As the weather heats up borders and containers should be looking their best with plenty of variety and colour.  To keep perennials and annuals looking their best and flowering for as long as possible it is important to deadhead faded blooms.  During long dry spells only water borders if they really need it and it is better to give plants a good soaking once a week than to water a little each day.  Applying a thick mulch around plants will help to reduce moisture loss.
