For best results, please consult the flowering types as well as the Recommended Pollinators section on each product page. Interested in learning more about pecan trees? Find pollination and other helpful information at the Northern Pecans blog from U. Pecan Tree Pollination in a Nutshell.
Flowering Types in Pecan Trees Some pecan trees shed pollen first and their pistillate flowers are receptive of pollen later in the season. You asked, and we delivered. Our Supreme XL Potted fruit trees are our biggest and most robust potted trees ever. Place a screen or other protective barrier over the drying nuts, or you're likely to attract every squirrel in the area. Shelled pecans store well for up to one year at 32 degrees Fahrenheit, and in-shell pecans can handle storage temperatures between 32 and 45 degrees Fahrenheit.

Broadcast the fertilizers on the surface in a circle twice the width of the canopy. Most pecan varieties shed pollen either too early or too late to pollinate the female flower of the same tree. Multiple varieties in the same area can improve pollination. Photo by Trevor Hylton. Lack of water, especially in the dry hot summer, can reduce yields and nut quality and lessen the prospects for production in the ensuing year.
On poorly drained soil, waterlogging can cause similar outcomes. A single isolated tree will not produce very well because it will not be effectively pollinated. Most varieties shed pollen either too early or too late to pollinate the female flower of the same tree. Having different varieties within a couple hundred yards increase the probability for good pollination.
Rainy weather in early spring can wash off pollen and restrict the movement of pollen by wind. Overcrowding due to over grown trees or too close spacing will eventually lessen production. Self-pollination leads to poor nut growth and development, resulting in low quality kernels and increased nut abortion.
Therefore, it is imperative that you consult a pecan variety pollination chart learn more at www. It is recommended to find at least two to three varieties that shed pollen at the same time the main variety is receptive. Research indicates that effective pollination may decrease at distances greater than feet from a pollen source, so you must have pollinator trees no further than every fourth row. The duration of pollen dehiscence shedding for a cultivar may vary greatly in different years, as a function of variable weather and due to location of the orchards.
Sustained high winds coupled with low humidity tend to shorten the period of effective pollination, both by accelerating pollen dehiscence and by shortening the period of nutlet receptivity. High humidity delays pollen dehiscence and extends the period of nutlet receptivity, according to research published in proceedings of the National Pecan Association in Small orchards may not need pollinator treesif native or seedling trees are within a few hundred feet of the new planting; however, large commercial plantings should include pollinatorswithin the orchard.
Figure 2. When planning an orchard, both Type I and Type II varieties need to be included to ensure pollination of all varieties. However, it is not as simple as planting a random combination of protandrous and protogynous pecan varieties. Figure 3.
