Should I root cuttings in water or soil?

Answered by Edward Huber

When it comes to rooting cuttings, there are a few options to consider – rooting in water or in soil. While some plants can successfully root in water, it is generally recommended to root cuttings in a soil-less potting mix for better results. Let’s explore the reasons behind this recommendation.

1. Root development: Rooting cuttings in a soil-less potting mix tends to result in a stronger and healthier root system compared to water rooting. When cuttings are placed in a potting mix, they have access to essential nutrients and beneficial microorganisms present in the soil, which can promote root growth. This can lead to a more robust and well-established plant in the long run.

2. Moisture control: Water rooting can sometimes lead to overhydration of the cuttings, as they are constantly submerged in water. This can increase the chances of rotting or fungal infections. On the other hand, a soil-less potting mix provides better drainage, allowing excess moisture to escape and reducing the risk of root rot. This is especially important for plants that are sensitive to waterlogged conditions.

3. Nutrient availability: While water can provide some level of moisture to the cuttings, it lacks the necessary nutrients for sustained growth. A soil-less potting mix, on the other hand, can be enriched with organic matter or added fertilizers to provide a nutrient-rich environment for the cuttings. This helps them establish roots and develop into healthy plants more efficiently.

4. Stability: Rooting cuttings in a soil-less potting mix can provide better stability compared to water rooting. As the roots start to develop and anchor themselves into the potting mix, the cuttings are less likely to be dislodged or disturbed. This stability is crucial for the successful establishment of new plants.

5. Adaptation to soil: Rooting cuttings directly in a soil-less potting mix allows them to acclimate to the soil conditions they will eventually be planted in. This can make the transition smoother when the cuttings are eventually transferred to their permanent growing location. Water rooting may not offer this advantage, potentially leading to shock or slower adaptation when the cuttings are transplanted.

In my personal experience, I have found that rooting cuttings in a soil-less potting mix has yielded better success rates and healthier plants compared to water rooting. The potting mix provides a more stable and nutrient-rich environment for the cuttings to establish roots and develop into thriving plants.

To summarize, while some plants can root in water, using a soil-less potting mix for rooting cuttings generally leads to better root development, moisture control, nutrient availability, stability, and adaptation to soil conditions. It is important to choose the appropriate method based on the specific needs of the plant you are propagating.
