As you prepare to enjoy a cool autumn evening in the tropics, the sea is a veritable garden.
As it grows and develops, it produces a lush array of plants, from wild lettuce and cabbage to tropical fruit and coconut palms.
But it is the ever-evolving sea that is the key to keeping these gardens alive.
Here are some tips on how to keep your tropical garden healthy.
Keep your sea grass under control 1.
Sea grass is an invasive plant and can make a garden seem more invasive.
Its roots, which are also edible, make up a key ingredient in some tropical garden plants.
To keep sea grass in check, plant it under cover to ensure its roots do not interfere with other plants.
“It’s important to keep sea flowers and sea algae from competing with your sea vegetation,” says Mark Jones, a botanist at the University of Otago.
“If you can keep it in check by keeping it in a shady place away from water, then it can be quite a healthy plant.”
Try to keep the soil acidic If you live in the Southern Hemisphere, it is possible to get away with an acidic soil.
However, if you live elsewhere in the world, such as the tropic, then this is not advisable.
If you do not want to put sea grass and other sea plants under cover, it may be possible to add calcium carbonate to the soil.
This will help reduce acidity.
“Sea grass can absorb nutrients from the water and the plants that are under it,” says Jones.
“Calcium carbonate will increase the uptake of nutrients from soil and the water, so this will keep the seaweed from absorbing nutrients from other plants.”
Plant in the early spring to maintain the garden environment The early spring is the time when seaweed and other plants grow best.
The early summer is when sea grass can flourish and create lush gardens.
This time of year is also when you will have more space to plant, and will have plenty of nutrients available.
Jones recommends planting the garden at the end of the growing season.
“There are many benefits to planting in the spring,” he says.
“This gives the plants a chance to grow and mature, and also gives the sea grass a chance for oxygen to reach the roots.
So the plants have a chance of developing.”
Avoid watering the plants too much In a tropical garden, the plants need water to grow.
This is because sea grass needs more water than it gets from the atmosphere.
However if you are using a container that is not meant to hold more than about a metre (yards) of seawater, Jones recommends watering it regularly to keep it at a steady pH.
This helps ensure that the seaweeds stay healthy and in good condition.
Grow a small area around the plants You can also grow a small, rectangular area around your plants to keep them hydrated.
This can help keep them warm and dry during the cold winter months.
Add lime to your garden lime is an alkaline soil ingredient that can help balance out the acidity of the sea vegetation.
However lime needs to be added in small amounts, and only when needed.
To get the right amount, add about a teaspoon of lime to a pint of water every day.
This mixture should be placed in a plastic container with the lid closed.
Use a mulch to help keep seaweed out of the garden This is a great way to make your garden a little more aesthetically pleasing.
“I have always been fascinated by the effect seaweed has on the environment,” says Tom Johnson, a marine biologist at the Australian Museum.
“As you grow in the sea, the seawead absorbs some of the carbon dioxide released by the sun and releases it back into the atmosphere, which is one of the primary reasons seaweed grows in the first place.”
Keep the garden cool This is not a problem for many people, as sea grass thrives in the cooler months of the year.
However in the warmer months, it will need to be kept cool to maintain its health.
To do this, place the garden in a well-ventilated area away from the elements, such that it cannot get too hot or too cold.
Jones suggests planting your garden at a location where it is not too hot in the summer and a sunny location in the winter.
“The cool temperatures can keep the seagrass healthy and make it more attractive to insects,” he adds.
They will feed on the algae, which will help maintain the seawod.”
Add more nutrients to your soil The nutrients that are needed to make seaweed grow will depend on how much light your home gets, says Jones, but the main nutrients that can be added to your soils include calcium carbonates and nitrogen.
“CaCO3 and nitrogen can both be added with the help of the plant,
