Whether your space is large or small, monkey grass could be the ideal plant to try this year, whether for lining pathways, growing under large trees, or simply as an evergreen accent in your flower beds.
'Liriope is a resilient choice for borders or as ground cover,' shares Mike Murphy, a gardening expert and owner of You Had Me At Gardening.

'Once established,' he notes, 'liriope is quite low-maintenance.'
This hardy and tough evergreen perennial can grow well in various conditions. Generally, you can cultivate monkey grass within US hardiness zones 4 through 10, tolerating both extreme cold and heat. It also exhibits drought tolerance for brief periods. Planting in a moist, partially shaded area will yield the best results.

Essential Tips for Growing Monkey Grass

- Soil: 'Liriope, or monkey grass, flourishes in well-drained soil,' advises Mike. They prefer moist yet well-draining conditions, so it's wise to avoid overly soggy spots. Although monkey grass can withstand brief periods of drought, applying a layer of mulch or bark chips in the fall can enhance the quality of dry soil. 'Mulching around the plants helps retain moisture and suppress weeds,' Mike adds.
- Light: This plant is 'adaptable to various light conditions,' says Mike. It is 'particularly tolerant of shade, making it an excellent choice for areas with filtered sunlight or partial shade.' This adaptability is why many garden designers and gardeners favor monkey grass for tricky spots like planting beneath trees. Interestingly, in addition to thriving in shade, liriope can also handle full sun, making it a versatile option for different garden settings.
- Watering: After planting, ensure that you regularly water your liriope, especially during warm spells. This is particularly important during the first year after planting. Mike emphasizes that monkey grass thrives with 'consistent, deep watering.'
- Fertilizing: When considering how to feed monkey grass, Mike suggests using 'a balanced fertilizer in spring and summer to support healthy growth.' He warns against over-fertilizing, as this can lead to excessive foliage at the cost of blooms. Always adhere to the fertilizer instructions, ensuring the right amount is diluted in water, and repeat only as often as recommended. As Mike points out, too much fertilizer can yield more foliage while compromising flower production.
- Pruning: 'Liriope is a grass-like plant that benefits from pruning to maintain its tidy appearance,' Mike explains. This is best done in 'late winter or early spring before new growth begins.' While 'mowing is not recommended, you can use hedge trimmers to cut back the foliage to a few inches above ground.' Alternatively, a slower, more traditional approach is to use secateurs, trimming back the foliage and leaving small monkey grass clumps one to two inches above ground.

Can I Grow Monkey Grass in Full Shade?
