House plants

  • Water your house plants more regularly as the temperatures warm, check the soil before watering. Take a look at our guide to watering house plants

  • Try and keep house plants away from temperature fluctuations caused by draughts or central heating
  • Check your house plants for pests like aphidsscale insectthrips and mealybugs
