Container Gardening Essentials

Containers let you garden on patios, steps, balconies and even windowsills. They are also a great way to control soil quality and move plants to the best spot.

Choose the right pot

Size matters. Bigger pots hold more moisture and buffer temperature swings. Use containers with drainage holes; decorative pots without holes should hold a nursery pot inside. Consider weight, especially on balconies.

Use quality potting mix

Garden soil compacts in pots and drains poorly. Use a lightweight potting mix with compost and a slow-release or organic fertiliser. For long-term plants, add grit or perlite for drainage.

Water consistently

Containers dry out fast. Check moisture daily in summer. Water until it runs from the drainage holes, then empty saucers. Mulch the surface to reduce evaporation. Self-watering pots are useful for busy gardeners.

Feed regularly

Nutrients leach out with watering. Feed with a liquid fertiliser every one to two weeks during growth, or use slow-release granules. Flowering and fruiting plants need more than leafy herbs.

Plant for impact

Use a thriller, filler and spiller combination for ornamental pots: a bold upright plant, rounded fillers, and trailers that soften the edge. For edibles, group plants with similar water and light needs.

Overwintering

Protect pots from freezing; roots are more exposed than in the ground. Move tender plants indoors, wrap pots, or choose hardy species. Refresh compost and clean pots between crops.
