strawberry runners and weed suppresant fabric

the first year i had my allotment my neighbour kindly gave me a load of strawberry plants

that was 2 summers ago, so the plants are in their 3rd year now.  will they go on producing well or will it tail off from now on? 

i notice that  some  are sending out runners, and, as i am growing  through weed suppresant black mesh this year i dont really know how to turn them into baby strawberry plants, (some from previous years just rooted themselves in the strawberry patch, no bother).

I would like to encourage them to root in a pot, but they are like little nodules on a straight stem at the moment

Fix down the bit where the little nodules are,  into a small pot of compost, using a bit of bent wire (cut up coat hanger?)   

Really? thats ingenious, i'll do it tonight, though i may well use unravelled paperclips as i cant remember when i last saw a wire coathanger

wow gavin, that looks like a strawberry production line, lol.

but great pictures, when do you cut the umbilical cord then

I potted mine up like Gavin. When the runner has rooted sever from mother plant .
I started off with 10 plants three years ago,,there are now about 700 + ,and these are sending out
runners also.
After about four years strawberry plants start to deteriorate,potting on runners help preserve your stock.

Does splitting the crown have the effect of rejuvenating strawberries? I inherited some which have to be 3 years+ and this year dug up, cleaned and split them. They are fruiting well, but I don't have much of a comparison.

Thanks!
