What does Bloom mean?
Bloom is a common term in the gardening community that can refer to:
- the blooming stage of a flowering plant
- the actual bloom itself
- the process or appearance of blossoming flowers
- a specific formula of plant nutrients (i.e. bloom nutrients)
- the waxy outer coat of some plants
When used in the context of a plant’s life stages, the bloom stage falls after the vegetative stage and is commonly referred to as the flowering stage. It’s not uncommon to hear a gardener say their plants have just entered the ‘bloom stage’.
In the context of hydroponic nutrient formulas, the products are often sold as ‘grow’ and ‘bloom’ formulas. With the grow bottles being used for vegetative growth, and the bloom bottles used during the flowering stage.
Bloom also shows up in products called bloom boosters, and in the phrase: ‘boosting the bloom.’
Physically, when used in reference to the waxy outer coat of some plants, a bloom is a part of the plant’s epidermis (outermost structure of plants) and the periderm (outer layer of plant stems and woody roots) texture of plants.
Like other parts of the plant, the epidermis cells are affected by the surrounding environment. Consequently, the epidermis of plants that grow in dry conditions are thick, while plants that grow in moist conditions are thin. In some cases this applies to the periderm.
To understand the connotation of bloom, it is important to break down the outer areas of plants. The outer layers of the plant includes the cuticle which attributes towards the cracks and ridges of plants and consists of portions known as cutin and pectic. These portions, mainly the cuticle, have waxy deposits of grarules and rods. This results in the bloom of plants and bloom is present in stems, leaves and fruits of plants.
