Pot up plants and grow them on in frost free conditions until all risk of frost has passed. When plants are well grown, gradually acclimatise them to outdoor conditions over 7 to 10 days before transplanting into borders and containers. The herbaceous perennials in this collection can be grown in any moist, fertile soil, in sun or semi shade. Work some compost or general fertiliser into the top 20cm of the soil prior to planting.
In autumn, cut back the old foliage to ground level and apply a mulch of well rotted manure or garden compost to the base of the plants. Lift and divide overcrowded clumps of perennials in autumn to maintain their vigour.

  1. Not as promised

    By S Hamson 13-11-2015

    Ordered these expecting plants of around 30cms in height as the picture shows (exampe plant), intended planting them in gaps and expected to see them due to 'Powerliner' marketing. All were much smaller plants, root development was lacking in a lot of them, some plants were hardly more than plugs in growth. I received a lot of double ups, which meant I did not receive 24 different plants, and having ordered well in advance would expect to get what I ordered. First let down with T&M which was not resolved as expected.
