A. May one harvest his field during Shemitah for purposes of distribution?
One may not harvest his field in the normal method. He is to harvest only small areas at a time, and preferably use his hands. One is not to cut the fruits off the trees using a regular fruit cutting scissor and is rather to use a knife.
How much produce may one take at a time for his personal use?
Some Poskim rule that the amount that is permitted to be taken from the field is the amount of food needed for a few days worth. Others however say one may only take three meal’s worth of produce.
B. May one cut branches off a tree for the purpose of using them?
Yes. However he must intend not to benefit the tree in the process.
May one cut Sechach during Shemitah to use for his Sukkah?
Yes. However it is best to do so in an irregular method than that used for trimming trees.
May one cut branches of a fruit tree?
One may only do so if the tree has grown its fruit at least 1/3 of their growth, or if the tree has not yet begun to produce any fruit.
Does Sechach have Kedushas Sheviis?
