Clemson Cooperative Extension recommends controlled-release fertilizer two to three times during the growing season or liquid fertilizer every two weeks. UF/IFAS gives the same seasonal schedule for controlled-release fertilizer, while recommending a complete fertilizer monthly. Choose based on the schedule you can follow, your plant’s growing conditions, and whether the fertilizer supplies iron and manganese.
How the recommended schedules compare
| Fertilizer format | Gerbera schedule | Guidance |
|---|---|---|
| Controlled-release granules | Two or three applications during the growing season | Clemson Cooperative Extension and UF/IFAS |
| Liquid fertilizer | Every two weeks | Clemson Cooperative Extension |
| Complete fertilizer | Monthly | UF/IFAS |
The liquid-feed intervals differ by source; they are separate recommendations, not a single universal schedule. Use the directions for your selected product as well as the relevant extension guidance.

When slow-release granules may suit your routine
Controlled-release granules mean fewer scheduled applications: Clemson and UF/IFAS each recommend applying them two or three times across the growing season. They may be convenient if you prefer not to mix and apply liquid fertilizer regularly.

NC State Extension explains that warmth and moisture affect how controlled-release fertilizer releases nutrients, and that slow release can be too slow for fast-growing crops. This is general container guidance, not a gerbera-specific comparison trial. Follow the fertilizer label for the correct amount and confirm that it is suitable for your plant and growing setup.

When liquid feed may suit your routine
Liquid fertilizer is an option if you are comfortable feeding on a recurring schedule. Clemson’s gerbera guidance says every two weeks; UF/IFAS instead recommends a complete fertilizer monthly. Apply according to the selected product’s label rather than assuming these intervals are interchangeable.
Container media can lose nutrients through frequent watering. The University of Illinois Extension advises applying liquid fertilizer to moist media and following product directions. This is general container advice, not a gerbera-specific test. University of Illinois Extension: Fertilizing Container Gardens.

Check for iron and manganese
When choosing either format, check the label for iron and manganese. Clemson notes that gerberas can develop deficiencies in both, particularly in potting soil, and recommends fertilizer or foliar spray containing these nutrients. UF/IFAS likewise advises looking for them in fertilizer or foliar spray. A product category such as controlled-release fertilizer for flowering plants with iron and manganese may fit this guidance, but verify the label and use its stated application rate.
Does one format produce more flowers?
The cited home-gardening guidance offers schedules for both options, but does not report a direct trial showing that granules or liquid feed produce more gerbera blooms. There is no supported bloom-count or growth advantage to use as a tie-breaker. Treat the choice as one of application frequency and fit with your watering routine, not a proven contest between formats.

Keep greenhouse fertilizer rates separate
Commercial gerbera production guidance can describe concentrated nutrient programs for greenhouse conditions. Those rates are not a home-pot recipe; do not transfer them without suitable expertise and product-specific directions. The University of Wisconsin–Madison Extension Master Gardener Program’s gerbera material is available here.
