What Is a Bloom Booster?

- Flowering plant fertilizers, including roses, vines, and bulbs, generally require a higher amount of phosphorous (the packaging on these bloom fertilizers reads typically 15-30-20).
- Nitrogen is an essential part of chlorophyll production via photosynthesis, so the nitrogen level may be too high if you have beautiful and abundant foliage but no blooms.
- Potassium is needed for photosynthesis, and it also regulates the plant’s numerous metabolic functions for seed and fruit development.

When To Add Bloom Booster
Do you want to offer care to your plants in the best way possible? you can add fertilizer as soon as the first buds start forming. Doing this will ensure that your plants have enough phosphorous to help in circulating water and producing chlorophyll.
Besides that, you also need to fertilize your flowering plants with the bloom booster as they are blooming.
The key is to use the bloom booster every one to two weeks. Doing this will help you to increase the mineral absorption and metabolism of the plants. You can use it for all your plants when they are in the flowering phase.
If you don’t know how to identify the flowering phase of your plant, then one sign you can check is when new tendrils emerge. You must add the best bloom booster to improve the yield when that happens.

When To Stop Using Bloom Booster?
In general, the best time to stop using phosphorous-heavy bloom booster fertilizer is when the temperatures start to drop, particularly in fall.
Around October, slowly begin to cut off how often and how much you use a bloom fertilizer to offer your plant some time to settle in and acclimate to the cooler weather.
If you live in a region with mild winters, give your plants a few months of rest before beginning the following year’s blooming season.
