How to Care for Mountain Mint

Before you buy Mountain Mint, make sure to read about the recommended care instructions to keep this plant healthy and thriving.

How do I plant Mountain Mint?

How do I plant Mountain Mint?

We suggest when planting your newly purchased Mountain Mint plants that you dig a hole twice as wide as the root system but not deeper. The most common cause of plant death after transplanting is planting the new plant to deep. A good rule is that you should still be able to see the soil the plant was grown in after back-filling the hole. Mountain Mint prefers drier soils so there is a less of a need to worry about mulch.

How do I water Mountain Mint?

How do I water Mountain Mint?

After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Mountain Mint a good deep watering. Go slow, much of the water you put on the plant at first will run away from the plant until the soil is soaked. A general rule of thumb is to count to 5 for every new plant in a mass planting of 1 gallon Mountain Mint. Check the plant daily for the first week or so and then every other day there after. Water using the counting method for the first few weeks.

How do I fertilize Mountain Mint?

How do I fertilize Mountain Mint?

We recommend feeding your Mountain Mint in the very early spring and again in mid summer after all new growth has hardened off and it begins to set flower buds. Espoma Flower-tone will give the plant a boost of nitrogen that will be needed for healthy foliage.

Do I need to deadhead Mountain Mint?

Do I need to deadhead Mountain Mint?

Mountain mint can spread through self-seeding, so deadheading spent flowers prevents seeds from forming and potentially leading to unwanted plants. Deadheading encourages the plant to produce more flowers by removing the energy-sapping spent blooms. Remove the spent flower heads regularly, especially during peak flowering.
