I love decorating and covering the sukkah with plants grown on site.
After the ingathering from your threshing floor and your vat, you shall hold the Fest of Booths [Sukkot] for seven days. You shall rejoice in your festival… for the Lord your God will bless all your crops and your undertakings, and you shall have nothing but joy (Deuteronomy 16:13-15).
Chag sameach!
