• When one sees blossoming fruit trees for the first time during the month of Nissan , one should say this blessing:
Transliteration: Boruch A-toh Ado-noi E-lo-hei-nu Me-lech Ho-olom She-lo Chi-seir Be-o-lo-mo Ke-lum U-va-rah Vo Be-ri-yos To-vos Ve-i-lo-nos To-vos Le-ha-nos ba-hem Be-nei A-dam.
Translation: Blessed are You, L-rd our G-d, King of the universe, Who has made nothing lacking in His world and created in it goodly creatures and goodly trees to give mankind pleasure.
• This blessing is said just once a year - the first time that he sees it1.
• Although the ideal situation is for the blessing to be said during the month of Nissan, it would seem that ipso facto ("Bidieved") if one did not see the trees blossoming until the month of Iyar, it would be permitted to say the blessing2.
• One is permitted to say this blessing even on the Shabbat and on holidays3. Preferably, an effort should be made that the blessing be said when seeing two trees at one time, however, if there is only one tree the blessing can still be said4.
• The blessing should not be said on trees which grow fruits that are grafted from two species, such as nectarines5.
• In Australia and other countries of the southern hemishphere, where the trees blossom during the months of Elul and Tishrei, the blessing can be said at that time6.
