Rootstock selector for fruittrees
Rootstocks slow the vegetative growth (leaves, branches) of the fruit selections and take care of a sooner and richer harvest . Also they offer a better resistance against certain fungal deseases .
Dependent on the general chosen race , the soil and stem height a rootstock is selected .
Choice of the tree shape and stem height required.

Some additional information and things to know regarding your rootstocks .
- B9 is a Russian rootstock alternative : more dry resistant/lower temperatures resistant.
- M26 does not like wet soil. It is suitable for less intensive crops and so very suitable for private usage . It requires less care and pruning, support and watering. The wind resistance makes it suitable for,single stem shape
- M9 is most commonly used in commercial orchard
- Quince MC is mainly used for commercial use because of weaker growth. This makes it suitable for espaliered trees . Quince MC is more frost sensitive.
- Quince Adams is in terms of vigor amidst Kwee Kwee MA and MC
- For plums usually but not always no seedlings rootstocks are used . This is due to large differences in vigor
Tune to conditions.
The above table is a directive. Is a fast-growing breed used in a fertile soil, the growth (yet) should continue to be held back by a weaker rootstock. If one wants a friendly maintenance tree and later fruiting , no problem, it can be reached by using faster growing rootstocks. The table below provides help in the alignment of the selected strain.
- SLOW / WEAK GROWING ROOTSTOCKS
- For shorter stems
- For more rich soil types
- For powerfull grafts/ races
- For short life cycle
- More maintenance
- Crop allready after 2 yr
- Easy to prune
- Stake nessessarry
- Shorter plant distance
- Fast / STRONG / POWERFULL ROOTSTOKS
- For taller stems
- For more poor soil types
- For weaker grafts / races
- For longer life cycle
- Low maintenance
- Crop after 7 jaar
- More difficult to prune
- Stake only short while after planting
- Wider plant distance
Since fruit like apples and pears have fairly shallow roots it should be considered to check soil at 0 to 50 cm depth
Stems in between rootstock and variety.
Sometimes between the rootstock and the variety, species or cultivar a stem in between is used.. With apples this is primarily done to create a beautiful, straight trunk for half-standard and tall trees. With pear a strain in between is sometimes necessary because of incompatibility of the chosen variety.
