Do I need rooting hormone?
Not always. Easy-to-root plants like pothos, philodendron, and tradescantia root readily without any help. Rooting hormone is most beneficial for woody plants, succulents, and species that are notoriously slow to root. It can increase success rates and speed up rooting for challenging plants.
How long should roots be before potting?
For water-propagated cuttings, wait until roots are at least 2-3 inches long, ideally 3-4 inches. Longer roots give the cutting a better chance of surviving the transition to soil. You should also see multiple root branches, not just a single strand.
Can I propagate in winter?
Yes, but expect slower results. Most houseplants grow slowly or go dormant in winter, so rooting takes longer. If possible, wait until spring when plants naturally want to grow. If you must propagate in winter, provide supplemental light and warmth.
Why are my water roots different from soil roots?
Water roots and soil roots are structurally different. Water roots are adapted to absorb oxygen from water, while soil roots are designed to navigate through soil particles. When transitioning a water-rooted cutting to soil, keep the soil consistently moist for 2 weeks to allow the roots to adapt.
Can I put multiple cuttings in one container?
Yes, but with some caveats. For water propagation, multiple cuttings in one container is fine as long as they don't crowd each other. For soil propagation, you can plant multiple cuttings in one pot to create a fuller plant. Just ensure each cutting has enough space for root development.
How do I know if a cutting has failed?
Signs of failure include: mushy, brown stems (rot), completely yellowed or brown leaves, no growth after 6-8 weeks in good conditions, or a foul smell. If the stem is still firm and green at the node, there's still hope - be patient.
Should I fertilize cuttings?
No. Cuttings don't need fertilizer until they've developed a substantial root system and are actively growing new leaves. Fertilizing too early can burn developing roots. Wait at least a month after potting before introducing diluted fertilizer.
