Read on to discover the best ready-to-use liquid fertilizers that will WOW your outdoor containers, flower beds, vegetable gardens and more with vigorous growth and a bountiful harvest

Why Use Liquid Fertilizers on Outdoor Plants?

Liquid plant fertilizers provide a quick shot of readily available nutrients compared to slower release granular options. For outdoor plants, liquid foods offer key advantages:

  • Fast absorption: Nutrients go straight to the roots rather than waiting to dissolve into the soil first.

  • Easy to apply Use a watering can hose attachment or foliar sprayer to feed plants right away.

  • Works quickly: Plants show a visible growth surge in just days after application.

  • Complete nutrition: Macro and micronutrients are present versus a basic NPK fertilizer.

  • Precision delivery: No guessing how much fertilizer you’re applying. Measure it exactly.

Liquid plant food gives an instant nutritional boost at key times, like after transplanting or before blooming, complementing granular fertilizer’s slow release.

When to Use Liquid Fertilizers Outdoors

Liquid plant foods deliver targeted nutrition when plants need it most:

  • After transplanting or repotting: Reduce shock and energize root growth.

  • Before flower and fruit production: Boost bud development and fruiting.

  • Early in the growing season: Establish vigorous growth when establishing or waking dormant plants.

  • During growth lags: Kickstart growth if plants seem stunted or undernourished.

  • After pruning: Direct energy towards regrowth.

  • As an occasional nutritional supplement: Provide a periodic nutrient surge between feedings of granular fertilizers.

Follow label instructions on frequency to avoid overfeeding with liquid plant foods.

Wondering WHAT Fertilizer To Use & WHEN? The 4 Best Organic Liquid & Granular Products I Use


What fertilizer should I use for outdoor plants?

Comfrey, nettles and liquid from wormeries all make effective liquid fertilisers if used in large amounts.

How do you apply liquid fertilizer to outdoor plants?

To fertilize outdoor plants, run a soil test to know what nutrients are missing. Dilute a liquid fertilizer with water in a watering can and pour it onto the soil.

The fertilizer should be applied at the dripline of the plant and not touch the stems or leaves of the plant to prevent fertilizer burn.

Which fertilizer is right for a container garden?

Unlike perennials, container gardens, annuals and vegetables need more nutrients and benefit from a slow-release, low-nitrogen fertilizer. However, not every fertilizer is right for every plant or climate. Fertilizer labels show three primary micronutrients required for plants to flourish.

What type of fertilizer should I use for potted flowers?

The best plant food for potted flowers is a higher phosphorous (P) fertilizer. That means the center number on the label is largest. Now that we know which type of fertilizer to use for feeding potted plants, the next question is whether you should use liquid or granular (aka: slow release)?
