The recipe for happiness for orchids is simple: create an eternal summer, diffused sunlight, and humidity. Two conditions contribute to this:
Orchids do not tolerate direct sunlight, but also do not like deep shade. The best place for them is windows facing west and east. Daylight for orchids should last, on average, 12 hours. So from September to March, you will have to use special lamps, and the rest of the time — shade with blinds, curtains, or shutters on the window.
Orchids are afraid of drafts and hot air from batteries. Different types of flowers require a special temperature:
- for phalaenopsis, dendrobiums, and cattleya the optimal daytime temperature is 25-32° C and 18-20° C at night;
- odontoglossum, Miltonia, and other mountain species luxuriate during the day at 20-22° C and at night 15-18° C;
- dendrobiums, lilies, and paphiopedilums feel better at 19-22° C during the day and 15-18° C at night.
How to replant an orchid and when
Replanting orchids is necessary every one or two years. The following tips will also help if you wonder how to regrow an orchid. The best time for this is in spring when the plant is growing.
- Release the roots of the plant from the old pot by cutting or carefully breaking.
- Inspect the roots, wash them, and dry them. Remove rotten or dried with a fire-heated knife, secateurs, or scalpel. Powder fresh slices with cinnamon powder or charcoal.
- Place the plant in a pot with the prepared substrate, straightening the roots and lightly covering them with the mixture. If the plant has a corm, it should protrude above the soil surface.
- When replanting, place a piece of foam under the base of the stem. It pulls water on itself and dries quickly. Orchids will not suffer from excess moisture after watering.
- Put the replanted plant in a beautiful pot or in a decorative pot to please the eye.
- Put it in a shady place for a week and do not water during this time to adapt.
What kind of pot do you need for an orchid?
Replanting orchids into a clay or ceramic pot with soil is a bad decision. The plant will die due to root rot. Under natural conditions, the orchid grows on trees and uses its roots for photosynthesis. It is fed by water when it rains.
The ideal utensil for replanting is a box made of wicker or a box with large slits made of wooden slats. The third option is a special pot for orchids made of transparent plastic. You can make more holes in the bottom and walls of the pot so that the roots are well ventilated. Drainage from perlite or small rubble should occupy not less than a third of the height of a flowerpot.
How to water an orchid
The principle is simple: less is better than more. Orchids easily tolerate over-drying of roots, but excess moisture will destroy them. Water temperature should be 3-5 degrees above room temperature.
