How To Recharge Your Soil in Containers | American Meadows? ›

Start by scraping away the top-most layer of 'crusty' soil, leaves, pine needles, or whatever else your containers have collected over the off-season. Give the soil beneath a quick turn with a cultivator. If the soil level has dropped, mix in potting soil or garden mix to fill the planter back up.

Add Nutrients and Beneficial Microbes to Old Soil

Here are some ways you can add nutrients and organic matter to soil: Add a handful of a slow release fertilizer like manure. Mix in one part compost for every three or four parts of the old potting mix. Apply a liquid fertilizer like compost tea every two weeks.

Remove about a third of the existing potting mix, along with any clumps or remaining plant roots. Sprinkle a few handfuls of perlite over the old potting mix. Perlite is a key ingredient that allows air to move freely through the container. Add a healthy layer of fresh compost.

“Another option for gardeners who have larger containers is to remove only the top 6 inches or so of the old potting soil and replace it with new potting soil,” he said. “Since they aren't replacing all the soil, they're saving money while still refreshing the upper area, which will aid in root growth.

Thankfully, there is one method that will consistently rewet super dry potting soil; wetting and mixing it with very warm or hot water and then hand turning and mixing it (be sure to wear water-impermeable gloves). The heat helps the peat and compost easily take up water again.

Simply add organic debris to the soil surface and let your “underground herd” break it down. As it does, it will improve your soil's texture and make nutrients available to your plants. So don't be shy about applying copious amounts of organic residue to your soil.

If your garden soil has poor tilth, it can be improved by adding organic matter, such as compost, manure, sawdust, leaves, lawn clippings, or peat moss. Be careful to avoid excessive amounts of organic matter: for example, large quantities of manure can cause excessive salt build-up.

Remove about one-third or more of the old potting mix surrounding the plant's roots. As it grew, your plant removed some or all of the nutrients in the current mix, so you'll want to give it fresh potting mix or soil. Pour a layer of fresh potting soil into the empty planter and pack it down, removing any air pockets.

How to Apply Fertilizer. It's easier than you think, but don't just tip fertilizer into your potted plants. Hillman recommends diluting the fertilizer in a ratio of ¼ to ½ teaspoon fertilizer per gallon of water. "I tell people to dilute it a little more than the package says to be on the safe side," he says.

Adding compost or garden soil can be beneficial

Most gardeners make potting soil by combining perlite or vemiculite with peat or sphagnum moss. Two other organic materials that you could add to your potting mix are leaf mold and compost, which offer a wide spectrum of nutrients.

The Best Way To Improve Garden Soil

The single best thing you can do for your soil is to add organic matter. and the best organic matter is compost. Compost is simply once-living matter (leaves, kitchen vegetable scraps, garden trimmings) that has decomposed into a dark, crumbly substance.

Add some blended topsoil and compost if you notice that your raised bed has shrunk significantly. Leafy greens and herbs need at least 6 inches of growing depth, while tomatoes, peppers, and other deep-root crops require 12-18 inches of nutrient-rich soil.

How Often to Replace the Soil. It really depends on the plant, says Myers. "Faster-growing houseplants, like pothos and African violets, will benefit from annual repotting [with fresh soil]. Slower-growing plants, like cacti and sansevieria, or mother-in-law's tongue, can be repotted every one-and-a-half to two years."

Start by scraping away the top-most layer of 'crusty' soil, leaves, pine needles, or whatever else your containers have collected over the off-season. Give the soil beneath a quick turn with a cultivator. If the soil level has dropped, mix in potting soil or garden mix to fill the planter back up.
