A Star is Born!
The latest 'must have accessory in a polytunnel potager is'..... a Robin!! Little did I think last year when I was clearing the rapidly developing jungle of brambles and weeds beside my polytunnel that the baby Robin who found all this activity of great interest would become a bit of a Twitter sensation! The jungle had sprung up in a rather neglected bit where I'd put a lot of pot plants and cuttings for shelter over a while before they found a home - as you do - and I hadn't got round to tidying it. Then I broke my ankle last March, couldn't do a thing for three months, and with the mostly mild wet winters of the last few of years, the brambles and general mess was growing at an exponential rate! I was utterly charmed by a dear baby Robin, who appeared as soon as I started on it, and got under my feet the entire time I was clearing it. He must have been hatched in a nest somewhere in the 'jungle' there, and he spent several days grabbing every woodlouse and beetle he could spot! But the best thing was that HE had clearly spotted a very useful pet human, an alternative 'Mum' - who would not only provide him with regular easy meals, a sheltered spot to groom himself or to hunt for insects in wet and windy weather - but also somewhere safe to hide quickly from the Sparrowhawks and Buzzards which are constantly hunting over here due to all the biodiversity - the birds and small mammals - which our organic land attracts.

Robin's antics since have proved without doubt (if there ever was any!) that polytunnels aren't just good for our physical and mental health, as I'm always saying, but they also provide constant entertainment as well - in the form of all the wonderful biodiversity (Robin included) which they can attract if we plant them as I do - with flowers and herbs as well as food for us! Every day that Robin's antics make me smile or laugh - and he's clearly done that for many other people too. I'm really thrilled that he has, because right now we all really need something to cheer us up - especially me, having lost a couple of dear friends recently. There also seems to be so much depressing news almost every day about climate change, plastic pollution of our oceans, pesticides in food, or the dreaded Corona Virus - which is such a worryingly unknown quantity. Perhaps he's also helped to make many people appreciate, all the more, the wonderful biodiversity which we share this planet with - making them even more determined, as I am, to do everything we can to save it. That Robin may be only a tiny fragment of feather, bone and intelligence - but is a big Hero - especially to me!
The Totally Terrific Tomato Festival will be happening again this year we hope - so get set sowing those tomatoes!
Dr. Matthew Jebb & I, with the 2017 display of tomatoes displayed in the beautiful glasshouse at The National Botanic Gardens in Glasnevin. The 2018 and 2019 record-breaking displays were bigger and even better - taking up the whole Teak House as you can see at the beginning of this blog post.
So why IS genetic diversity in tomatoes important? - Whether we grow them or not, most of us eat them!
March is always such an exciting month in the polytunnel - it's my horticultural Narnia and a very 'alternative' world to the one prevailing outside! In there it's a very different story, spring is already everywhere. Primulas, narcissi, violas, feverfew and wallflowers flowering at both ends, and in the little gardens planted around the foot of the grapevines halfway along the sides.There were even a couple of bumblebees in there over the last couple of weeks - anytime there was a rare mild day and the sun warmed the tunnel! I'm so glad that as always, I'd planted some early flowers in there to attract them in - the scent of primulas and wallflowers is wonderful when I open the door. The peach buds are already swelling and In three or four weeks they will be in full flower. Encouraging bees to visit the tunnel to do some of the pollination by growing flowers for them will mean plenty of juicily delicious peaches again come July - although that seems a long way away right now!
This is how I sow my Tomatoes - and other tender crops
Use Peat-free seed Composts
Potting on tomato seedlings
Protecting seedlings while providing good air circulation is key
Shading small seedlings is important from now on
Keep a careful eye out for slugs or other pests in propagating areas

- The overwintered calabrese 'Green Magic' (from Unwins) has yet again come up trumps (sorry!) and it's done really well despite a much colder winter than last year. On the very worst nights it was covered with a several layers of fleece. It's such a sweet variety and not just good for lightly steaming but also really good raw for dipping individual florets into hummus or any avocado dip. It's a terrific variety, thoroughly reliable and long- cropping all year round both in the tunnel and outside. It's the only one I b other to grow now in the tunnel. I sowed two dozen last month in the propagator - one dozen will be planted when big enough into the tunnel, and will crop by May. The other dozen will be hardened off and planted outside, which will make them crop about 3 weeks to a month later in a normal year. This is a good way to spread the cropping time of any crop.
I like to be able to pick an interesting and varied salad every day all year round so I'm really grateful for luxury of a polytunnel. There are still plenty of lettuce, endives and other leaves of various sorts - mostly loose leaf varieties that have cropped really well all winter. 'Lattughino' is one of my favourites - with crispy bronze-tinged leaves. Jack Ice is another - rather like an Iceberg but a loose-leaf type that you can pick all winter and then allow to form quite a nice heart from March onwards. 'Veneziana' an unusual sword shape Cos type and delicious, 'Belize' is another good one - an oak leaf that will also form fat hearts now. Fristina is another excellent crispy loose-leaf type. Good old 'Lollo Rossa' is great for some reliable red colour - and also the Cos varieties 'Marshall' and 'Nymans' - one's really spoilt for choice these days with so many new lettuce varieties every year - but you don't have to go for expensive F1 hybrids - some of the 'value' mixes - like B&Q's are fantastically cheap - 60 cents for 1200 seeds! Great if you're watching the pennies - costing almost nothing per lettuce! The value mixes mostly contain older varieties that are easy, colourful and reliable for all year round growing - either sown thickly for baby leaves or as individual whole lettuces. The endive pictured here - an old Italian variety 'Riccia Pancallieri' is very bitter when green - which I don't like - but if you blanch it by covering it for 2-3 weeks under a large pot as the old Victorian gardeners did - it is beautiful and really delicious in a late winter salad - with a nice fruity/sweet dressing like my walnut oil/cider vinegar/honey & orange dressing which goes with everything and is full of healthy omega 3 oils. The photo above of the blanched and un-blanched endive side by side really shows what a difference blanching makes!
