Can Orchids Be Treated With Osmocote?

The Osmocote Product Use Guide by The Scotts Company, LLC does not specifically recommend Osmocote for orchids, but it does claim that it works better with smaller soil particles than larger ones. The author has been using Osmocote plant food for their orchids for the past half a year and finds that it doesn’t do any harm.

The secret to success in growing orchids at home is the potting mix they are grown in and Osmocote Professional Orchid. Osmocote granules might wash out of coarse bark media, but if the mix is fine enough to retain it, this isn’t a problem. For orchids, use it at less than the suggested rate, probably 1/4 of what the label says, and don’t apply it in late fall or winter if your plants aren’t in active growth.

Osmocote is safe to use on new plants as it releases nutrients into the soil over time, so you don’t have to fertilize them as often. The author has used Osmocote on bark when they are summered outdoors and when away, and their empirical observation is that it doesn’t do any harm.

Pelleted slow release fertilizer is good for orchids or any plant potted plant, as it takes a while to get active. The controlled release of nutrients means it won’t burn soft leaves or tender young roots. The Osmocote Product Use Guide provides suggestions on how much and how often to use Osmocote on potted orchids, such as those in 6″ clay pots.

How often should I fertilize orchids?

Phalaenopsis orchids should be fertilized once every other week or at least once a month after their blooms have dropped. It is recommended not to fertilize during the orchid’s bloom. Instead, use a weak solution of a balanced plant fertilizer, diluting it to ¼ strength. To avoid overwatering, skip watering during the fertilization weeks. To fertilize, choose a fertilizer with equal amounts of nitrogen, phosphorus, and potassium (look for 20-20-20 on the label). Mix the weakened fertilizer with water, ensuring at least half of the solution is diluted.

Is Osmocote safe for orchids?

Can you use slow release fertilizer on orchids?

The author received a bottle of slow release fertilizer from an orchid seller, which consists of flat-colored green beads. They are curious about the safety and suitability of this fertilizer for sphagnum moss growing and bark mix growing. The directions recommend applying it once per 6 months for indoor use. The author plans to test the slow release beads for indoor use, using ice cubes instead of dilute fertilized water. They believe that ice cubes might stimulate the same effect as nighttime temperature drops outdoors. The author is currently testing the beads for indoor use, hoping to find a solution to the issue.

What should you not do with an orchid?

Orchids are the largest and most diverse flowering plant family, with over 880 genera and 22, 000 species. They are typically tropical plants, living as epiphytes or “air plants” hanging on trees for support. Some are lithophytes or “rock plants” growing on or among rocks, while the remaining orchids are terrestrials growing in the loamy detritus of the jungle floor.

To give general guidelines on orchid care, there are only several dozen species widely produced and even fewer available at local nursery. Hybrids, created by crossing different species and genera, are often sold at nurseries, florists, hardware chain stores, and groceries. These hybrids have desirable characteristics such as color, fragrance, flower size, and ease of care, outperforming the challenges of pure orchid species. Today’s orchid hybrids are rewarding house plants to grow and relatively easy to care for if understanding their basic needs is taken.

Can you over fertilize orchids?

The accumulation of salt in orchids can be attributed to the over-fertilization of the plant, which can result in the formation of a crust-like substance on the medium, pot, or substrate, exhibiting a whitish to brownish hue. This buildup can have detrimental effects on the plant’s health, particularly in sensitive genera such as Paphiopedilums, Phragmipediums, Pleurothallids, and Bulbophyllums, which may experience irreversible damage if left unchecked.

When should you not feed orchids?

The most prevalent methodology for fertilizing orchids is the application of a diluted solution of 1/2 to 1/4 strength on a weekly basis. In the fourth week, it is advisable to refrain from the use of fertilizer and to flush the potting media in order to eliminate any salt accumulation. This practice helps to maintain healthy growth and prevents the need for frequent watering.

When should you not fertilize orchids?

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.

Can I use Osmocote on all plants?

Osmocote is an inorganic fertilizer that offers the benefits of organic fertilizers. It is safe, clean, and smells good, making it suitable for most garden plants and lawns. Plants can only use inorganic nutrients, which are released over a longer and safer period of time. Organic fertilizers need to be broken down into inorganic nutrients before they can be used by the plant. Osmocote’s advantage over organic fertilizers is that the nutrients are already in an inorganic state, allowing the plant to start using it immediately. The coating of Osmocote is organic and based on soybean oil, making it the best of both worlds.

Is it OK to fertilize orchids while in bloom?

Fertilizing orchids is crucial during vegetative growth before flower buds appear, and can be withheld until the plant completes its next dormant cycle and begins its active growth cycle again. Experienced growers may use a “three weeks on, one week off” routine, fertilizing weakly for three weeks and taking a week off to flush out built-up salts. Orchids have slightly different fertilizing needs, with most alternating active growth periods, culminating in flower production, followed by a dormant period, corresponding to their native wet-dry season cycles.

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, phosphorus, and potassium, which help with vigorous growth, root development, flowering, and 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.

It’s important to remember to change over well before the spring bloom period. Chemical fertilizers contain salts that can build up over time, so rinse them out by occasionally watering with plain water.
