For flowering and fruiting plants

Choosing The Best Bloom Boosters


Finding the best bloom booster for your plant can be made easier. That is if you have enough information about the products. It's also helpful to know which products are considered to be the best in the market. It's important to be careful when making a choice.

There are different products out there, but some don't live up to your expectations. To be able to find the best one, it's essential to know how to go about the process of making the selection. Here are some things for you to think about:

Go through the label or specs of the product

The label will contain a lot of useful information about the product you are planning to buy. Different products come with different features and specifications. There are also products which are only suitable for some types of plants. While other products can be used on a wider range of species.

Also look at the components present in the product. It should have enough components to keep your plant healthy. It should also allow your plant to grow and develop well.

Solubility with water

Bloom boosters which can be applied with water or liquid are the best ones. That's because they can be absorbed by the plants easier. Powdered products have a tendency to get blown around. This means that they might affect your plants longer than water soluble ones.

Liquids enter the soil faster. When this happens, the products begin feeding your plants. Then they are able to absorb the essential vitamins and nutrients. This occurs right after you apply them.

Learn about the yield of the product

Different products have different yields. Try finding one which will give you a great yield so you can save time, effort and money. Some products are only able to work on small gardens or flowerbeds. While others can be used for bigger areas.

Learn about the yield so you don't end up spreading the product too thin. When this happens, it won't be very effective to your plants.

Find out how quick you will see improvements

This is an important factor to think about. Again, all the bloom boosters are different. Some will give you quick results while others will take more time. Of course, you'd want a product which will give you quick improvements. Otherwise, you might not know if it's working or not.

Tips In Using Bloom Boosters


It's one thing to find a great product. Another thing is to know how to use the product properly. Using these boosters incorrectly can be harmful. They might cause damage to your plants instead of helping them. Here are some helpful tips to guide you:

How to apply the bloom boosters

This will depend on the type of product you had purchased. There are different types of bloom boosters, depending on the consistency.

Powdered products are common and usually more affordable. These are best for simple gardening tasks and they usually last for about 1-2 months.

Liquid products are either in concentrate form or in dry form. For the second form, you have to dissolve it in water. This type gets absorbed into the ground easily. So it can be absorbed by your plants easily too. But with this type, you have to follow the directions for use to avoid causing damage to your plants.

When to apply bloom boosters

The application can be done at different times. When applied at the right time, the product will help your plants produce big and healthy blooms.

Applying the booster before your plants start flowering is essential. One of the most important components of these boosters is high phosphorus content. This phosphorus is essential in helping your buds bloom vigorously.

As soon as you see buds forming in your plants, then it's a great time to apply the product. This will ensure that the nutrients will go into the plant while the buds are just developing. When this happens, the buds will bloom into healthy and blooming flowers.

Applying the booster while the flowers are blooming can also be very helpful. Again, this is because of the phosphorus content which is high in boosters. If phosphorus levels are low while the flowers are in bloom, you will end up with fewer flowers.

You will also end up with smaller blossoms. But when applied at the right time, the new buds will keep on developing. Their maturity rate increases. The immune system of the plant gets enhanced too. Overall, your plant becomes healthy and flourishing.

Manufacturers of best bloom boosters frequently suggest that you use the booster once every week or every 2 weeks. Do this while your plants are in bloom to come up with the best flowers.
