HONOLULU (KHON2) -- Imagine you’re walking through your backyard, and you see all sorts of plants, including some weeds. While many people think of weeds as unwanted plants that need to be removed, they actually play important roles in our gardens, lawns and backyards.
Let's dive into why having weeds can be beneficial, especially in a place as unique and beautiful as Hawaiʻi.
First, weeds can help the soil.
Some weeds have long roots that dig deep into the ground. These roots break up hard soil and bring nutrients closer to the surface, which helps other plants grow.
For example, the indigenous plant ‘ihi (Portulaca villosa), which some consider a weed, has roots that can help improve soil health.
Weeds also provide food and shelter for insects, birds and other animals that assist with the ever-important pollination process.
In Hawaiʻi, native insects like the Kamehameha butterfly depend on certain plants for survival. The butterfly lays its eggs on māmaki (Pipturus albidus), a plant that some might think of as a weed but is actually crucial for the butterfly’s lifecycle.
Another interesting aspect is that some weeds are edible or have medicinal properties.
For instance, pōpolo (Solanum americanum), often seen as a weed, has berries and leaves that have been used in traditional Native Hawaiian medicine. These plants offer natural remedies and can be a valuable resource if you know how to use them safely.
Here’s a list of some indigenous plants to Hawaiʻi that are often considered weeds and their benefits:
- ‘Ihi (Portulaca villosa): Improves soil health with its deep roots.
- Māmaki (Pipturus albidus): Essential for the Kamehameha butterfly.
- Pōpolo (Solanum americanum): Has medicinal properties and can be used in traditional remedies.
- Pili Grass (Heteropogon contortus): Helps prevent soil erosion with its dense root system.
Additionally, weeds can tell us about the health of our garden.
Certain weeds grow in specific conditions; so, their presence can indicate if your soil is too acidic, too dry or lacking in nutrients. This information can help you take better care of your garden.
So, the next time you see weeds in your backyard, think twice before pulling them out. They might be doing more good than you realize, especially in the diverse ecosystem of Hawaiʻi.
