Geums are easy to grow, flower for a long time and look great planted amongst other perennials in a border. Their basal clusters of leaves are semi-evergreen, forming useful ground cover in winter.
Most geums need light shade and a moisture retentive soil. The nodding flowers of Geum rivale benefit from particularly shady spots with continually moist soil; G. chiloense loves sunshine, so long as the soil stays moist, while alpine types such as G. montanum thrive in more free-draining, open sites.
Geums rarely suffer from pests and disease. Tips for success include dividing clumps every three to four years and deadheading your favourite cultivars to prevent less desirable seedlings springing up amongst them.

Jobs for the weekend: Neaten up hedges
Although it’s best to leave major hedge-trimming for another few weeks to allow birds time to leave the nest, you’d be amazed at the difference a little judicious pruning of vertical surfaces makes, especially on entrances and exits. Just trim them so they’re crisp and it will tighten up the whole garden.
Jobs for the weekend: Plant out courgettes
The nights are now warm enough to plant out courgettes with confidence. They will grow well in the soil or in containers if you enrich your growing medium with some garden compost or well-rotted manure. Plant only one plant per large container, put it in a sunny position and water well for harvests right through into late summer.
Jobs for the weekend: Take softwood cuttings
Now is a good time to take cuttings from deciduous shrubs, like Fuchsia or Philadelphus. Choose a new shoot that has no flower buds on it and remove it by cutting beneath a leaf node. Strip off the lower leaves and push the cuttings into free-draining compost. Water them and place them in a sheltered position and they’ll be ready to pot on in autumn or next spring, once roots have formed.
