Greenhouse, Sheds and House plants

• Sow tender annuals in a heated propagator.

• Start Dahlia tubers into growth.

• Watch out for fungal diseases and spray if necessary.

• Deadhead amaryllis leaving the flower stalks to die down. If you keep feeding and watering them you may get further flowers in late summer as well as next winter.

• Passion flower and jasmine can be thinned out to keep them tidy. Cut last years growth back to two or three buds from the main frame.

• Prune back stems on pot-grown over-wintered fuchsias. Soft tip cuttings (these are the soft and bending stems) can also be taken from fuchsias this month.

• Top dress containers with fresh compost.


Trees, shrubs, hedges and climbers

• It’s still okay to plant deciduous hedging plants, shrubs and trees.

• Some shrubs such as Buddleja are usually cut back very hard (stooled) to keep them at a manageable size.

• March is a good month to plant roses especially if you live in colder areas but remember not to plant them where roses have been planted previously.

• Prune standard and bush roses as they start growing but before the leaves start to unfurl.

• Don’t prune any spring-flowering shrubs until after they have flowered otherwise you will lose this years display.

• Renovated deciduous climbers will be easy now – live stems will have buds so prune out the dead stems with no buds.

• If you have any plants with leaves that are two colours (Variegated - often green and white) cut out any branches with leaves that are all one colour or the whole plant will eventually revert to only one colour and lose its interest.


Soils, mulching and weed control

• Weeds come back in to growth - deal with them before they get out of hand.

• Place mulch around new plants to prevent weeds, retain moisture and improve the soil.

TOP TIP: If you didn’t do it last autumn it’s not too late to scarify the lawn – raking out dead moss and thatch. This will encourage new grass growth.

TOP TIP: If the soil is wet stand on a plank of wood rather than treading on the soil otherwise you may compact the soil.

TOP TIP: Try to protect any new growth on lilies, delphiniums, hostas and similar plants from slugs and snails.

TOP TIP: Remember to water azaleas with rainwater and not with tap water.

TOP TIP: If the leaves on your indoor Cyclamen start to turn yellow you may be over-watering it.

TOP TIP: Keep an eye on the water level of your pond to make sure the frost hasn’t caused any leeks.
