Spacing of Strawberry's

I've 'grown' about 70 runners and I'm going to have to ignore the rules to get them in their new bed!

"They do say"...to resist allowing the plants to fruit for the first year and so build up thier strength for the following year.

Cheers,  Tony.

The growbag spacing sounds pretty tight to me (more like commercial 'table top' growing, which probably involves quite intensive watering and feeding, and probably chucking the plants away after the season ends.)

You appear to be planning an elevated 10' bed but have only one 28" growbag, so I don't quite understand your plans - either way I'd put the 21 plants in a zigzag formation in the 10' X 1' bed which would allow at least some of the fruits to hang conveniently over the sides whilst also maximising the spacing.

My maths isn't up to working out what the actual separation would be but it would certainly be less crowded than the suggested growbag spacing.
