Family business since 1960

Aardbei Extra

Aardbei Extra is the family business from Robert and Liesbeth van de Zanden with over 50 years of experience in the cultivating strawberries and strawberry plants. In the sixties we started with growing various vegetable crops including strawberries, which now is our core business.

Quite quickly we noticed that a successful strawberry cultivation is mostly depended on the quality of the plants. With this insight we decided to focus our business on the propagation of strawberry plants. Currently we see that a lot of growers are looking for varieties which are more productive, less sensitive to diseases and which can decrease the picking costs.

More than ever, we nowadays are brainstorming with our clients about varieties, plant types and doing research on flower buds. Also we more and more have conversations with breeding companies and sales organizations.

It is our biggest challenge to find the right varieties in our assortment and to optimize our cultivation systems to the needs of our customers.

To test the quality of our plants, we created a trial and test field.

A year at Aardbei Extra


Preparations and planning

In January we do the planning for our new season. Our tractors and machines are getting maintenance and now it is time to take soil samples of our fields.

We also deliver the first batches of strawberry plants to our customers who want to be early on the market with their strawberries.


Soil cultivation

In February we focus on bringing our fields into top condition.

Our plots are being prepared for planting, like spreading compost, fertilizing and plowing the fields.


Planting of the motherplants 

The mother plants are being planted with GPS controlled machines and afterwards covered with foil to protect them against frost, and to achieve earliness.

Early this month we plant mother plants partly in troughs for tip production on our unique table-system.


Caretaking of the crops

The first flowers are being removed from the mother plants to trigger the development of runners.

The mother plants on the table tops are being taken care of.

Green manures like Marigolds and Oats are sowed and the sprinkling systems are being installed.


The crops will be weeded

In the field we remove the foils which have protected the plants over the last few months. The crops will be weeded and the soil between the rows of mother plants cultivated.

The young runners will be spread by hand with the help of our 26 metres wide “flyer”.


Caretaking of the crops

In June our main focus is to take care of the crops. There are weekly checks on the fields for diseases and pests. Irrigating and taking out the last weeds by hand.

Leaf samples are taken on a regular base, depending on these analyze results, growth is adjusted.


Focus on stek plants

The accommodations for the seasonal employees are being prepared.

Our plants receive a final inspection from the Nak Horticulture inspection authority.

In July, the focus is mainly on harvesting, counting, packing and dispatch of our stek plants.

Which find their way to growers who make their own tray plants.



Harvesting, sorting and transplanting

The fresh bare-rooted strawberry plants are lifted early morning around sunset, and be moved quickly to our coldstores where they are stored under perfect condition to keep their moist and vigor.

In the sorting hall, on the carousel, the fresh plants are graded and packed.

During the day, in the field, fresh plants are transplanted on a waiting bed.


The big cleaning

After a busy season, the entire company, the accommodations, the tractors, machines and fleet are thoroughly cleaned.

All the packaging of our customers will be returned to our farm. By steaming we disinfect the crates again.

The office is also running at full speed.


Taking care of our crops

Crop care takes place on the fields with frigo and waiting bed plants.

We also welcome customers to visit our plant fields. This is an important point of contact with our relations where we demonstrate the quality of our product.

And… have time for a cup of coffee.





Preparation for harvesting

The first preparations are made for harvesting of the strawberry plants, which are dormant by the end of November.

In addition, we are preparing the accommodations again for our seasonal employees.


Harvesting of the strawberry plants

The strawberry plants are harvested, graded, counted and packed.
