Description

• Gardeners have been growing Mahan pecan cultivars since the early 1900s. The trees reach 70 to 150 feet in height. Mahan produces its first crop of nuts at least six years after planting, although some trees require a few more years beyond that to produce a substantial crop.
  
  

Flowers

• The Mahan cultivar produces both female and male flowers. The male flowers, resembling greenish-yellow catkins, produce pollen in mid- to late season. But the female flowers are receptive in early to mid-season before the male flowers' pollen is available.
  
  

Pollination

• Using another cultivar that produces and accepts pollen at a different time ensures the Mahan cultivar gets pollinated. Favorable weather and a light wind takes care of pollination between the two trees. Pecan trees can cross-pollinate with another pecan tree up to a quarter mile away.
