An M9 stoolbed glowing in spring sunshine

Caledon Valley Nursery has M7, M9, MM109 rootstocks and a range of Cornell Geneva rootstocks (currently 222, 969, 778 and 890) in stoolbeds in the motherblock.

Harvesting the rootstocks
The nursery makes finished trees in the production nursery on all these rootstocks from the motherblock, as well as on tissue culture rootstocks. The nursery also has budwood blocks and expansion of these as well as further rootstock stoolbeds are planned.

A speciality of the nursery is to make trees on MM109/M9 interstocks, with success being experienced by growers on these.

The nursery uses its best efforts to assist growers as they plan their tree planting needs, years in advance. An assessment is made of what future stock will be available and growers are able to place formal orders accordingly.

Rootstocks are harvested from the stoolbeds in the motherblock and planted out in the production nursery in winter.

At appropriate times in the course of their two year lifecycle in the production nursery the rootstocks are budded with the varieties chosen by customers who have placed formal orders. A contingency buffer of rootstocks is also budded with the same variety, to ensure that quality trees of good height and caliper are available for these formal orders.

Collection of data at each stage in the life of the plant in the motherblock and in the production nursery is an important process and there is a quality and stock control team dedicated to this, all year round.

The finished trees are graded prior and after harvest and tree size is communicated to customers. After trees have hardened off, in winter, they are lifted, tagged and heeled in according to grade, in moist sawdust, prior to despatch.

Heeling in the harvested trees

Tree despatch takes place from the middle of July to the end of August, with trees transported overnight in insulated trucks. For those trees destined for the Western Cape, Caledon Valley Nursery has teams that receive the trees, oversee the offloading process, count each order a final time and attend to the documentation.

Caledon Valley Nursery is also very willing to help customers who have varieties that they wish to test for potential future commercial potential. The nursery takes scion material from these customers and makes finished trees so that the customer can bring these into production in trial orchards.
