To get your big leaf hydrangea to bloom, you will need to make sure it is in a location that gets at least 6-8 hours of direct sunlight per day. You also need to make sure that it is planted in well-draining soil and watered frequently, about an inch or two of water per week depending on the temperature and amount of rainfall.
It is also important to fertilize the plant in early spring with a balanced fertilizer, followed by a second application in mid-summer. Additionally, pruning your big leaf hydrangea in late winter or early spring can help promote more flower buds and growth.
Make sure to only prune dead branches or old canes instead of the live, green stems as that can create barriers to flowering. Finally, make sure to add layers of fresh organic mulch around the base of the plant to conserve soil moisture and retard weed growth.
With the right conditions, your big leaf hydrangea should have no problem blooming.

Why is my big-leaf hydrangea not flowering?
These might include too much nitrogen fertilizer, improper pruning, lack of sun, or overly wet or dry soil. Because big-leaf hydrangeas require specific cultural conditions to grow and bloom, it is important to check that the environmental needs of the plant are being met.
Too much nitrogen fertilizer can lead to lush, green foliage, but poor or stunted flowering. To avoid this, it is best to use a fertilizer with lower nitrogen levels, or to only use organic amendments.
Prune the plant in early spring before the buds on the shrub open, as removing spent flower heads can discourage or cancel the flowering process. If removing old, dead stems, make sure a third of the shrub is left undisturbed to promote new flower buds.
In terms of sunlight, big-leaf hydrangeas need 4 to 6 hours of direct sun in order to promote floweriung. If the plant is located in too shady an area, flowering may be discouraged.
Finally, it is important to ensure proper drainage in the soil so that it is neither too wet nor too dry. If the soil becomes waterlogged, the roots will drown and the hydrangea won’t be able to take up enough water and nutrients to flower.
Conversely, if the plant is left in dry soil for too long, it can also stunt flowering. To achieve good drainage and exceptional root health, try planting in a raised bed or in well-draining soil.
By making sure your big-leaf hydrangea is planted in the right kind of soil, given the proper amount and type of fertilizer, and is in an area that receives the right amount of sunlight, you can help ensure that the flower buds are able to develop and bloom.
How do you fix hydrangeas that don’t bloom?
If your hydrangeas are not blooming, the first thing to check is the lighting. Hydrangeas need at least four hours of direct sunlight each day, so if your plants are in a shady spot, this could be the reason.
You may also want to check the soil – hydrangeas need moist and well-drained soil, with a pH between 5. 5 and 6. 5. If the soil is too alkaline, the plant may struggle to absorb the nutrients it needs to produce blooms.
Additionally, ensure that you are fertilizing the plant regularly, although if you’re using too much fertilizer, this can cause the plant to produce foliage rather than flowers. Pruning can also help to encourage blooms – if your hydrangea plants are overgrown, they may be spending their energy on producing leafy stems rather than blooms.
Remove any dead or damaged stems and reduce the size of remaining stems by one third to one half. If all else fails, you could try transplanting the plant to a sunnier spot with well-drained soil.
Is Miracle Grow good for hydrangeas?
Yes, Miracle Grow is an excellent fertilizer for hydrangeas. Miracle Grow contains a variety of nutrients that help keep your hydrangeas healthy and vibrant, including nitrogen, phosphorus, and potassium.
These are essential elements for good flowering, strong stems, and healthy foliage. With Miracle Grow, your hydrangeas will look more beautiful and flourish better in your garden. Miracle Grow can also provide beneficial microbes that help promote good root health and development.
Miracle Grow also improves soil structure and promotes better nutrient availability. When using Miracle Grow, be sure to carefully follow the instructions on the package to make sure you are applying the right amount to your hydrangeas.
Does Epsom salt help hydrangeas bloom?
Yes, Epsom salt can help hydrangeas bloom. Epsom salt is an easily available and cost effective way of providing essential nutrients to hydrangeas and other flowering plants. It is composed of magnesium and sulfate and it is easily absorbed by plants.
Magnesium is essential for photosynthesis, which helps to produce food for a plant’s flowers and fruits. Sulfates, on the other hand, help make certain nutrients like potassium, calcium and phosphorus more available in the soil.
When using Epsom salt for hydrangeas, the recommended application rate is one tablespoon per gallon of water. The solution should be applied at the base of the plant directly onto the soil around the roots.
