Factors to Consider while Choosing the Best Fertilizer for Hydrangeas
Although the price of the product is a concern that most customers and gardeners have, there are many other factors you must keep in mind. Some of these have been mentioned below:
• The Soil in Your Garden
Hydrangeas work best with soil that is light, which makes drainage easy. If you have soil that is heavier, or clay-like, you should consider adding compost to it. Otherwise, you would also add leaves and barks, both of which are organic fertilizers. These will increase the levels of nutrients in the soil.
You should check how alkaline or acidic your soil is, and what your plant loves. Based on that, you could pick a supplement that will work with those pH levels. Also, check for the level of fertility by doing a soil test.
• Variety of Hydrangea
Each type of hydrangea has different needs in terms of plant food, and each requires a different application time. For instance, smooth hydrangea plants require fertilization only once a year, during winter.
Bigleaf plants require several applications throughout the first half of the year. And panicle hydrangeas and oakleaf hydrangeas work best with two applications, once in April and once in June. Also, Hydrangea macrophylla is a species of the family Hydrangeaceae, native to Japan.
There are other small factors, too, such as ease of use. For example, some products do not need to be mixed before use, which is perfect for gardeners who like to save time would
What is the Best Time to Fertilize Hydrangeas?
Usually, hydrangeas grow best when fertilized one or two times during the year. Several experts and hardcore gardeners also mention that you should apply fertilizers twice, once during fall, and then once during spring.
That is because when you first fertilize during spring, and the product starts doing its magic, your plant does not have to undergo the heat of the summer or the chilliness of the winter. And that is why growth is smooth and not stunted.
If you want, you could also plant and fertilize your flowers somewhere during the early summer. That time frame will ensure that it is not too hot for your flowers to bloom and flourish. Make sure to add the plant food when you see buds. Also, make sure that the flowers have not already bloomed yet.
Although most experts say that fertilizing hydrangeas twice a year will be sufficient, you should do your research. Some fertilizers can last up to eight weeks, while a few do not last more than a week.
If you are making use of a fertilizer that is fast-release, you could make a light application during March, May, and July. Remember, too much could increase the risks of fertilizer burn.
Note: You can fertilize endless summer hydrangea in spring for blue flowers.
How to Fertilize Hydrangeas in Best Way?
Even though some people advise to make a special mix of plant food, these flowers do just fine with little to a regular amount of fertilizing. Knowing how to fertilize limelight hydrangeas is just as important as picking the right product to do the job.
Avoid spreading the supplement around the base. Instead, put it around the branches, around the drip lines.
If you have chosen a slow-release form of supplement, do not forget to cover it slightly. This will help activate the product, initiating the slow release of nutrients. You could provide the plants with a light dose of liquid iron twice a year, which will keep the leaves a healthy green color.
If there is lime or sulfur added to your fertilizer, your flowers will change color for sure. Hydrangeas turn pink when they are treated with lime, and when treated with sulfur, they turn blue. Both the color changes are gradual. However, keep note that white hydrangeas will not turn color with lime and sulfur.
It is a good idea to lightly fertilize your flowers in March, May, and July. Too much of supplements can burn the plants. This will first show up on the leaves of the plant; they will look scorched.
How much product should be used on a plant?
It is best to do a soil test to understand how much plant food you would require for your plants. Usually, the packet of the fertilizer will have clear directions on it to help you.
Is it possible to fertilize a plant too much?
Yes, it is. Too much of the supplement could not just burn the leaves of the plant, but also stunt its growth. One important note is that coffee grounds help to arise extra acidity in the soil around hydrangeas. For proper application, read the instructions and labels carefully. Also, if you are ever feeling doubtful, be cautious, and use only a little bit of the product.
What kind of hydrangea fertilizers should I use?
These supplements come in two forms in general – liquid or granular. The first kind allows fast action and can be applied when watering the plant. The latter gives comparatively slower action, releasing nutrients for the plant over the course of many months.
Should I fertilize a plant that is looking sick?
You need to figure out what is making the plant weak. Before worrying about the fertilizer, consider other options. For instance, check if the plant is getting enough water and light. Also, check for signs of any pests or diseases.
Since flowers are precious things that require love and care, it only makes sense to provide them with the top supplements. The items mentioned above are some of the best hydrangea fertilizers in the market now. These will ensure you vibrant, full, and beautiful flowers to beautify your garden.
