Favorite Fall Fertilizers for Flowering and Fruiting in Pots

As the weather begins to shift and summer starts to wane, your container garden doesn’t have to slow down. In fact, fall is a prime time for pushing out a final flourish of blooms and bringing in a bountiful harvest from your fruiting plants. The secret? Feeding them right.

Let’s talk about the best fall fertilizers to keep your potted flowers glowing and your edibles going.

Fall often brings cooler temperatures, but your containers are still actively growing. Late-season flowering plants and fruiting veggies like tomatoes, peppers, and strawberries need an extra boost of nutrients to keep producing.

𝐅𝐞𝐫𝐭𝐢𝐥𝐢𝐳𝐢𝐧𝐠 𝐧𝐨𝐰 𝐬𝐮𝐩𝐩𝐨𝐫𝐭𝐬:

* More blossoms and fruit

* Stronger root growth before winter

* Better resistance to cooler temps and disease

The needs of your containers depend on whether you’re growing for flowers or fruit, but here are some basics:

Choose a bloom booster fertilizer with a higher middle number (phosphorus).

If you’re growing edibles, opt for organic fertilizers when possible. These break down more slowly, feeding your plants naturally while improving soil health.

𝐓𝐫𝐲:

* Compost tea

* Worm castings

* Fish emulsion

* Seaweed extract

* 𝐖𝐚𝐭𝐞𝐫 𝐟𝐢𝐫𝐬𝐭! Fertilize when the soil is moist to avoid root burn.

* 𝐃𝐨𝐧’𝐭 𝐨𝐯𝐞𝐫𝐝𝐨 𝐢𝐭.. A little goes a long way—especially in fall when plants are slowing down.

* 𝐀𝐩𝐩𝐥𝐲 𝐢𝐧 𝐭𝐡𝐞 𝐦𝐨𝐫𝐧𝐢𝐧𝐠 so plants have time to absorb nutrients before cooler evening temps.

* 𝐒𝐭𝐨𝐩 𝐟𝐞𝐫𝐭𝐢𝐥𝐢𝐳𝐢𝐧𝐠 𝐨𝐮𝐭𝐝𝐨𝐨𝐫 𝐩𝐞𝐫𝐞𝐧𝐧𝐢𝐚𝐥𝐬 4–6 weeks before your first expected frost to help them harden off.

Top off your containers with fresh mulch (like straw or shredded bark) after fertilizing. It locks in moisture, keeps soil temps stable, and makes nutrients last longer.

Even as the days shorten, your container garden can keep blooming and fruiting beautifully—with just the right kind of fall feeding. 🪴💪🍂
