How long to plants usually grow in soil?

There's no single answer to how long plants grow in soil because it depends on many factors:

* Plant species: Some plants grow incredibly fast (like beans), while others take years to mature (like oak trees).

* Growing conditions: Sunlight, water, temperature, and soil quality all play a huge role.

* Plant stage: Are you talking about the time it takes to germinate from a seed, the time to grow to full size, or the entire lifespan of the plant?

Here are some general timelines for different stages of plant growth:

* Germination: From seed to sprout, this can take anywhere from a few days (for fast-growing plants) to several weeks (for slower plants).

* Growth to maturity: This can range from a few weeks (for annual herbs) to decades (for trees).

* Lifespan: This can be a single season (for annuals) or hundreds of years (for some trees).

Do you have a specific plant in mind? If you tell me the type of plant, I can give you a more accurate estimate of how long it might take to grow.
