Pecan Trees from Seed

With our last post we showed some older pictures from planting pecan seed in April. Now that we  are  almost in July, they are starting to emerge.   I think its a good idea to become familiar with how a pecan seed germinates and grows in its natural environment. At left is a photo of a germinated pecan. To germinate, the seed must first imbibe enough water to swell the kernel and crack open the shell.  As the seed starts to grow, a vigorous tap root is the first structure formed. Shortly thereafter, a smaller, wiry shoot develops and grows upwards, poking through the soil surface.In nature, a new pecan seedling will invest most of it energy in growing a massive, deep tap root. Above ground, first-year pecan trees rarely grow more than  8-12 inches in height and produce only a hand full of  leaves. This growth pattern is the tree’s way of ensuring seedling survival. Between fires, floods, grazing animals and brush hogging, seedling pecan trees often lose above ground parts. By storing a massive amount of plant energy in the tap root, a pecan tree can easily replace a lost top with a new sprout.
