Delphinium / Larkspur are ethylene sensitive and benefit from an anti-ethylene product treatment such as EthylBloc™. Ethylene will cause shattering (excessive dropping) of the florets. To protect flowers from ethylene damage use an anti-ethylene product to treat flowers as soon as possible after harvest. After cutting, place Delphinium / Larkspur stems in a solution of HydraFlor® 100 for 1 hr. (or up to overnight at 34 - 38˚ F). Transfer stems to a solution of one of the Floralife® 200 formulas for storage. Please contact Floralife for specifics.
Wholesaler / Retailer Recommendations
Ask: Has product been pretreated with a commercial anti-ethylene product, such as EthylBloc™ or EthylGuard? Has the product been stored and under what conditions?
Rinse stems of any dirt or debris. Remove foliage below water level. Recut stems.
Even if delphinium / larkspur have been treated with an anti-ethylene product such as EthylBloc™, treat them again, as soon as possible. Use one of the Floralife hydration products to promote water uptake and hydration. This treatment will help decrease flower wilting and helps keep flower stems free flowing.
There are two Floralife 100 products to consider:
1.) HydraFlor® 100: 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.) Quick Dip 100: A ready-to-use version that requires no mixing or measuring. This quick one second dip may be more suitable for use in retail flower shops.
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 (2 - 4 hours if flowers are limp or exhibiting bent neck) prior to storage in cooler or designing. As a finishing touch to any floral design, spray Finishing Touch hydration and protection spray over entire project.
Always give a packet of a Floralife Flower Food with your designs. One liter packets treat one quart of water.
Shattering (excessive dropping of florets)
Can be caused by drying out, rough handling, old age, external exposure to ethylene and / or flower producing ethylene due to stress. Check with supplier on product harvest date. Make sure a proper anti-ethylene treatment is performed, fresh flower food is used and rough handling is avoided.
