Strawberry Fields Forever …

mara des bois strawberries
Wild alpine strawberries have a concentrated burst of aromatic flavour yet are frustratingly tiny.  Wouldn’t it be great if you could get that same intense taste in a full-sized strawberry?  Apparently you can, with a French perpetual variety called Mara des Bois.

Strawberry beds need moving and replanting every three years as plants become diseased and yields reduce.  Fresh plants from a disease-free source should be planted in a new bed.  As I didn’t get my plants until this spring I have been very disciplined, removing the flowers so the plants use all their energy to establish their root systems before they go for gold and give us their delicious berries next year.  (If you plant in the autumn then you don’t need to do this as the plant has already established itself over the winter and spring before fruiting begins.)

borage towering over strawberry plants
I am interested in companion planting but I like to really understand why something works.  Many sources quote, time and again, that borage is a great companion for strawberries.  But, when I tried to dig a little deeper and find out why this should be so, the evidence is thin on the ground.  I’m suspicious that people are repeating each other endlessly, rather than writing from a position of real knowledge, a bit like the bunkum about throwing away mussels that refuse to open after cooking.  Beware the unsubstantiated ‘truth’!

Despite my growing doubts, I went ahead and planted some borage on the edge of the new strawberry bed.  It’s a great plant, the bees love it and the flowers are both beautiful and edible.  The problem with borage as a companion for strawberries is that it is a big sprawling plant and very quickly totally overwhelmed my new strawberry plants so I took out the all but one.  (The bees still benefit from other borage plants elsewhere in the garden.)
If you know why borage is a good companion plant for strawberries and how they should be planted to benefit rather than overwhelm, please post a comment.

strawberry between a rock and a hard place
And to something that does work: for the last few years I have used a neat little trick that I learnt from Sepp Holzer (The Rebel Farmer  and Sepp Holzer’s Permaculture). He observed that the strawberries that did best for him were sited near to rocks and he worked out that the rocks acted like storage heaters for the tender plants.  I found some flat black stones and tucked them around the plants and it seems to benefit the production and ripening of fruits.

We must be patient to see how my strawberry bed performs next summer.  Mara des Bois are resistant to flowery mildew and are perpetual (fruiting from May until first frosts) yielding up to 1kg per plant. I have high hopes for the flavour and the yield from my fifteen plants. Plenty enough fruit for topping our morning muesli, making jam, ice cream and pies and Stuart’s favourite: macerating fresh strawbs in Cointreau and sugar. Delicious!

Cob, oak window frames and squeezing in stairs …

cob ball test
I spent all day yesterday working outside my comfort zone.  And that after a fitful night’s sleep when I was either staring at the ceiling with elements of the barn renovation circling mobile-like around my head or dreaming about them.  Exhausting!

Having taken down several oak beams and with new, engineered I-beams on order, I have to chisel out pockets in the wall for them to sit in.  The dry earth that’s been removed gets remixed—with the addition of water and some straw—to seal them in.  I’ll also need this “cob” to fix a new oak window frame.  I’ve only ever worked with this material at friends’ houses (most recently on Bruno’s and Mélanie´s straw bale house build) and have never been in charge.

The weight of responsibility is heavy: the mix must be right.  Too much clay and I’ll have cracks, too much sand and it won’t hold together.  My reference guide is Building With Cob: A Step-by-Step Guide by Adam Weismann and Katy Bryce.  Perhaps I’m worrying too much, as I’m reusing the earth from a wall that’s already stood for over a hundred years but I ran a couple of tests anyway.  The standard one is to half-fill a jar with the soil and top it up with water, shake vigorously to thoroughly mix the contents and leave to settle out.  The other one involved making a fist-sized ball and then dropping it from waist-height.  If the ball breaks up, there’s not enough clay and if it pancakes, too much.  Mine held its shape (see photo at top).  I then left it while I attended to other things, with the intention of taking a photo later.  This abandoned ball of mud in the middle of a path caused nine-year-old neighbour Camille to laugh as she came to see what we were up to: another example of the eccentricities of her English neighbours.

"double carré en bois"
The next task was to assemble an oak frame that will straddle the cob wall and receive the window.  Using some drawings from a local association dedicated to the preservation of old buildings with original building techniques, I’d fabricated the individual pieces some time ago.  I got the same drawings out, cleaned out the mortises and shaved the tenons until I could dry fit everything.  Dry fitting is an important step as I renumbered the pieces three times until I had them in the right position: not great for my self-confidence and making gluing up stressful, with much checking and re-checking of the frame against the drawings.

And, as if that wasn't enough for one day, I had to design the stairs.  One works out the “total rise” from finished floor height of the entrance hall to the same upstairs and divides it by 220mm (maximum individual rise for each step).  One then rounds up to the nearest whole number (each step must be the same to avoid tripping and falling) and recalculates to obtain the actual rise, which will be less than 220mm. 

where the stairs will go
The treads, or “goings” are next.  I need to avoid a beam that I can’t remove (maintaining 2 metres head-height) and then I can’t go too far over the width of the building, as that won’t leave enough room for passage to the bathroom.  I had visions of future holidaymakers staggering, bleary-eyed, for a nocturnal wee and walking (falling!) straight down the stairs.  After much measuring, drawing, pondering and surfing, I found the solution: a “Z” or “S” shaped winder.

Have in mind a ceilidh or barn dance caller, this is how it goes: one step, three winders to the right, two steps, three winders to the left, two steps, do-si-do and take your partner by the hand.  I then phoned Simon at, gave him the dimensions and my credit card number and relaxed.  Being of a nervous disposition though, having scoffed lunch, I dragged Gabrielle out to the barn to confirm I had everything correct.  I hadn’t!  I might have remembered the thickness of the floor but I’d forgotten 200mm of floor joists … oops!  A hurried phone call to Simon and we recalculated and added another step and all was well.  A cold feeling ran down my spine as I imagined getting the stairs back to France, offering them up and finding them short.

[An aside: why am I buying stairs in the UK when we live in France?  Buying local is ethical, I know, but the price difference on some things is astonishing and it fits it (by the skin of its teeth and the help of Simon) with a planned trip to see my mum.] 

So, you see, the eco-renovation of our cob barn is well under way to provide further holiday accommodation but not without some tears and tantrums!
