watering

Limestone calamint (Clinopodium arkansanum) should be watered about once a week during the warmer months of spring and summer, ensuring the soil remains moist but not wet. During the winter months, it is best to water every 2 weeks instead, allowing the soil to dry slightly between waterings. During extremely cold weather, water this plant only once a month. Be sure to check the moisture level of the soil before watering. When water is needed, it should be applied slowly and evenly over the root zone. Too much water can lead to root rot, so be careful not to overwater.

sunlight

Limestone calamint (Clinopodium arkansanum) grows best in full sunlight and requires between 6 and 8 hours of direct sun daily. This plant species typically does best during the late spring and summer months when the amount of sunlight it receives is more consistent and direct. It is important to make sure that limestone calamint is receiving enough sunlight each day; however, be aware that this plant can be sensitive to too much sun and the leaves may be burned with excessive direct sunlight. It is best to provide limestone calamint with either morning or late afternoon sun, or any combination of the 2.

pruning

Limestone calamint should be pruned yearly in the late spring/early summer when the buds have set but before flowering begins. Dead wood should be pruned away at any time during the growing season. For general maintenance, prune the plant lightly by removing dead or faded flowers as well as any tips that are weak or broken. This should be done throughout the growing season to encourage new and lush growth. To maintain a fuller, more compact shape, prune the plants back after flowering has finished. Finally, remove any spent flowers or any dead wood promptly to prevent any diseases from developing.
