Plant clematis 5cm deeper than they were growing in their pots \u2013 this encourages new shoots from below ground level and helps prevent clematis wilt. Angle the plant slightly towards its intended support.<\/p>\n
Remove the plant carefully from its pot, teasing out any circling roots. If the root ball is very congested, make several vertical cuts with a sharp knife to encourage new root growth. Position the plant so the soil level will be 5cm above the original root ball surface.<\/p>\n
Backfill with your improved soil mix, firming gently as you go. Water thoroughly after planting and apply a thick mulch of organic matter around the base, keeping it clear of the stem itself. Install support structures immediately \u2013 clematis begin twining almost as soon as they start growing.<\/p>\n
How much water do clematis need?<\/h2>\n
Newly planted clematis need consistent moisture for their first year, requiring deep watering 2-3 times per week during dry spells. Established plants are more drought tolerant but still appreciate regular watering during flowering periods.<\/p>\n
Apply water at soil level rather than overhead to reduce disease risks. A good soaking once or twice weekly is better than frequent light watering, which encourages shallow root growth. Container-grown clematis may need daily watering during hot weather.<\/p>\n
Signs of water stress include wilting leaves, poor flowering, and premature leaf drop. However, waterlogged soil is equally damaging and can lead to root rot. The soil should be moist but never sodden.<\/p>\n
What fertiliser do clematis need?<\/h2>\n
Feed clematis in early spring with a balanced fertiliser, followed by monthly liquid feeds during the growing season. They’re hungry plants that respond well to regular feeding.<\/p>\n
Apply a general-purpose granular fertiliser (such as blood, fish and bone) around the base in March, working it lightly into the soil surface. From April to August, provide fortnightly liquid feeds with a tomato fertiliser, which provides the potash needed for good flowering.<\/p>\n
