I like to mix the plants for texture color and leaf size and also select so that some will drape over the edge as they grow and others create upper fullness. You can use smaller baskets for smaller areas.
SUPPLIES
20" wire basket
Plastic saucer
Potting soil
Moss
Plants
Combo 1: Ivy geranium Combo 2: Variegated ivy Combo 3: Mandevilla
Petunia Geranium Petunia
Lobelia Petunia Ivy or ivy geranium
Upright fuchia Alyssum Verbena
HOW TO
Water all of your plants well before starting. Add a layer of dry moss to the bottom of your basket. I mix in some wet to pack it down so soil doesn't drop through. Place your saucer on the moss. Cover with 2-3" of moist but not saturated potting soil. Start placing the trailing ivy,petunia or lobeila onto the soil at the edge of the wire basket. Work the plant through the basket so it can drape down as it grows. I like to alternate different trailing plants around the edge so the basket fills in nicely. As you add plants. be sure that you cover the roots with soil, and use slightly wet moss around the basket edge. Start adding upright plants, filling in and covering roots with soil and the edge of the basket with moss. Layer plants and soil, tucking in moss until your basket is full. How many plants you add depends upon how quickly you want a full basket. For 20" diameters, I use about 20 small plants and space them apart so they grow in.
