Coconut fiber has grown in popularity as a viable alternative to sphagnum peat moss. Coconut fiber liners for use in hanging baskets are both functional and attractive. They retain soil, nutrients and water for plants growing in them. Coconut fiber liners are sold in several sizes, so you may have to cut them down to fit whatever baskets you decide to use. A word of caution: coconut liners dry out more quickly than many containers do, so you will have to water them more often to keep your plants healthy.
Choose a hanging basket that is not solid or woven tightly in order to show off the coconut liner. This way the coconut liner is part of your design scheme.
Select a coconut liner the same shape as your selected hanging basket, but slightly taller. If it is much taller, cut it down so that it is only 1 inch taller than the basket.
Place the liner inside the basket, pushing it into place so that it lines the basket as closely as possible.
Fill liner half full with potting soil.
Transplant plants into the hanging basket, starting with any plants you want to place along the outside. Work your way toward the inside, taking care to fully cover each transplant's root balls with soil. Squeeze the pots lightly to loosen the root balls, then place each plant into a hole the same depth as the root ball.
Water the soil until the coconut liner is damp to the touch, but not dripping. Hang outside, or somewhere acceptable to get wet if the basket drips. Choose a location according to the light needs of your plants.
Repeat entire process as necessary for remaining hanging baskets. Fertilize regularly with plant-appropriate fertilizer according to package instructions. Add water whenever the coconut liner feels dry.
