It looks nice, I much prefer it to the fence panels, it attracts moths and hoverflies and is evergreen. But the border always disappoints. It's south-facing on thin chalky soil. I've added loads of compost, mulches and chicken manure pellets out over 10 years so it's better, but plants just seem to fail to thrive there. Is it the ivy roots? Do I have to choose between evergreen fence panels and an abundant summer border?
