The best time to grow according to the moon in September 2025

The influence of the moon on agriculture is an ancient tradition that has guided farmers from various cultures around the world. In September 2025, as in any other month, the phases of the moon play a crucial role in determining the best time to plant, transplant and harvest. In this article, we will explore how different lunar phases affect farming and provide a detailed guide on the best days to farm in September 2025 according to the lunar calendar.

The Influence of the Moon on Agriculture.

The belief that the moon affects plant growth is based on the idea that its gravity influences Earth's water, similar to how it causes tides in the oceans. Plants, which contain a large amount of water, are also subject to these gravitational forces. The theory suggests that during certain lunar phases, the movement of fluids in plants is affected, which can influence their growth and development.

Lunar Phases and Agricultural Activities.

Each lunar phase has a specific impact on plants and is associated with different agricultural activities:

New Moon: It is believed to be a good time to prepare the soil and compost. Plants planted during this phase tend to have balanced growth.
Crescent: This phase is ideal for planting fast-growing plants, leafy vegetables and plants that grow above ground. The sap is rising, which promotes plant growth.
Full Moon: Considered the best phase for harvesting fruit and vegetable plants, since it is believed that nutrients are at their peak. It is also a good time to water and fertilize.
Last Quarter: It is a suitable phase for planting roots and tubers, since the sap is descending, favoring growth underground. It is also a good time to prune and eliminate pests.

Cultivation Guide for September 2025.

New Moon (September 1 and 30).

During the new moon, energy is concentrated underground, making this an ideal time to prepare the soil and compost. It is a good time to plant plants that require an adaptation period before starting vigorous growth. Recommended activities:

Soil Preparation: Till and enrich the soil with compost and organic fertilizers.
Plant: Perennial plants, shrubs and trees.
Planning: Design the garden and plan future plantings.

Crescent Quarter (September 8)

In the crescent phase, plant sap is rising, which promotes rapid and vigorous growth of above-ground plants. Recommended activities:

Sowing: Leafy vegetables such as lettuce, spinach and chard. It is also a good time to plant aromatic herbs and medicinal plants.
Transplant: Young plants that will benefit from vigorous growth.
Irrigation and Fertilization: Increase irrigation and apply organic fertilizers to support growth.

Full Moon (September 15).

The full moon is known to be the best time to harvest, as nutrients are believed to be at their peak. This phase is also good for watering and fertilizing. Recommended activities:

Harvest: Fruits and vegetables, since they will be at their optimal point of maturity and flavor.
Irrigation: Increase irrigation to take advantage of maximum water absorption.
Fertilization: Apply liquid fertilizers for an immediate nutrient boost.

Last Quarter (September 23).

During the last quarter, the plants' energy is directed towards the roots, which is ideal for planting tubers and pruning. Recommended activities:

Sowing: Root vegetables such as carrots, beets and potatoes.
Pruning: Prune trees and shrubs to promote stronger growth.
Pest Control: Eliminate weeds and treat plants against pests and diseases.

Practical Tips for Growing According to the Moon.

To maximize the benefits of moon gardening, consider the following tips:

Keep a Gardening Journal: Record planting, transplanting, and harvest dates, as well as the corresponding moon phases. This will help you notice patterns and improve your planning.
Observe the Weather: Although the moon influences plant growth, weather conditions also play a crucial role. Be sure to adjust your activities based on the local climate.
Use Natural Tools and Products: Opt for hand tools and organic products to minimize environmental impact and promote healthy growth.

Testimonials from Farmers.

Many farmers and gardeners have reported positive results from following the lunar calendar. Here are some testimonials:

Case Study: Organic Farm in Cotopaxi.
On an organic farm in Cotopaxi, Ecuador, farmers have followed the lunar calendar for more than a decade. "We have noticed that our crops are more abundant and the plants are more resistant to diseases when we follow the lunar phases," says Juan Pérez, one of the main farmers. "Especially, we have seen an improvement in the quality of our fruits when we harvest them during the full moon."

Urban Gardeners Experience.
María López, an urban gardener in Quito, shares her experience: "I started following the lunar phases out of curiosity, and now I wouldn't change it for anything. My tomato and basil plants grew much faster and stronger when I planted them during the first quarter "In addition, harvesting during the full moon resulted in juicier and more flavorful tomatoes."

The Science Behind Lunar Gardening.
While lunar gardening has a solid foundation in tradition and empirical observation, the scientific community continues to debate its effectiveness. Some studies have found correlations between lunar phases and certain biological rhythms, while others have been unable to confirm these effects conclusively.

Scientific Research.
A study by the Institute of Lunar Agriculture in Germany suggested that lunar phases could influence the water content in plants, thus affecting their growth. However, the researchers also noted that more studies are needed to fully understand these mechanisms.

Critical Perspective.
Despite the lack of scientific consensus, moon gardening remains a popular and valued practice by many farmers. The combination of ancient wisdom and practical observation often leads to positive results, even if modern science cannot yet fully explain why.

Growing according to the phases of the moon in September 2025 can provide valuable guidance to maximize the growth and health of your plants. By following the lunar phases—new moon for preparing and planning, crescent moon for planting and transplanting, full moon for harvesting and watering, and waning moon for planting tubers and pruning—you can harmonize your garden with the natural rhythms of your environment.

Moon gardening is a practice that combines traditional wisdom with contemporary observation. Although modern science has not yet provided a definitive explanation, testimonies and practical experience suggest that there are tangible benefits to following the lunar calendar. After all, gardening is not only a science, but also an art, and the moon has been an inspiring muse for gardeners around the world.
