How Often Should Wintertime Houseplants Be Fertilized?

Most plants do not require fertilizer in winter, as they are not growing as actively. However, some plants may need to be fed during this time, and the frequency depends on the type of plant. It is best to avoid fertilizing houseplants in winter, as it can cause more harm than good.

The timing of fertilization depends on the type of plant, with some plants needing more than others. As a general rule, it is best to adjust your watering routine and stop fertilizing in fall. Indoor plants generally do not need fertilizer in winter because they are not growing as actively. Feeding them now will upset their natural cycle, so stop feeding until early spring.

During the growing season (April-October), it is recommended to fertilize houseplants every two weeks. However, depending on the chosen fertiliser, you might feed quarter to half-strength in winter, every time you water, or at the same dose all year round because it is not recommended. Most common houseplants do well with a quarterly seasonal application of fertilizer. In warm climates, it is recommended to fertilize houseplants year-round every 4 to 6 weeks.

In the sunny Caribbean, house plants do need fertilizer during the winter months, as while roots are expanding, there is a high need for extra nutrients. Fertilization is generally not necessary during the winter months as most houseplants are not growing as actively.

How do I know if my plants need more fertilizer?

Light green foliage, yellowing mature foliage, chlorosis, and purple leaves indicate a plant’s need for nitrogen, potassium, or phosphorous. If none of these signs match, a soil test can help determine if the plant needs these nutrients. If unsure, consult a garden center professional for guidance on selecting the best fertilizer for your soil and plants. Remember, the goal is to ensure the health and growth of your plants.

How to tell if a plant is over fertilized?

Over-fertilization in commercial pot or container-grown crops can lead to symptoms such as crusting on soil, yellowing and wilting lower leaves, browning leaf tips and margins, blackened or broiled roots, defoliation, slow or no growth, and even seedling death. This is due to high concentrations of soluble salts in the potting medium, which damage roots and predispose plants to certain root diseases.

What is the best natural fertilizer for indoor plants?

Compost tea is a nutrient-rich solution made by steeping compost in water. It provides plants with a balanced range of essential nutrients. To make it, fill a bucket with water, let it sit for 24 hours, and add compost to a burlap sack or old pillowcase. Steep for 24-48 hours, stirring occasionally. Dilute the compost tea with water at a 1:10 ratio and use it every 4-6 weeks, as it’s gentle enough to avoid nutrient burn.

How often do I need to fertilize my indoor plants?

Fertilizing houseplants is essential during spring and summer, and can be done using liquid, crystalline, granular, spike, and tablet forms. Use fertilizers specifically formulated for houseplants or general complete and balanced fertilizers. Mix them at half or quarter the strength outlined in the instructions, as houseplants grow slower than outdoor plants. The frequency of application depends on the product and varies from every 2 weeks to once every 3 to 4 months. Fertilize only when houseplants are actively growing, as they often have a period of rest during winter, so no fertilizer is needed.

Do you put fertilizer on top of soil?

The application of fertilizer is typically conducted during the planting process, with the substance placed at a depth of between one and two inches beneath the soil surface, in close proximity to the seed row. In regions with cooler temperatures and higher precipitation levels, a “starter application” is placed in a subsurface band to enhance seedling growth. The application of fertilizer in a band enhances seedling growth and reduces susceptibility to pests and diseases. To prevent injury, it is inadvisable to apply high nitrogen rates in close proximity to seeds.

Can you fertilize houseplants too much?

Fertilizing houseplants sparingly during the growing season, from early spring to late summer, is recommended to prevent damage to plants. Plants benefit most from fresh nutrients during this time. Fertilization can be bi-weekly or monthly, depending on the fertilizer used. It is important to read the label provided for dilution and timeline recommendations. Recently potted or repotted plants do not benefit from fertilizer, as their fresh potting mix contains nutrients they have not yet used.

To avoid damaging recently repotted plants, wait 2-3 months after repotting before fertilizing. If repotted during fall and winter, fertilizer can be forgone until the next growing season. Fertilizer is not necessary for plants in low-light environments due to slower metabolic activity.

What time of day is best to fertilize potted plants?

Plants only uptake water at night, not nutrients. If you must feed plants, only do so in the morning. Foliar fertilizing in the evening can be helpful, but morning fertilizing is also beneficial. Bird sanctuaries advise against feeding birds, as it is not good for them and all plant life. Feeding foods like bread to birds can cause problems, but even bird feeders have downsides. In a garden, especially a vegetable garden, growing food plants on degraded soils can lead to pests. To achieve pest-free and nutrient-dense food, supplementing nutrients, organic matter, microorganisms, and water can help. It is essential to avoid feeding birds and plant life in bird sanctuaries.

Should I fertilize houseplants in the winter?

The winter season is not typically conducive to fertilization, as houseplants are not actively growing. However, indoor gardeners should implement a regular fertilization regimen in the spring and summer, when plants are undergoing active growth.

Do houseplants go dormant in winter?

Plants often experience periods of dormancy during the winter, which is essential for their survival. Symptoms of dormancy include wilting, dropping leaves, and appearing dead. However, some plants may not produce new growth during this period. Dormancy can be triggered by seasonal changes or environmental stress. Colder weather signals plants to go into dormancy before winter arrives, while environmental stress like lack of water, cold temperatures, or nutrients can also cause plants to conserve energy for future growth. Understanding whether plants are dormant or dying can be challenging due to similar symptoms.

Should I mist my plants daily?

Misting plants depends on the season and air quality in your space. It’s recommended to mist a few times a week, but daily if possible. If you live in an arid climate with high climate control, misting should be more frequent. If your climate is more humid and you don’t constantly run the heat or air conditioner, misting once or twice a week might be sufficient. Experiment with frequency to find the best schedule for your plants. It’s crucial to mist the right parts of the plant to ensure water absorption.

What happens if you don’t fertilize plants?

Fertilizing plants is crucial for their growth and health, as they require essential nutrients like nitrogen, phosphorous, and potassium. These macronutrients are essential for plants to thrive and maintain their health. Without enough of these nutrients, plants may have weak stems, smaller leaves, fewer flowers, and poor color. Fertilizer can correct most nutrient deficiencies by adding it to the soil. The best fertilizers for plants depend on whether they are growing in your garden or in containers.

It is essential to remember that plants require nutrients beyond sunlight and water, and without them, they may suffer from health issues. Therefore, it is essential to regularly replenish the supply of these nutrients to ensure the health and growth of your plants.
