Summer Care for Your Hostas

Summer Care for Your Hostas

Hostas are a beloved staple in many shade gardens, known for their lush foliage and low-maintenance nature. However, summer’s heat and occasional dry spells can stress even the hardiest hostas. At Humble Hen Farm, we’re passionate about helping your garden thrive. Here’s your guide to keeping hostas healthy and beautiful all summer long.

1. Watering Wisely

Hostas love consistent moisture, especially during the hot months. Deep watering once or twice a week is better than frequent, shallow watering. Aim for about one inch of water per week, adjusting for rainfall. Early morning is the best time to water, helping prevent fungal diseases.

2. Mulch for Moisture and Cool Roots

Applying a 2-3 inch layer of organic mulch, like shredded bark or leaf compost, helps retain soil moisture and keeps roots cool. Mulch also suppresses weeds, which compete for water and nutrients. Be sure to keep mulch a couple of inches away from the base of the plant to prevent rot.

3. Protect from Harsh Sun

While most hostas prefer shade or partial shade, some varieties tolerate a bit of morning sun. However, afternoon sun can scorch leaves, causing brown edges and faded color. If your hostas show signs of sunburn, consider relocating them or providing temporary shade with garden fabric or umbrellas.

4. Fertilize for Growth

Hostas benefit from a balanced, slow-release fertilizer applied in early summer. Avoid over-fertilizing, as it can lead to lush but weak growth. Always water after fertilizing to help nutrients reach the roots.

5. Keep an Eye Out for Pests

Slugs and snails are the most common pests for hostas, leaving behind tell-tale holes in the leaves. Use organic slug pellets, crushed eggshells, or diatomaceous earth around plants to deter them. Check under leaves regularly for pests like aphids or spider mites.

6. Manage Fungal Diseases

Humid summer weather can encourage fungal diseases like leaf spot. Remove and dispose of infected leaves, and avoid overhead watering to keep foliage dry. Good air circulation is key, so avoid overcrowding your plants.

7. Prune Damaged Leaves

Remove yellowed, scorched, or damaged leaves throughout the summer to keep your hostas looking tidy and to prevent disease spread. Use clean, sharp scissors or pruners.

8. Divide and Replant (If Needed)

If your hostas are crowded or not performing well, you can divide them in early summer. Dig up the clump, split it into sections, and replant. Water thoroughly after replanting.

9. Monitor Soil Health

Hostas thrive in rich, well-drained soil. Add compost or organic matter as needed to maintain soil fertility and structure.

10. Enjoy Your Garden!

Hostas reward a little summer TLC with vibrant, healthy foliage. Take time to enjoy their beauty and the lush, relaxing atmosphere they create in your garden.
