Gardening Gerald Filipski One-Container Gardening Container gardening continues to inspire gardening thinking that is outside the box. In the past, pots and containers were used for flowering plants almost exclusively. Today, it is not unusual to see perennials, small evergreens, and even vegetables growing nicely in a container on a balcony or deck. A single container can be a mini-garden all on its own. Using a single container does not restrict your choices in what and how you plant. An excellent gardening system for small spaces or for a single pot or container is a three-tiered system. With this system, tall or climbing plants are planted at the back of the container up against a wall or trellis. Medium height, bushy plants fill in the majority of the container while cascading plants fill the front of the container, softening the composition of the container. This one pot works with all three dimensions of gardening, namely, vertical height, vertical drop and the horizontal. Adding a trellis to a wall can be as simple as stringing some nylon 18 | arta.net garden netting on the wall or as ornate as adding one of the popular obelisk-style trellises if you have the space. There are several fast-growing annual vines, such as morning glory or canary vine, that will rapidly fill in the background of the planting without overcrowding the other plants in the pot. If flowers are not your choice, you may consider a small salad garden in one container. You can have cucumbers climbing up the trellis, cherry tomato plants in the centre, and a variety of lettuces growing on the border of the container. The beauty of this example is that the arrangement would be very aesthetically appealing in addition to being very functional. Vegetables can be quite attractive plants in their own right. The textures and leaf colours are pleasing to the eye. One of my favourite looks is a container full of colourful kale. The number of plants you fit into a container can vary. If you are prepared to do the extra work, you can cram the container chock full of plants. The extra work comes in the form of consistent watering and fertilizing. With a container full of plants, the requirements for water increase dramatically. If the location is a south facing one, you may need to water twice a day during hot months. Fertilizing should be done with each watering. A good balanced fertilizer like 20-20-20 should be applied at the recommended strength with each watering. The recommendations for spacing plants can often be adjusted to your needs. The square foot gardening system developed by Mel Bartholomew is one example of high-density
