How Often to Water Orchids? Master the Correct Watering Frequency

Generally speaking, orchids need water once a week in spring and autumn; once every two days to a week in summer; and about once every two weeks in winter. However, because the climate varies from place to place and the varieties differ, the watering frequency should vary as well. Therefore, it is better to judge whether to water based on how dry or moist the soil is. The methods for judging include the stick insertion method, the tube insertion method, and the surface observation method.

1. How Often to Water

Generally speaking, the frequency is most closely related to the season. Spring and autumn are about the same, roughly once a week. Summer requires more frequent watering, once every two days to a week; if there is rainwater, you can use rainwater first, but the plants should not be drenched with too much rainwater. Winter requires less frequent watering, about once every two weeks. However, this is only an approximate frequency range, and the actual situation is more complex. Different regions have different climates, and the varieties differ as well, so relying entirely on this is not scientific. It is best to decide whether to water based on the specific dryness or moisture of the soil.

2. Methods for Judging Whether the Soil Is Dry or Moist

(1) Stick insertion method: Use a toothpick to judge. First break off the tip of a toothpick to avoid damaging the plant. Once it is prepared, insert it into the soil about four to five cm deep. Wait five minutes, then take it out and observe. If there is no moisture on it, it means the soil is already dry. At this point, you can water.

(2) Tube insertion method: The principle is similar to the previous method. Poke five or six small holes in the lower part of a plastic tube and cut the lower half into a slanted surface. Then insert it into the soil eight to ten cm deep. After five minutes, pull it out and check whether there is moisture. If there is none, you can water.

(3) Soil surface: You can also observe the surface of the soil. If it has just turned pale, there is no need to water yet. Wait a day or two before watering.
