Inside a polyhouse, the air is warm and humid while the weather outside does whatever it pleases. Rows of long-stemmed roses grow here, protected and pampered for markets far away.

You may be wondering

What is fertigation and why is it used in polyhouses?

Fertigation means giving fertilisers dissolved in irrigation water through drip lines. Each plant receives nutrients directly at its roots in small, regular doses. This saves fertiliser and water and keeps growth uniform, which is important for producing evenly sized, high-quality flowers in a polyhouse.

Is protected cultivation only for roses?

No. Gerbera, carnation, orchids and many vegetables like capsicum and cucumber are also grown under protection. This course uses roses as the main example, but the skills of climate control, fertigation and hygiene carry over to other crops grown in polyhouses and shade nets.

Can I set up my own polyhouse in the future?

Many young farmers do. It requires planning, investment and careful learning, but government schemes sometimes support such structures. Gaining experience by working in an established polyhouse first helps you understand costs, crop scheduling and markets before starting your own unit.

What the course covers

• Understand protected cultivation and greenhouse structures
• Prepare growing media and planting containers
• Manage irrigation, fertigation, and greenhouse operations
• Grow roses using special horticultural practices
• Control pests and diseases and handle harvested flowers
