THE TECHNICAL NOTE - How to properly protect your nursery 🌱

The nursery is a space dedicated to seedlings and young shoots. They develop in optimal conditions before being transplanted to their final place in the field.

How to protect it:

– Weed the nursery and properly disinfect your tools to avoid contamination

– Eliminate the plants showing symptoms of disease, to avoid dissemination

– Preventive phytosanitary treatment with nematicide/insecticide: it can be applied according to the history of the production site which must be well known by the producer

– Curative phytosanitary treatment: following the identification of the disease or pest, apply the appropriate treatment. In case of disease on a part of the nursery only, treat it last to avoid contaminating the rest of the nursery.

– The association with other plants can be interesting (e.g. marigolds can help to fight against nematodes).

– The use of anti-insect nets will prevent the arrival of pests that can attack the nursery or be a vector of viruses.

Agroecology: some tips

Are you familiar with soil mulching?

It is a method of covering the soil to limit the germination of weeds or to slow down their development.

The benefits of mulching:

– Fight against soil erosion by wind and rain

– Increase soil fertility

– Increase biodiversity around the plant

– Choke off weeds

– Create a micro-climate by regulating the temperature

– Keep humidity and avoid evaporation

Cabbage, which density?

Once your cabbage plants in the nursery are at the right stage (4 to 6 leaves) you have to go to the transplanting stage!

Cabbage is a species that requires a fairly large spacing of 40 to 60 cm between rows and 40 to 50 cm between plants.

This planting density represents about 35,000 to 55,000 plants per ha and depends on the spacing and the type of plot chosen (hollow bed, raised bed, ridge etc.).

Cabbage is a plant that needs space to develop well and give the biggest apples possible!

Some varieties such as F1 CALIF have a less spread out growth habit and allow cabbage to be planted at a slightly higher density.

Tomato: tomato moth


It is a moth that, in its caterpillar stage, eats the inside of the fruit, the leaves and the flowers. It also causes rotting that makes the fruit unpalatable.


– A large hole on the fruit is characteristic of an attack. Simply open the fruit to observe the caterpillar inside.


– Use pheromone traps to monitor for the first appearances of the moth

– Eliminate the attacked fruits

– Do a superficial plowing after the last harvest
