There is literature that suggests sunflowers are ethylene sensitive and would benefit from the use of an ethylene-action inhibitor, such as EthylBloc™ Technology. Use Floralife’s Hydraflor® 100 hydrating treatment for 1 - 2 hours (room temperature) immediately after harvest or overnight in a cooler. Transfer flowers into a holding solution of a properly mixed Floralife® Flower Food 300 or Floralife® 200 storage and transport treatment products. The flowers are then ready for shipment / storage.
Sunflowers should be open upon purchase (pollen should be visible).
Avoid flowers with yellow or dried leaves.
Processing: Unpack immediately. Remove foliage below the solution level. Recut stems.
If sunflowers have not been treated with an ethylene-action inhibitor such as EthylBloc® Technology, treat them as soon as possible. Use one of Floralife’s Flower Foods (see Holding Solution) to promote water uptake and hydration. This treatment will help increase bud opening, decrease flower wilting and fresh flower food keeps flower stems free flowing.
There are two Floralife® hydration products to consider:
1. Hydraflor® 100 hydrating treatment: A concentrate, generally recommended for maximum results, especially with hard-to-hydrate flowers like roses. The treatment is usually for one half hour at room temperature.
2. Floralife® Quick Dip 100 instant hydrating treatment: A ready-to-use version that requires no mixing or measuring. This quick one second dip may be more suitable to retail flower shops.
Flowers should then be placed into a holding solution of a Floralife® flower food.
Use fresh flower food at the recommended rate: Use Flower Food 300, 200, Clear 200, or Clear ULTRA 200 storage and transport treatments, or depending on water test results, Special Blend 300 for Hard Water or for Pure Water.
To have water tested, send a plastic quart bottle of your water to:
Floralife | 751 Thunderbolt Drive | Walterboro, SC 29488 | Attn.: Laboratory.
Hold flowers at room temperature for 1 - 2 hours prior to storage in cooler or designing. As a finishing touch to any floral design, spray Floralife® Finishing Touch hydration and protection spray over entire project.
Use D.C.D.® Cleaner Solution to clean buckets, vases, coolers, etc. D.C.D.® is specifically formulated to kill microbes over an extended period.
Always give a packet of a Floralife® Flower Food with your designs. One liter packets treat one quart of water.
Ethylene Sensitivity: Varies depending on the cultivar. Some cultivars are ethylene sensitive.
Vase Life: 5 to 14 days depending on the cultivar and postharvest care.
Storage Temperature: 34 - 36˚ F cooler / 75 - 85% humidity.
May be due to age of flower or improper storage and handling. Flower will last longer than the foliage: as foliage dies remove the leaves.
May be due to improper stage of harvest, or flower may be dehydrated. Recut the stem under water and hydrate the flower (see above section on “Hydration”), then place in Floralife® flower food.
