Slow ripening of fruits in a greenhouse often indicates that there is not enough carbon dioxide in the room.
The fact is that carbon dioxide is a compound that is of great importance in photosynthesis.
Plants need carbon dioxide just as people need oxygen.
High carbon dioxide content promotes early flowering and accelerated ripening of fruits.
How to increase carbon dioxide content
Getting more carbon dioxide into your greenhouse is very easy.
To do this, it is enough to install a container with cow manure in the greenhouse.
At the same time, the fertilizer should not take up the entire volume of the barrel. You need to leave room for water.
You shouldn't leave the mullein untouched. From time to time, the contents of the vessel will need to be stirred with a wooden stick.
Manure releases carbon dioxide. That is why plants will not have problems accessing the compound that is important for them.
Moreover, there will be a lot of carbon dioxide, due to which crops will bloom earlier and fruits will ripen faster. The chances of getting a bountiful harvest will increase.
