Hanging baskets are known to dry out quickly and become high maintenance to keep them looking good. If this is your problem, remove the plants carefully so as to prevent root disturbance. Keep the basket liner in place and place a babies disposable nappy on the liner with the plastic side facing the liner. Replant and water well. The nappy will absorb water which is then available to the plants after the soil has dried out. This will save a lot of time and your hanging baskets will benefit. The same can be done with plants in pots and retaining walls.
