CONTAINER GARDENING
One of my favorite forms of gardening is container gardening. My container gardens are only limited by imagination and the plants available. Anything that can grow in a garden can also be grown in a container. Just provide those plants with a few basic needs: a suitable container, a growing medium, water, nutrients and light and they will grow.
Of America’s 60 million gardeners, probably 90% of them grow plants in containers. Some gardeners don’t have a yard. Also, container gardening is a smart alternative if you are restricted by too much shade, poor soil, too little time, limited mobility or a difficult climate. Best of all, growing in containers brings your garden right up close, creating a sense of intimacy that you just don’t get in an ordinary backyard garden.
Here are some simple tips to help you with your container gardening:
Containers for your plants must be big enough to support your plants when they are fully grown, hold soil, and have adequate drainage. Without proper drainage, the plants can suffer from inadequate root aeration and excessive moisture. They will literally rot. Have drainage holes on the sides of pots rather than the bottom so excess water can drain away and roots won’t get waterlogged. Line the bottom of your pot with newspaper (a coffee filter works in smaller pots) to prevent soil loss. Also, line the hanging baskets with sphagnum moss for water retention.
Anything and everything that fulfills these basic requirements can be used. Use your imagination! For example, among the containers that can be used are clay pots, plastic pots, terra cotta pots, bushel baskets, hanging baskets, wooden crates (lined with plastic so that they will hold soil), barrels, heavy gauge wire baskets, glazed ceramic, hay racks (again lined with plastic), wooden planters, concrete containers, and even old boots or shoes. As you can see, you do not need to spend a lot of money on containers. Keep your eyes open for suitable containers at garage sales. Watch discarded household items put out for collection. If you want something fancier, try building your own planting box out of wood.
Scrub old pots with a 10% bleach solution before reuse. This will kill disease, pests, and accumulated fertilizer salts. Season new clay pots by submerging them in water for 15 minutes before you fill them with soil. This forces air out of pore spaces and will aid in keeping soil moist.
Most plants, especially annuals, require at least 5-7 hours of sun per day. Grow plants together that have the same light and moisture requirements. When planting large pots you may want to place the container on a caddy before you fill it.
