The pussy willow, most often the North American native Salix discolor, is a rewarding shrub to multiply at home due to its vigorous growth habit. This plant possesses a natural abundance of auxin, a plant hormone that stimulates root development, making it one of the easiest species to propagate from cuttings. Because of this inherent rooting compound, gardeners can successfully create new plants without needing commercial rooting hormones or complex equipment. This guide provides a straightforward method for multiplying your pussy willow stock using the simple water rooting technique.
Timing and Selection of Cuttings
The most successful cuttings are taken when the plant is dormant, typically from late fall after the leaves drop through late winter, just before the buds begin to swell in early spring. Taking cuttings during this period ensures the plant’s energy reserves are concentrated in the stem rather than being diverted to leaf production. This material is known as hardwood, referring to mature, lignified stems from the previous year’s growth.
The ideal cutting should be approximately the thickness of a standard pencil and between 6 to 12 inches in length. Using clean, sharp pruning shears, make a diagonal cut just below a node, which is a slightly swollen area where a leaf or bud was previously attached. This diagonal cut maximizes the surface area for water absorption and root emergence.
Make the top cut above a node to distinguish the top from the bottom of the cutting, as roots will only form from the end closest to the original plant base. Selecting a branch that is straight and healthy, free from any signs of disease or damage, will increase your propagation success rate.
Step-by-Step Water Rooting Method
Once your cuttings are prepared, the simple process of water rooting can begin. First, remove any remaining buds or side shoots from the lower half of the cutting to prevent them from rotting once submerged in water. This preparation ensures that the cutting’s energy is directed toward forming new roots rather than trying to sustain foliage.
Place the prepared cuttings into a clean, clear glass jar or vase, ensuring that at least one or two nodes remain submerged in the water. Using a clear container allows you to easily monitor the progress of root development and observe the water quality. The cuttings should be situated in a location that receives bright, indirect sunlight, such as an east-facing window, avoiding intense afternoon sun that can overheat the water.
Change the water every three to five days, or whenever it appears cloudy, to replenish the oxygen supply and prevent the buildup of anaerobic bacteria. This regular refreshment mimics the flow of fresh water the willow would naturally seek in its native, moist habitat. Within two to four weeks, you should begin to see small, white, fibrous roots emerging from the submerged nodes.
Allow the roots to develop to a length of at least three to four inches before attempting to transplant. This gives them a better chance of surviving the transition to soil. Since the newly formed root structures are delicate, waiting until they are more robust will prevent breakage during the planting process.
Transplanting Rooted Cuttings
The transition from water to soil requires careful handling to ensure the fragile new roots establish themselves without shock. When the white, fibrous roots are sufficiently developed, gently move the cutting from the water vessel to a prepared planting site. The pussy willow thrives in full sun to partial shade and prefers consistently moist soil, reflecting its preference for wetland-like conditions.
When choosing a permanent location, remember that willow roots are aggressive water-seekers, so avoid planting near underground water lines, septic systems, or building foundations. Dig a planting hole that is wide enough to accommodate the spread of the new roots without bending or breaking them. The cutting should be planted at the same depth it was submerged in the water, with the original soil line matching the surrounding ground level.
Carefully backfill the hole with soil, gently firming it around the roots to remove any large air pockets. Immediately after planting, thoroughly saturate the soil with water to settle it and provide the initial moisture the new plant needs. During the first growing season, maintain consistent soil moisture for the cutting’s successful establishment. Also, provide temporary shelter from strong winds or extreme heat until the plant is visibly growing new foliage.
