How to Fertilize Hydrangeas: Our Formula – Sembrar100
If we talk about beautiful plants, hydrangeas have their good recognition for being one of the best looking.
Each spring is adorned with the color that hydrangeas give and that you can also get by putting into practice the fertilizer for hydrangeas.
Two aspects must be taken care of here: the first is that it be a special fertilizer for flowering plants and the second that it helps to acidify the soil, because that is what they like.
But in this introduction we do not want to tell you much more. If you want to discover all the secrets, join us in the following lines, do you think?
Why is it important to fertilize hydrangeas?
The first reason that leads to regular nutritional contributions to hydrangeas is to have an abundant and beautiful flowering. However, there are other reasons that are included in the benefits of performing this action. Here we count:
- Maintain healthy foliage with a good capacity to carry out photosynthesis processes.
- Develop appropriate morphological conditions in each flower.
- Ensure a production that remains active throughout the season.
- Promote a balance in the color of the flowers and that these are not variable due to problems with the soil conditions and the nutrients present in it.
- Reduce the chances that the plant suffers from diseases due to the establishment of parasites, viruses, bacteria or fungi in the farmland.
How often should we pay the hydrangeas?
Hydrangeas are fertilized during spring and part of summer, beginning in March and ending in July.
During early fall, it is also a good plan to apply a layer of fertilizer to help the plant recover from pruning and prepare for winter.
The most appropriate thing is that you make the subscribers every four weeks, depending on the type of subscription that you have decided to apply.
What nutrients do hydrangeas need?
Hydrangeas need balanced and majority contributions of nitrogen (N), potassium (K) and phosphorus (P).Above all, nitrogen will be very influential in the acidity and alkalinity values of the soil and what this then causes in the color of the flowers.
Magnesium (Mg) in this case is key because it helps the flowering to be much more numerous and to be maintained throughout the season. And iron (Fe), which is a determining factor in the color that will predominate in hydrangeas.
You must ensure that the other micronutrients are present in balanced doses that can be supplied by almost all types of fertilizers.
What kind of fertilizers do hydrangeas need?
Organic fertilizers will always be a great plan to provide nutrients to any type of plants and hydrangeas are no exception.
Worm humus, for example, is an ideal fertilizer because it provides nutrients while improving the conditions of the substrate and giving it acidity.
In the market you can find granulated fertilizers that make it easy to spread them over the entire surface of the plant. With subsequent irrigation, you will ensure that the nutrients penetrate the roots and that the plant is able to absorb what it needs.
It is ideal if the fertilizer contains micronutrients, especially magnesium which, as we saw above, helps flowering. And it is also a good plan that contains a dose of sulfur, since it helps keep the soil acidic and motivates the plants to be more comfortable.
Finally, there are the fertilizers in a liquid version that are applied together with the irrigation water, which greatly facilitates their absorption.
How do we prepare fertilizer for hydrangeas?
Worm humus is a fertilizer that you can contribute a couple of times a year, taking care that the amounts used are appropriate for the planting site.
It is best that you work it outdoors before planting the hydrangeas or in very small doses in plants that you have in a pot.
In the case of granulated fertilizers, these do not need preparation, but are applied directly to the surface of the substrate. And liquid or water-soluble fertilizers will have to be diluted with water according to the proportions indicated by the manufacturer on the packaging.
These are especially available for flowering plants, but you should be aware that they help keep the substrate acidic so that the hydrangeas are comfortable. Of the rest, you only have to supply it through the irrigation water in the corresponding period of time.
How do we detect if the hydrangeas need fertilizer?
The most frequent symptomatology that will tell us that a specific fertilizer contribution is needed will be:
- Lack of nitrogen: the plant will show it with rapid defoliation and outside the time it should. It can also be noticed when growth does not go at the rate that corresponds to the life span of the specimen. At the time of flowering, however, the nitrogen supply should not be too high because it will influence the growth of the foliage, but not the flowers.
- Lack of potassium: poor flowering and poor general properties in each flower.
- Lack of magnesium: a bloom that does not meet the morphological and color conditions as usual.
- Lack of iron: hydrangeas will have color variations that not everyone loves. For example, when your iron level is low you may not get the blue or purple flowers you dreamed of.
You cannot stop working with hydrangea fertilizer because it will be the action that will allow abundant flowering and, above all, good characteristics.Some growers trade the quantity for the quality of the flowers, thus promoting the development of few shoots.
You are completely free to make the decisions that are most favorable to you according to the objectives you have set for yourself, but taking into account that without a correct subscriber, the flowering will not respond to your wishes. In the end, it is giving them a little love in exchange for receiving much more love from them, don’t you think?
