    Quick Care Guide

    Care Difficulty: This plant has easy care needs.

    Light requirements: A sunny windowsill with bright light will suit this plant best. Too much sun can cause scorching.

    Watering: Drought tolerant, water thoroughly and allow the soil to dry out between waterings. Reduce watering further in winter, Myrtillo geometrizans do not like to sit in water.

    Humidity: Prefers a dryer spot and dislikes cold draughts. Avoid placing it in more humid rooms such as kitchens and bathrooms, as this can cause problems to your plant.

    Toxicity: Non-toxic to humans and pets - but does have very sharp spines- be careful when handling.

    Feeding: Apply a liquid fertilizer once a month during spring and summer (growing season) but reduce it in winter. Follow the instructions on the fertilizer packaging for the dilution ratio.

    Repotting: Repot when roots have filled the pot and are growing out of the container. Size up one to two inches bigger than its current container using a cacti/succulent mix. Make sure the pot has adequate drainage holes.
