Hostas are very popular herbaceous perennials that usually are grown for their foliage. The leaves come in many shapes, textures and sizes. There also are several shades and colors, including combinations of white, green, blue and gold. Hostas are easy to grow and tolerate shade, so there are not as many limitations when it comes to where to plant a hosta farm. The perennials mature in four to eight years and the full size depends on the species. In addition to the colorful leaves, hostas bloom in the summer with lily-like flowers that range from white to lavender.
Choose a location that has morning sun and afternoon shade for best results. Hostas tolerate the shade but may not do as well if planted in deep shade. Plants with yellow, gold and white leaves do fine with more sun, whereas those with blue leaves need shade.
Cultivate the soil to a depth of 12 to 16 inches to prepare for the hosta farm. Add 6 inches of organic matter such as compost, manure and pine bark to make the soil richer. Work the matter into the soil.
Plan out how you want to group the hostas. Alternate size or textures, or plant similar hostas in one area to create more of an impact. Small and miniature plants look good together in one bed.
Dig a hole at least 1 foot deep. Make the width 1-1/2 times the expected size of the mature hosta. The plant's label may have this information, or ask the garden center for the information. Hosta roots grow horizontally, so the wider the hole, the better.
Remove the hosta from its container and gently loosen the roots. Tap the sides of the container if the plant is stubborn, or cut it away with shears.
Remove extra soil from the root mass by shaking it out. Put the plant in the center of the planting hole. Plant the hosta at the same depth it was in the container. Add a few inches of soil to the bottom of the hole to get the roots and leaves level to the ground, if needed.
Backfill the hole with soil. Fill it halfway and add water to eliminate air pockets. Continue filling in the rest of the hole until it's at ground level. Water the hostas until moist.
Add companion plants to hosta farms to enhance the appearance of the perennials. Early-blooming plants such as tulips, crocus, daffodils, forget-me-nots and trillium compliment hostas are good choices. Summer annuals such as impatiens also look good.
