There are two main growing methods of floriculture production (growing cut flowers and foliage) : inground, and hydroponic.
Inground plants are grown, as the name suggests, in the ground. This could be soil, or a commercial organic substrate such as potting compost. Some plants are grown out in fields or plantations – trees and large shrubs which produce flowering and foliage branches are often grown like this; as are some bulb flowers.
Other crops may be grown under shade screens, hoops, polytunnels, or in glasshouses. Growing under cover can provide
- shade to prevent scorching
- protection against pest attack
- protection against weather incidents, eg hailstorm
- regulated climate control
This is a way growing plants in water, not soil, with added nutrients for growth. Sometimes a stable growing medium – perlite, gravel, mineral wool, expanded clay pebbles or coconut husk – is added. The plant can take up the nutrients it needs without the need for soil.
This can be a more efficient method of growing for some crops, as it
- produces more plants per hectare than conventional means
- enables control of temperature and humidity
- requires much less water (paradoxically) than soil-grown crops
If you are interested in growing cut flowers or foliages commercially then state or regional peak bodies and horticultural organisations can help with information and advice on suitable crops to grow and how best to grow them.Where do we grow flowers in Australia?
