The beauty of kokedama and how to care for a moss ball

Q: What is a kokedama?

Need to Know: A kokedama is a plant grown in a moss-covered ball of soil tied with string or fishing line. It comes from Japan and can sit on a dish or hang in a window. The Missouri Botanical Garden describes kokedama as the Japanese art of growing plants in a moss-covered ball of soil wrapped with string or monofilament fishing line. The Royal Horticultural Society (RHS) calls it a type of Japanese hanging bonsai and suggests it as a fun afternoon project. There is no pot, so the moss ball is both container and display. You can rest one on a shallow dish, set it on a small stand or hang it on a string where the plant gets the light it likes.

Q: Which plants work well as kokedama?

Need to Know: Small, slow-growing houseplants with compact roots suit a moss ball best. Pothos, philodendron, ferns and peperomia are good first choices. Missouri Botanical Garden suggests choosing plants with small root systems or slow growth. Its list is grouped by light: Which plants work well as kokedama? Shade to bright indirect; Pothos, philodendron, ferns, peperomia, begonia, prayer plant, creeping fig Part sun to full sun; Kalanchoe, aloe, string of beads, wax plant, basil, thyme University of Illinois Extension adds dracaena, spider plants and even small orchids, and notes that succulents work too and need less water. If you are new to plants, our list of beginner plants that still look good includes several that make lovely first balls.

Q: What do I need to make one?

Need to Know: Potting mix, moss, a plant and strong string are enough. Synthetic string or fishing line lasts longer, because natural fibers break down with repeated soaking. Missouri Botanical Garden lists potting soil, peat moss, sphagnum sheet moss, waxed string or fishing line, scissors, a bowl and gloves. University of Illinois Extension uses a mix of about 70% potting mix or peat moss and 30% akadama, a clay-like bonsai soil. The basic steps: Dampen the soil until it holds together when pressed firmly; Shape a firm ball; Missouri Botanical Garden suggests tossing it in the air a few times to make sure it holds; Remove the plant from its pot, shake off old soil and set the roots in the center of the ball; Wrap the ball in damp moss and tie it in place with string, wrapping in all directions; Leave a long tail of string at the top if you want to hang the ball String choice matters. The Brooklyn Botanic Garden recommends waxed thread or another durable cord and advises avoiding cotton, jute or hemp, which tend to break down after repeated waterings.

Q: How do I know when my kokedama needs water?

Need to Know: Lift the ball: a light ball means the answer to does this plant need water today is probably yes. Moss balls dry faster than pots, so the check comes up more often. University of Illinois Extension gives two easy signals. Push a finger into the top of the ball near the base of the plant to feel whether the soil is dry, and notice the weight of the ball. If the ball feels light, water. Missouri Botanical Garden uses the same weight test. After a few soaks you will learn how heavy a freshly watered ball feels, and the check becomes second nature. Between soaks, Illinois Extension suggests misting the moss to keep it from drying out completely.

Q: How do I water one without a mess?

Need to Know: Soak the whole ball in lukewarm water until it feels heavy, then let it drip before you hang it or set it back. Draining keeps water off furniture and keeps the core from staying soggy. Fill a bowl, bucket or sink with lukewarm water and gently push the ball under so it starts to absorb water. Sources give different soak times: Missouri Botanical Garden: 5 to 10 minutes, or until the ball feels heavy; University of Illinois Extension: 15 to 20 minutes, fully submerged; Brooklyn Botanic Garden: 20 to 30 minutes The common thread is weight. Once the ball feels heavy, lift it out, gently squeeze out extra water, and let it drip dry before it goes back on display. A soggy core for days on end is the same problem as a pot that never drains; our overwatering guide explains why roots need air. Constantly damp moss and soil can also attract fungus gnats.

Q: Where should a kokedama live?

Need to Know: Give it the light its plant likes, out of hot direct sun and away from heating and cooling vents. Strong sun and drafts dry a moss ball very quickly. University of Illinois Extension says the right light depends on the plant inside, and advises avoiding full sun locations because they dry the moss ball too quickly. Keep the ball away from hot or cold drafts as well. Our guide to choosing your first plant explains how to read the light in each window. Hanging balls can drip after a soak, so pick a spot where a few drops do no harm or place a tray beneath. Missouri Botanical Garden notes that outdoor kokedama with hardy plants are more challenging because of frequent watering and winter needs, so indoor plants are the easiest start.

Q: How do I feed a kokedama?

Need to Know: Add houseplant fertilizer at half strength to the soaking water while the plant is growing. A small ball holds few nutrients, and diluted feed is gentle on roots. The University of Illinois Extension kokedama fact sheet suggests mixing indoor plant fertilizer into the soaking water at half the recommended strength, or adding a slow-release fertilizer to the soil when you make the ball. Missouri Botanical Garden also feeds through the water bowl with a water-soluble fertilizer. Fertilizer labels list three numbers: nitrogen, phosphorus and potassium. A general houseplant fertilizer at half strength suits most kokedama plants.

Q: What do I do when the plant outgrows its ball?

Need to Know: When a well-watered, well-fed plant starts to look stressed, it is ready for a bigger ball or a pot. Roots that fill the ball leave little room for water. Missouri Botanical Garden says that if the plant has grown large and looks stressed even with good watering and feeding, it may be time to move to a larger ball. Unwrap the old string, add fresh soil around the root ball, and wrap it again in new moss. Moving the plant into a pot is a perfectly good choice too. Check the string from time to time as well. Loose or broken string lets the ball slump, and retying keeps everything snug.

Q: Is kokedama right for me?

Need to Know: Kokedama suits someone who enjoys a hands-on watering ritual and a living sculpture. It asks for more frequent checks than the same plant in a pot. Kokedama is a joy if you like handling your plants and enjoy the look of a green sphere in the window. It makes a thoughtful gift and a satisfying weekend project. In dry indoor air or a bright spot, expect the ball to need water more often than a pot would. If you love the idea of a small living sculpture and want a bigger challenge later, read thinking about purchasing your first bonsai.

Q: How does Grove handle kokedama?

Need to Know: Grove lists kokedama as its own growing method, so watering and feeding follow a moss ball. When a watering task appears, it is a check. Grove builds a care plan from the species, how you grow the plant, and whether it lives indoors or outdoors. Kokedama is one of the methods you can pick. The method changes watering technique and how often you water, feeding, pruning, repotting and the task rhythm. A watering task only shows up when it belongs on today's list, and then it asks one thing: does this plant need water today. You can edit the plan whenever you like.

A kokedama is a plant growing in a ball of soil wrapped in moss and string, and it turns an ordinary houseplant into a small living sculpture. Moss balls dry faster than pots, so the care comes down to one easy check: lift the ball and feel its weight. This guide covers good plants for a first ball, what you need to make one, and how to water, feed and refresh the ball.
