Low Humidity / Dry Air

Kalanchoe tomentosa is a succulent that prefers moderate humidity; extremely dry indoor air can cause the moisture at the leaf margins to evaporate faster than the plant can replace it.

Very Common

How to confirm: Check if your indoor environment is near a heater or air conditioner vent which accelerates transpiration.

1 Increase local humidity around the plant by using a pebble tray or a humidifier to prevent further moisture loss from leaf margins.
2 Mist the foliage occasionally with a fine spray to provide immediate surface hydration.
3 Monitor soil moisture levels closely to ensure the plant is not also experiencing drought stress, using a moisture meter for accuracy.

Salt Accumulation from Fertilization

Excessive buildup of mineral salts from tap water or fertilizer in the substrate can cause osmotic stress, leading to localized tissue death at the leaf tips.

Very Common

How to confirm: Look for a white, crusty residue on the soil surface or the rim of the pot.

1 Flush the substrate thoroughly with distilled or demineralized water to leach out accumulated mineral salts from the soil.
2 Repot the plant in fresh, well-draining potting mix to provide a clean environment free of salt buildup.
3 Use a moisture meter to monitor watering frequency and prevent future over-fertilization or salt-heavy waterings.
warning

Underwatering

While drought-tolerant, prolonged periods without water cause the succulent to prioritize moisture for the core, leading to desiccation and browning of the furthest extremities (the tips).

Common

How to confirm: Check if the soil is pulled away from the edges of the pot and feels bone dry several inches deep.

1 Check the soil moisture level immediately using a moisture meter to confirm if the root zone is completely dry.
2 Thoroughly soak the soil until water drains from the bottom of the pot, ensuring the entire root ball is rehydrated.
3 Trim away the dead, brown tips with sterilized shears to prevent further aesthetic decline and monitor for new growth.
warning

Edema (Cellular Rupture)

Fluctuating water availability causes cells to take up too much water, eventually bursting and leaving behind necrotic brown spots or tips.

Common

How to confirm: Observe if the brown areas appear slightly raised or accompanied by small bumps on the leaf surface.

1 Stabilize the watering schedule to prevent rapid fluctuations in soil moisture, ensuring the soil dries out slightly between waterings.
2 Ensure the plant is in a pot with excellent drainage and use a well-aerating medium like a mix containing perlite to prevent waterlogging.
3 Monitor soil moisture levels closely with a meter to ensure you are watering only when the top inch of soil is dry.
