Tips for Keeping Your Plants Healthy

Pampas grass is a large and hardy plant, but it still needs some TLC to stay healthy. Here are a few tips for keeping your pampas grass plants healthy and looking their best:

  • Water regularly. Pampas grass prefers moist soil, so water your plants about once a week, or more often if the weather is particularly hot or dry.
  • Fertilize in the spring. Apply a balanced fertilizer to your pampas grass in early spring to help encourage new growth.
  • Prune in late winter. Cut back any dead or Brown leaves from the previous season in late winter or early spring.
  • This will help promote new growth and prevent problems with pests or diseases.

Lighting and Temperature

Pampas grass prefers full sun, but can tolerate some shade. It will grow best in areas with warm summers and cool winters.

Pruning is important to prevent pampas grass from becoming too large and unmanageable. Pampas grass should be pruned in early spring before new growth begins.

To prune, simply cut the grasses back to about 24 inches tall.

First, after pruning the plant all the way to the ground, use a shovel to cut through the root system. Next, gradually dig up the clump until it can be lifted off the ground.
