Why Use A Bloom Boosting Product?

1. Treats the Soil

Treats the Soil

There are certain nutrients that flowers need to grow and be healthy. Unfortunately not every soil that you plant your flowers in has the right nutrients in it.

Bloom boosters are full of these nutrients because the manufacturers have added the nutrients that flowers crave right into the mixture. Once applied the soil your flowers are planted in becomes much more to their liking.

The main ingredients in a bloom boosting product that treat the soil in a manner that flowering plants like are phosphorous and potassium.

2. Produces Healthier Flower Plants


Now that you know the soil your flowers are planted in has been treated you can be a lot more confident that your flowers will now get the extra nutrients they need. Soon they will start to absorb these nutrients.

Once this absorption takes place your flowers will quickly start to take on a healthier appearance. This will also help them to make better use of the moisture they take in also.

3. Increases the Blossom Size


Flowers crave potassium and phosphorous much more than some other plants do. It is these ingredients that most dramatically affect the blossoms you get.

Contrary to belief, bloom boosters will not give you more blossoms than normal on your flowers. What they will do is make these blossoms much fuller and healthier. That makes your flowers look much better and the blooms on them last longer too.

4. Made Specifically for Flowering Plants

Flowering Plants

There are many types of generic fertilizer products in the lawn and garden marketplace. But you don’t know if they will give your flowers any healthy growth benefits. Generic fertilizers are targeted toward helping a very broad spectrum of trees and plants get some nutrition from them.

Bloom boosters, on the other hand, are specially formulated to specifically help your flowers grow. They contain nutrients that are well-known to make flowers healthier and bloom in a much fuller where. So with bloom boosters, you get a product that is specifically made for flowering plants.

Best Bloom Booster Buying Guide

As we mentioned earlier not all bloom boosting products for flowers work as advertised. To give yourself the best chance of finding one that will work for you then you need to focus on certain key characteristics of bloom boosters.

Here are the key factors to consider when choosing a bloom boosting product for your flowers:


Read the Label

Read the label so you are familiar with what you are getting with any bloom booster you are thinking about purchasing.

Every bloom boosting product has different ingredients in different amounts. Read the ingredients on the label so you have an idea what is in there as far as the amount of phosphorous, potassium and other ingredients go.

You also want to know what flowers the bloom booster you are thinking about buying works best on. One might be better for hydrangeas and another better for roses. A manufacturer will usually list what flowers their product works best on.


Water Soluble is Best

Having a bloom booster that is applied in liquid form seems to work the best. Powders can blow around and take longer to get to where they are effective.

Liquids penetrate into the ground quickly so they start feeding your flowers nutrients almost immediately after being applied.


Know the Container Yield

You also want to know how much coverage area the package of bloom booster you are about to buy has. Some bloom boosters will do a large amount of flower beds or gardens while others are meant to treat only small amounts.

You would hate to find out the bloom booster you applied didn’t work because you spread it to thin. Worse yet if you don’t know the coverage application area of your bloom booster you may not have enough to treat all your flowers.


Know How Fast it Produces Results

This is a lot more important than you may realize. Different brands of bloom boosters work at different rates. If you don’t know how fast the bloom booster you are applying is supposed to work then you won’t know when to look for results.

You want to know a general timeframe it is supposed to work in so you can try another if you don’t see results in that time frame.

What Time of Year is Best to Use A Bloom Booster?

Flower Fertilizers

If you have planted flowers from seeds the best time to use bloom booster is when the plants first start to sprout up from the ground.

For established flowers, the best time to apply bloom booster is when the flower first starts to show signs of new life. After that give it another dose of bloom booster once it has bloomed so the flowers stay blooming longer.

Here is how you mix up liquid bloom boosting products so they distribute thoroughly into the soil around your flowers when you add it:
