Overview
Growing roses beside the right neighbour
Rose (Rosa spp.) is a flower in the Rose family. Woody flowering shrub, often underplanted with alliums and herbs.
Alliums around roses are an old gardener's trick against aphids — and the herbs bring in the insects that eat them.
Give plants 24–36 in in full sun. Aim for rich, well-draining loam, ph 6.0–6.5. In most gardens the crop sits in USDA zones 3-10 and is ready in about 60-90 days (first bloom from bare root).
