- Once a year when you see fruit trees blossoming, say the nusach brought in Shulchan Aruch. It does not have to be said specifically in the month of Nissan. (ShA – MB1,2)
- When is the last time that you can say this beracha? If you have not yet seen any blossoming trees this season, you can say the beracha until the fruit is fully ready. If you have seen the trees already you can only say the beracha before the fruit develops. (ShA – MB4,5)
