Container planting

With the size of average sections shrinking and people building outdoor lifestyle areas near their houses container gardening has become a popular way of growing plants, giving many advantages. A wide range of looks can be achieved with the use of various different pots and these can be moved around to suit the setting and indeed completely change the landscape.

Many New Zealand plants are suitable for growing in containers, both for outdoor and indoor use. Larger tubs and containers can be used on patios, terraces and decks, or simply as a feature in the garden or at the entrance.

The main points when container planting are as follows:

• A suitable container. Choice of a container is important. Its external appearance must suit the situation that it is to be placed. It must be large enough that the plant does not quickly out grow it. The container should be shaped so that it is easily moved and repotted if necessary.
• A suitable growing medium. There are a number of growing mediums that can be used for container planting but the most important thing is that they have a supply of long-lasting nutrients and are reasonably resistant to drying out. A soil based mix or peat based potting medium can be used with the addition of slow release fertilizers that can be in granules or a tablet form, and water retentive products like gels, granules or sphagnum moss.
• Adequate drainage. It is important the chosen container has adequate drainage. That it has sufficient holes that allow the surplus water to drain away and that they do not become blocked, and that you use sufficient drainage material in the base.
• Suitable plants for the situation. Choosing a plant for the situation is important. Being aware that you choose a plant that will suit your needs, but also that the plant is suitable for the conditions of the site, e.g. not using a sun loving plant in a shady, cool site.
• Regular maintenance. Container plants need regular maintenance. Watering is the most important and even a few days neglect can result in leaf fall. Once the plant has become well established it is important to regularly feed the plant to maintain a healthy growing condition. Also repotting of the plant can be done every 2 years. It is also important to regularly remove dead and dying foliage that may encourage fungal disease, and to periodically check the plant for pests and diseases.
