Water Gardening

STUDY WATER GARDENING AT HOME or ONLINE

"This is the first correspondence course I have done and I have thoroughly enjoyed it and I just wanted to say a big THANK YOU. I appreciate everyone's effort in such a professionally-run organisation with seamless administration. The office staff's happy can-do attitude, their fast responses to all queries, tutor Shane Gould's quick turnaround in assignment marking and his supportive and motivational feedback and last but not least, the sound subject guides. Most importantly I hope my thanks and appreciation can be communicated to all the staff who have supported me long the way of my learning! I work full time and study on the weekend but really don't stop thinking about what gardening solution I need in order to answer my assignments every day of the week. Thank you for such a great learning experience and I cant wait to start the second half of my course!!"

Tips for Managing Life in the Water Garden

Algae
You will get living things in water very easily but they might not be the living things you want. Algae will grow wherever there is water, light and a few nutrients. If you have fish, snails or any other types of animals, or even leaves and dust blowing into the water, these will provide nutrients, so algae will inevitably grow. Aquatic animals will eat the algae, and if you have the right balance of animals and plants, they will prevent excessive algal growth.

If you want crystal clear water, you must keep the algae under control, and remove any other contaminants such as dust, which might enter and discolour the water. Filtration and/or other treatments such as chlorination or bromination might be necessary for this. If you want fish in the water, chemicals can cause real problems and while it is possible to do this and still have very clear water; that can involve a lot of expertise and expensive equipment to perfect and control.

Fish
Fish need water with air in it. If you want fish, you need water to splash or move, because that's how it becomes aerated. A waterfall, cascade or fountain can be very beneficial to fish, and help improve their feeding, hence keeping algae down and water clarity up.

Mosquitoes
Mosquitoes and other undesirable insects can breed in water or moist places around a water garden. In areas where serious mosquito-borne diseases are common (eg. Malaria), it is extremely important to keep these insects in check. Fish or other insect-eating animals in the water will help reduce their numbers. If the water is chemically treated, or sprayed periodically, this can also keep insects at bay.

Wildlife
Attracting wildlife (birds, snakes, toads etc) can be a disadvantage especially with small children and pets. Birds are a wonderful feature in a garden but snakes are generally not welcomed.

If you have a lot of mulch near a pool, spa or pond, small animals such as centipedes which breed in the moist mulch will find their way into the water. Snakes, toads and lizards are sometimes found trapped in a pool or spa. (A beach area or shallow shelf surrounding your water feature may allow them to escape.) Water birds, such as ducks, will sometimes take a swim in a swimming pool and leave their feathers or worse (excreta) behind.

Plants
One of the wonderful things about water is that it can allow us to grow all sorts of wonderful plants that are otherwise not possible in the garden. 

Ideally, plants should be selected to try and reproduce the effects seen in nature. Some plants require shallow water, others deeper water. Some float on the surface, some grow submerged in the water, while others grow in the moist soil conditions beside a pond. You are best to visit a specialist supplier of water garden plants to get an idea of those suited to your area.

Oxygenating plants
Plants that are completely (or almost completely) submerged are essential to the health of fish and other water life. If you have too few of these plants, fish and snails will eat them faster than they can grow. If you have too many, they can take over, and clog up a pond. It is important to get advice about what and how much to use from a water garden expert when starting up.

Plant oxygenating plants by burying the base in either compost or mud, and then putting a rock and sprinkling of gravel on top to prevent fish stirring up the material at their base. Eel Grass is one of the most commonly grown varieties. With ribbon like pale green foliage it is well suited to temperate but not extremely cold areas. Potamogeton crispus, another alternative, with slender dark green leaves, is suited to most climates.
