We have both agreed on a final list of seeds that have made it through to this years polytunnel bootcamp where each plant will have the chance to perform and prove its worth. I wonder which of our selections will be the Leon or Leona of harvest 2008. This is the horticultural version of X-Factor , or should it be F1-Factor!
Armed with 'the list' I have mapped out the polytunnel using a very basic method ... one of my average sized steps is equal to 3cm on my diagram. And so, taking into account my notes of where everything grew this season, and looking at my video clip of the tunnel in mid summer to remind myself about areas I had already forgotten, I have planned where I will plant everything. At first glance it all looks totally random, but no, there is method there, honest!
First of all I look at the aspect ie where north, south, east and west lie. Tall plants I put along the northern end of the tunnel. This is so that they will not shade out other smaller plants during the long summer days as the dawn sun first enters the tunnel from the west, then full glaze from the south, and by evening it moves around to shine from the east. By then the shading won't matter so much, the smaller plants will already have had a good day long dose.
I also take into account what plants were growing where this season and do my best to rotate so that the three plant types aren't grown in the same plot two seasons in a row, and aim to give three years before that 'group' returns to a bed (roots, brassicas and others). This gives the soil a 'rest' from the particular nutritional demands of each plant group, preventing depletion of certain nutrients and trace elements. Any good gardening book gives examples of plot rotation but this is the one on my shelf.
I also refer to my notes to see if I need to plant more or less of any crop for next season and use that information to measure out the revised plot sizes. Consider whether you and your neighbours were sick of the sight of courgettes (probably!) or craving for more sugar snap peas?! For example last year I grew 'one step' of pea plants, this year I want to grow a little more to meat our families demands, so the bed will increase to one and a half steps wide.
If theres still room for maneuver I put plants I harvest on a daily basis, such as salad leaves and herbs, closer to the entrance. There are also parts of the tunnel that are watered overhead, others watered by seep hose, and patches within that arrangement that I've noticed that are particularly dry or wet. Again I use these features to decide where to put which plants. For example the tomatoes, peppers, chilli, aubergine and courgettes all go in seep hose zones because damp leaves for these plants leads to problems with mildew or leaf burn, whereas salad leaves, carrots and most herbs seem to enjoy the sprinkler.
Everything that is permanent has been drawn in ink ie the structure and raised beds. I have a copy of it now so next year I can just print off a blank and start again. I draw in the various crops with pencil so I can move it all around and cater for mid season changes ... I'm expecting that for some reason or another I won't be able to stick entirely to the plan ... say for example two weeks of kids with chicken pox, or a pig gets in and roots up a bed, or I just forget we have a polytunnel for a while because I get sidetracked and a tray or two of seedlings shrivel up and die, or the dog chooses to lie on the salad leaves. You may have guessed that most of these scenarios are more than mere meanderings of my imagination.
The artichokes are perennials (ie they grow year after year), as will be the planned vine. There will be flowers planted among the beds, including borage, pot and french marigold, and sweet pea. The latter is actually still flowering well in the tunnel now which is a wonderful surprise. Some new crops we intend to add this year include strawberry and melon, and Dan is very keen to have a go at asparagus ... yes he is very patient ... it takes 3 years to get a crop! I daren't grow it myself because I could just imagine how furious I'd be at some toddler who may come along on the 4th year and yank the whole lot out for fun!
