My strawberry plants are propagating themselves. They put out runners - long horizontal stems with little baby plants on the end. The baby plants put down roots when they find a bit of soil, and the stem can then be cut to create an independent plant.
I need to weed the strawberry bed as you can see. Then I will be able to see where the plants are and decide if I need to move any of the runners. I'm happy to get more strawberry plants for free.
If you're wondering what all the white stuff is, it's shredded paper I used instead of straw to keep the fruits off the ground and away from slugs. It works well, but provides no defence against birds.
