Kalanchoe Blossfeldiana

Determining the right time to water your florist kalanchoe is key to its health and flowering. To check if it's time, feel the soil moisture 1-2 inches deep; dry soil at this depth indicates it's time to water. Wilting leaves suggest the plant needs water, while yellowing or browning leaves signal dehydration. Assessing the weight of the pot can also help, as a lighter pot suggests the need for watering. Adequate water is necessary for flower production, with a decrease in flowers indicating insufficient watering. Be mindful of over-watering, especially in moist soil, as it can cause root rot, and avoid under-watering to prevent wilting and stunted growth. Lastly, adjust your watering schedule based on temperature, humidity, and seasonal changes to ensure the florist kalanchoe remains healthy and vibrant.

Fertilizing Florist kalanchoe helps provide nutrients to the growing medium. While this plant does store water and nutrients, adding plant food during the growing season promotes healthy growth. Fertilizing also helps mature specimens produce blooms in the growing season.

Florist Kalanchoe thrives in partial sunlight, requiring about 3-6 hours of sunlight daily. It can also tolerate full sunlight, especially in cooler weather, and even full shade conditions with above 6 hours of sunlight. However, the optimal condition is moderate sunlight exposure, as excessive exposure may lead to sunburn, while too little could stunt growth. It's important to watch how sunlight moves through your garden or indoor space to find the perfect balance for your Kalanchoe, ensuring it gets diffused light similar to its natural habitat.

Florist kalanchoe, also known as Kalanchoe blossfeldiana, thrives in temperatures between 20 to 27°C (68 to 81°F). It prefers these conditions for optimal growth but can tolerate a wide range of temperatures, from 10 to 38°C (50 to 100°F). During winter, which is its growing season, it's crucial to maintain temperatures above 10°C (50°F) for the healthiest growth. If temperatures fall below this threshold, moving the plant indoors to a well-lit area is advisable. Watering routines should be adjusted according to temperature changes, with increased watering in higher temperatures and reduced watering as temperatures approach 10°C (50°F). For outdoor overwintering, a sheltered spot with ample sunlight and possibly a temporary greenhouse can offer extra protection against consistent low temperatures, keeping the plant adequately moist.

Watering your florist kalanchoe properly involves several techniques to maintain optimal hydration without over-watering. Bottom-watering, where the plant pot is placed in a tray filled with water, allows roots to absorb moisture gradually and prevents foliage diseases. If you're using a watering can, choose one with a narrow spout for targeted watering at the soil level, avoiding the leaves. Employing a moisture meter can help in gauging the soil's moisture accurately to prevent over or under-watering. Always aim to keep the foliage dry to avoid fungal diseases. Observing the plant for signs of hydration, such as slightly wilting leaves, will help in determining the right amount of water. Adjust your watering habits based on these observations to ensure the florist kalanchoe stays healthy and hydrated.

Florist kalanchoe, like all plants, benefits from extra nutrients. However, it only requires a small amount of fertilizer during the growing season. It is recommended to fertilize it 1-2 times per year, specifically in the spring and autumn. Avoid fertilizing in the winter and summer when the plant is dormant. When it comes to repotted plants, be cautious and reduce the amount of fertilizer. It's also advisable to wait a couple of months after repotting before applying fertilizer.

Indoor plants, including Florist Kalanchoe, require adequate lighting for optimal growth, especially when natural sunlight is insufficient, such as in winter or less sunny spaces. Artificial lights, like LED lights, are beneficial as they can be customized to provide specific wavelengths of light needed by plants. Full sun plants need 30-50W/sq ft, partial sun plants 20-30W/sq ft, and full shade plants 10-20W/sq ft of artificial light. The light source should be placed 12-36 inches above the plant and turned on for 8-12 hours per day to mimic natural daylight hours, supporting faster and healthier growth.

If Florist kalanchoe is exposed to temperatures below its tolerance, visible signs such as water-soaked necrosis, wilting, and leaf fall might occur, especially after a mild frost. The best course of action is to trim off the frostbitten areas to prevent further damage. Moving the plant to a warmer indoor environment immediately or setting up a makeshift greenhouse can offer protection against the cold. When housed indoors, placing the plant near a south-facing window ensures it receives enough sunlight, which is crucial for its recovery and growth. Additionally, when using a greenhouse, proper ventilation is essential to prevent decay due to inadequate airflow.

The amount of water your florist kalanchoe requires can vary, but a good rule is to thoroughly saturate the soil until water runs out from the bottom for a standard 6-inch pot. This will need to be adjusted based on the size of the pot, root depth, and the plant's growth stage. Allow the top 1-2 inches of soil to dry out thoroughly before the next watering. Over-watering can cause root rot, and under-watering can lead to leaf drop and stunted growth. Signs of proper watering include lush, plump leaves and vibrant flowers. Adjust your watering amount to avoid overwatering signs, such as yellowing leaves or sogginess, and under-watering symptoms like wrinkled or shriveled leaves.

Florist kalanchoe, like other plants, goes through a dormancy phase where fertilizing should be avoided. During the summer and winter, the plant stops growing, so it's best to refrain from applying fertilizer. Additionally, it's recommended to not fertilize for the first few months after repotting in the spring.

Symptoms of insufficient sunlight in Florist Kalanchoe include leggy or sparse growth, which involves longer spaces between leaves or stems, making the plant appear weak. Insufficient light can also impact flowering and fruiting negatively, cause lighter-colored new leaves due to a lack of chlorophyll, and lead to smaller new leaves compared to older ones. Conditions such as chlorosis, where leaves turn yellow, sunscald that causes pale or necrotic spots, leaf curling as a defense against extreme sunlight, wilting from increased water loss, and leaf scorching characterized by brown, dry edges, may also occur under improper lighting conditions.

During the summer, it's important to keep Florist kalanchoe below its maximum tolerable temperature to prevent it from entering a dormant state and to protect it against rot in high humidity. If the plant experiences temperatures above its maximum tolerance, you should remove any dry or rotten parts to stop the spread of decay. Moving it to an area with partial shade can also help protect it from direct midday and afternoon sunlight. Additionally, pausing watering until the weather cools down can prevent further stress and damage to the plant.
