Weekend work: Time to re-pot cyclamen corms


What to do

* Cyclamen corms that have been resting can be started into growth again now in a greenhouse. Clean off all the old leaves, shake any loose soil off the corm and repot each corm in the smallest pot that it will fit into. Use John Innes No 1 compost or its equivalent and set the corm so that the top just shows above the compost. Spray the corm every day with tepid water to start it into growth. Do not bring the plant into the house until there are at least four to six flowers in bud.

* Remember your camellias, especially if they are growing in pots. Flower buds are being initiated now for next spring's display. If the plant is too dry, it will not have the strength to produce these buds.

* Over the next month, take cuttings of tender fuchsias and geraniums. Choose strong, healthy shoots for geraniums and crop off the top 10cm/4in. Trim the cutting to a point immediately below a leaf joint, remove all mature leaves and any flower buds and pot them up in a mixture of compost and sand. Do not cover them.

* Stem cuttings can be taken of hibiscus, hydrangea, kolkwitzia and perovskia (Russian sage).

What to see

*  If you haven't recently been along the concourse by the South Bank Centre in London, go soon. The space has been transformed by architectural practice What If: Projects (what-if.info) into an instant garden, contained in 35 galvanised wheelie bins. It'll be in place until 8 Sept when the trees go to permanent homes in four community orchards.
