Our Beginner’s Guide for Applying Bloom Booster Fertilizer

A beautiful garden happens because of hard work. When a lawn has large blooms, that is because someone in or working for the household used the right fertilizer at the right time. Your choice of fertilizer matters; a quality bloom fertilizer means bigger and more fragrant flowers. Growers with thriving plants use bloom boosters, or nutrients specifically for the growing phase. 

All plant nutrient enhancers have potassium and phosphorus, but there are variants that make different types of plants grow better. You must take care when using boosters; you need to apply this at the right time so you do not harm the root system or the stems of your plants. Keep the following things in mind when applying bloom boosters to your garden.

Know what type of fertilizer you need

Home fertilizers are often general-purpose and can be applied to everything you can grow in your backyard. Whether you have non-flowering bushes or a bed of vegetables, home fertilizers will contain the macronutrients needed for these plants. They also have a high concentration of nitrogen and are followed by phosphorus and potassium. 

For flowering plants, there are bloom boosters, which have higher levels of phosphorus. This is because phosphorus enhances bud development and helps buds mature quickly. If you have beautiful green foliage but fewer blossoms, you might have a fertilizer rich in nitrogen but low in phosphorus. Switch it up to get the abundant blooms that you want.

Know when to start applying fertilizer

The stages of flowering can be difficult to distinguish, especially when the first blooms have appeared. As a rule of thumb, when you see fresh, bright green tendrils near the stems, you should start applying bloom boosters. This means your plants are ready to sprout buds, and you want them to get the right type of nutrients to encourage flowers to grow.

Apply flowering boosters even after your plants bloom, to help them flourish throughout the growing season. Using fertilizer every week or every two weeks will help new buds to sprout as the old ones wilt. This makes your bloom season longer. For indoor plants, you can add small amounts of fertilizer throughout the year, to ensure continued growth.

Do not apply fertilizer indefinitely

Once temperatures drop, you need to stop using phosphorus-heavy fertilizer. Around October, you must scale back on the supplements and allow your plants to go dormant in preparation for the cold weather. The fertilizing process becomes counterproductive when you apply more nutrients than the plants can use. Too much phosphorus and potassium can be more toxic to your plants, and result in smaller blooms or a slower growth during the next cycle. 

Fertilizing when it is too cold will also make your roots weaker. What’s more, you might make weeds more productive instead! Give your plants a few months of rest before the next blooming season. This can be extended in areas like the Southwest, where winters are not as harsh. You can use fertilizer again when temperatures are in the 20s range, and the soil is 15℃ or warmer.


Using plant growth stimulants can result in a yield of beautiful flowers. You should know the right time to start and stop applying these enhancers, as well as what type to get.
