From 2 to 6 feet in diameter surrounding a tree, enabling tree roots to filter to the bottom a tree-ring planter is an area of soil. Typically described a landscape edger or by pavers, the planter protects the tree from weed- mower or trimmer injury. The planter gives a little backyard zone throughout the tree and retains mulch on the tree roots. Add crops to the tree-ring planter for erosion protection, soil enhancement and shade.
Hostas
Hostas provide green foliage in a tree-ring planter. These moisture-loving perennials prosper in partial to full shade under trees as well as in woodlands. Grown in Sunset Climate Zones 4 cultivars from 6″ up to 3-feet tall mature as mounds of variegated and green leaves. Mulching the planter with 2 to 4″ of bark or wood chips retains soil moisture, benefiting the tree as well as the hostas. Hostas grow gradually and need little treatment apart from slug and snail control. Leaves die in autumn for winter dormancy.
Bulbs
Bulbs companion nicely using a deciduous tree-ring planter. Use bulbs that are tiny as their planting holes reduce harm to the tree roots. Plant daffodils (Narcissus), crocuses (Crocus), dwarf iris (Iris reticulata) and grape hyacinth (Muscari) or windflower (Anemone blanda) for late-winter and early spring colour. These bulbs sprout ahead of the tree blocks sunlight and entirely leafs out. The bulbs don’t require an additional layer of soil as they may be including oxygen may be blocked by soil from tree roots and below ground.
Annuals
Flowering annuals provide variety to your own tree ring planter. Grown from bedding plants or seeds, shade- annuals carpet the tree-ring planter with flowers and greenery. For quick-filling summer shade, select begonias (Begonia semperflorens cultorum) with variegated foliage 12 months, and plant masses of impatiens (Impatiens) still another yr or plant waves of colour ranging from cream and yellow to bright red flowers across the tree.
Ground cover
Groundcovers fill a tree-ring planter with steadily decomposing to enrich the soil, guarding the floor from erosion and living mulch. Monkey grass, a ground cover including liriope (Liriope muscari) and mondo (Ophiopogon japonicus) types, grows in Sunsetâs Environment Zones 5 through 2-4. The clumping cultivars type mounds of abandon that need little treatment and thrive in shade. Other groundcovers are organic types like mint (Mentha), sweet woodruff (Galium odoratum) and chamomile (Anthemis nobilis), that develop as annuals in cool climates and perennials in temperate climates. Trimmed and fragrant for uses groundcovers that are natural appreciate shade to partial sunlight.
