When Is It Inappropriate To Fertilize Orchids?

Fertilizer plays a crucial role in plant growth, flower development, and root development. The ratio of nutrients in the fertilizer determines what factors it will contribute most to. Over-fertilizing orchids can lead to dry leaf tips and burned root tips, while unfertilized orchids are smaller and have fewer flowers.

To properly fertilize orchids, it is essential to use a balanced fertilizer that is diluted to half strength. Fertilize orchids once a month during the growing season, typically from spring to fall, and cut back to every two to four months during winter. It is important not to fertilize dry orchids, as they do not grow new roots or leaves. When planning watering, try to time the watering to be just before feeding. Proper fertilization will help your orchid develop a strong root system, healthy foliage, and gorgeous flowers.

A general rule for fertilizing orchids is to fertilize every 2 weeks during peak growth (spring and summer) and once a month during dormancy (fall and winter). Use a 30-10-10 fertilizer or orchid food, diluted to half strength.

The best time to fertilize orchids is during their active growth phase, which typically happens after they produce new leaves and roots. Most cultivated orchids grow in tropical or subtropical climates with a wet season and a dry season. Fertilize during the wet season when the orchids grow vigorously, and during the dry season when the orchid does not grow new roots or leaves.

It is recommended to stop fertilizing when the orchid starts its blooming phase or when it has undergone a shock such as a transplantation. As a general rule, fertilize orchids every 2 weeks during peak growth (spring and summer) and once a month during dormancy (fall and winter). Fertilize once the last bloom has fallen off the orchid, and aim to fertilize at least once a month and at most every other week.

How does Epsom salt help orchids?

Epsom salts are essential minerals for plants, aiding in water retention and supporting chlorophyll production and flowering. They also aid in plant defenses and protein production. Plants grown without media or with little media, like greenhouse Vanda, may dry out and wrinkle over time due to a lack of salts or electrolytes. To restore the plant’s plump state, an Epsom salt soak for an hour each day for three days or more is recommended.

Alternatively, for severe root rot, new root growth can be encouraged by an Epsom salt soak. Mix 1 tbsp/gal of water and ensure half of the plant, media, and all, soak for one hour each day. Rinse with water after use.

What is the best fertilizer for orchids?

The NYBG Senior Curator of Orchids recommends using a balanced fertilizer like 20-20-20 in powder form to provide all the primary nutrients needed for flowering plants. These nutrients include nitrogen (N), phosphorus (P), potassium (K), secondary nutrients, and trace nutrients. Nitrogen aids in vigorous growth and dark green color, while phosphorus promotes root development and flowering. Potassium is essential for overall hardiness and disease resistance.

Some orchid growers use high-nitrogen fertilizers like 30-10-10 to grow more leaves before switching to a balanced formula. However, it is important to remember to change over well before the spring bloom period for optimal results.

Is Miracle-Gro bad for orchids?

KC advises against using “regular” Miracle-Gro fertilizer for orchids due to the lack of instructions on the package. Instead, use “Miracle-Gro Orchid Food”, which is specifically designed for acid-loving plants. The difference is that regular Miracle-Gro fertilizers are typically more diluted and weaker, as most orchids are native to nutrient-poor environments, such as trees, and suffer from excess fertilizer.

Excessive fertilizer is common for other plants native to nutrient-poor environments, such as cacti or certain Australian plants. Therefore, it is recommended to use “Miracle-Gro Orchid Food” instead.

Should orchids be fertilized when in bloom?

Orchids require regular feeding during their active growth seasons and slightly starved during their dormant periods. Some orchids grow constantly and should be fed lightly year-round. High-quality fertilizer and water are crucial for orchid growth. The quality of water matters more than the fertilizer brand. Tap water is not suitable for mixing fertilizer, and softened water may contain ionized sodium. Distilled water is the best choice, free of chlorine, fluoride, and minerals, while rainwater is a strong second choice.

Do orchids like coffee grounds for fertilizer?

While coffee grounds are beneficial as a compost addition, their decomposition is not effective for most orchids. Furthermore, the rapid decomposition of orchid potting bark caused by coffee grounds results in root rot. It is therefore recommended that these grounds be reserved for use with other plants.

Are used coffee grounds good for orchids?

Coffee grounds are not a good source of nutrients for orchids due to their soil type. Terrestrial orchids can make the nutrients bioavailable to the plant, but adding coffee grounds to orchid potting mix can be detrimental to other orchid types. Coffee grounds break down through nitrifying bacteria within the soil, releasing natural plant fuels. However, epiphytic orchids are not planted in standard soil, and they have specific needs for potting medium. Therefore, adding coffee grounds to orchid potting mix can be detrimental to the plant’s health.

When not to fertilize an orchid?

Cultivated orchids typically grow in tropical or subtropical climates with a wet and dry season. During the wet season, orchids produce new growth, necessitating fertilization. During the dry season, they do not grow new roots or leaves, requiring no fertilization. Recognizing active growth and dormancy is crucial for proper orchid care. Some orchids, like Maxillaria tenuifolia, require regular fertilization throughout the year, while Coelogyne orchids go dormant during winter and require no fertilizer until spring.

Orchids respond to fertilization needs and dormancy, with new growth indicating hunger and no growth indicating rest. Observant orchid caretakers can read these signs and know when to feed or not. Fertilizing orchids is essential for overall health, but it must be done correctly.

What month do you fertilize orchids?

During active growth periods, such as warmer summer months and rainy seasons, it is essential to fertilize orchids with the right amount of fertilizer to ensure healthy development. However, as winter approaches, it is crucial to minimize watering and fertilizing based on growth. Some exceptions include Oncidiums, which start producing new growths in winter and can be continued fertilizing. However, a significant portion of the collection will be done with the growth period and remain dormant, conserving energy for the spring bloom period.

Watering and fertilizing should be sparingly applied, allowing the orchids to rest in a near-dry condition. It is important to note that shrivelled pseudobulbs are part of their cycle, even in the wild. Once temperatures return to normal, new growths such as sheaths, spikes, shoots, and roots will emerge.

It is also advised to avoid fertilizing orchids when they are sick or have experienced a shock, such as transplantation shock or sudden changes in the environment. Gradually, fertilizing the orchid with low concentrations when it shows signs of recovery and growth can help restore normal levels.

Is Epsom salt good for orchids?

Plants grown with little media or without media, such as greenhouse Vanda, may dry out and wrinkle without regular watering. This is due to the loss of salts or electrolytes over time. To restore the plant’s plump state, an Epsom salt soak for an hour each day for three days can be helpful. If a plant has severe root rot, new root growth can be encouraged by soaking half of the plant, media, and all, for one hour each day. Rinse the plant with water after each soak.

How often should I water an orchid?

Watering your orchid every 7 to 11 days, especially when the mix is dry, is essential to prevent damage and prevent overwatering, which can lead to crown rot, root rot, and other infestations. Watering in the morning is recommended as nighttime watering can leave water sitting for a period. Additionally, consider the temperature of your house, as high thermostats may cause the orchid to grow in summer.

Do coffee grounds help orchids?

Coffee grounds can provide nutrient benefits to orchids, but their consistency can hinder their drainage, potentially causing negative effects. Carefully and sparingly use coffee grounds on orchids, ensuring proper drainage. Other kitchen waste, such as orange and banana peels, can also be beneficial for plants.
