How Do You Plant and Look After Hanging Baskets So They Stay Healthy All Season?

A well-planted hanging basket is one of the most striking elements of a container garden — and one of the most demanding. Hanging baskets are exposed on all sides, dry out faster than ground-level containers, and must be densely planted to look their best. In return, they use vertical space efficiently and bring plants up to eye level where their detail can be appreciated. With the right planting mix, a reservoir liner, and a consistent watering and feeding routine, a basket can look spectacular from late spring through to the first frosts.

Choosing a Basket and Liner

Wire hanging baskets lined with coir or moss allow planting through the sides for a full 360-degree display — plants burst from the sides and cascade to create a ball of flowers. Solid plastic baskets with built-in drainage holes are easier to water but limit side planting and dry out slower. Whichever you choose, use a liner that holds moisture without becoming waterlogged: coir liners are biodegradable and effective; moss liners are attractive but dry out fast in wind; proprietary foam liners retain moisture best and are reusable. Cut a disc of polythene and place it in the base of the liner to create a small water reservoir before filling with growing mix.

Planting a Wire Basket

Rest the wire basket in a large pot or bucket to stabilise it. Line the base and lower sides with the liner material. Fill to one-third with growing mix mixed with water-retaining gel granules. Push trailing plants through the lower side openings from inside the basket, working from the bottom up. Add more growing mix, then plant the middle tier, then fill to the top and plant the upper section and central plant. The finished basket should be densely planted — gaps fill quickly once the plants start growing. Water thoroughly before hanging.

Best Plants for Hanging Baskets

Trailing and cascading plants are the heart of a hanging basket: petunias, surfunias, fuchsias, lobelia, bacopa, nasturtiums, and trailing tomatoes like Tumbling Tom all work beautifully. A central upright plant provides structure — geraniums, osteospermum, or a dwarf fuchsia. For edible baskets, cherry tomatoes (Hundreds and Thousands, Tumbling Tom Red), strawberries, and trailing nasturtiums (both flowers and leaves are edible) are effective and productive. Herbs in baskets — thyme, parsley, trailing rosemary — look attractive near a kitchen door.

Watering: The Critical Challenge

Watering is the hardest aspect of hanging basket care. Baskets in full sun and wind may need water daily, and sometimes twice daily in peak summer. Push your finger into the top of the growing mix each morning — if dry, water immediately. Water slowly until it drips from the base of the basket. A long-handled watering lance attached to a hosepipe makes watering at height much easier. In very hot spells, immersing the basket in a bucket of water for 30 minutes fully rehydrates growing mix that has become hydrophobic on the surface.

Feeding Through the Season

With dense planting and frequent watering leaching nutrients, baskets exhaust their growing mix quickly. Begin a weekly liquid high-potassium feed six to eight weeks after planting and maintain it throughout the flowering season. Slow-release granular fertiliser mixed into the growing mix at planting time extends the window before feeding needs to begin. Deadhead spent flowers regularly — or choose self-cleaning varieties that drop their spent blooms without intervention. Trim trailing plants back by one-third in midsummer if they become leggy, which rejuvenates growth and extends the display.
