Every nursery is unique. Climate, cultivation technique, and the desired flowering date all determine the best preparation for a successful crop. That’s why, at Holland Bulb Market, we tailor the preparation of flower bulbs entirely to the customer’s specific situation.
The grower provides us with all relevant details: the cultivation method (open field, crates with compost, or hydroponics), greenhouse conditions, the desired bloom period, and the selected varieties. Based on this information, we create a customised preparation schedule, precisely defining when the warm phase begins and how long the bulbs will be cooled in our computer-controlled preparation rooms.
Depending on the cultivation method, variety, and desired flowering date, we prepare the bulbs at either 5°C or 9°C. In our storage facilities, each batch receives a customised treatment, precisely tailored to the grower’s cultivation schedule. This ensures predictable flowering and gives the crop a strong and uniform start.
But our service goes far beyond the delivery of well-prepared bulbs. Each shipment is accompanied by a complete forcing schedule – a practical step-by-step guide that outlines when to plant the bulbs, how long the rooting period lasts, and when they should be transferred to the greenhouse for forcing. This helps growers optimise their planning and ensures predictable, uniform production.
To actively monitor quality and progress, we conduct a parallel cultivation in our own greenhouses using the exact same batches as our customers. This allows us to closely follow development and provide timely guidance if deviations arise.
We also benefit from exceptional expertise through our close partnership with our sister company Holland Bolroy Markt B.V., renowned globally for its extensive tulip collection – the largest of registered varieties in the world. This collaboration grants us access to in-depth cultivation knowledge and innovative varieties.
With our combined hands-on experience, cultivation support, and specialised knowledge, we provide not only premium starting material but also expert advice. Clear communication is key, and we are always ready to support our clients in achieving consistent, high-quality results – backed by Holland Bulb Market and the world’s leading tulip specialist.
All tulip bulbs from Holland Bulb Market are inspected for the G-stage – the developmental phase in which the flower inside the bulb is fully formed. This moment is critical, as it determines the optimal timing for the start of the cold treatment. By identifying the G-stage precisely, we ensure a predictable bloom that aligns seamlessly with the grower’s production schedule
While tulips are a key crop in professional cultivation, Holland Bulb Market’s expertise goes far beyond. We also have extensive experience with hyacinths, both in bulb preparation and crop support. Successful hyacinth cultivation depends on precise pre-treatment, where the right balance of warmth and cooling influences bulb development and rooting strength.
Thanks to long-standing partnerships with specialised hyacinth growers, we understand the specific needs of each variety—whether grown for pots or as cut flowers. We provide full support, from product selection to tailored cultivation advice. Every delivery includes a custom forcing schedule that outlines exact planting times, rooting duration, and when to transfer bulbs to the greenhouse.
This combination of product knowledge, hands-on guidance, and strict quality control ensures our hyacinth bulbs grow into premium flowers—perfectly aligned with both grower needs and market expectations.
Interest in amaryllises continues to rise—a development that aligns perfectly with our expertise, thanks to our close partnership with sister company Park Amaryllis. This specialist focuses entirely on sustainable breeding and propagation of premium amaryllis varieties. These varieties are ideally suited for pot cultivation and dry-sale markets, and also perform exceptionally well as cut flowers—even under hydroponic conditions.
We share extensive knowledge on iris cultivation through close collaboration with our sister company Iris Nova, which specializes in production and breeding of irises for the professional market. This allows us to advise growers on optimal preparation, storage conditions, and ideal greenhouse growing schedules to ensure consistent, high-quality crops every season.
Lilies remain a key product in professional cultivation, especially for cut flowers. Our expertise in preparation and understanding of varietal requirements supports growers in achieving strong starts and market-aligned flowering.
For freesias, we provide suitable planting material and precise cultivation advice, focusing on careful preparation to produce long, sturdy stems and flowers with excellent vase life.
Narcissus also play a significant role, particularly in early greenhouse cultivation. By combining proper bulb preparation and timing with climate control, we help growers maximize crop potential from root development to perfect bloom.
