Climate Required for Pecan-Nut Production
The pecan-nut tree is indigenous to the central southern states of the USA and is well adapted to many areas in South Africa that have a subtropical climate. The tree is also well adapted to large areas of South Africa with short, cold winters and long very hot summers. Low temperatures and even frost in June to August are required for successful budding and flower formation. During the summer months (October to April), the tree requires high temperatures for fruit growth. Trees are successfully established in valleys and along rivers where the winter temperatures are low and frost occurs. J.H. Oosthuizen and A.J. Joubert
Citrus and Subtropical Fruit Research Institute, Nelspruit Soil Requirement for Pecan-Nut Trees
The pecan-nut tree performs best in a fertile, well-drained, deep soil with a loose to medium texture.
Under favourable conditions and in suitable soil, the tree roots will spread in a large volume of soil. It has been established that the volume of root distribution of the mature tree is twice that of the branches. Roots penetrate deeper that 3m into a loose, porous soil. T.J Koen
Citrus and Subtropical Fruit Research Institute, Nelspruit Soil Preparation A pecan-nut planting is a long-term investment, which requires a high initial capital outlay. It is therefore imperative to plan a new planting thoroughly and well in advance. It is important to examine the soil for suitability regarding depth, drainage and compacted layers. The physical suitability of a soil can only be evaluated by digging holes in the ground and examining the soil profile. If the physical properties of the soil are suitable for growing pecans, it is vitally important to prepare the soil carefully and well in advance of planting.
