The recommended stage of harvest is when buds are just showing color. Our recommendation is to ship flowers dry and cool. If shipped in a solution, use Floralife’s Hydraflor® 100 hydrating treatment for ½ hour immediately after harvest and then transfer flowers into a properly mixed solution of Floralife® 200 storage and transport solution. If tulips are going to be stored dry, best results are obtained when flowers are stored vertically, with bulbs on, at 33 - 36˚ F.
Ask variety name. Different varieties have different flower qualities. Perform a simple vase life test to determine which varieties tend to last longer and are more disease resistant.
Request the specific cut stage from grower.
Look for flowers just beginning to show color.
Processing: Unpack immediately. Wash soil and sand off stems. Recut stems. Cut off white fleshy basal portion of stem. Use clean cutting tools.
Use Floralife Hydraflor® 100 hydrating treatment for ½ hour at room temperature (see below) to promote water uptake and ensure proper hydration, so that tulips become firm and stems remain free flowing. Floralife® PAL 100 treatment can be added to hydration solution to help with healthy foliage.
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 if flowers are limp) prior to storage in cooler or designing. Keep stems wrapped in paper or plastic sleeves to keep stems upright. Avoid excess moisture on flower heads and stems as this may contribute to the growth of Botrytis. Cutting a slit just below the flower head in the tulip stem has not been proven to keep the flower from opening.
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.
Flowers “blow” open too quickly.
Likely due to being held at warm temperatures. Hold at 34-36˚ F. If displaying outside cooler, try to hold at a cool temperature at night. Also, there are different varieties that “blow” open more quickly than others.
Stems continue to “grow” (elongate) after harvest.
Keep flowers at the cool temperature listed above. Try to insert tulips into arrangements at the latest time possible or place them deeper into the design.
