Neem oil for hydrangeas is a great way of taking care of them after they have bloomed and need to be kept safe from insects and bugs. The oil is very slippery and also bitter which when ingested by the insects, either kills them instantly or destroys them slowly from the inside.
In the following article, we will talk intensively about taking care of your hydrangea plants using neem oil solution.
How To Use Neem Oil for Hydrangeas in Your Home Garden?
You can use neem oil for hydrangeas by first inspecting the plant for any pests, making the neem oil solution with water and dish soap, spraying the solution onto the plants, and lastly, making sure that there are no further infestations.
Hydrangeas are one of the most beautiful looking plants and go by hortensia. These plants are easy to grow in your garden and require less care than some of the other blooming flowering plants. One of the main ingredients rare ones that will help in keeping your hydrangeas full of life and infection-free is neem oil in solution form.
The hydrangeas are very vibrant in color, so they attract a lot more insect traffic than regular non-flowering and dull-colored plants. They may attract aphids, black vine weevils, four-lined plant bugs, leaf tiers, Japanese beetles, nematodes, rose chafers, scale, slugs, spider mites, and many other fungal diseases like leaf spot. These are only some of the most well-known attackers of the hydrangea plants.
1. Choose the Right Time
When you are using this oil, you should be able to manage the right time of using it, and this will help the effectiveness of the oil and how it works. The best time to use neem oil for hydrangeas is in the morning when the sun is out and shining bright. The sun helps to retain the oil on the plants which in return helps in keeping them safe and healthy.
You also need to make sure that you use the spray at a time when the weather is dry and there is no imminent forecast of rain showers. The water negates the use of neem oil because it can cause the oil droplets to leave the plant’s surface and flow into the soil.
That may be categorized as a soil drench, but with the oil, the soil will also be drenched in the rainwater. So make sure you choose a sunny and a dry day for your spray on the hydrangeas.
2. Inspect the Plant
The very first step in the process is to inspect the plant closely and try to see the damage that has happened, which needs the strength of the oil. The hydrangea plants have a very full appearance where the flowers are big and bright, and the leaves go all the way through the shoot.
It is generally straightforward for any bugs to hide between those parts of the plants without you ever having any clue about it. This is why you have to carefully examine the plant to look for the types of bugs present and also the extent of the infestation.
This will help you in arranging the correct about of supplies and also calculate the time and day when you should spray. You can also judge when you will need to reapply the spray. You must also aim to make sure that you check the nearby plants as well because, most times, the source and the infestation may not be from the same plant.
Now is the time that you would examine once more, and while looking for infestations on your plants or in your soil, you should definitely wear some protective gear. Most times, we have no clue, and these small buggers can get on to our clothes or knick us in the smallest way, which may change into an allergy later in the day.
In short, you must make sure that for your eyes and face use goggles and a mask, while for your body, wear rags that you can change after or wear overall, just to be safe and secure from any damage or spill. For your hands, you must aim to wear gardening gloves and the gloves are non-negotiable even if other pieces of protection are.
3. Make the Neem Oil Solution
The second step in the process is to make the neem oil solution for the spray. Now you will need three ingredients to make the spray and apart from the oil, the other two must be present in your house.
You will need a gallon of water, a good grade neem oil, and finally, a liquid dish soap. In a spray container, add the water and two to three tablespoons each of neem oil and liquid dishwashing soap to form a solution, of little bit.
This solution will appear to be translucent or even colored, depending on the type of dishwashing liquid you use. However, you are using it to properly emulsion the solution and to prevent burns from taking place.
The shelf life of this neem oil solution is great so you can make it beforehand and keep it on the shelf until the next use. Make sure that you use a non-toxic dishwashing liquid because, after all, you will be spraying it on your plants and yield.
4. Spray the Solution
The third step is to use the spray you made on the hydrangeas. As specified earlier, please wear protective gear when spraying because we do not want any strays going into your eyes or mouth.
You have also inspected the plant thoroughly, so you know what are the conditions of the plant. Start by spraying the entirety of the plant with the solution. For this, you can start from the top and make your way to the bottom, and you should be careful with this and move the plant parts here and there to get into all the small and big crevices of the plant.
Make sure that you get all the parts where there is a need. The spray is very slippery, making it a great medium for keeping insects from crawling up on your plants. Also, if the insects seem to be clinging really tight to the leaves or flowers of the hydrangeas, spray them and wait for their legs to get slippery and fall off.
It will take about a week or so for the neem oil to show any effect on your hydrangeas. This is because the effect of the neem oil spray depends on many things like the orientation of the spray, the weather around the plant, and lastly, the extent of damage to the plant. However, in the ideal case, the neem oil will start to remove any live insects or bugs invading the hydrangeas in a few days only.
You will be able to see the dead insects lying about around the plant, but for a complete and thorough removal, it is very important that adequate time is given to the plant and the neem oil. Make sure to reapply the spray after every week, so the neem oil can continue eradicating any and all infestations.
5. Prevent Further Infestations
Till now we have talked about using neem oil for removing infestations, but surprisingly enough, neem oil can also be used as a preventative measure against insects and their consequent infestations and diseases. Keep in mind that you will need to spray the solution exactly like explained above and continue the spray in intervals.
Preventing the infection is much more recommended than treating it afterward because then a lot of damage would have already been done and dusted. You can use this spray on various plants in your garden because neem works great for preventative measures in plants.
Make sure you check back the feedback of the plants after the first coat of spray in situations where no insects are present. If the feedback is positive, then continue to spray the plants in equal intervals of time, but you can also try to resume with the care measures.
On the other hand, to be more precise with the measures you are taking, you can also spray some rosemary oil, which is a naturally occurring oil and is far more pleasant in fragrance than neem oil. Both these oil works similarly where their insecticidal properties come into play, if you would like to guarantee your work and spray it all over again.
Rosemary oil is an elementary oil to find and is readily available in a spray form at the store but if you want to, you can make the spray at home with an easy recipe. The rosemary oil solution spray calls for one gallon of water and two to three tablespoons each of rosemary oil and dishwashing soap in liquid form.
Mix all three ingredients and pour the mixture into a spray bottle for use. You can keep the mix for a long time as it has a long shelf life, and this will help in a way that you can give the plant a different method to tackle the issue.
