wait until this cold snap is over before planting them otherwise you'll get cold hands (and therefore too cold for little plants to get established) be advised that any covering of the soil between plants is a great home for slugs!! no need to put down straw yet, wait until flowering / fruit forming. straw, once it's been wetted, sticks together (starch / glue), so after teasing it out (technical term), water it with a rose on a watering can! ;)
