Have you been watering a lot lately midnightvelvet? Had it been hardened off....was it outside in the garden centre or protected? Your hebe would not have enjoyed too much watering either, esp right now
On the other hand,since they have only been in for 3 weeks lift your plants and check the rootballs.....are they dry? Or rootbound?
if everything looks ok then I would say the plants are suffering right now from cold winds etc. so should improve in a few weeks
I think people have an obsession to feed their plants all the time...phostrogen is not great anyway at this time of year. Still cold for plants to want to grow much. Always better to feed the soil.....at planting time mix in compost etc., and then mulch.
your ex potted plants! Good to loosen the roots and good to water them well now but don't keep watering or feeding them. Same as before, put compost and slow release fish blood and bone in the soil.
