When Should You Replace a Mother Plant?
Most cannabis mother plants noticeably lose vitality after 6 to 12 months. Typical signs that it’s time to replace her include:
- Woody, hard-to-cut stems
- Slower growth and smaller shoots
- Discoloration, pests, or disease symptoms
- Declining cloning success rate
Preparing the Mother for Cloning
Before taking cuttings, prep your plant by reducing nitrogen intake about a week in advance and using clean, sharp tools. This increases your chances of getting strong, healthy clones.
Choosing the Best Clone to Replace the Mother
Take several cuttings and choose the strongest and healthiest to become your new mother. Look for the following traits:
- At least 3–5 nodes
- No signs of pests or mold
- Upright growth and vibrant green color
