I’ve grown annuals, perennials, shrubs and small trees in pots everywhere, from windy balconies and shady basements to vast sunbaked courtyards. And if there’s one thing I’ve learned, it’s that potted plants need us. Unlike those in the ground, they can’t fend for themselves, and nutrients get leached out fast. Without a steady supply of food and water, your beautiful pot display will fade and fizzle.
That’s why now is the moment to act. You might think your pots are just fine with fresh soil in spring, but fertilizing pots is an important job to add to your summer gardening checklist. Believe me, it really does make the difference between just surviving and truly thriving. And, there’s one product that has caught my eye: the Organic Plant Magic fertilizer shaker, available now via Amazon.
Just sprinkle it on the surface of your pots... no complicated steps, no mixing, no mess. And, with over 1,600 reviews and an average rating of 4.5 stars, it’s no surprise gardeners swear by it. Future you (and your dahlias, cosmos and lilies that are still flowering in October) will be very grateful you took the time to sprinkle a little bit of feed.
This simple-to-use fertilizer shaker is perfect for giving your pots a boost during summer. All you have to do is sprinkle a small amount on the surface of the soil. That's it.
What do the reviews say about the Organic Plant Magic shaker?

Scan the reviews, and a few things come up again and again. First, most gardeners rave about its ease of use, with reviewers loving the simplicity. No measuring, no mixing. Just flip open the shaker and sprinkle.
One five-star review from June 2025 reads: 'I wanted an organic fertilizer, and this one works. My plants are thriving in this desert Utah climate.'
Many reviewers also praise the quick results. Whether it’s faded marigolds perking up in days or a window box erupting in late-summer blooms, people are genuinely surprised by how fast and visible the difference is.
Another five-star reviewer from July 2025 reads: 'I started using Organic Plant Magic on all my indoor plants, and the difference is incredible! The leaves look greener, fuller, and overall just healthier. Even my spider plant, which has survived a lot, perked up and started sending out more babies. It’s easy to use, and I love that it’s organic and safe around my cat.'
Some reviews do comment on the price, with one four-star review from June 2025 stating: 'It’s a bit pricey, [and] it makes a mess on your concrete if it spills.'
It is always best to work slowly and carefully, to avoid any fertilizing mistakes by making a mess on decks or patios. If you do spill any feed, simply scrub with water and a hard-bristled brush, and it should wash away.
With over 1,500 reviews and consistently high ratings, this small but effective fertilizer shaker has rightly earned an impressive reputation.
While the cost might seem a little high, it is the perfect product for fertilizing sweet peas, fertilizing lilies and keeping dahlias blooming. So, a small investment now will guarantee those late summer blooms that we all want to enjoy.

How to use the fertilizer shaker?

Using the Organic Plant Magic fertilizer shaker couldn’t be easier. Simply sprinkle a small handful (about a teaspoon or less) per pot across the surface of the soil.
There’s no need to dig it in. Just apply it before your next regular watering, and let the nutrients soak through naturally.
It’s gentle, organic, and safe for container plants of all kinds. In terms of plant fertilizer numbers, it has a balanced 6-5-5 reading, so it is good for encouraging root, foliage and flower growth for all plants.
In terms of feeding pots, I would suggest applying this product once every three weeks through summer, stopping around late August to early September, as the season comes to an end.
To keep your flower pots looking tip top, be sure to keep deadheading your annuals and perennials on the patio, to encourage more blooms through until fall. This includes cosmos, chrysanthemums and dahlias. Our guide has all the information you need.
