Marcel Groeneveld

Remember when we visited our producer Marcel in December to see his production of Ilex?

This week we visited him again, but this time to discover his production of lilacs (Syringa vulgaris).

It was a pleasure to see the evolution of production through the months and the season.
Today we take you on a tour of Marcel Groeneveld’s house to discover his lilacs.

To start, we jump on the boat! (watch video)

90% of lilac is grown on the islands of the Westeinderplas in Aalsmeer.
The soil on these islands consists mainly of peat; which is optimal soil for the lilac.
Peat soil has a clod, so that the lilac bush does not dry out.

The varieties that are grown and they can be found in our offer are:

  • Dark Koster
  • Ruhm von Hortenstein
  • Lavelliensis
  • Maidens Blush

Cultivation takes two years; in the first year, the lilac is planted in the spring and the shrub is pruned in the winter.
In the following spring, around April, the bush will sprout.

Before autumn, approximately in August and September, the bushes are loosened from the ground and taken to the nursery by boat.
The shrubs are then placed outside the greenhouses.

The empty fields are covered with dredge in order to maintain the height of the fields.
Because of the cultivation, the fields drop by about five centimeters every two years.

In December, the lilacs outside the greenhouses are brought in in small batches.
The temperature in the greenhouse is brought to 36 degrees.
It takes about one week to open the flower.

During the loosening process, the leaf buds also open in addition to the opening of the flower.
These leaf buds are dissected and the flowers can be harvested two weeks later.

After harvesting, the flowers are prepared for auction.
The bare bushes are pruned and returned to the fields on the Westeinderplas.
