How to care for weak small potted orchid seedlings? A full breakdown of care techniques

After weak small orchid seedlings are "hatched" from old, damaged growth tips and old pseudobulb tips, and after a period of growth, due to a lack of staying power, they always look stunted and unable to thrive. At this time, it is best to apply some very dilute foliar fertilizer every ten days to half a month (be careful it must not be too concentrated), to supplement their nutrition so they can grow strong and healthy.

There are two periods when weak small orchid seedlings are very difficult to grow, and special attention is needed:

The first is getting weak small seedlings through the summer. After weak small seedlings grow out, what they fear most is having to get through the hot, scorching summer, because after the new shoots of the orchid seedling emerge, new roots have not yet grown out, and there is not enough nutrition supplied. If they encounter weather above 30°C for a long time, the weak small orchid seedlings will certainly be damaged, so protective measures must be taken for weak small seedlings. Common protective measures: if you have an air-conditioned room, put them in the air-conditioned room. But be careful to avoid sudden changes between cold and heat, and maintain a certain air humidity (you can use a Hongyun fan to blow over the water in the pot to increase air humidity). If you do not have an air-conditioned room, you can put them in the bathroom and indirectly use a Hongyun fan to blow over pot water to increase humidity and lower temperature, ensuring the weak small orchid seedlings safely get through the summer.

The other difficult period to grow is winter. Weak small seedlings are also very afraid of overwintering. Winter weather is cold, and if insulation work is not done well, weak small seedlings are easily frozen to death, so insulation work is especially important. If you have an air-conditioned room, it is best to put the weak small seedlings in the air-conditioned room (and use the same method as in summer to increase air humidity); if you do not have an air-conditioned room, put them on an enclosed balcony, in the bathroom, or in a room, which is relatively safer. But pay attention to the moisture of the potting soil: it should not be too wet, nor too dry.

In cultivating weak small orchid seedlings, there are also two points worth noting:

First, after weak small seedlings grow out, it is best not to repot (turn) them in the first year, especially in winter. Because at this time the orchid seedlings are too small and the orchid roots are still few (some have no roots at all), if repotted, it is very difficult for them to adapt to the pot and problems easily arise. In addition, after many weak small seedlings grow out, because the seedling's pseudobulb is still very small, it needs to continue growing the pseudobulb the next year, so many weak small seedlings only grow pseudobulbs in the second year and do not send out new shoots.

Second, do not easily cut off old seedlings that are still green. Although most new shoots from pseudobulbs without old seedlings emerge earlier and grow faster than new shoots from pseudobulbs with old seedlings, after growing for a certain time, new shoots from pseudobulbs with old seedlings will quickly catch up with new shoots from pseudobulbs without old seedlings. New seedlings from pseudobulbs with old seedlings grow robustly, while new shoots from pseudobulbs without old seedlings grow weak. This shows that although it is only an old seedling, it can still provide nutrition to new shoots, so when repotting, do not easily cut off old seedlings that are still green.
