Now in flower/bud
Orchid in bud
As soon as a stem emerges and announces the next flower, you need to be patient and wait for the coming splendour. This may well take a few weeks. However, excessively dry indoor air can jeopardise the buds. If the air humidity is below 50% or the plant is directly next to a radiator, it is advisable to spray the smallest buds with water every day to prevent them from drying out. However, buds may also fall off due to too frequent watering.
Orchids in bud
The production of flowers is an exhausting event for a plant that should not be underestimated, as it requires energy and nutrients. However, too much moisture causes roots to become sickly. This has a negative effect on the supply of water and nutrients, and therefore on the overall health of the plant and ultimately also on the success of flowering. But if this is not the reason, then, as with dormant flowers, location-related factors - for example, ripening gases from a nearby fruit bowl, solvent vapours in a newly renovated room or a nearby gas connection - can also be a source of problems.
In any case, your orchid will be happy to have a nice sunny and warm location to quickly turn its buds into enchanting flowers. Incidentally, now is also not a good time to repot them. Wait until the flowering phase is over and only then give it fresh substrate and more legroom in a new pot. Interesting fact: The flowering phase of an orchid has a fascinating regularity, as the oldest and plumpest buds always open before the smaller, younger ones at the tip of the stem. These take their time to develop fully, while others are already open. After all, the bud that blossomed first will also wilt the earliest.
