RIYADH: Caring for plants at home reduces stress and increases satisfaction. Gardening allows people to connect with nature and enjoy the beauty of their home garden.
However, it is important to use sustainable methods to ensure that plants are healthy, and the environment is protected from damage. Soil preservation and care are therefore very important for sustainable gardening.
The foundation of a successful garden is soil health. It is critical to take care of the soil before planting seeds by creating organic elements in the soil rather than relying on chemical or synthetic fertilizers.
Compost food scraps, garden waste and other organic products to improve soil fertility will provide nutrients to plants, increasing microbial activity and boosting the health of the soil.
“Synthetic fertilizers aren’t used in the Kingdom. It is rare. Most people use organic products such as animal waste mixed with food waste,” said Haitham Sharbaji, an agricultural technician who works in Riyadh.
Sharbaji, who operates his own nursery, explained how different plants require specific techniques.
When asked about examples of plants that are grown in hot, dry weather like in Saudi Arabia, he mentioned trees including poinciana, racosperma and oleander. According to Sharbaji, these species are especially suitable for the weather in Riyadh.
He highlighted the importance of planting trees in healthy soil.
“Firstly, the soil must be healthy and suitable for the type of plant you want to grow. For example, there are kinds of soil for indoor plants and others for outdoor plants,” Sharbaji said.
“Lighting is also important, as each plant differs in terms of its need for lighting.”
Another method gardeners can use to prevent soil depletion is controlling the rotation of plants. Rotating plants grown in different areas of a garden helps reduce diseases and pests, and prevents nutrient deficiencies.
In addition to changing the position of the plant, covering it with a layer of organic mulch like wood chips or leaves helps maintain soil health. This technique captures moisture as well as moderates the temperature of the soil, which in turn improves the structure of the soil. Over time, it enriches the soil with beneficial organisms.
Chemical pesticides are another tool to avoid or reduce, as they can harm beneficial insects, damage organisms in the soil and disrupt the garden’s ecosystem. Natural pest control methods like introducing insects such as ladybugs and lacewings are a useful alternative.
Water in Saudi Arabia is a precious resource for growing any plant, and using it efficiently is vital. An optimal way to regulate watering plants is to install drip irrigation systems to control the amount of water that is used and deliver it directly to the roots.
People should be mindful of the hot climate in the Kingdom, which may speed up the evaporation of water. Therefore, watering the garden late in the afternoon or evening hours reduces water loss because of low temperatures.
“Water is the biggest enemy for indoor plant soil. The soil that is prepared for indoor plants doesn’t need too much water because it can create toxic fungi,” said Sharbaji.
He recommends watering indoor plants according to room temperatures. Generally speaking, a person can water an indoor plant every 15 to 20 days, he added.
Excessive use of synthetic fertilizers can lead to nutrient imbalance and environmental pollution. It is best to test soil regularly to detect any signs of nutrient deficiencies such as decolorization of leaves or irregular shapes.
Synthetic fertilizers can be useful but only when necessary, and they must be used wisely. This ensures the plant receives the nutrients it needs while minimizing the risk of biomagnification — the increase in concentration of a substance in the tissues of organisms at successively higher levels in a food chain.
By practicing sustainable gardening practices, people can grow and protect their gardens while maintaining soil health. Healthy soil preparation, mulching and natural pest control methods are some examples of healthy gardening, keeping in mind that a thriving garden starts with the soil.
