Many summer residents specially sow seedlings in common containers and then transplant them.
This method has one significant advantage: it is easier to create a suitable microclimate for seedlings in one container. But at the same time, experience suggests that picking is not always useful.
So, if there is a need to create and maintain a certain microclimate, then sow the seeds in containers.
When the shoots have two full leaves, you will need to pick them. But these are the very cases when this procedure does more harm than good.
Advantages of picking
In some cases, transplanting seedlings from a common container into separate cups stimulates the growth of seedlings.
But such stimulation is not indicated for all cultures. There are exceptions.
The harm of picking
If we are talking about peppers and eggplants, as well as cucumbers, then it is better to avoid picking.
The reason is that it takes them longer to recover.
Therefore, when planting seeds of these crops for seedlings, it is worth taking care of separate containers, and not relying on picking.
