egg shells

Widely used to chase away all the undesirables that revolve around plants, eggshell is also a natural fertilizer rich in calcium and potassium. By crushing the shells very finely and sprinkling them on the bark of your orchids, the soil will quickly absorb all these nutrients and minerals essential for flowering.

Ash

Do you like creating a cozy atmosphere in winter around the fireplace? So little tip, don’t get rid of the ashes! You may not know it, but you can recycle them into fertilizer for your orchids. It may seem strange to you, but fireplace ashes are very rich in calcium, potassium, phosphorus and trace elements. In other words, a cocktail of nutrients that your plants need!

The ideal is to add these ashes directly to your orchid’s soil. Do this after watering. The ash tree favors flowering and also takes advantage of this to asphyxiate insects that revolve around the plants. However, they lack  nitrogen and phosphorus, which you will need to supplement with other fertilizers. Caution: Since ash is a bit caustic, it’s best to wear gloves when handling it.