Sometimes, Epsom salt can be applied to the leaves for even quicker results. Adding Epsom salt to the soil also helps to raise the pH of the soil, which can be beneficial for hydrangeas. As a result, plants will be able to better access their nutrients and they will be encouraged to bloom and produce healthy blooms.
How do you save a struggling hydrangea?
If your hydrangea is struggling, it may be suffering from a range of ailments that can be addressed with some simple gardening techniques and preventative care.
First, ensure you are watering the hydrangea correctly. Hydrangeas need about 1-2 inches of water per week and it is best to water them deeply once a week rather than give them light sprinklings of water more frequently.
If the soil is dry, ensure you soak it deeply.
Second, check the soil and make sure it drains properly. Hydrangeas prefer soils that are slightly acidic, with a pH between 5. 0 and 6. 5. If the soil is too alkaline, it may be preventing the plant from accessing the nutrients it needs.
You can use a soil test kit and soil amendments to adjust the pH, if necessary.
Third, use mulch and fertilizers to promote healthy growth. Since they are heavy feeders, hydrangeas need plenty of nitrogen and phosphate to help them bloom brightly and stay healthy. You can use organic mulch to help retain moisture and organic fertilizers to provide them with additional nutrients.
Fourth, check your hydrangea for signs of pests and diseases. Aphids, caterpillars, and spider mites all feast on hydrangeas and can cause significant damage if not treated promptly. If you spot any of the telltale signs, you can treat with insecticide.
Alternatively, you can use a natural remedy such as neem oil. Beware of fungal and bacterial diseases such as powdery mildew and fire blight, which can quickly spread and kill entire plants. If you suspect either of these, treat your plant with appropriate fungicides and antibiotics immediately.
Finally, if the problem persists, consider pruning the hydrangea to promote healthier growth. Hydrangeas should be pruned annually in early spring, before flowering. Remove any dead, diseased, or damaged branches, as well as branches that are crossing over each other or growing too far out.
With the right care and attention, you can save a struggling hydrangea and bring it back to its full health and glory.
What is the fertilizer for big-leaf hydrangeas?
The fertilizer used for big-leaf hydrangeas will depend on the age and condition of the plant. Generally, plants that are one to three years old should get a balanced fertilizer, such as 10-10-10, at a rate of 1/4 to 1/2 pound per 100 square feet of area.
Mature plants can benefit from an acid-forming fertilizer such as an 8-8-8 or a 6-3-3-3. These fertilizers should be applied at a rate of 2-3 pounds per 100 square feet. As with many plants, too much fertilizer can create problems such as excessive leaf growth and poor flowering, so it is important to follow the label instructions carefully.
For hydrangeas that are not growing or blooming well, a slow-release fertilizer that is specifically formulated for container-grown plants is often beneficial. These fertilizers contain a mixture of essential micronutrients, such as magnesium, iron, and zinc, which help improve plant health and overall flowering performance.
For varieties of big-leaf hydrangeas that are grown in soils containing lots of organic matter, like compost, periodic topdressing of organic fertilizers (such as manure, fish emulsion, or compost tea) can provide beneficial nutrients to the soil.
Regular soil testing is recommended to monitor nutrient levels and pH in the soil to ensure that the best fertilizer and fertilizer rate is used.
What month do you fertilize hydrangeas?
The best time to fertilize hydrangeas is in late March through late April, or the early part of the growing season. As hydrangeas actively start to grow, they will benefit from a balanced fertilizer such as 10-10-10.
Choose a product that has equal amounts of nitrogen, phosphorus and potassium. After the initial fertilizing, it’s a good idea to fertilize your hydrangeas one more time every 5-6 weeks during the growing season, to help keep the plants vibrant and healthy.
Feel free to reduce your last application to biweekly, if the flowers stop their rapid bloom.
What should you not use Miracle Grow on?
Miracle Grow is a liquid plant nutrient that is used as a nutrient supplement for garden plants, shrubs and trees. Though it can be used on any kind of plant, it is important to note that there are certain kinds of plants that you should not use Miracle Grow on.
These include succulents, bromeliads, citrus plants, ferns, ivies and cacti, which may be sensitive to the high levels of fertilizer and may be damaged if Miracle Grow is used. In addition, it is important to pay attention to the directions and not over-fertilize, as this can also cause damage to your plants.
It is also important to note that Miracle Grow is not meant to be a substitute for regular watering—plants still need to be watered regularly in order to thrive. Miracle Grow is best used in addition to regular watering, in order to give plants the nutrition they need to grow strong and healthy.
