out into your vegetable garden later.

Cabbage (early varieties) – 1 seed per cell

Calabrese (Chevalier F1) – 1 seed per cell

Celery (Victoria F1) – broadcast in a tray for pricking out later

Celeriac (Giant Prague) –      broadcast in a tray for pricking out later

Kohlrabi (Azur Star) – 1 seed per cell Leeks (Hannibal) – 2 seeds per cell

Lettuce (various) – 1 to 3 cells per cell

Onions (Golden Bear F1) – 4 seeds per cell

Scallions (Ishikura Bunching) – 10 seeds per cell

 

Harvesting

Salad rocket, wild rocket, various mustard leaves (Green Wave, Green in the snow, Red Frills, Green Frills), tatsoi, pak choi, corn salad, winter purslane, cress, mizuna, mibuna, komatsuna, texel greens, baby spinach, beet leaves (Bulls Blood) and possibly even some lettuce leaves.   You can still harvest the overwintered Swiss chard and perpetual spinach and towards the end of the month you should get your first radishes and baby turnips.

 

Protect our soils  – People 4 Soil

Update of People 4 Soil Campaign:  We have reached 17% of required signatures for Ireland.  The information on the link is from the European organisers of the campaign to protect our soils.  May I ask you all again – please sign this very important petition and share it with friends and on social media.  Without soils there will be no life on Earth as we know it.

Please support the People4Soil Campaign:

 

Please support the People4Soil Campaign: There’s a part of our world that is crucial to all life on our planet, but one we don’t think about very often – soil. Soil is a precious resource that feeds the planet but is under constant threat from industry, over-farming, pesticides, urbanisation and the loss of biodiversity. Despite its huge importance, incredibly there is still no common law in Europe that protects our soil. Safeguarding soil is necessary to protect people, plants, and animals. In short, all life depends on healthy soil. Without soil, there is no future. We, the citizens of Europe, ask the European Union to protect soil from cement, from pollution, and from speculative interests. With us, more than 400 associations from all over Europe make up the “People 4 Soil” coalition. We demand the European Union to protect soil by using a European Citizens initiative, the official EU tool for citizens to call for new laws. It requires more information from you than a normal petition because of the strict rules laid down by the EU. Can you help us by adding your name to the citizens initiative?
In Europe, over the last 50 years an area the size of Hungary has been covered in concrete for human settlement and industry. This is only getting worse with ever more development, industry and intensive agriculture. The planet’s soil is being consumed at an alarming rate. Land used for urbanisation is only the tip of the iceberg, as soil in Europe faces many threats:

Over 250.000 sites are chemically contaminated,

almost half of the agricultural soils are threatened by the depletion of humus,

millions hectares are damaged by wind and rain erosion

in many Mediterranean countries desertification is advancing.

Europe has the duty to preserve its most important natural resource: soil.

A European Citizen’s Initiative is an official way for ordinary Europeans to call on the European Commission to act on the things citizens care about. To succeed, the Commission asks for one million signatures from at least seven member states. To safeguard Europe’s soil, we need every single one of us to sign.

The ECI is one way we can achieve that, using people power from all over Europe to take action. Can you help us protect our soil by signing up to this citizens initiative?
Protect the soil now. Sign the European Citizens’ Initiative

Happy Gardening,
