How do you keep hostas from getting too big?

Keeping hostas from getting too big is a common concern for gardeners who want to maintain a neat and well-manicured garden. Fortunately, there are several effective methods for controlling the size of hostas and keeping them in check. One of the most important steps in preventing hostas from becoming too large is dividing them regularly.

Dividing hostas not only helps to control their size but also promotes their overall health and vigor. The best time to divide hostas is in early spring, just as new growth begins to emerge. Here’s a step-by-step guide on how to divide hostas properly:

1. Prepare the area: Before dividing hostas, prepare the area where you will be replanting them. Clear away any weeds or debris and loosen the soil to ensure good drainage. Adding organic matter, such as compost or well-rotted manure, can also improve the soil quality.

2. Dig up the hosta clump: Use a garden fork or shovel to carefully dig up the entire hosta clump. Be sure to dig deep enough to get underneath the roots and lift the clump out of the ground. Gently shake off any excess soil to expose the root system.

3. Divide the clump: Once the hosta clump is out of the ground, you can divide it into smaller sections. Look for natural divisions or growth points within the clump, which usually appear as separate crowns or shoots. Using a sharp knife or garden tool, carefully separate these sections, ensuring that each division has a good portion of both roots and foliage.

4. Trim away dead sections: While dividing the hosta clump, take the opportunity to remove any dead or damaged sections of the plant. This not only improves the overall appearance but also reduces the risk of disease or pest infestation. Trim away any yellowed or browned leaves and discard them.

5. Replant the divisions: Once the hosta clump has been divided and dead sections removed, it’s time to replant the divisions. Dig a hole that is wide and deep enough to accommodate the root system of each division. Place the division in the hole and backfill with soil, firming it gently around the roots. Water the newly planted divisions thoroughly to help settle the soil.

6. Provide proper care: After dividing and replanting hostas, it’s important to provide them with proper care to ensure their successful growth. Water the divisions regularly, especially during dry periods, to keep the soil evenly moist but not waterlogged. Applying a layer of mulch around the plants can help retain moisture and suppress weed growth. Additionally, fertilize the hostas with a balanced slow-release fertilizer in early spring and again in midsummer to provide essential nutrients for healthy growth.

Dividing hostas every few years, or when they become overcrowded, not only keeps them from getting too big but also rejuvenates their growth. It allows for better airflow and light penetration, reducing the risk of disease and promoting overall plant health.

In conclusion, to keep hostas from getting too big, regular division is key. By dividing hostas in early spring, removing dead plant sections, and providing proper care, you can maintain their size and shape while ensuring a thriving and visually appealing garden.
