If your hanging baskets are becoming overgrown and leggy, it is possible the plants require extra growing room. Transplant hanging baskets to renew the plants and give them ample space to grow. Use high quality potting soil, rich in organic matter, to provide adequate nutrients to your hanging plants. This will help ease them through the transition time and encourage new and active growth.
Prepare the larger hanging baskets for planting. Cover the bottom inch of the baskets with gravel and fill the baskets approximately halfway with potting soil.
Remove the plants from the existing planter. Place the plants onto the tarp and examine them for health and vitality. If you find plants that appear dead or dying, separate these from the viable plants and discard them. Pull apart the plants gently to separate the root systems so you can plant them properly again.
Place the plants carefully into the new hanging basket. Arrange the plants so they will have adequate growing room in the new planter with approximately 3 inches between each plant. Do not overcrowd the basket. Arrange the plants around the perimeter of the basket and add one to the center.
Make sure the planting depth of the plants is not too deep. Add more potting soil, if necessary, so the tops of the plants will be about even with the rim of the basket. Fill in additional potting soil around the plants and add a light layer of potting soil over the tops of the plants. Firm the potting soil down gently with your hands.
Water the newly transplanted hanging basket generously immediately after planting.
Hang the hanging basket back in the growing location.
Keep the hanging basket evenly moist to prevent the transplanted plants from drying out. This may require daily watering or watering every other day, depending upon the sun exposure and outside temperature.
