Mark 11:14 states: "In response Jesus said to it." It is impossible to respond to or answer something, unless it first talks to you.
The fig tree spoke to Jesus, by saying "I will not give you any figs." The problem, or the mountain will talk to you and say: "I will not leave you. I am going to keep on giving you trouble." You must speak to the mountain - or the problem, and tell it to leave in the name of Jesus.
Jesus spoke to the fig tree. He did not pray about it, because He knew that He was operating in the Father’s will. The death of the tree started at the roots and not at the leaves. God starts to work at the root of the problem. Continue to believe God and thank Him for the answer that is on its way. God is expecting you to become mature in your praying and believing.
