Singapore’s climate supports various plants 

The temperature and barometric pressure are relatively constant throughout the year in Singapore, and the city-state receives a significant amount of rain. The typical temperature range for a room in Singapore is between 25 and 31 degrees Celsius. The temperature is most likely to be at its peak in the afternoon, while it will be lower in the morning and at night. The relative humidity fluctuates throughout the day, ranging from around 90 percent in the morning to approximately 60 percent in the middle of the afternoon.

The mean value is 84 percent. When there is continuous, heavy rain for an extended period, the relative humidity will often surpass 100 percent. There is a variance of 4 hPa in the pressure during the day regarding pressure. The highest possible pressure often occurs at 1100 and 2400 local time, while the lowest possible pressure typically occurs at 0500 and 1700 local time.

More than 2,000 native plant species are in Singapore’s 277 square miles of land, all of which have evolved to a tropical environment north of the Equator. Temperatures often reach 85 to 90 degrees Fahrenheit during the day, while nighttime lows average about 80 degrees. Plants in Singapore can survive despite the country’s high humidity and rains. Despite their difficulties, they can achieve satisfactory results to give Singapore its worldwide image as a Garden City.

Singapore container gardening: Steps to grow plants in containers

Choose an ideal container 

Containers can be bought, made, or repurposed to grow plants. Container material, size, color, and drainage are all significant considerations. It is important to choose the right container to protect the plant from stress caused by the container drying out too fast, restricting the plant’s root development, or roots lying in water and rotting. Your growth needs determine the kind of container you use.

More frequent watering is required for containers with pores and semi-pores than containers without pores. Plants that don’t need a lot of water should be grown in porous and semi-porous pots. Cacti and succulents benefit from the increased moisture loss.


All containers need drainage holes to avoid root rot. If the container lies flat on a firm surface like a patio, 14- to 1/2-inch drainage holes can be installed around the edge. Double-pot herbs or a fruit tree if the container has no drainage holes. Never use gravel or rocks to enhance drainage in a container. Soil water collects just above the gravel. Overwatering can cause soil to become saturated if there is not enough air space left in a potting mix to allow water to drain down into the gravel.


Unglazed ceramic pots should never be used for plants that will be left outside throughout the winter in container gardening. These pots will freeze and fracture if they contain any water. The soil temperature in outdoor pots can change by as much as 30°F throughout the day and night. Putting metal pots and tiny containers in direct sunlight might worsen this issue. Containers made of wood and plastic may be left outdoors all year round.

Without staining or painting, a cedar or redwood fence or deck can survive for around ten years before needing to be replaced. Even while heavy-duty plastic containers are the lightest, most moisture-retentive, and easiest to move near a protective wall for overwintering plants, they may lose their vibrant colors if left in full sunlight for an extended amount of time. Before using, rinse all containers with soap, warm water, and a non-bleach disinfectant.


When container gardening, we choose containers for aesthetics above horticultural necessity. For top-heavy, wind-exposed, or regularly moved plants, the weight of the container should be addressed. Porosity also matters. Overwatering container plants require a porous container. Underwatering container gardeners should use nonporous containers to retain moisture.

For two reasons, the size of the container should correspond to the plant’s growth needs. Restricted root development, in turn, reduces the growth of plants. Physical stress on the plant significantly reduces root and shoot development, known as root limitation. Second, the amount of fruit and flowers produced by plants grown in tiny containers similarly decreases. Consider both the container’s depth and its overall capacity.

On the other hand, Larger containers need less watering since they don’t dry up as rapidly. Annuals like lettuce, radishes, and scallions need a potting mix depth of 6 to 8 inches, while carrots prefer a potting mix depth of 10 to 12 inches for optimal growth. To cultivate most herbs, you need a 4 to 6 inches container diameter.

Select the potting mix 

It is essential to fill your pots with the soil of a good grade for optimal results. You shouldn’t use regular garden soil in your pots since it won’t drain correctly if you do. You can either purchase potting mixture from a gardening nursery or make your own by combining equal parts of organic compost, red soil, and vermicompost in a mixing container. When potting soil for containers, fertilizer and lime should be included.

The addition of fertilizer provides the plant with nutrients necessary for its development. Calcium and magnesium, two of the necessary elements, can be obtained from lime. In addition to this, it brings the pH of the soil into a range that is optimal for the development of plants.

Prepare the pot 

Be certain that the container includes a hole in the base that can be used for drainage. Since mud can clog the hole, placing some stones on top will ensure proper drainage. One can paint the pot and express individuality via different colors and patterns. Be very careful not to paint the inside of a container since the chemicals from the paint might potentially leach into the soil.

Remove the nursery plant

Before taking the plant from its packing at the nursery, could you give it a water spray? When the soil is watered, it becomes moist and compact, which reduces the risk of foot injury during the transplanting process. Remove the label of the package with the scissors. Take the packet out from below the plant, then use your hand to hold the plant’s base as you take the package out from underneath it.

If the plant is confined inside a container, tilt it slightly while keeping the top layer of soil supported with one hand. Now use the other hand to knock the plant out of its container gently. You can loosen the soil by tapping the edges of the container. Never remove a plant by its stem since the soil’s weight might separate the roots and stem, killing the plant.

Start planting 

Position the plant so that its topmost leaves are almost touching the surface of the container. The leftover space should be filled with soil. Shake the pot in a controlled manner to compact the soil down. If necessary, add some additional soil. However, you shouldn’t compact the soil by pressing down on it.

Allow some gap in it so that the roots can get some air. Growing plants in a container To prevent either water or soil from overflowing the container, fill the soil to within approximately 1 inch of the top. Last but not least, give the soil a few drops of water here and there to remain moist and porous.

Fertilise your plants 

To fertilize the soil to ensure that the plants in your containers get the nutrients they need for healthy growth. If the soil in the pots has not been fertilized, you can provide your plants with a head start by adding some organic compost to the soil. Before planting their greens, many gardeners sprinkle their soil with granular organic compost from the top down, and they repeat this process many times during the growing season.
