Phases of the moon most suitable for each activity in the garden

The moon, agriculture and the garden

The gravitational force of the moon influences the sap of the plants, affecting photosynthesis, the germination of the seeds, the movements so that it ascends or descends from the roots to the uppermost zone. For example, the phase between the crescent moon and the full moon is associated with the maximum point of sap concentration in the upper zone of the plants; the full moon affects in a greater development of the plant as far as its height, and during the new moon and the waning in the roots there is more concentration of sap. It is known that the moon in an upward position has a greater influence on the sap than on the descending one.

To know if the moon is ascending or descending we should only observe it in two successive days. The first day we will observe the moon and we will have a reference with respect to the height of it (for example a building) and the next day, but this time two hours later, we will again observe the height of the moon. If it is lower than the previous day then the moon will be in the descending phase and would be in an ascending phase if the moon is higher.

To identify the phases of the moon is simple. We can distinguish four phases: full moon (the moon is a white circle), new moon (the moon is totally black), quarter waning (when the moon forms a C) and crescent (joining the two points is formed the letter D ).


Lunar phases and the garden
full moon

In this phase, there may be an increase in pests. In addition, the sap is mainly concentrated in the foliage of the plant, which is why the foliage grows more quickly, although there is less fruiting than in other lunar phases.

Crescent moon

During this phase, the sap rises from the roots to the top of the plant. If you sow during this phase the development will be faster, in particular, the foliage will grow much more than the roots. That’s why it would be a good idea to favor the development of these. It is also more common for plants to be less resistant to diseases or pests.


New Moon

During this phase it is recommended to carry out tasks such as adventitious control, eliminating those plants that we do not want in our garden, and we will carry out other tasks of crop maintenance.

The waning moon


During the waning moon, we will notice that the plant has more splendor, and so much so that it tends to fructify much more. It is a period in which the sap descends to the roots.


Work of the garden for each lunar phase

For plants with a shallow root, the best time to fertilize is from a crescent moon to a full moon
If the plants have deep roots we will fertilize the new moon from the fourth quarter
Reproduction of the plants:

By cuttings and grafts: the stages between the crescent and the full moon are more beneficial because the cuttings sprout better and as for the grafts, problems are avoided by infections and facilitates healing.
Germinate seeds: the best moments are in crescent and full moon

If we want to favor that the plants have more fruits and more flowers, we will have to restrict the risks during the full moon and the growing quarter.


To prevent the plant or tree from losing sap, it is recommended to prune during the waning moon. And to facilitate that they return to sprout again it is better to prune between new moon and crescent moon. If we want the trees to develop more the foliage we will have to prune them in a new moon. In cases in which we want to reduce the development of foliage to favor fruiting, we must prune during the full moon or the quarter warning. In general, terms, if we want the plants or trees to give more fruit, we will prune in the first quarter, and if we want to reduce the growth we can in a waning quarter.

Spontaneous or unwanted plants:

If we want to eliminate spontaneous plants (badly called weeds), it is better to do it between full moon and waning quarter.


The plants or fruit trees are planted in a growing quarter, except for those that are gleaned that are sown in a waning quarter.
The plants or trees that we grow for their flowers or seeds will be sown in a waning quarter.
It is advisable to plant between growing moon and new moon those plants that grow and fructify on the earth and between the waning quarter and new moon the plants that fructify underground.
The seeds that take longer to germinate are sown in a waning quarter.
Seeds that germinate soon are sown in a growing quarter.

Harvest leaves, seeds, and flowers:

If we are going to dry them, it is better to take them between the waning moon and the new moon. If they are to be used at the moment we will take them between the crescent moon and the full moon.
