From planting to harvest 10-11 weeks.
From prune to harvest 9-10 weeks.
16-18 plants/m2 net or 2-2.25 plants/ft2 net.
Soil: Well drained, loose soil with no clusters, at least 25 cm (10 in.) deep.
pH: 5.5 to 6.5
Netting: 2-3 levels
It is advisable to do the pinch of the main stem at 10 cm height by removing just the apex. Chose the most vigorous stems (4 stems per plant) 3-4 weeks later and let grow.
Optional. Once the harvest has finished, the plants should be pruned leaving 1-2 cm of the stem over the soil. If no drip irrigation is available, do a higher pruning.
Always seal the wound to avoid infections.
Apply a daily average volume of 5 to 5.5 l/m2/day according to the soild’s humidity evapotranspiration conditions and the organoleptic evaluation. At the end of harvest, stop irrigation and restart one week after pruning.
A general fertilization formula can be the following:
N: 80 ppm; P: 40 ppm; K: 150 ppm;
Ca: 120 ppm: Mg: 50 ppm; S: 50 ppm; Fe: 2 ppm; Mn: 2.5 ppm: Cu, Zn and B: 0.2 ppm.
Maintain an electric conductivity below 1.3.
The optimal harvest stage is when one flower has its petals straight and when the petals start to separate. The maximum cut stage is when the inflorescence has 30% of open flowers.
POST HARVEST TREATMENT
Measure the hydrating water’s pH before applying any post harvest solutions. Use citric acid to bring the pH to 4.0. Place the flowers immediately after cutting in a solution with STC (20 cc/l dosis) for at least 2 hours. No cold room is necessary, but needs a fresh temperature room (T=15˚) protected form the wind and direct sun. Then, hydrate in Chryslar Professional 2 (6cc/l dosis) for 12 hours in a cold room.
PACKAGING AND STORAGE
After post-harvest treatment, pack 20 bouquets in a hamper box all placed in the same direction. Immediately after, store in cold room to maintain vase life. Store the hamper box vertically to avoid twisted stems.
