Have you ever wondered how to keep flowers fresher longer or what role natural solutions play in their development and preservation?
In a context where sustainability is becoming increasingly important, knowing the most effective and environmentally friendly practices to improve the quality, durability, and longevity of flowers is key for both producers and florists and hobbyists.
1. Post-harvest nutrition and preservation: an essential combination
The quality of flowers can deteriorate rapidly due to heat, dehydration, and mechanical stress. Several studies have shown that the use of preservative solutions that inhibit ethylene synthesis can extend their shelf life. In particular, the application of sodium chloride cobalt (Co) in concentrations of 0.1 to 0.2 mM in varieties like Lilium 'Star Gazer' y 'Star Fighter' It has been shown to delay floral senescence, improve water absorption and preserve fresh weight.
When combined with a carbon source like sucrose, this solution also improves SPAD (leaf health indicators) and overall hydration. Divalent cations like calcium and magnesium, present in these solutions, promote water transport and reduce cellular resistance, facilitating longer flowering.
2. Microalgae: a natural source of phytohormones
The use of microalgae extracts during the growth and flowering phase has proven to be highly beneficial. These extracts are rich in phytohormones such as auxins, cytokinins, and gibberellins, which stimulate cell division, improve flower formation, and delay senescence. In particular, the cytokinins present in algae contribute to prolonging post-harvest life by inhibiting premature aging of flowers.
3. Ideal pH of the substrate
Soil pH is a key parameter for the nutrient absorption and overall plant healthIn most ornamental species, the optimum pH range is between 5.5 and 6.5, slightly acidic, which allows for adequate availability of macro- and micronutrients. Outside this range, the efficiency of the root system decreases and deficiency symptoms may appear.
4. Green solutions for flowering management
The use of environmentally friendly products is on the rise. Compounds such as peroxyacetic acid They act as effective fungicides and bactericides, easily decomposing into water and oxygen without leaving toxic residues. Likewise, the use of hydrogen peroxide As an alternative to sodium hypochlorite, it allows you to maintain cleanliness without compromising sustainability.
Also, add sugar to hydration solutions improves floral opening and enhances colors, offering attractive aesthetic results and prolonging freshness.
5. Cultifort Formulas: Innovation in flower care
BVC 2021 It is an advanced solution that combines amino acids, reducing sugars and seaweed, providing plants with all the essential nutrients for strengthen your system and prolong the life of the flowers. This product increases the flower resistance to low temperatures and adverse weather conditionsWhile improves flowering and prevents senescence.
FOLIQUINO It is a natural complex aluminum lignosulfonate base, offers superior penetration and translocation through both the foliar and root routes. Thanks to its action, Plants can access nutrients more efficiently and better defend themselves against stress.
SPIRALIS Long Life It is a phosphopotassium solution specially formulated for stimulate the salicylic acid pathway in plants, which promotes disease resistance and extends the post-harvest life of flowers.
