Requirements for growth

A healthy plant is usually upright with green leaves. Plants need air, light, warmth, water and nutrients to be healthy.

If a plant doesn’t have one of these requirements it could affect its growth or even die.

For example, a plant that is kept in a dark place will grow tall and spindly in search of light and then become weak and die.

A plant that is not watered will have a weak stem and dried-up leaves and will eventually die.

A seed will not produce a plant at all if it is kept too cold. The seed needs warmth to germinate (develop from a seed into a plant) and start to grow into a healthy plant.
