When the foliage in your garden begins to thin, it is a good time to check out the places where some plants have not done as well as others and smell the soil. Everyone who gardens knows that soil is alive and the well-being of your plants depends on the nutrients in your soil. When the children were little I took them to the river, the creek, the fields, and the woods to feel and smell the differences in the soil. Healthy soil has a rich distinctive aroma; soil devoid of nutrients looses this all-telling “dirt smell” and will need some help to regain any strength.
The texture of dirt depends upon the mineral content in it. Sand has the largest particles that can be seen, silts are very small and clays are microscopic. To acquaint yourself with the smell of healthy soil, go to a spot in your garden under a tree, dig a trowel full and inhale the aroma....it will smell alive. It has gathered nutrients from the leaves which have fallen and the grass clippings which have been thrown its way. The decomposition which has ensued over time has created a rich, nurturing soil full of nutrients, which is why the forest floor is always occupied.
Since no amount of processed fertilizer can add to the garden what decomposing vegetation can add, remember to toss grass clippings and fallen leaves into the flower beds. Over the winter with rains and snow, they will meld into the garden, disintegrate, and replenish the soil while you are not noticing.... the garden will thank you.
