Hosta plants are perennials that are widely favoured by gardeners. They are perfect for a low maintenance landscape because of their rich foliage and ease of upkeep. Hostas originated in the Orient and were introduced to Europe in the 1700s. Today, there are over 2,500 varieties with so much variation in leaf size, shape and texture that hostas alone might fill an entire garden. Although caring for hostas is thought to be simple, understanding the basics of hosta growth is crucial in order to assist the plants realise their full potential in the garden.

Where to grow hosta plants?
Choose a location for your hosta plants that receives full to partial shade. Although most hosta species can tolerate early light, they do best in a shaded area. It’s crucial to understand that rich, organic soil is ideal for the growth of these perennials. Steer clear of hard clay soil while growing hostas as it won’t provide adequate drainage. Plant hostas where snow tends to pile up in locations that receive a lot of snowfall in the winter to preserve the stems and leaves.
Best time to grow hosta plants
Purchase dormant hostas as potted plants or as bare-root divisions, then plant them in the autumn or spring. Hostas can be planted in the summer, but they will require special care (mostly watering) to prevent summertime heat-related death.
How to grow hosta plants?
- Create a hole that is roughly twice as deep and wide as the plant’s root ball. As the roots of the hosta extend outward, it will help to loosen the soil in the planting area.
- If you are planting many hostas, place them apart based on how big you want them to get when they are mature. Hostas are skilled at occupying voids!
- Plant the seeds in the hole such that the dirt around the plant’s base, or crown, is level with the surrounding soil and that the soil’s surface shows the tips of any newly developing leaves.
- Plant hostas at the same soil level as the pot if you purchased them in a pot.
- To settle the roots, gently moisten the soil surrounding the plants with water.
Hosta: Care tips
Light
While some species of hostas may thrive in complete shadow, most thrive best in dappled sunlight for a few hours each day. Plants with variegated leaves that are green and yellow benefit from morning light exposure, which intensifies the yellow hue. Verify your hosta variety’s particular lighting needs. The plant may be receiving too much light if the leaves start to get dull, have fading spots or have brown tips.
Watering
As needed, water the hostas to maintain a damp but not wet soil. Hostas can withstand the occasional dry soil after they grow up, but prolonged droughts will not harm them. Frequent shallow applications are preferable than deeper, more infrequent watering. To keep the soil moist while growing hostas inside in pots, follow a regular watering plan.
Temperature and humidity
Hostas can grow in a variety of conditions and are not picky about humidity or temperature. Planting them in an area shielded from severe winds is ideal.
Fertiliser
One approach to increase the size of hostas is by proper feeding. A thick layer of compost added to the soil in the spring is the most effective and convenient approach to feed hostas. In addition to supplying nutrients to the soil, this also supports the soil food web. Applying a well-balanced organic fertiliser after planting or as soon as the plants start to emerge in the spring is another way to feed hostas. However, caution is needed to avoid trapping fertiliser grains in the leaves, since this may cause them to burn.
Fall and winter care
Fall hosta maintenance involves continuing to water but reducing fertiliser application. Naturally, the leaves will begin to wither back. It’s preferable to chop the plants down at that time to avoid pests or diseases getting a hold of the deteriorating leaves. Overall, hostas are resilient and do well during the winter. However, covering the roots with a layer of dry mulch might help insulate them in colder climes. For wintering outside, it’s ideal to bury potted hostas up to the lip of their containers in the garden and then cover them with mulch.
Pruning
While some farmers respect the white or purple blooms for bees and other pollinators, others cut off the flower stalks as soon as they develop. After the blooms have faded, trim off the stems if you decide to let the flowers bloom.
Hosta: Pest and diseases
Hosta suffers from many kinds of pests and diseases which attack them from time to time and rob them of their green shiny look. The slugs and snails cause holes in the leaves and a trail of silver slime across the garden. Nocturnal feeders such as flies could be controlled by beer traps. Another is the adult black vine weevil that gives irregular nicks, while its larvae destroy hosta crowns and roots resulting in wilt foliage. They are known as nematodes and these are roundworms resembling fungi or bacteria that give rise to Brown striped streaks between leaf veins.
A common leaf spot caused by anthracnose, which appears as big, irregular blotches on the foliage. Sclerotium blight infects lower parts of leaves and moves fast, resulting in yellowing, and presence of powdery, white stuff on petioles. Crown rot is caused by too much water, and it shows itself in yellowing, stunting and rotting of roots. The control measures consist of proper spacing of plants, not using wet foliage and making use of the fungicide only for a particular disease.
Hosta: Toxicity
Hostas are well-known for being low-maintenance plants. They grow quickly and require minimal care. If you have a pet, you will need to keep an eye on them near your Hostas. Hostas are harmful to pets because of the poison glycoside saponins. It may result in:
- Pain in the abdomen
- Vomiting
- Diarrhea
- Bloating
- Intestinal Twisting Distress
- Appetite loss
- Unusual heartbeat
