I have planted about 4 types of Hosta's in my landscaping over the past several months. One of the varieties keeps having leaves turn brown and dry up. All of my Hosta's get direct sun until about 2:00pm. Is that too much sun? Not enough?
I also used to water my landscaping every morning and that is when I noticed some of the leaves turning brown. Am I watering them too much? because I stopped watering them about a week ago to see if I noticed a difference, but the leaves are still turning brown. I have always heard that you can't go wrong with Hosta's because they are one of the easiest plants to grow. Well, I have somehow found a way to mess up that theory. What do I do?

Hostas are great garden plants that will add texture and color to shady or semi-shady spots in your garden. Actually, hostas will take a pretty good amount of sun as long as they receive adequate water.
Hostas can be purchased either in containers or as bare root plants.

Bare root hostas should have their roots soaked in water for a couple of hours before planting to re-hydrate the root systems. Hostas prefer nice light, loose garden soil, so add lots of organic matter to your planting area when you are putting in hostas.

Hostas will appreciate a water-soluble fertilizer at planting time and monthly during the growing season.

Large hostas are easy to dig and divide in the spring time when the leaves are just emerging and are still pencil sized, in fall as the leaves begin to yellow or even in the early summer as long as you have good soil conditions and keep them well watered.

Just lift the entire clump and separate the roots. Some of the smaller root pieces on the outer perimeter of the plant will pull apart easily. You can also cut the root system into pieces using a sharp knife, a serrated bread knife or a hacksaw.

Hostas generally prefer dappled shade. They definitely prefer morning sun (1/4-1/2 of the morning) hot afternoon sun will scorch hostas. Generally the green forms can take a little more sun than the golds and blues. The more organic matter and moisture there is in the soil, the more sun they can take.

Hostas do need lots of moisture, once again just generally, the waxier, thicker leaved forms are slightly more drought tolerant, but dry conditions will lead to scorch and the eventually demise of the plant. Water hostas deeply and thoroughly every few days depending on the sun and heat; frequent shallow irrigation will encourage surface roots that will be susceptible to drought and may lead to crown rot.

Slugs love hostas. To protect your hostas from slug damage, you can set out baits for the slugs. Use a tuna can, dig a hole near your hostas and sink the tuna can in it up to the rim. Fill the can with beer and the slugs will be attracted to the smell. They will fall in and meet their demise. Or you can use grapefruit halves. Hollow the grapefruits, and place them cut side down in the garden. The slugs will crawl under them during the night. Go out early in the morning, lift the grapefruits and squish the slugs or put them in a bucket of soapy water. The Hosta Society also recommends a vinegar spray. Mix one part white vinegar to four parts water and spray the leaves and surrounding area with the solution.

Some hostas will tend to look pretty sad by the end of summer, especially if it has been a dry year. You can go ahead and cut back the foliage in late summer if the plants look ratty.
