Succinic acid will not help the orchids. The main myth of the Internet
Hello! Have you heard about feeding Phalaenopsis succinic acid? Throw to engage in an exercise in futility.
On the Internet you can deduct anything: the lady orchid revived after feeding yeast, and the man she finally blossomed after fertilizer children's urine. The latter is not exaggeration but a fact: there is video on Youtube.
But the reality of it has nothing to do. For the successful growth and flowering Phalaenopsis only need 2 things.
The first - is the abundance of light and always indirect. Overheating leaf moisture evaporates at lightning speed, and we see the burns.
Second - always wet substrate. This can only be bark or bark / moss, sphagnum moss. It is noteworthy that orchids grown in poor conditions, bloom profusely, but short-lived. extending the kind of mechanism, you know. Complete drying of the pot - it's just the stress, giving a reason for the multiplication by seed (flowering), but near the end of the existence of the plant.
Succinic acid is simply not needed and will not affect the growth and flowering orchids. All positive tests - just coincidence. Much more when yantarka not helped.
