Wheat Seeds

Seeds are an item used in farming. They can be found by destroying Tall Grass to or by harvesting fully-grown wheat. The chance of finding seeds while tilling is fairly small compared to harvesting wheat, which yields from 0 to 3 seeds per tile harvested (about 1.6 seeds/tile harvested in average). Seeds can be placed in farmland by right-clicking, where they will grow.

As of Beta 1.6, seeds will only drop from Tall Grass.

Growth & Growing Conditions
When left alone, seeds planted in farmland will grow to become wheat which can be harvested. Planted seeds need at least 1 block of air above them to grow, and grow more quickly when planted near abundant water and sufficient light. The image below shows the stages of growth from newly planted seeds to wheat that is ready for harvesting. Bone Meal can be used on the planted seeds to instantly mature the plants to the last stage of growth.



Seeds must be grown in an area surrounded by some sort of barrier or your crops are at risk of being trampled. After stepping on tilled dirt with or without seeds, the dirt will revert back to normal after only a few steps (although this is randomly controlled because tests have shown it ranges anywhere from 1 steps to 10). Passive and hostile mobs can both affect these crops (apart from spiders and wolves, as of Beta 1.4). If trampled, planted seeds do not drop seed items, instead being permanently destroyed.

As of Beta 1.3, crops may not be planted within four blocks radius of redstone ore

Harvesting
When fully grown, the crops will drop 1-2 wheat as well as 0-4 seeds. Allegedly, as of Beta 1.2_02, when harvesting fully matured wheat, there's a chance of it not dropping wheat. Additionally, at stages 5 and 6, seeds may be dropped if the crop is destroyed, although wheat won't.

Finding
As of Beta 1.6, Seeds can not be tilled from grass. They can be found by destroying Tall Grass, or by harvesting Wheat.

Till Grass will make farmland like dirt.
