WHEAT

If you grew winter wheat, in late spring the heads will bulk up and turn beautiful, then the plant will start to turn brown. ... You can start harvesting as soon as the wheat seeds pass the milk stage, although the grains will need to dry up and harden a bit before they're ready to eat.

Turning from green to brown is one excellent way of judging the development of the wheat. Then you need to watch the head. Straight up and down means that it's not there yet. When it bends over to better release it's seeds you know it's very close. 

Place a kernel of wheat in your mouth and bite down, it should crunch. It should not be soft or chewy. If it's chewy, leave it awhile longer to dry down. 3) Nodding – Seed heads will start to nod or bow on the stem when they are ready to harvest.

Tares will inevitably grow up and around the wheat.  It is best to leave the Wheat and once the  is ready to harvest then the tares are easy to spot and pluck out because they will not BEND.  They stand proud and tall.  This makes it easy to remove. 

The final test is to check the moisture content of the seed.

Harvest: Harvesting of spring wheat occurs from mid-August to mid-September. Planting: Planting of winter wheat occurs from mid-September through October. Harvest: Harvesting of winter wheat occurs from mid-May through June.

Four months separate the sowing and the harvesting. Barley harvest could begin around April 15. Wheat harvesting begins six weeks later in late May or early June. In May the fields would be white unto harvest.

Matthew 13:24-30

Weeds among Wheat

Yeshua presented another parable to them, saying, “The kingdom of heaven is like a man who sowed good seed in his field. 25But while his men were sleeping, his enemy came and sowed  weeds among the wheat, and left. 26And when the wheat sprouted and produced grain, then the weeds also became evident. 27And the slaves of the landowner came and said to him, ‘Sir, did you not sow good seed in your field?  How then does it have weeds?’ 28And he said to them,  'An enemy has done this!’ The slaves *said to him, ‘Do you want us, then, to go and gather them up?’ 29But he *said, ‘No; while you are gathering up the weeds, you may uproot the wheat with them. 30Allow both to grow together until the harvest; and at the time of the harvest I will say to the reapers, “First gather up the weeds and bind them in bundles to burn them; but gather the wheat into my barn.”’”

Matthew 13:36-43

The Weeds Explained

36Then He left the crowds and went into the house. And His disciples came to Him and said, “Explain to us the parable of the [v]weeds of the field.” 37And He said, “The one who sows the good seed is the Son of Man, 38and the field is the world; and as for the good seed, these are the sons of the kingdom; and the weeds are the sons of the evil one; 39and the enemy who sowed them is the devil, and the harvest is the [w]end of the age; and the reapers are angels. 40So just as the weeds are gathered upand burned with fire, so shall it be at the [x]end of the age. 41The Son of Man will send forth His angels, and they will gather out of His kingdom [y]all stumbling blocks, and those who commit lawlessness, 42and they will throw them into the furnace of fire; in that place there will be weeping and gnashing of teeth. 43Then THE RIGHTEOUS WILL SHINE FORTH LIKE THE SUN in the kingdom of their Father. The one who has ears, [z]let him hear.
