Influence and characteristics of the Moon on December 17, 2026

At midday, the Moon is in the Pisces ♓ (+).

It is considered one of the most productive signs of the lunar cycle. Harvests will be abundant, as in Cancer, but stored crops will not last very long. In Pisces it is better to deal with sowing and transplanting any plants, planting on a permanent place of grown seedlings, loosening, moderate rooting and watering. Do not treat plants from diseases and pests, rejuvenating and corrective pruning.

The middle of the day falls on the 10 lunar day (+).

It is a very favourable day for planting and transplanting trees and shrubs in the garden, also for planting seeds, seedlings and various saplings. Prepare, root and graft cuttings, actively water and fertilise garden plants, but do not rush into cutting and pruning.

Current phase – First Quarter at 5:43:09 am (+).

A favourable time to sow seeds that will produce above-ground fruit plants. It is also a good time to harvest mature crops.

Influence of the day of the week – Thursday (+).

Thursday is controlled by the giant Jupiter. This is the best day for weeding and transplanting plants. However, any other business will also go well. If you don't have a plan, trust your intuition to tell you what to do first today.
