At what age is a coffee plant typically recognized as young, around four months into its growth?

In the context of coffee plant development, a coffee plant that is around four months into its growth would be classified as a young plant. At this stage, the plant has transitioned from its initial phase and is beginning to establish itself in its environment, but it has not yet reached full maturity, which takes several years.

A young plant exhibits growth characteristics that are distinct from seedlings, which are essentially the first stage of growth right after germination. The term "immature plant" may imply that it has not reached flowering or fruit-bearing capability, but the specific classification of "young plant" accurately reflects the typical recognition at this stage of development. Lastly, "mature plant" refers to a much older coffee plant that is capable of producing coffee cherries, which is not applicable at just four months of growth.

Thus, the term "young plant" accurately captures the essence of a coffee plant four months into its growth cycle, marking its development from a seedling towards maturity.
