Why Winter is the Best Time to Cut Back Ornamental Grasses
When to cut back ornamental grasses is a common question for gardeners. The best time is typically during the winter months, between January and March, when the plants are dormant. During this period, ornamental grasses are “sleeping” and not actively growing, which makes it the ideal time to cut them back without harming new growth.
Trimming ornamental grasses during dormancy offers several benefits:
- Prevents Fungal Diseases: Leaving dead growth on the plant can trap moisture, leading to fungal problems.
- Avoids Pest Infestations: Old growth can serve as a hiding spot for pests, which may damage the plant.
- Clears the Way for New Growth: By cutting them back, you allow fresh shoots to grow in the spring, making the plant stronger and healthier.
If you’re unsure how to manage other aspects of your landscape during this time, you can always rely on professional winter pruning services for expert advice and care.
Which Ornamental Grasses Should You Cut Back?
Not all ornamental grasses require cutting back in the same way. Here’s a list of common ornamental grasses that benefit from a late winter trim:
- Pampas Grass: This tall grass can grow up to 10 feet high. In late winter, trimming it back keeps it looking neat and encourages new, lush growth.
- Dwarf Pampas Grass: Ideal for smaller gardens, this grass grows 3-5 feet tall. Cut it back in late winter to maintain its tidy appearance and vibrant new growth.
- Muhly Grass: Both Pink and White Muhly grasses bloom in fall and reach 3 feet tall. Cutting them back in winter clears out old stems, ensuring beautiful blooms next season.
- Miscanthus: Varieties like Adagio, Cosmopolitan, and Gracillimus benefit from a trim in late winter. Cutting back ensures the plant looks clean and ready to thrive in spring.
- Liriope (Lilyturf): Whether it’s Royal Purple or Variegated Liriope, trimming it back in winter helps remove ragged leaves, promoting fresh growth.
- Mondo Grass: This low-growing grass, perfect for ground cover, should be trimmed to keep it neat and prevent tangling.
By trimming these grasses in late winter, you’ll help them grow back strong and beautiful for the upcoming season. If you need assistance with other landscaping needs, such as flower bed maintenance, consider reaching out to professionals for help.
The Best Time to Cut Back Your Ornamental Grasses
Timing is everything when it comes to cutting back ornamental grasses. As mentioned earlier, the best time is between January and March. The reason for this is simple: you want to trim your plants while they are still dormant and before new growth begins in the spring.
If you cut too early, you risk damaging the plant if a late frost occurs. On the other hand, cutting too late means you might remove fresh, tender shoots that are essential for next season’s growth. Aim for that sweet spot when the grass is fully dormant, but before new shoots start appearing.
Tools You’ll Need for Cutting Back Ornamental Grasses
Having the right tools will make the job easier and faster. Here’s a list of what you’ll need:
- Hand Pruners or Garden Scissors: For smaller grasses like Liriope or Mondo Grass.
- Hedge Shears or Power Hedge Trimmer: For larger grasses like Pampas Grass or Miscanthus.
- Gloves: Some grasses have sharp edges, so protective gloves are essential.
- Wheelbarrow or Yard Bags: To collect all the trimmings.

Dividing Ornamental Grasses
