August Monthly Inspiration
News and Gardening Tips
Romney poppies or Romneya coulteri make splendid border plants. They may start flowering in July but are often at their very vest with secondary flowers in August. The problem with this plant is that propagation from cuttings is more or less impossible. Propagation has to take place from root cuttings dug and chopped with a spade in winter when the plant is dormant. These can then be nurtured into growth and re-rooting in the mist bench or in large deep trays which are a mixture of peat and sand.
Agapanthus come into their own in August. There are so many summer flowering plants that they look good with when grown together. Hydrangeas, Verbena bonariensis, Kniphofia and yuccas spring to mind. The range of new and different varieties of agapanthus continues to grow. A. inapertus ‘Graskop’ has the darkest violet blue flowers and A. ‘Queen Mum’ is bicoloured; white flowers with blue at the base. Variegated leaved agapanthus such as ‘Golden Drop’ provide a superb contrast between leaf and flower colour too.
Time to prune your climbing roses which will have finished flowering. Prune out any excessive new growth shoots and weaker shoots and tie in the best new shoots to wire or trellis supports to prepare for an even better show next year.
If you have forgotten earlier catch up too with the secondary pruning of your wisteria to remove the long tendrils of new growth which are drowning the energy of your plant and which will reduce its ability to flower next year.
August is the best time to make softwood cuttings. Hydrangeas, fuchsias and other semi-annual plants which may not survive the winter such as Osteospermum and Argyranthemum.
