Rootstocks User Guide

Rootstock selector for fruittrees  First of all rootstocks slow the vegetative growth (leaves, branches) of the fruit selections. Rootstocks take care of a sooner and richer harvest . Also they offer a better resistance against certain fungal deseases .

Customers choose rootstocks dependent on the general chosen race, the soil and stem height.

Step 1

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. This rootstock is suitable for less intensive crops and so very suitable for private usage .  M26 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
  • Plums usually are not grown on seedlings rootstocks . Seedling rootstocks produce large differences in vigor.  Plum cuttings are better.

Step 3

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 the customer 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.

  • 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
  • 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.
