What Type Of Orchid Fertilizers Should I Get?

It’s best to think of orchid fertilizers as vitamins for your flowers. They contain the necessary ingredients to maintain the orchids in good condition.

Plants use photosynthesis to create the needed food. One example of this is which is derived from oxygen.

This means that through the process of photosynthesis, the plant receives the necessary food but not the nutrients it needs to flourish – that’s why you need fertilizer.

Furthermore, the best fertilizers contain nitrogen, phosphorus and potassium which help with stem growth, healthy roots and strength.

When it comes to orchids, the most important thing to look for is nitrogen contents i.e. the maximum is 30 % – have in mind that more doesn’t mean better.

How to Fertilize the Orchids?

The manner of application depends on the type of fertilizer you’re going to use and the safest way is to always follow the instruction manual provided on the product.

Spray fertilizers are gentle and can be used on the entire plant except for the blooms while concentrated formulas are usually applied in the soil and root and can be either granulated or in a liquid form.

Some fertilizers come in the form of sticks and are usually slow-release formulas that are applied in the soil close to the roots.

How Often Should I Fertilize?

First thing first! When it comes to fertilizing orchids you must be careful not to overfeed them. Too much fertilizer can cause the orchid to get sick and wither and that’s why you have to follow a smart schedule for proper use.

Using a fertilizer that’s specially formulated for orchids helps because you have all the needed information on the product’s packaging, so just make sure you follow it.

Some fertilizers can be applied weekly, some over a few weeks and others require just a couple of days between applications.

Nevertheless, if it’s your first time applying orchid fertilizer start with a concentrated option that you can dilute since you can always dilute it more than prescribed to be on the safe side.

If you notice salt buildup in the container, you’ll know that you’ve used too much fertilizer. The salt can be harmful to the plant thus if this happens make sure you repot the orchid immediately.

When’s The Best Time to Fertilize?

The fertilizing time depends on the orchid and its blooming cycle. Some orchids flourish during the spring and summer months while others are winter bloomers. Some bloom even twice a year so you’ll have to adjust the fertilizing timing based on this.

During the growing period, you can add fertilizer weekly, three weeks in a row and then take one week off to allow the plant to prepare for sprouting. Make sure you don’t underwater the plants.

On the other hand, if you use a spray or stick fertilizer try to follow the package instructions in terms of the fertilizer application but stick to a schedule.

Once the orchid has bloomed, there’s a period of wilting and that’s when the plant enters the dormant phase.

When in this phase, the flower doesn’t require too much fertilizer so every other week will do to keep the plant strong until next season.

Try to water your plants in the morning since the leaves will have time to dry out in sunlight.

Last but not least, when the orchids are blooming they don’t require fertilizer because there’s no process of growth happening. This means you can add fertilizer once or twice a month.
