Characteristics of Tocho-eda:
Length: Significantly longer than regular branches, often exceeding the desired proportions of the bonsai.
Thickness: Thicker than regular branches, with a disproportionate diameter.
Internode length: Longer gaps between nodes (where leaves or branches emerge) compared to regular branches.
Vigor: Grow rapidly, often at the expense of other branches, weakening the overall structure of the bonsai.
Causes of Tocho-eda:
Overzealous fertilization: Excessive nutrient availability can stimulate rapid and uncontrolled growth, leading to tocho-eda.
Insufficient light: When light is inadequate, the tree may prioritize vertical growth towards a light source, resulting in tocho-eda.
Poor pruning: Improper or infrequent pruning can allow certain branches to grow unchecked, leading to tocho-eda.
Environmental stress: Factors like extreme temperatures, pests, or diseases can weaken the tree, causing it to produce tocho-eda as a survival mechanism.
Prevention and Management of Tocho-eda:
Balanced fertilization: Apply fertilizer cautiously, avoiding overfeeding and promoting balanced growth.
Adequate lighting: Provide sufficient sunlight or artificial lighting to meet the tree's needs and prevent lanky growth.
Regular pruning: Prune regularly to maintain the desired shape and size, removing tocho-eda as they emerge.
Address underlying issues: Address any underlying environmental or pest issues that may be causing stress and triggering tocho-eda growth.
