The propagation of the bulbs up to the final product is entirely managed in-house. Preferred Supplier Boers Amaryllis has two locations; one where the bulbs are grown and one where the cut amaryllises are cultivated.
At the bulb cultivation location, the bulbs go through the entire process to prepare them for cut flower cultivation. "The bulbs are sliced into segments for propagation, planted, harvested, and receive heat treatments. There is also a nursery where the bulbs are tested and assessed."
When the flowers meet the criteria, such as a straight stem, a good flower, and at least four tepals, they are added to the assortment in the other greenhouse. Erik Boers grows the heavier and more exclusive varieties, such as Red and White Lion, Lilac Favourite, Barbados, and Challenger.
The nursery in 's Gravenzande is very close to the sea, which provides a favorable climate due to milder summers and winters. This also influences the heating and cooling of the greenhouse, making it more environmentally friendly.
