Pecan Nut trees are a large hardy deciduous tree growing to approx 30m depending on variety and conditions. 70-180mm lateral shoot length is best for nut production. Variety selection and design of the orchard to ensure cross pollination is vital. Without canopy management yields will fall due to reduced photosynthesis and limb death occurs reducing yields and potentially allowing the incursion of pests and diseases. Leaf damage (reduce photosynthetic potential). If you love to garden and love to bake up some pecan pies on the weekend, growing a pecan tree might be the next project for you.

References University of Arkansas System Research and Extension: Pecan Trees Managing Light Levels in the Pecan Orchard. Growing pecan trees have a long taproot that is susceptible to disease if the soil is soggy. Southern pecan trees require a long growing season, making short-season varieties most suitable for Virginia landscapes. Pecan trees (Carya illinoinensis) grow wild across a wide swath of the central and southern United States, from northern Illinois south to the Gulf Coast and from southwestern Ohio west to Texas’ Edwards Plateau. Varieties are classified as protandrous (Type 1) – the male flowers (catkins) produce pollen first – or protogynous (Type 2) – the female flowers are receptive first. Mexico, Peru, Brazil, Israel, South Africa and Australia all grow them commercially. It is recommended that soil and/or foliage tests are undertaken to determine the nutritional requirements in your orchard. The largest member of the hickory family, pecan trees often grow to a height of over 70 feet with a spread of greater than 80 feet. Grafting is a process where you take a cutting from a cultivar pecan tree and allow it to grow on the rootstock tree, essentially blending two trees into one. Similar climatic and environmental conditions can be found in Australia that are suitable for pecan growing, however Australia has one key advantage over America in that the Australian pecan industry is largely disease free. Grass competition is one of the major problems facing young pecan trees. Trees should be kept approximately as high as the distance between rows to avoid lower limb shading producing limb death and infestation points for borers and longicorn beetles. Pecans are monoecious – meaning they have male and female flowers which open and mature separately. Pecan trees now find themselves growing many thousands of miles from their native North American forests. Pecans are tolerant of high temperatures in summer and require more than 2000 heat units to produce good quality nuts. If you would like additional information on growing pecans, please contact the APA at E: info@pecangrowers.org.au. North Florida is a good environment to grow pecans.

Their production is expected to increase as Asia’s consumption of pecans rises. Most pecan varieties require 200-220 frost free days to mature nut crops, late spring frosts or early autumn frosts can affect yield. They are difficult to transplant and need special attention throughout their lives but what a payoff they return! Pecan trees like long, hot summers and moderately cool winters along with deep, fertile, well-drained soils. Pruning in later years is necessary to ensure sufficient light reaches inside the canopy of the tree and the orchard floor. Pruning encourages both upward and lateral growth to make the most of sunshine and make for easier tree management. Deep well-draining alluvial soils are considered to provide the best growing condition for trees, with at least 2 metres of soil depth. They thrive in warmer areas and are most often grown commercially in the deep south in Texas and Louisiana. Texas, New Mexico, and Georgia together account for almost 80% of the global production of pecans. Although the tap roots may reach 7 metres, most of the tree’s feeder roots occur within the top metre of the soil. Pecan trees grow best in sunny areas with good air movement and deep, porous soil. Training young pecan trees to a central leader system is essential to provide a strong structure for future production. Dry conditions in spring and early summer are critical for effective pollination and early nut development. Growing Pecans Trees in South Central Pennsylvania. Pecan trees don't require a lot of care once planted, but they do need a lot of space. Prune to a flat topped triangular hedge to give more light on the canopy and hence more yield.

They can be grown from USDA hardiness zonesapproximately 5 to 9, and grow best where summ… Pecan Plant Physiology, Climate and Soils. Although pecan trees can be grown further west, nut production may be inconsistent. The central leader system reduces splitting and breakage in later years, which impacts yields, and begins the process of managing light levels throughout the tree and orchard.

It is therefore essential that adequate water and nutrition are provided in this soil zone. Sunlight is required to produce food for the tree. Pecans can be grown on heavier soils with higher clay content than alluvial soils but growth may be restricted and care with irrigation to avoid water logging is critical. Forkert. Taller trees than this do not necessarily produce more nuts because lower limb shading reduces production from the lower tree. These shoots shade out but don’t give nuts for 2-3 years. Pecans are native to about 150 counties in Texas, but are capable of growing and producing in every Texas county. Varieties differ in their climatic suitability, yield, kernel quality, propensity for alternate-bearing, susceptibility to insect and fungal attack and to some extent in ability to withstand water deficit.

For many, growing pecan trees is quite the hobby, for not only do they produce a delicious snack, but their large size makes them excellent shade trees. In an interview with Farmer’s Weekly in January 2011, Philip Antrobus, pecan nut farmer and then chairperson of the SA Pecan Nut Producers’ Association (SAPPA), said that pecan nut production was a lucrative industry. It is probably best not to use these groups when there is a lot of scab disease already present on the trees, because higher pathogen populations increase the odds for resistance selection. Most of the remaining 20 percent come from six other countries with warm summers and extended growing seasons.
