What causes flowers to open
When you grow flowers in your garden, you most probably want to make sure that they are healthy and produce plenty of beautiful blooms. Even if your plant produces many flower buds, they won’t put on much of a show if they don’t open up and show off their gorgeous petals. The same can be said for cut flowers. When you order flowers from your florist, it’s best to choose flowers that are partially opened. If the bud is tightly closed when the stem is cut, it may never open fully or even at all. That said, if you buy flowers that are already fully opened, they will not last as long as you’d like. So, ideally, you should select flowers that are partially opened. This way, you know they will open fully and you get to enjoy them for that much longer.
The first thing to remember is that plants need flowers to facilitate reproduction. Thanks to the wind and insects like bees and butterflies, plants are able to spread their seed quite effectively. Even ants play an important role in flower reproduction. Peonies, for example, will not open until ants enter the flower. So, if it wasn’t for these tiny insects, we would never be able to enjoy the beauty of these stunning blooms.
Just like humans and animals need food to survive, so too do plants and flowers. The only difference being that plants bloom during certain seasons and they also have dormant periods. During the blooming season, they will require extra food and water whereas, when they are dormant, they don’t need as much nutrients since they do not grow during this period. Plants are sensitive to the weather and temperatures. When temperatures are too low or high, they will not bloom. Only when their needs are met will they produce ample flowers. If you cut flowers while they are still partially closed, you will need to make sure that your flowers have a source of food. The best way of doing this is by adding flower food to the water in your vase. This flower food helps give your cut flowers the energy to open fully and it also helps slow the growth of bacteria in the vase water.
Plants absorb carbon dioxide, water, and nutrients from the soil. Through photosynthesis, they combine the nutrients absorbed with the energy of the sun in order to produce food. If any of these factors were removed, plants would not thrive and they certainly would not bloom and produce flowers or fruit. That said, cut flowers need water and nutrients but they should not be exposed to direct sunlight since it will only cause the flowers to wilt and die.
