AgriSearch: Growing Plants on Rooftops – Creating Green Spaces and Sustainable Farming
AgriSearch believes in the importance of homegrown, clean, and sustainable food, as well as creating green spaces and protecting the environment. Rooftop gardening has become popular as people realize these benefits.
Common plants grown on rooftops include shade-loving plants like paper flowers, lucky trees, and milkweed; herbs like lime and basil; and various types of vegetables such as cabbage and spinach.
However, rooftop environments can be harsh, with high temperatures, strong winds, and exposure to rainstorms and typhoons.
Therefore, planting and caring for rooftop plants require special attention.
Choosing the Right Plants
When choosing plants for rooftop gardening, consider the following:
- Select plants that can withstand drought.
- Choose plants that are healthy and can withstand strong winds.
Creating a Cool Environment
- Use sunshade netting in combination with insect netting or wind barriers.
- You can also use a mini greenhouse.
- Consider using a misting system for irrigation.
Choosing the Right Planters
- Choose larger planters to allow enough space for root growth and water retention.
- If using plastic planters, make sure they are UV-resistant.
- Avoid using wooden planters as they can be damaged by water.
Choosing the Right Soil
- Use soil with good durability for rooftop gardening and avoid using soil with excessive debris.
- Use soil with some organic matter to improve water retention.
- Include natural fertilizers like cow manure and goat manure in the soil.
- Regularly replenish nutrients for the soil.
- Remember to mulch the roots of all planters to maintain moisture, using materials like pine bark.
Choosing an Irrigation System for Rooftop Plants
Even if you have chosen the right plants, soil, and planters, it is not enough for rooftop gardening. Proper irrigation is crucial to ensure the plants thrive in harsh conditions.
Some common irrigation methods for rooftop gardening include:
- Hand watering with a hose. This requires having a ready water source on the rooftop. You simply attach a hose and nozzle to water the entire planting area.
- Misting for rooftop plants. Misting is highly recommended as it serves multiple purposes: maintaining moisture and providing a cool living environment for the plants.
- Drip irrigation, which delivers water directly to the root zone of each plant. It is the most water-efficient irrigation method you can use.
- Automatic irrigation timers are essential for both drip irrigation and misting systems. They ensure that the plants receive sufficient water at the right time.
- Consider using an automated fertilization system as well.
