How To Get Rid Of Scale On Orchids Successfully

There are four ways on how to get rid of scale on orchids. It’s crucial to learn about the solutions for common problems in orchids to be prepared and act once you see the signs. Remember that gardening isn’t a linear practice, and it’s normal to face challenges along the way. 

Orchids are prone to getting infestations of different pests, not just scales, but also of spider mites. And a trend you’ll notice in managing these conditions is that prevention is not only preventing them from occurring. It’s worth noting that pests’ prevention will help eliminate the pest by controlling the insect population and activity.

How To Get Rid Of Scale On Orchids: 4 Best Options


#1. Alcohol

The first option you can use to get rid of scale insects on orchids is alcohol. Among this list, this treatment is best for small numbers of scales or during the early stages of infestation. Use isopropyl alcohol on a cotton swab and rub it directly on the scale. 

However, you want to be careful with this method because you risk chilling the plant. Remember that alcohol evaporates quickly, and you may end up damaging the thin leaves of your orchids. Therefore, be fast in removing the alcohol residue, especially if the climate is windy. 


#2. Water and soap

Another quick and easy method to remove scale on orchids is washing the plant itself. With this removal technique, you want to make sure that you’re getting all the visible pests. Check under the leaves, leaf veins, and stems as scales tend to hang around in these areas. 

Use a solution of warm water and a mild soap without ammonia. Again, it’s necessary to use gentle ingredients to avoid damaging orchids. You can use this treatment every other day for a period of one month and then isolate the infected plants for another two weeks if you suspect that there are no more insects. 


#3. Horticultural oil

If the first two methods fail, you may have to resort to using horticultural oil or insecticides for a more severe infestation. Remember that it will only be effective with horticultural oil if you thoroughly apply it to the plant. Be generous in using it on the leaves’ top and bottom sides, the plants’ base, and sheaths to ensure that it contacts all the scale insects. 

What’s frustrating with scale is that if some insects survive, the infestation can happen again. It’s also worth noting to keep the oil-covered plants out of direct heat or light to avoid burning them. Additionally, don’t forget to check the label directions of your horticultural oil. 


#4. Insecticides

The final method for getting rid of scale is insecticides. When the previous three techniques failed to eradicate the insects, you have to check insecticides that are orchid-safe. Understandably, gardeners like to stay away from chemicals as much as possible, but there are cases where the infestation is hard to control. 

Check products that are safe for ornamental plants, and don’t be afraid to have a professional help you with it. Much like horticultural oil, following and checking the chemicals’ directions is a must for everyone’s safety. You also want to spray outside, but if not, you can use a plastic bag on the plant as a shield. 

More than the plants themselves, there’s a high chance that the roots need treatment too. This is evident in large infestations, so make sure to free the plant from its container and media. You may have to spray the roots with insecticides before repotting the plants in a new container with new media. 


How To Prevent Scale On Orchids

One of the best ways to prevent scale infestation is to have a holding area for new orchids. You want to quarantine them for two weeks before introducing them to your existing plants. It’s always better to be preventative, so don’t panic if you might see some scales. 

Addressing them early on would make the infestation manageable. If you did see insects, allocate spacing among the plants to prevent the transfer of scale. And as mentioned earlier, leave the treated plants in a holding area for two weeks before reintroducing them to your garden. 

Besides sanitation and quarantine, you may also introduce beneficial insects like wasps and ladybugs. They prey on scale insects, and wasps are even capable of killing scale eggs early on. 


Signs Of Scale On Plants

To eradicate scale as soon as possible, watch out for the telltale signs on plants. You may notice drooping and yellowing of leaves, and the plant itself withers or refuses to grow. Scale infestation also leaves black fungus on stems and leaves that may look like sticky sap. 



It’s safe to assume that pests are the nightmare of any gardener. Once you notice grayish-white insects on your flowers, you may have to use your knowledge on how to get rid of scale on orchids. Your first option would be alcohol and washing the infested plants with soap and water. 

If there is no improvement, you have to resort to using horticultural oils and pesticides. Remember to follow the label for these products to avoid damaging your orchids. Additionally, check which of them are safe for orchids to prevent problems.

How to Start an Avocado Farm: 4 Things to Remember

How to Start an Avocado Farm: 4 Things to Remember

Are you interested to learn how to start an avocado farm? Embarking on this journey requires time, effort, and commitment. Plus, you need to consider a number of factors including soil preparation, as well as weather conditions.

You’re probably aware that avocado trees or Persea spp, are originally from Mexico. This explains why one of the famous Mexican cuisines include avocado-based guacamole.

