Persimmon<br />
Persimmon plants are tra<strong>in</strong>ed to form a low head. They are headed back at a height<br />
<strong>of</strong> 60-70 cm from the ground at the time <strong>of</strong> plant<strong>in</strong>g to<br />
develop a framework <strong>of</strong> strong branches. In general, cultivars<br />
differ markedly <strong>in</strong> vigour and growth habit. Some cultivars are<br />
dwarf and highly precocious, whereas others are vigorous,<br />
upright and late matur<strong>in</strong>g. The dwarf and semi dwarf cultivars<br />
are tra<strong>in</strong>ed to a modified central leader system.<br />
•<br />
More vigorous, upright, narrow crotch angle types are<br />
tra<strong>in</strong>ed to a vase or palmette system. The prun<strong>in</strong>g is done<br />
dur<strong>in</strong>g w<strong>in</strong>ter season when trees are dormant, especially<br />
<strong>in</strong> January.<br />
Pecan nut<br />
Pecan nut plants are generally tra<strong>in</strong>ed <strong>in</strong> central leader system.<br />
The lowest branch is kept at a height <strong>of</strong> 1m from the ground<br />
level, while subsequent branches are spaced spirally at a distance <strong>of</strong><br />
Plant <strong>in</strong> flower<strong>in</strong>g<br />
stage<br />
30-35cm from one above the other. Once the<br />
framework is established, very little prun<strong>in</strong>g<br />
is done <strong>in</strong> mature trees. S<strong>in</strong>ce pecan nut<br />
is a term<strong>in</strong>al bearer, it requires only light to<br />
moderate prun<strong>in</strong>g. Heavy prun<strong>in</strong>g results <strong>in</strong><br />
extremely vigorous growth with no production,<br />
so only dried and broken branches are removed<br />
and overcrowded branches are th<strong>in</strong>ned.<br />
