For success always grow geums in a moisture-retentive soil. They're happy in any pH but won’t cope well in very dry soils or in a baking hot south-facing border.
Geum rivale types prefer a shady spot and are ideal partners for hellebores. Geum chiloense types can cope with more sunshine but their semi-evergreen foliage is easily scorched in hot weather.
Geums won’t cope well with a sodden wet soil in winter.
Improve the water retentiveness of the soil by digging in plenty of organic matter before planting. Firm plants in well and water. Provide with extra water in very dry summers.
Geums spread by rhizomes. Side shoots are easy to dig up and can be replanted in the garden. Plants can also be divided in spring and will set seed.
Geums are trouble-free plants. Deer and slugs aren’t even interested in them! But if grown in containers they can be susceptible to vine weevil. Vine weevil damage is simple to detect. Adult weevils eat notches out of the foliage from spring to late summer. Vine weevil grubs will eat the roots, often causing the plant to die. Burn affected plants or treat with nematodes or Bayer Provado Vine Weevil Killer.
