How to Grow and Care for Ivy in Water
Learn the distinct methods for growing ivy in water, whether for propagating new plants or for its long-term care as a soil-free houseplant.
Ivy is a resilient vining plant, admired for its lush, trailing foliage and its ability to thrive in indoor settings. A notable characteristic is its ability to grow and flourish directly in water. This method of cultivation is an alternative to traditional soil potting for decorative purposes.
Propagating Ivy in Water
To begin propagating ivy, select a healthy, vigorous vine from a mature plant that is free of pests or diseases. Using a clean, sharp knife or pruning shears, make a cut about four to six inches from the tip. The cut should be made just below a leaf node, the small bump where leaves and aerial roots emerge.
Once the cutting is separated, remove the leaves from the lower half of the stem. This step is important because any leaves submerged in water will rot, which can introduce bacteria. Ensure at least two or three leaves remain on the top portion of the cutting to facilitate photosynthesis.
Place the prepared cutting into a clear glass or jar with room-temperature water. A transparent container is advantageous as it allows you to monitor root growth and water clarity. Make sure the exposed nodes on the stem are submerged while the remaining leaves stay above the waterline. Place the vessel in bright, indirect sunlight, as direct sun can encourage algae growth. You should see roots developing within a few weeks.
Long-Term Ivy Care in Water
For those who wish to grow ivy in water indefinitely, the choice of container can influence the plant’s health. While a clear glass vessel is excellent for observing the root system, an opaque container can help slow the growth of algae by blocking light. This reduces the frequency of cleaning required.
To sustain an ivy plant in water, regularly change the water about once a week to replenish oxygen and prevent it from becoming stagnant. Stagnant water can lead to bacterial growth and potential root rot. Rinsing the roots under lukewarm water during these changes also helps remove any buildup.
Long-term water cultivation requires supplemental nutrition, since water does not contain the nutrients found in soil. You will need to add a balanced liquid fertilizer, diluted to about half-strength, to the water once a month during the spring and summer growing seasons. This provides the sustenance needed for continued growth.
Watering Ivy in Soil
When ivy is planted in soil, its watering needs are different from its water-grown counterparts. The “soak and dry” approach is effective. This involves watering the plant thoroughly, then allowing the top layer of soil to dry out before watering again. To check for dryness, insert your finger about an inch into the soil.
Proper drainage is a factor in maintaining a healthy potted ivy. The container must have drainage holes to allow excess water to escape. Allowing an ivy plant to sit in soggy soil can lead to root rot. After watering, it is good practice to empty any water that has collected in the saucer beneath the pot.
Observing the plant’s leaves can provide indications of its watering status. Yellowing leaves can be a sign of overwatering. Conversely, if you notice the leaves are drooping, dry, or crispy to the touch, the plant is likely underwatered. Paying attention to these signs allows for adjustments in your watering routine.
