And if you’re serious about getting the most blooms out of your plants, this full care guide on keeping geraniums blooming covers everything from deadheading to sunlight needs.
When Should You Feed Geraniums? Timing Is Everything!

Ideally, you should be feeding your geraniums throughout the different stages of their growth.
At the time of planting, a balanced, slow-release fertilizer is a good choice, as it allows for the slow release of nutrients, which can encourage early growth effectively.
As the growing season comes around, liquid bloom boosters applied every 2-4 weeks can perk up the flowers and promote healthy, vibrant blooming.
Quick Tip: Pull back on fertilization slightly after you get your desired blooming results; it helps maintain balance.
What Type Of Fertilizer Works Best?

Although this is a very general guideline, container geraniums typically do well with liquid fertilizers high in both phosphorus and potassium. This nutrient combination should give you a massive flower increase.
If your geraniums are planted in the ground, a slow-release granular blend would be much more ideal. Either opt for a balanced formula (NPK 10-10-10) or a bloom-promoting one (NPK 5-10-5).
Whatever one you choose to go with, just avoid nitrogen-heavy blends (20-5-5) at all costs!
And for even better results, make sure you’re deadheading your geraniums regularly, fertilizer works best when spent blooms aren’t draining the plant’s energy.
