Anthuriums are beautiful tropical plants that perform well as houseplants for many gardeners. The foliage of the anthurium plant is large and distinctive and the blooms are beautifully long lasting. Provide anthurium plants with a humid growing environment, warm growing temperatures and indirect sunlight. Many gardeners transplant anthurium plants every year, as these plants tend to grow to the outer boundaries of their containers regularly. Anthuriums prefer snug surroundings and being slightly root-bound will not distress them.
Fill the larger container with three parts orchid peat, one part leaf mold, one part sphagnum moss and a handful of sand. Mix the material well with your hands.
Remove the anthurium plant from its current container carefully by loosening the soil around the container and tapping the sides of the container. Slide the plant out and place it immediately into the larger container.
Situate the anthurium plant in the larger container so the tops of the roots are approximately level with the rim of the container. Fill additional soil mixture around the roots and cover the tops of the roots with soil.
Water the newly transplanted anthurium immediately. Pay close attention to soil dryness for about two weeks and do not allow the soil to dry out. After this period, the anthurium plant can tolerate slight drying between watering.
Fertilize the anthurium two weeks after transplanting by mixing the fertilizer with water at one-quarter of the strength recommended on the package label. Fertilize again one month later and every month thereafter.
