In 1 liter of room temperature water, mix:

• ½ teaspoon of baking soda
• A very small pinch of sea salt (equivalent to a few grains, no more)

Stir until completely dissolved. The dilution should remain very light; this is not a concentrated fertilizer but a supportive treatment intended to aid the soil.

Once the solution is ready, use it no more than once a month, exclusively on well-established and healthy plants. Water the soil gently, avoiding contact with the leaves.

Observe the plant’s reaction over the following weeks before considering a repeat application.

Why This Method Can Benefit Certain Plants

When used sparingly, baking soda can help stabilize the substrate, while a tiny amount of sea salt provides minerals that are naturally present in the environment. Together, they can enhance the soil’s ability to retain water and promote more consistent root functioning.

However, not all plants respond the same way. Some appreciate these light additions, while others prefer unchanged soil. Observation is crucial.
