Since hosta roots crowd out the roots of weeds, they are a good choice for use as a ground cover. If you’re going to use them for this purpose, however, you need to be sure the planting site is sufficiently shady. Make sure the site you choose is not too windy. Choose a place that is sheltered from winds exceeding 35 mph (56 km/h).
Watering hostas in the morning will help keep them hydrated during hotter parts of the day during the summer. You can sprinkle mulch around the bases of the hostas to help keep the soil moist.
You can also cut hostas flowers. Whether you cut your hostas when they’re flowering or once the bloom has faded is up to you![5] X Research source
This will help maintain the overall quality of your Hostas and will make doubling your Hosta population easier.
Keep deer away by building a fence around your yard, or luring them to the edges with other deer-friendly plants. Many gardeners find that setting out shallow bowls of beer around the hostas is an effective way to get rid of slugs. Eliminate black vine weevil with an insecticide soap. Prevent nematodes by removing or drying overly wet foliate. If you see nematodes, which look like roundworms and feed on leaves, remove affected plants and destroy them.
Use fungicide spray if you see large spots with a dark border on your hostas, as this could be a sign of Anthracnose. Fight Anthracnose by preventing your hosta plants from getting too wet. If you see brown and wilted leaves along with white masses on the plant, pull any mulch away from the hostas, as this could be a sign of Sclerotium Blight. Water responsibly and prevent your hosta plants from getting too wet in order to combat Crown Rot.
