Hi, friends! Today I will tell you how I prepare my hostas for winter.
⚡QUICK ANSWER: Cut back the hosta leaves after the first frost, leaving about 2 inches of stems. Clean up dead foliage to prevent pests and diseases. Add a layer of mulch to protect the roots, and avoid watering during dormancy.
1. Water the hosta before winter💧
Hostas need the most water during the summer when they are actively growing. During dormancy, they still use a small amount of moisture but at a much slower rate.
In winter, hostas can’t absorb water from frozen soil, so they rely on the water stored in their tissues. This causes the plant to shrink in size. To prepare, it’s important to help the plant store enough water in autumn.
Water your hostas regularly throughout the fall until the first frost. Wait until the soil is dry at least 1–2 inches deep before watering again, and water deeply so the soil is thoroughly soaked.

2. Cut back the hostas for the winter✂️
The next step is to cut back your hostas for winter. Removing dead leaves helps clear garden debris and prevents rot around the plant.
Trim the leaves and petioles right after the first hard frost. Cut the petioles down to about 1 inch above the soil, being careful not to damage the rhizome. Always use sharp, sterilized pruning shears to make clean, healthy cuts.
3. Avoid fertilizing🚫
Do not fertilize your hostas before winter, especially with products that contain nitrogen.
If you fertilize late in the year, the hosta may stay active instead of going dormant. This can even cause young shoots to grow, which will be severely damaged by frost.
To prevent this, apply fertilizer no later than mid-summer. Always avoid over-fertilizing or using products high in nitrogen.
4. Clean the plant🧹
You also need to clean up any plant debris around the hosta, such as fallen leaves or weeds. Collect everything and dispose of it far away from your garden.
If plant debris is left to rot around the hosta, it can lead to disease and even kill the plant by spring. Rotting material can harbor pests, disease pathogens, and provides the perfect environment for nematodes to survive the winter.
5. Mulch hostas for winter🌱
You should mulch your hostas for the winter to create a more comfortable environment for them to overwinter.
Mulch helps trap heat rising from the ground, keeping the root area warmer and protecting it during hard frosts.
The best mulch is organic, such as compost or pine bark. Apply a layer at least 2 inches thick for the best protection.
6. Do not water in winter⛔
Avoid watering your hosta during the winter. In most cases, the soil is naturally wet enough, and extra water can harm the roots.
During winter, the hosta is dormant and relies on the water it stored in the fall. If you followed the fall watering routine, that will be sufficient to keep the plant healthy until spring.
