Insufficient Light Intensity

Kalanchoe blossfeldiana is a high-light plant; if light levels are too low, the stems undergo etiolation, stretching toward the nearest light source to maximize photosynthesis.

Very Common

How to confirm: Observe if the internodes (space between leaves) are unusually long and if the leaves appear smaller than usual.

1 Move your Kalanchoe to a location with much higher light intensity, such as a bright south-facing window, to stop stems from stretching.

2 Supplement with a full-spectrum LED grow light to provide the necessary intensity for compact, healthy growth.

Excessive Nitrogen Fertilization

High levels of nitrogen promote rapid, succulent vegetative growth which can result in weak, elongated stems that lack the structural integrity to hold the 'Don Amador' blooms upright.

Common

How to confirm: Check if you have recently applied a fertilizer with a high first number (N) in the N-P-K ratio.

1 Stop all nitrogen-rich fertilization immediately to prevent further rapid, weak growth.

2 Prune the elongated, leggy stems back to a stronger node to encourage bushier, more compact growth.

3 Increase light exposure using a full-spectrum grow light to strengthen stem structure and support bloom development.

Improper Watering Frequency

Inconsistent moisture cycles can cause periods of rapid growth followed by stress, leading to uneven cell elongation and weak stem development.

Common

1 Monitor soil moisture levels closely using a moisture meter to ensure you only water when the top inch of soil is dry, preventing the stress of inconsistent cycles.