You can choose to grow avocado trees indoors or outdoors. If you plan to grow them in a hobby greenhouse or at home, all you have to do is to sow the seeds in pots. When they’re grown outdoors, avocado trees can grow up to 40 feet. You can al

Moreover, these trees thrive well in regions where the weather is mostly warm and sunny. However, don’t expect them to grow in areas that experience extreme temperatures during the summer and winter.


Avocado: The Superfood

Did you know that the global demand for avocados has been steadily increasing? Aside from the fact that its fruit is known for its full, buttery flavor and rich texture, it’s also packed with loads of essential nutrients that are good for your body.

A single serving of avocado fruit contains vitamin K, vitamin C, folate, potassium, vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin E, manganese, magnesium, iron, copper, zinc, and vitamin A.  It also has protein, fiber, and healthy fats. If you’re on a low-carb plant food diet, you’d want to incorporate avocados into your diet.


What are the Growing Requirements of an Avocado Tree?

Since avocado trees need to be grown in warm semi-humid climates, they only grow in U.S. Department of Agriculture (USDA) plant hardiness zones 8 to 11. However, it’s important to note that while avocado trees may be grown in those zones, they don’t always thrive well in areas that get extremely hot during the summer or frosty, chilly, or snowy in the winter. This implies that the ideal environment for an avocado tree should have moderate temperatures all-year-round.


What are the 3 Primary Groups of Avocado Trees?

If you’re planning to start an avocado farm, you need to know the 3 main groups of avocado trees: Guatemalan, West Indian, and Mexican. Each type has its own ideal growing range.


Guatemalan Avocados

A Guatemalan avocado is known for its hard skin that features plenty of warts.


West Indian Avocados

This type of avocado tends to flourish in warm climates. Unlike the Guatemalan avocado, a West Indian avocado has thin and shiny skin and could weigh up to 5 pounds.


Mexican Avocados

A Mexican avocado thrives well in tropical highland areas. Compared to the other avocado groups, the Mexican avocado is more tolerant of cold weather. In fact, it can manage to survive even when temperatures drop to 26˚F.

Moreover, this type of avocado produces smaller fruit that weighs less than a single pound and its skin has a distinct papery-smoothness to it.


Expert Tips on How to Start an Avocado Farm

Unless you’re willing to take on a long-term project, spend a considerable amount of money on planting, and wait for a period of 3 to 5 years for your first harvest, don’t get into avocado farming. However, if you’re willing to go through the whole nine yards to enjoy top yields for many years, check out this guide:


Tip #1: Plant them in areas where the temperatures are consistently cool

Be sure to plant your avocado trees in cool temperatures that can range between 68˚F to 75˚F on a daily basis to avoid fruit drop. However, when they’re flowering, or when they’re starting to bear fruit, the humidity levels shouldn’t go below 50% at midday.


Tip #2: They don’t like wind

In case you’re not aware, avocado trees have brittle branches that easily snap off. For this reason, it’s best not to plant them in areas that are mostly windy because wind can cause considerable damage to their fruit.


Tip #3: Most of them need proper irrigation

If your avocados are rain-fed, they need to have at least 1,000 mm rainfall spread out throughout each year. Before their flowering season, avocado trees require a drier season that lasts for about 2 months. On a weekly basis, avocado trees need about 25 mm water.

It’s extremely important to test the quality of irrigation water because if its pH and bicarbonates are really high, they trigger a build-up of free lime in the soil. You also need to remember that high levels of sodium and chloride can have a negative impact on your avocado plants.

Since the plant’s roots are shallow, the ideal way to apply water is via a micro-sprinkler or drip. This ensures an even distribution throughout the avocado tree’s root area.

Moreover, proper moisture control needs to be ensured in the root zone because this area tends to easily dry up.


Tip #4: Determine the soil’s suitability and prepare it accordingly

You can’t just plant an avocado seed on soil that hasn’t been prepared accordingly. To prepare the soil for planting, you need to dig soil profile pits throughout your farm. Make sure that the pits are 1.5 m deep.

Only a single put per ha is required. However, you need to dig more pits if the location is non-homogenous or hilly. Check the color of the soil, its texture, structure, patches, sitting water, concretions, hardpans, stones, and gravel.



Grow Your Avocado Trees in a Hobby Greenhouse!

Since avocado trees require specific levels of temperature and humidity, you’ll find it easier to grow them in a hobby greenhouse. The enclosed space allows you to customize the environment to meet the needs of your plants. What’s more, it protects them from strong winds and the constant threat of pests.

Learning how to start an avocado farm outdoors is great, but growing them inside a hobby greenhouse is even better.
