A person who goes outdoors during the month of Nissan and sees trees blossoming can recite a blessing for the fruit trees. The blessing can be said alone or with a minyan, and can be said within a city or outside of it. Women are also obliged to say the blessing. The blessing is said on fruit trees and not on other trees. It is best to recite the blessing during the month of Nissan, but it can be said in the month of Iyar if necessary. If someone cannot find two trees, they can find rabbinic sources that allow the blessing to be said over one tree. The article also provides information on other customs and practices during Pesach and the counting of the Omer.
