Topping is best done during the vegetative stage of a plant's growth, specifically when the plant has developed six or seven leaf nodes along a sturdy stem.
Understanding Topping Timing
Topping is a pruning technique used to manage plant shape and encourage bushier growth. According to horticultural practices, the ideal window for performing this technique is tied directly to the plant's development phase.
The Vegetative Stage Connection
The reference states that topping coincides with the vegetative stage. This is the period when young plants are focusing their energy on growing leaves and stems aggressively, rather than flowering or fruiting.
The Key Indicator: Leaf Nodes
The most specific timing cue provided is the number of leaf nodes. Growers typically wait:
- Until the plant has six or seven leaf nodes.
- Ensure the plant has a sturdy stem at this point.
Waiting for this level of development ensures the plant is strong enough to handle the stress of being pruned and has sufficient foliage to continue growth effectively after the tip is removed.
What Happens During Topping?
Once the plant reaches the recommended six or seven nodes, the process involves:
- Pruning the central growing stalk.
- Removing the entire central growing tip.
This action redirects the plant's energy from growing taller to developing lateral branches, leading to a more compact and productive structure.
By following the guidance of waiting for the plant to establish six or seven leaf nodes on a sturdy stem during its vegetative phase, growers can effectively time the topping process for optimal results.
