A lulav that was stolen or dried out is pussel. A lulav from an ashera tree or from Ir Hanidachas is pussel. If the top was cut off or the leaves fell off it is pussel. If the leaves are spread out it is kosher. Reb Yehuda says that you should tie it on top. Tzeni har habarzel is kosher. A lulav must have three hand breaths to wave and one hand breath on the bottom.

Succa 3:2

A hadas that was stolen or dried out is posul. If it came form an asheira tree or from ir hanidachas it is pasul. If its head is cut off, if it’s leaves were cut off or if more berries then leaves it is pasul. If you took off the berries it is kosher but it can’t be done on Yom Tov.
