For quite some growers in that do a summer planting for Long Day varieties, the new planting season has started.
Our experience in the last day is that planting depth can be quite important. Especially if a variety is sensitive to crown diseases, the difference between good planting, just good, or too deep is quite a lot.
Last year i have seen strawberrie plantings in greenhouses with till about 20% of the plants dying because they where planted to deep and another 20-30% of the plants not growing fine because of incorrect planting.
Standard rule is: the top of the tray should be about 2 cm above the substrate level. In that case the head of the plant dries up way bether, causing healthier plants (less crownrot for example).
Below a picture – this seems to deep but is very good planting work.
On the picture the plants seem a bit high, is between 2-3 cm ü very good. With correct irrigation this gives the perfect start fo the plants: 7 days after planting the first roots are allready around 12-15 cm long. That is way longer as the standard 1 cm/day growth would give.
