In your Halachos on Birkas HaIlanos, you mention that one shouldn’t use trees that are Orlah. I planted two fruit saplings a year ago (when they were blooming). I don’t know how old the saplings were at the time I bought them (and they couldn’t tell me). Is it mutar to say the bracho on these trees this year when they bloom?
Saplings that were replanted have a din of Orlah as if they were planted anew – in other words, the three years of Orlah begins from the time that they were replanted (Shulchan Aruch Yoreh De’ah 294:16).
If a tree was uprooted but had earth attached to the roots that was sufficient for the tree to live off, and was subsequently replanted, one need not restart the count of three years of Orlah (ibid, 294:19 – see also Pischei Teshuvah 294:13)
