How Does Bird Seed Get Planted?

While birds are feeding, at bird feeders hanging at various homes and businesses, some seeds spill onto the ground. Other seeds consumed by birds are not digested. These seeds land onto the ground wherever the bird happens to be when it defecates. When squirrels raid bird feeders, they spill more seeds. The squirrels also steal seeds and plant them into the ground for feeding during winter months. Those families with pet birds must periodically clean their cages. They may inadvertently plant seeds if they compost or throw the loose seeds out from the bottom of the cages into the yards or gardens.

What Grows From Bird Seed?

The type of bird seed that individuals are placing into their bird feeders controls the type of plants that will grow from bird seed. For example, if you are feeding finches Thistle seed, then the plants that grow under your bird feeder will be Thistles. These are weeds that farmers do not want growing in their fields. However, if you are feeding a mixed bird seed containing Millet and Milo, then something that looks like grass will grow. Millet grows into a pale green shiny plant used in cereals and bird seed that looks like grass. Milo also grows into a plant that looks like a grass, but is actually a type of sorghum grown specifically for its grain. It grows quickly and resists drought, explaining why it springs up so fast under bird feeders.

Throw Out Moldy or Growing Seed

Store your bird seed in a cool place in an airtight container where it will stay dry if you buy it in bulk. If you notice mould growing on your bird seed, throw it away. The mould may contain toxins that are harmful to birds. If the seeds are growing in your container, then moisture has got to your bird seed. Any moisture may indicate the presence of mould. Therefore, you should dispose of it.
