Rachel your soil is prob hungry and impoverished and dry. you may water every day...not sensible to do that really. A sloping border is free draining...not great for scabious.
check out your hardy geraniums......different varieties require different comditions. Some will thrive on a slope or dry soil; others need moisture. Always assess your plants' individual needs before planting
for me,,the best solution to mildew is enriching the soil....get some good moisture holding material into your soil
lift your scabious in autumn and put compost into the planting hole. a thick mulch in spring,,following a good watering, helps too.
mildew is a result of plants stressed by drying out. another solution is to grow plants that enjoy dry conditions.....and there are plenty of those
