“ Which do not grow from the earth: All things ultimately come from and return to the earth in some fashion. The sages refer, thus, that things which do not directly come from the land, such as processed foods, meat, fish, etc.
For everything: This refers to the all-inclusive blessing שהכל נהיה בדברו‎ "For everything exists by God's word" discussed in the previous mishnah.
Unripe fruits: That is, fruits which have not yet ripened and have either fallen early or been picked early. Unripe fruits have a lesser status than ripe fruits and thus have a different blessing. ”
