Propagated through grafting, a rose stem is fused to a stronger rootstock and allowed to grow in a coco peat mixture. Once the new shoots and roots are ready, the roses are planted in our greenhouses. Expert scouts regularly check for any diseases or pests, ensuring the plants are healthy and thriving.
We isolate our new plants for 3-4 weeks to get them ready to fully bloom in the greenhouses. This process is called hardening and helps prevent plants from being damaged or even killed by sunburn.
Freshwater is key to achieving high-quality roses. We have invested heavily in reverse osmosis systems for our irrigation water. State of the art machinery feeds all our greenhouses and propagation units with a fully computerised and automated fertigation system. This ensures EC and pH levels are consistent and optimal throughout, giving our roses a longer vase life.
At harvest time, the roses are carefully cut at the desired length, bundled in protective nets and put in a post-harvest solution. They are then transported to the intake hall via a banana system. Up to 500,000 stems are harvested every day.
The roses are bunched according to size and marked with a code – a crucial process to guarantee our customers receive excellent roses every time. The graded roses are stored in a cold room before being packed, weighed, labelled, and exported.
The roses are thoroughly inspected to make sure they meet the export quality criteria before storing them in a cold storage room to help maintain shelf life and avoid any bacterial contamination. After the cooling treatment, the roses are moved to a grading hall where our bunchers measure the bud size and stem lengths.
The roses are stored in a solution to prolong their shelf life. They are also kept in a protective sleeve and kept in 2 degrees Celsius surrounding to keep them dormant.
To retain freshness, the roses are delivered to the airport in refrigerated trucks and kept in 0cold rooms on arrival. This cold chain puts the flowers in a dormant state, keeping them fresh for longer.
At PJ Dave flowers we practice Integrated Pest Management (IPM), it is an effective and environmentally sensitive approach to pest management. Scouting information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, plants and the environment.
