What Does It Mean When a Plant Is Organic?
When a plant is labeled as “organic,” it means that it has been grown without the use of synthetic pesticides, herbicides, fertilizers, or genetically modified organisms (GMOs). Organic farming emphasizes the use of natural and sustainable practices that promote soil health, biodiversity, and ecological balance.
To be considered organic, a plant must meet certain standards set by regulatory bodies such as the USDA (United States Department of Agriculture) in the United States or the EU Organic Regulations in the European Union. These standards typically require that organic plants be grown in soil that has not been treated with synthetic chemicals for at least three years, and that any inputs used (such as fertilizers or pest control measures) be derived from natural sources and be approved for use in organic farming.

Organic farming practices also emphasize the use of crop rotation, cover cropping, and other techniques that promote soil fertility and reduce the risk of pests and diseases. Overall, the goal of organic farming is to produce healthy, high-quality crops while minimizing the impact on the environment and promoting sustainable agriculture.
Is Hydroponics an Organic Form of Gardening?
I think that, hydroponics itself is not considered organic gardening because it typically relies on synthetic fertilizers and other inputs that are not approved for use in organic farming. However, it is possible to grow plants hydroponically using organic techniques and inputs, which is known as organic hydroponics.
In organic hydroponics, the focus is on using natural and sustainable inputs that promote plant health without relying on synthetic chemicals. This can include using organic fertilizers derived from sources like fish emulsion, seaweed, or compost, and using natural pest control methods such as companion planting, biological controls, and physical barriers.
