Feed Flowers at the Right Time

Blooms Need a Plan

Heavy flowering is not just luck. Feed at the right time, choose a suitable product, and repeat a simple routine to give ornamentals the support they need.

Start Before Buds Form

Begin in late winter or early spring, before buds appear. Feed bulbs and spring-flowering perennials in February–March; many summer bloomers start in April.

Use the Monthly Calendar

Roses need feeding March–August every 4–6 weeks; hibiscus and geraniums April–September. Feed azaleas in February and May, and lavender in March and June.

Choose the Right Feed

Slow-release granules supply nutrients for 8–12 weeks with less burn risk. Use liquid feed for a quick boost during peak bloom; it can improve flowering within 7–14 days.

Measure Each Dose

For container geraniums, use 1/4 tsp of water-soluble 20-20-20 per gallon every two weeks. Potted hibiscus gets 1/2 tsp high-K liquid feed per gallon weekly in bloom months.

Build a Simple Routine

When feeding, check soil moisture and pests. Water thoroughly before applying granular fertilizer, then record the date, product, and plant response in a simple log or tag.

Avoid Common Mistakes

Late-fall feeding can trigger growth vulnerable to freezing. Too much nitrogen favors leaves over blooms, dry soil raises burn risk, and azaleas need acidic soil.

Timing Makes a Difference

In a small test, two identical potted hibiscus received different schedules. By July, the calendar-fed plant had three times the blooms and stronger stems than the randomly fed one.

Switch with Your Goal

Use slow-release fertilizer as a spring base for steady nutrients, then add liquid feed during active bloom periods for a quick boost. Match the product to the plant’s stage.

Feed with Confidence

A reliable flowering routine comes down to timing, measured doses, and a suitable product. Follow the calendar, watch your plants, and adjust by climate and their response.
