Rosa post harvest advice

Roses are widely grown cut flowers used for ornamental purposes. After harvesting stems face problems such as vascular plugging, premature aging, ‘bent-neck’ and flowering stagnation. Insufficient hygiene, high temperatures and leaving the flowers dry too long will increase these problems.

After harvest certain processes within and outside the stem can cause vascular plugging, resulting in insufficient water uptake. It is most important to avoid vascular plugging and to stimulate the water uptake otherwise ornamental value and vase life will be reduced considerably. Hygiene measures, optimal temperature and a good post harvest treatment can effectively solve these problems. Florissant 600, 810 or 820 are the best post harvest products and specially developed for roses grown in tropical and sub tropical conditions. All products were tested and recommended by the Dutch flower auctions.

Florissant 600 is an Aluminium Sulphate based hydrating solution. It stimulates water uptake by neutralizing harmful processes within and outside the stems and avoids vascular plugging. It classifies as a pesticide and does not contain flower food, so does not evoke the opening of the flowers. Florissant 810 does not contain Aluminium Sulphate and improves the water uptake. Florissant 820 is very similar to 810 but also provides a little energy. 

Prepare the Florissant solution shortly before harvesting. Place the freshly cut flowers immediately in the Florissant solution and leave them in the solution for at least 4 hours.

Florissant 600 and 810 are excellent products to rehydrate roses after dry transport. It improves the water uptake and makes sure the foliage is fully turgid in a short time span. Florissant 820 is an ideal product to be used during storage Because it contains a little bit of sugar, to keep the metabolism going and give a small energy boost. 

Florissant flower food or Florissant 830 is to be used at a consumer level to open up flowers and to bring the flowers to full bloom.
