Starting Hostas From Seed
Most hostas begin in the garden as bare-root stock or potted plants, but it is possible to grow them from seed. Hosta cultivars do not come true from seed, except for Hosta ventricosa. Seed germination rates may be low, so it is best to start with several seeds.
Harvest ripe seed pods, remove the seed kernels, and dry them out before storing them in plastic bags in the refrigerator for about four weeks. This tricks the seeds into thinking they have gone through winter dormancy and helps with germination. Alternatively, sow the seeds outside in late summer to fall for a “natural” cold treatment over winter.
For indoor sowing, use seed-starter trays with humidity domes and starter mix. The seeds do not need light to germinate, but they require warmth and moist soil. Germination can take up to three weeks. After two leaves appear, remove the humidity dome and place the plants under grow lights for 18 hours a day. Cull weak plants and transplant healthy ones to larger pots. Introduce healthy plants to the outside gradually through hardening off. Seeds started during winter should be ready for the garden by the following spring or summer.
Starting Hostas From Seedlings
Most gardeners prefer starting hosta plantings with young, potted plants. Choose a location that gets morning sun but is shaded in the afternoon. Prepare the planting area by turning over the soil to a depth of about 12 inches and adding organic matter such as compost or leaf mold.
To plant a hosta, dig a hole that is twice the width of the root ball and as deep as the root ball. Carefully remove the plant from the pot and untangle the roots with your fingers. Place the plant in the hole and backfill with the soil that was removed, making sure that the top of the root ball is level with the surrounding soil. Avoid burying the crown, as this can cause the plant to rot. Gently tamp the soil around the plant to eliminate air pockets, then water thoroughly and add 2-3 inches of mulch around the base of the plant, being careful not to let the mulch touch the stem. Check the plant tag for spacing recommendations, which are usually 1-3 feet apart.
Most hostas can grow as perennials in USDA plant hardiness zones 3-9. Hostas are shade-tolerant plants, but they can tolerate direct sun in cooler climates with sufficient water. Plants with gold coloring need sunlight to develop their color. In warmer climates, hostas need shade in the afternoon to avoid papery, brown leaf edges. Plant hostas in the spring, preferably on a cloudy day, or in the summer as long as they are well-watered. Give them at least 30 days to establish their roots before cold weather sets in.
Hostas prefer fertile soil that drains well and has a pH of 6.5 to 7.5. Test the soil before planting to determine necessary amendments. Work in organic matter like compost or leaf mold to add nutrients, promote drainage, and loosen the soil. Apply a balanced, slow-release fertilizer in the spring, being careful to keep it away from the foliage and crown. Hostas prefer dappled shade with morning sun and afternoon shade, or afternoon shade in warm climates. Keep the soil moist but not too wet, supplementing rainfall as necessary.
Hostas can be divided every 3-5 years to create new plants and relieve overcrowding. Divide mature plants in the spring as they begin to show signs of growth.
To divide a plant, dig around it and remove as much of the root system as possible. Clean the roots and use a garden knife to divide the plant into two or three sections. Cut away any dead parts and replant in the garden. Hostas should be cut back after a hard frost and debris removed to prevent disease and insect infestation. Deer, slugs, rabbits, and aphids can all be a problem for hostas, but there are deterrents and natural predators that can help. Anthracnose and sooty mold are common diseases for hostas, but maintaining good air circulation and removing damaged leaves can help prevent their spread.
FAQ
1. What are hostas?
Hostas are perennial plants that are known for their large, lush foliage. They are commonly grown in gardens and are prized for their ability to thrive in shade. Hostas come in a variety of colors and sizes, making them a versatile and popular choice among gardeners.
2. Where should I plant hostas?
Hostas prefer to be grown in shade or partial shade. They can tolerate some morning sun, but too much direct sunlight can scorch their leaves. It’s best to choose a location that receives dappled sunlight or is shaded by trees or buildings. Hostas also prefer moist, well-draining soil.
3. How do I prepare the soil for planting hostas?
Before planting hostas, it’s important to prepare the soil properly. Start by removing any weeds or grass from the area where you plan to plant them. Then, loosen the soil using a garden fork or tiller. Add organic matter, such as compost or well-rotted manure, to improve the soil’s fertility and drainage.
4. How often should I water hostas?
Hostas have shallow root systems, so they require regular watering to keep the soil consistently moist. Water them deeply once or twice a week, depending on the weather and soil conditions. Avoid overwatering, as this can lead to root rot. Mulching around the plants can help retain moisture in the soil.
5. How do I divide hostas?
Hostas can be divided to create new plants or to rejuvenate older clumps. The best time to divide hostas is in early spring, before new growth begins. Carefully dig up the clump and separate it into smaller sections, making sure each division has several healthy shoots and roots. Replant the divisions in prepared soil, spacing them apart to allow for future growth.
6. How do I prevent pests and diseases on hostas?
Hostas are relatively pest-resistant, but they can be susceptible to slugs and snails. To prevent these pests, you can use organic slug baits or create barriers, such as copper tape, around the plants. In terms of diseases, hostas can be prone to foliar nematodes and crown rot. Proper sanitation, such as removing infected leaves and improving air circulation, can help prevent these issues.
7. When do hostas bloom?
Hostas typically bloom in mid to late summer. The flowers are usually tubular or bell-shaped and come in shades of white, lavender, or purple. While the flowers are an added bonus, many gardeners grow hostas primarily for their foliage. If you want to encourage more blooms, you can remove the flower stalks after they have finished blooming.
