How to buy the right Orchids?

Buying an orchid is easy. It’s just like buying another plant. You can pick one up from specialty growers and websites.

Before purchasing one either from websites or specialty Orchid growers, you should take little steps to make sure you get a healthy plant possible. Those plants can survive their first bloom and rebloom again.

Start with a healthy Orchid

1. The roots

The first thing you have to know is that Orchid is not planted in soil. Orchids are categorized as Epiphytes. This means that they do not grow on the ground, but they grow in the air. Orchid grows on the surface of a plant and derives its moisture and nutrients from the air, rain, and water.

Roots are set in a blend of bark and other large organic material and placed in a pot. If the root is wet they are dark green, If they are dry they are light green. The root is thick and likes succulent.

Roots that are in light green and dark green color means the Orchid has a healthy root. Avoid picking Orchids with brown, white, or shriveled roots. These are absolutely not healthy Orchid plants.

2. Leaves and stems

If you have different Orchid varieties, they have leaf shapes and textures that are different. Healthy orchids show green color leaves and stems.

Unhealthy Orchid has yellow marks or dark blemishes. Stems should be upright and arching.

3. Bulbs

There are two most common varieties of Orchids. The first is the one that grows from one single growing point or called monopodial. The second is the variety that creeps rhizome or called sympodial.

Sympodial Orchids send up a fresh bulb. It comes with new blooms and leaves every year. Good Sympodial Orchids should pseudobulbs that are fat and plump.

4. Potting

You must inspect how the Orchid that you are going to select is potted. Make sure that you select the one that has good airflow and aerated properly. 

Make sure it is not potted in the material that is too soggy or too dry. Wet and dry material can cause a decline in the health of this plant.

5. Diseases and other sign of distress

Inspect carefully Orchids by checking them from head to toe. Leaves should be vibrant and succulent.

Unhealthy Orchids have symptoms of insect and disease including discoloration (yellowing or browning), yellow, brown spots, or yellow spots, wet spots or areas, limp or soft leaves, unnatural torn leaves, webbing means it has been infested by Spider mites, and rotting roots.

Other consideration

1. Mature plant

Select a mature plant because younger plants are fussier. Young plants or seedlings would take you many years to care for before they bloom.

If you are a beginner and want to have a faster bloom result, it could be disappointing. To avoid this, select a mature plant that has one flower bloom and some buds. 

2. Avoid Orchid with old bloom

Do not select plants with yellowing blooms because of it the end of its blooming. It will be falling off soon. If you select an Orchid plant with some unopened buds, you need to wait one month or even longer to show off your Orchids.

3. Opened bloom

If your purpose of buying an Orchid plant is to have a long-lasting plant, avoid selecting the plant that its blooms already opened. You should select the unopened bloom for enjoying the show for longer.

Where to buy orchid?

Orchids are expensive compared to other ornamental plants. So before you throw away your money for the wrong decision, it is essential to make the best choices when shopping for orchids.

1. Nursery

If you are lucky, you might find Orchid nurseries in your city. You can select from so many options of sellers. The nursery is where they are hosting different Orchid plant sellers.

If you are a beginner, you really need expert and reliable advice. That is why an established nursery is a right place to go.

You can ask many questions, and they can answer because they know well. They also offer a big selection of exotic and unusual varieties.

2. Stores

You can pick Orchid from box stores, groceries, and plant stalls nearby. They usually offer highly tempting by displaying huge blooms.

But you must be careful and find a healthy plant. Because they tend to be less in taking care of their Orchid plants, and they might not have expertise in orchid care.

Ask if the plant is fresh and new. New plant to be relatively healthy. Do not buy when it comes to huge discounted prices. It could be a bad gamble.

3. Expert

You can always find Orchid lovers and experts in nurseries or high-end florists. They know what to do and what to explain about the plant. They know the value of their stock.

You get proper guidance and instruction in Orchid care from them. If you come back for further purchases, it would be to your advantage.


When to fertilizer Orchids? How Often to Fertilize Orchids?

1. Feed weekly and feed weakly

Orchids only can be fertilized one time in one month. To fertilize Orchids can be done on a weekly basis too but use only a weak concentration of nutrients (feed weekly and feed weakly). Fertilizing less with higher concentration is not recommended.

2. Feed during the growing season

Orchids are in a dormant state in the winter months. Orchids slow down in growth in winter and do not feed them. You can feed them again when spring comes.

A higher percentage of nitrogen can be applied during the growing time. The best time to fertilize Orchid is during the Summer and Spring months.

3. Do not feed an unhealthy Orchid

If Orchids are unhealthy and weak, do not feed them. Do not overfeed Orchids. Notice if leaves are floppy and dark green, they are unhealthy.  

Too many fertilizers will force orchids to grow too fast and harm them. It becomes weaker and becomes susceptible to Orchid diseases. They will not be looking at their best at this stage.


How to fertilize Orchid?

Orchids need only less amount of fertilizer than other plants. Orchids also only need less watering, the less even better.

Orchids can still live even if you overfeed them and adding more fertilizer nutrients. But if it is too much you can harm them. You have to know the right amount at the right time. It would be the key to beautiful blooms and stronger Orchid plants.

To fertilize Orchid, just look for NPK tablets with a balanced formulation like 20-20-20 or 10-10-10. A safe application is to use the 20-20-20 NPK formulation.

Use the 20-20-20 NPK formulation fertilizer at its quarter strength. If you use a 10-10-10 NPK formulation fertilizer, use it at a rate of half the strength.

Orchids do not need a high concentration of Nitrogen. Nitrogen with more than 20% in a fertilizer formulation can become a pollutant and harm your Orchid.

Many years ago, Urea was thought to be the best fertilizer for Orchids. Today it is not true. Choose a fertilizer that contains no Urea at all.

Calcium and Magnesium are micronutrients that can be applied to orchids. Orchids need them and use calcium to build cell walls and other structures. Magnesium is used to make chlorophyll for metabolic processes. The right amount of Calcium and Magnesium for Orchids is 15% Calcium and 8% Magnesium.

Other elements like Iron, Copper, Zinc, and other micro-nutrients strengthen new stem and flower growth. Stems are ready to support the weight of multiple blooms so that they do not droop.


How to make Orchid bloom again?

To have an Orchid that after the first bloom would bloom again is to have a healthy Orchid. To make a healthy Orchid, the plant should receive stable, consistent, proper light, the right amount of water, and the right humidity. With regular feeding, Orchid should bloom again.

Cool temperatures at night between 52 and 58 degrees Fahrenheit (12 to 14 degrees Celcius) will change the Orchid’s chemistry. This will stimulate the plant to form flower spikes.


How to water an Orchid?

For beginners, it is not advisable to water your Orchid at home in your kitchen sinks. This is because you might soak water on delicate parts or uneven water can cause rot. Instead, let’s use the following method for beginners.

The first step is to get a container with water ready. Let the water sit for 24 hours (uncovered). The purpose is to eliminate harmful chemicals like chlorine in the water.

Pour the water onto your pot until the water reaches the rim. Let your Orchid plant soak for at least 10 to 15 minutes.

After 10 to 15 minutes, take out the Orchid pot and let it drain. The water must be drained completely. Drain any remaining water in your ceramic pot. Once dry enough, place them back in their pot.
