I had given up on this lychee tree long ago. I was just too lazy to remove it after its apparent death from the freeze of mid-January. Miraculously, six months later, the roots began to send up sprouts again!
Fortunately, this lychee was propagated as an air layer, meaning that it is growing on its own roots. If it were grafted, the new sprouts would be from a rootstock of some variety that was undesirable for its fruit and the desirable fruiting variety grafted to the rootstock would be a goner.
There is also a mango tree on the finca that was killed to the ground, but began to re-sprout earlier in July. However, it is a grafted tree, so the variety that is now sprouting is the all too aptly named ‘Turpentine.’ I might be able to graft a good variety on to it next year, however.
As for the lychee, the killed parts represented years of growth. So we still have a very big setback from the freeze. But the will to live is stronger than the freeze.
