On average, the TerraCottem treated trees have a 2 week longer vegetation period compared to both the mycchorizae treatment and the control;

"Blütenbildung" = bud development:

more buds on the Magnolia Kobus variety;

"Stammzuwachs" = stem growth:

both TerraCottem and mycchorizae Mykorrhiza have a positive effect on the stem growth;
