Sometimes, and without knowing why, our house can acquire an unpleasant smell or, more simply, it can have no smell at all. It is a reality that has a very simple solution: plant a lemon in a cup.

Lemon is one of the most widely used and appreciated fruits. This citrus fruit is rich in vitamins C, P and group B, has disinfectant properties capable of eliminating bacteria and fungi and is used in the production of flavourings and cosmetic products.

Below we explain how to plant a lemon in a cup step by step, to have an excellent result in the shortest possible time.

To start you need the seeds of about 5-10 lemons. The seeds should be whole and in good condition, and placed in a glass of clean water to hydrate.

Discard any remaining seeds, drain them after a few minutes and dry them with paper towels. Pour some damp potting soil into the cup, then arrange the seeds in a circular pattern that covers all of the potting soil.

Cover with a small layer of gravel and wait about 10-15 days, after which the seedlings should appear. From now on, water every morning with a small bottle equipped with a spray diffuser.

If the seedlings are too close together, you can repot them or remove one. Their growth is slow, and it will take about 4 or 5 months to reach a size that requires transplanting.
