  • Q:

    When should I plant Delphiniums, Foxgloves and Hollyhocks, and what will I gett in a pot?

    Hi there, I have a brand new, small, garden (approx. 36' by 30') and am in the process of creating borders. I'm aiming for fairly deep borders as I would like loads of cottage garden flowers. I am thinking of having a few evergreen / deciduous shrubs here and there to form some permanent interest. My gardening knowledge is more or less at the 'beginner' stage so I need some advice please. Is it okay to plant the shrubs now as long as the ground isn't frozen? When should I plant the perennials and annuals? Spring time? When I order for example Hollyhocks, Delphiniums and Foxgloves, and what do I get in the pot? Is it one plant that will produce one flowerhead? If I wanted to make a big colour impact, would I need to order loads of each plant? I look forward to hearing from you. Many thanks, Lynn

      Hello Lynn, You can plant any fully hardy plant at any time of the year
      as long as the ground is not frozen, but the ideal times are spring or
      autumn. Annuals only live for 1 year, some will flower in winter, while
      others flower in summer, so the planting time will depend on what type
      they are. As for the herbaceous perennials, these can be planted anytime
      as long as they are hardy, you will get 1 plant per pot. Each plant and
      species will produce flowers in different way. The ones you mention
      will generally produce 1 main flowerspike and a couple of smaller
      side-shoots, and if you cut them back when they start to fade you can
      often encourage a second flush later in the year. Finally then, if you
      want big impact, then yes you will need a lot of plants. I hope this
      helps. Helen Plant Doctor

  • Q:

    When should I plant Delphiniums?

    I am interested in purchasing some Delphinium plants. When is the best time to buy and to plant? I live in Scotland and the winters here are both damp and cold.

      As a rule hardy plants that are grown in containers, can be planted at any time of year as long as the soil isn't frozen solid. The best times are in the autumn when the soil is still warm enough to encourage root growth but the plant isn't in active growth, or the spring before the temperatures start to rise, however you can also plant throughout summer as long as you make sure the plant is kept well watered.

The Chelsea Chop (and other methods of extending the flowering season)

Many gardeners who are happy, even gung-ho, with the secateurs when pruning shrubs and climbers are surprisingly reluctant to take the shears to herbaceous perennials. Maybe this is because it just doesn't seem quite right to be cutting back all that new
