HOSTA
Hosta, also known as Plantain lily is a popular shade plant that is grown primarily for its attractive foliage. Hardy in UDSA zones 3-9, this frost-hardy perennial is ideal for border plantings, large containers, and ground covers in shady areas. They also make great companion plants for early blooming bulbs because they hide the dying foliage.
Numerous cultivars range in all sizes from 6 inch tiny dwarfs to large cluster 2½ ft tall. The leaves can be dark or bright green, gold, yellow, blue, smooth, puckered or variegated and can grow up to 2½ ft long and wide.

Care: Once established, hostas require little care. Plant them at the same soil level as grown in the container, in rich, moist, well drained organic soil. They prefer partial shade to shade (morning sun and afternoon shade) and need protection from the hot summer sun. The bluer hostas need more shade to retain a true blue color conversely; the yellow and white leaved variety require more sun to maintain a brighter color.
Water: Give them plenty of water; they require at least 1 inch of water per week and more if grown in sandy soil. The larger leaved variety may also need more water. It’s best to water early in the day.
Feed: Fertilize in spring to mid summer at 6 week intervals (April, mid-May and July) with a balanced 10-10-10 fertilizer. Stop feeding after July to allow the plant to harden for the winter.
Hostas bloom in midsummer on tall spikes of lavender, blue, or white tubular flowers that rise above the leaves. Both leaves and flowers can be used in floral design. When finished blooming, remove the dead stalks. Hosta platanginea (Fragrant Plantain lily) is the only hybrid that produces white fragrant flowers that smell like tuberose.
Propagation: It takes 4-8 years for a hosta to reach full size. Propagate by dividing crowded clumps in the spring when new shoots appear, in the fall after the leaves die back or in August, 30 days before the first frost. They can also be started from seed but take 2-3 years before they reach blooming size and will not come true (except H. ventricosa).
Troubleshooting
Slugs and snails cause large holes in the leaves
Deer will eat the leaves down to the stem; rabbits will eat new emerging shoots.
Scorched leaves- plant needs more shade
Crown rot-outer leaves wilted and yellowed
Wilted and browning leaf tips-not enough water
