Here is a picture of Wheat and a picture Tares (scientific name: loluim temulentum).
It is difficult to tell the difference between the two. In fact before wheat produces fruit, the tares look IDENTICAL to WHEAT.
In the spring, wheat and tares grow together but the tares grow faster and shoot their branches over the wheat, preventing the wheat from growing and ripening. Therefore, the tares appear taller, stronger and healthier then wheat. The tares actually overshadow wheat and take nutrients out of the soil causing the wheat to deepen their roots to find the nutrients they need. At this stage it is very hard to pull out the tares because their tendrils are wound around the wheat. if you pluck or uproot the tares prior to the wheat becoming mature than you run the risk of pulling up the roots and destroying the wheat.
The Parable of the Wheat and the Tares
24 "Another parable put he (Jesus) forth unto them, saying, The kingdom of heaven is likened unto a man which sowed good seed in his field: 25 But while men slept, his enemy came and sowed tares among the wheat, and went his way. 26 But when the blade was sprung up, and brought forth fruit, then appeared the tares also. 27 So the servants of the householder came and said unto him, Sir, didst not thou sow good seed in thy field? from whence then hath it tares? 28 He said unto them, An enemy hath done this. The servants said unto him, Wilt thou then that we go and gather them up? 29 But he said, Nay; lest while ye gather up the tares, ye root up also the wheat with them. 30 Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn." Matthew 13:24-30
Another point that is often neglected is that tares do not "magically" turn into wheat, nor wheat into tares. As much as one may resemble the other at any given time, in the end each reveals his true self.
Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them...
The work of separation must therefore wait until the harvest.
D&C 88: 81 Behold, I sent you out to testify and Warn the people, and it becometh EVERY man who hath been Warned to Warn his neighbor.
82 Therefore, they are left without excuse, and their sins are upon their own heads.
