Do Eggshells Provide Plant Nutrients?
Eggshells contain calcium, which is a key nutrient for many plants.
That doesnt mean you should just crumble eggshells and toss them into your monsteras pot.
Garden plants like tomatoes and citrus trees benefit from additional calcium to strengthen their blossoms and fruit.
Most houseplants dont usually need extra calcium.
They get enough calcium and other nutrients from an all-purpose potting mix.
Its not beneficial for anyone to be putting eggshells in their potted plants, adds Lalicata.
Dont crumble them by hand.
Grinding the shells into a fine powder helps the calcium get into the soil and the plant faster.
The study also found that eggshells crushed by hand were not much better than nothing at all.
The calcium in the shells is released into the compost, Lalicata says.
Adding the compost to plants will provide far more benefits than just adding the shells.