Can you use Miracle-Gro Shake and Feed on hydrangeas?
Yes, Miracle-Gro Shake and Feed can be used on hydrangeas. It is a balanced formula that helps to promote strong growth and beautiful blooms, so it’s a great option for hydrangeas. The fertilizer helps to nourish the soil and encourages plants to produce more vibrant blooms.
To use Shake and Feed, simply grab the shaker container and sprinkle it evenly over the soil near the base of the plant. Be sure to keep the fertilizer away from the plant’s stems and leaves, and water afterwards.
Reapply every 1-2 months in the growing season for beautiful blooms all season long.
Do hydrangeas need special fertilizer?
Yes, hydrangeas need special fertilizer to help them thrive and bloom. If you want the best blooms, then it is important to use a fertilizer designed specifically for hydrangeas. Hydrangeas need balanced nutrition for best growth, and there are many fertilizer options to choose from in your garden center or online.
Most fertilizers should be applied every two to three months during the blooming season and every few weeks during peak bloom times, though you should check the directions on the specific fertilizer you’ve chosen.
It is also important to be careful not to over-fertilize your hydrangeas as too much fertilizer can cause foliage to die and damage the roots.
What to give hydrangeas to help them bloom?
If you want to give your hydrangeas the best chance of blooming, you should make sure you are providing them with the right balance of nutrients, temperatures, and humidity. First, provide the hydrangea with a well-draining soil that has a pH level between 5.
0 and 6. 5. This will ensure they are getting enough acidity to properly feed on the nutrients in the soil so they can grow and bloom. It is also important to make sure the soil stays moist but not soggy, as hydrangeas can suffer from root rot if they are over watered.
Additionally, ensure they are getting bright, indirect light and that the ambient temperature doesn’t drop too low (45°F is the lowest recommended temperature for growing hydrangeas). Finally, make sure the air is humid enough to keep the soil moist.
If necessary, mist the plants at regular intervals to boost the humidity. By following these steps, you can give your hydrangeas the best chance of blooming.
What should I do if my hydrangeas don’t bloom?
If your hydrangeas do not bloom, there a few potential explanations and solutions. Make sure the area the plants are in receives plenty of direct sunlight throughout the day, as hydrangeas need at least 6 hours of light in order to flower.
Also, plants need adequate drainage, so ensure that you’re using well-drained soil and that there aren’t any drainage issues with your garden or plot. Regular pruning can also help increase flowering, as it keeps plants healthy and vigorous.
In the early winter or late fall, prune your hydrangeas about a foot from the ground. If none of these tips work, you may need to check for pests or disease, as infestations or fungus can prevent plants from flowering.
If this is the case, you should work with an experienced gardener or local horticulture office to diagnose and treat the issue.
How much Epsom salt do you put on hydrangeas?
When applying Epsom salt to your hydrangeas, it is important to follow the directions on the label. Generally, you will need 1 tablespoon of Epsom salt for every 9 square feet. For example, if your hydrangea bed is 9 square feet, you will need one tablespoon of Epsom salt.
If your hydrangea bed is 18 square feet, you will need 2 tablespoons of Epsom salt. It is important that the Epsom salt is applied evenly to the soil around your hydrangeas. You can sprinkle it directly around the roots, or add it to your watering can and apply it evenly when watering.
When applying Epsom salt, it is important to water the plants immediately afterwards to ensure that the Epsom salt gets absorbed into the soil. Doing this once a month can help your hydrangeas grow lush and green and provide them with the magnesium they need to produce beautiful blooms.
Can I sprinkle Epsom salt around plants?
Yes, you can sprinkle Epsom salt around plants. This is beneficial because Epsom salt helps to nourish the plants and increase their nutrient absorption. It also provides beneficial magnesium and sulfur that plants need to stay healthy.
Additionally, Epsom salt helps to create stronger cell walls, so it can help plants to fight off disease and stress. For best results, dissolve one tablespoon of Epsom salt in one gallon of water and apply the mixture directly to the soil around the plants every two weeks.
For adding Epsom salt to a pre-existing landscape, use one pound of Epsom salt for every 10 square feet of landscape. Be sure to keep the amount of salt used to a minimum so that it does not damage the soil.
If Epsom salt is used in the correct amount, it can be a great benefit to the health of your plants.
