Soil Condition

The soil has an important role that affects all flowers and plants’ growth. So, we can say that the reason why your hydrangeas not blooming is the soil condition. Soil affects this flower a lot. You can even decide the color of its flower by tweaking the soil condition.

As for the no-blooming problem, mostly, it is caused by the soil that has too much nitrogen in it. The solution is reducing its amount. How? You can use many methods. However, we recommend the usage of sawdust or wood chips to absorb the nitrogen.

Or, you can plant cabbage, corn or squash, that’s known as the plant that uses a high amount of nitrogen from the soil. You also can use other plants, as long as it is the type that loves nitrogen a lot. The most important here is balancing the nitrogen level in the soil that you use to plant Hydrangeas.


Fertilizer also is one of the causes of the problem you have on your hydrangeas. When you give it too much fertilizer, this flower will get too much energy, which it will spend to develop big leaves. This is the way to balance the amount of absorbed energy.

Moreover, using too much fertilizer also increase the nitrogen level in the soil. So, this is one of the causes of the problem with soil as well.How to solve it? When giving too much only causes problems, the solution is simple. Limit the fertilizer amount you give to this beautiful flower.

You don’t need to give it too often. Once in spring and once in mid-summer is enough. Or, if you use the time-released fertilizer, you can give it once in the spring. That way it will bloom magnificently during summer when you can enjoy it at its best form.

If you love gardening, you must understand that pruning is an important process to promote your plant growth. However, Hydrangeas doesn’t need it. It can grow healthily without pruning. The funny thing is you might need to do some pruning if you want to see it blooming properly.

But, the incorrect pruning method on this flower can cause the opposite. Yes, pruning it incorrectly will keep it from blooming. Mostly, it happens because you mistakenly remove the early buds before it matures and bloom.

When pruning hydrangeas, you need to know which variety your flower is. Hydrangeas are categorized into three varieties, which are:

–        Old-growth (Hydrangea macrophylla),

–        New growth (Hydrangea arborescens and Hydrangea paniculata),

–        Endless Summer.

Each variety we mentioned above has a different pruning method. As for old-growth and Endless Summer, you need to do it when the flowers started to fade. Mostly, it happens close to winter. On the other hand, you need to prune the new growth variety in late winter or early spring.

So, before pruning, make sure which type your flower falls into. Or, you can just let it grow naturally and see if it is blooming or not. As we mentioned earlier, this flower doesn’t need pruning in the first place.


Wind also could be the cause of why your Hydrangea not blooming, especially the winter wind. The bud can easily tear off before it mature. The solution to this problem is simple. You just need to protect it from the winter wind.

You can use the chicken-wire cage around it. Or, you can use stakes to support its stalk. Then, use the fallen leaves with the burlap wrap to create simple insulation surrounding the flower. This will protect the bud and let it naturally bloom in next season.


The place where you plant Hydrangeas also can cause the no-blooming problem. Mostly, it happens when you plant it on the area where it got too much shade. Hydrangeas also need at least 4 hours of sunlight a day. So, by balancing the shade and sunspot area, you can solve this problem.

Moisture in the location where you plant it also holds a big role in Hydrangeas blooming process. It needs a lot of moisture. So, make sure you water it regularly. Otherwise, it won’t only blooming, but also hydrangea not growing tall.

Each of the Hydrangea varieties also can live in a specific area. so, make sure that the variety you choose is suitable for the area where you are going to plant it.
