How and when to plant pampas grass
Pampas grass, known botanically as Cortaderia selloana, is an impressive ornamental plant thanks to its large, fluffy plumes that appear in autumn. It is hardy, easy to maintain, and adds an exotic look to any garden. For healthy growth, it is important to plant it at the right time and under the right conditions.
When is the best time to plant pampas grass?
The optimal time for planting is in spring, during April–May, once the risk of frost has passed, or in autumn, from September to early October. This allows the roots enough time to establish before the heat of summer or the cold of winter.
Where to plant pampas grass
Pampas grass prefers sunny, warm locations. A well-drained, fertile and loose soil is recommended. Avoid waterlogged areas or heavy clay soils. The plant also needs space, as it can become very large and reach heights of two metres or more.
How to plant pampas grass step by step
- Dig a hole twice as wide as the root ball.
- Place the plant in the hole, making sure the top of the root ball is level with the soil surface.
- Fill the hole with garden soil mixed with compost or well-rotted manure.
- Firm the soil lightly and water generously after planting.
Aftercare
- Water regularly during the first year until the plant is well established.
- Apply a mulch layer around the base to retain moisture and protect the roots from winter cold.
- Cut back the plant at the end of winter or the beginning of spring to stimulate new leaf growth.
Summary
Pampas grass is best planted in spring or autumn, in a sunny spot with fertile, well-drained soil. With correct planting and minimal care, pampas grass will bring a spectacular decorative effect to your garden, especially in the autumn season.
