An abundantly flowering hanging basket can create a striking focal point for a porch, patio or deck. Learning how to weave annual flowers into the sides and bottom of a basket design can transform a simple hanging basket into a cascade of summer color. Making a fully planted hanging flower basket is a fun and easy project for most container gardeners. Select flowers that grow robustly and bloom well in your location.
Select a sturdy wire basket that is large enough to accommodate 8 to 10 plants. These types of wire baskets are sold at most large department stores and home garden centers.
Open a bag of sheet moss and immerse several handfuls in a bucket of water. You want your sheet moss to soften and absorb water before you use it in your basket. Allow your sheet moss to soak for 10 to 15 minutes.
Place wet sheet moss about 4-inches in diameter at the bottom center of your wire frame. Because hanging baskets come in many shapes and sizes, this is a general estimate. You want to cover the bottom of the basket to where the frame starts to curve upward.
Remove plants from their containers and position them around the edge of the sheet moss. The plant foliage should be carefully inserted through the frame so that the foliage is outside the planting frame, with the roots inside. Fill in holes between the plants with more sheet moss. The sheet moss is critical as the glue that holds your planter together. Use it fill holes and to prevent potting soil from running out when you water.
Fill the level with potting soil even with the plants so that your plants are secure before you build your next row of sheet moss and more plants. Continue to fill the sides of the planter with flowers that grow well in your area. Fill the inside of the planter with potting soil with a few plants across the top of the planter to finish it off. Be generous with your sheet moss so that your soil doesn't leak out.
