Chazal (Beitzah 15:2) say “If one wants to ensure that his property will remain with him, he should plant an adar.”

The Bnei Yissaschar explains that he should implant into his heart the lessons of Adar, the emunah that Hashem dwells in this world, and everything is from Him.

This emunah will grant him success and wealth.
