At emergence, the Milo needs to be fertilized. This will be done by side-dressing the Milo with choice fertilizer, usually just Nitrogen. Fertilizing makes the Milo turn a pretty green and grow.
When the Milo starts to develop, it will look very similar to corn. I have been living on a farm my whole life and I still get the two plants confused for the first several weeks. However, my dad can tell you within a second with barely a glance which crop he is looking at. He looks at the spacing between each plant. Corn is spaced farther apart than Milo.
Above: The top plant is Corn. The bottom plant is Milo.
The plant grows quickly. Within two months, the plant is at full hight. These pictures show the hight progression:
There are many leaves on the Milo plant. These leaves feed the fruit.
A single seed-head will emerge from the leaves. Many seeds will form on the single seed-head. When the seed-head emerges, it is green in color.
In the next stage, the seed-head will turn an orangey-red. The time frame between these two stages varies based on the variety.
In the next stage, the seed-head will turn rusty-brown. This is the last stage before full maturity.
Above: In this picture, you can see the different stages of Milo. Some of the heads are green, some are orangey-red, and some are rusty-brown.
