Passion for a healthy nature

Natural Bulbs

Since the 1990s, we have been looking for a way to make bulb cultivation as natural as possible. At Natural Bulbs, we prefer to work with nature rather than against it. So we avoid pesticides and artificial fertilisers. 

By embracing organic growing principles, we managed to start a movement. We offer growers an economic perspective in converting to organic.


A natural soil is a home for billions of organisms that work together to provide good soil structure and increase resilience to pests. 

But of course, you have to give those hard workers in the soil a good chance to survive.


''Today we harvest better, stronger and healthier bulbs for our clients and we've measured life back into our soils''

Grower John Huiberts 


Robert Heemskerk took over the Natural Bulbs webshop in 2014 from Wilbrord Braakman, who was a true pioneer experimenting with growing organic bulbs back in the 1990s.


Robert discussed with new organic growers. Among others, he spoke to the Huiberts family. This family has been growing flower bulbs for more than 40 years. But in 2012, their soil had deteriorated to such an extent that the parents of three children had to make a drastic choice: 

Use even more chemicals or risk the switch to organic cultivation?

Happy bees

We give bees a responsible source of pollen and nectar due to organic bulbs and plants.


Everything you give attention to grows. 


 Very early in spring, bumblebees come out of hibernation. They fly out earlier than the bees, looking for the early spring flowers.


Thanks to Natural Bulbs to make bulb farming more sustainable, there is hope for brave growers who join in this transition.

Every year, 8.5 billion bulbs are grown in the Netherlands (crocuses, daffodils, lilies, gladioli, dahlias and especially a lot of tulips). Unfortunately, it has become normal to use artificial fertilisers and pesticides or plant protection products from the chemical industry in the process. This seems necessary to control pests and weeds. However, up to 114 kilos (lilies) of active pesticides and protectants per hectare are used in the process (compared with an average of 7.5 kilos for arable farming) (source: CBS 2022). Unfortunately, the result is a soil without life, i.e. without the resilience to actually prevent pests.
