In the Spring, after coffee stops fruiting - it seems like it never stops fruiting though - I will prune the trees to about four feet of height to make it easier to cover next winter, and to renew the trees. They are supposed to be pruned of dead wood and old branches.
One thing I need to mention is that if there is hard frost coming, something like 28F, these quilt covers will not be sufficient. On cold hard freeze nights I use real comforters on my coffee trees.
Papaya is more tolerant.
Or maybe it is easier to get and grow.
But, for one thing, it is difficult to cover the whole papaya tree, as they usually are pretty tall, and secondly, they regenerate after frost damage rather easily. I normally, just wrap the trunk with the blanket and let the leaves to be damaged. Come spring, papaya will grow new leaves and branches.
Here is papaya tree that is probably four years old. It gets damaged every year, but then it grows new stems from the trunk (that was wrapped), and continues fruiting with abundance.
Keep warm tonight, and before we know, it will be Spring and new gardening adventures here in sunny Florida.
