Yes, dried out potting soil can still be good. If the soil has dried out, it can be rehydrated by adding water. However, it's important to check for other signs that the soil might have gone bad, such as a sour smell or the presence of mold.

Add Nutrients and Beneficial Microbes to Old Soil

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. Mix an organic fertilizer like worm castings or coffee grounds to the top few inches of garden soil.

Yes, potting soil can be reused, but it's essential to understand the conditions and precautions for doing so effectively.

Hillock advises gardeners to use recycled potting soil with plants that don't require rich soil to thrive. “If you choose to replace the potting soil in your containers, don't just toss the old stuff. Add the used potting soil to your compost pile,” he said.

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.

A similar situation occurs with potting mix in pot plants that have dried out and are unable to absorb moisture. I suggest soaking the pot plant in a bucket full of water, with added liquid fertiliser, for about 20 – 30 minutes. If you notice a lot of bubbles coming to the surface it means it's a very dry pot plant!

Hard packed soil can be fixed by aerating it, which involves creating small holes in the soil to allow air, water, and nutrients to penetrate.

Most potting soil can be stored 1-2 years without spoiling if stored properly, but its nutrients will still degrade. So, yes, of course you can use old potting soil, but it will not provide the same results that new, nutrient dense potting soil will.

Can you use the same potting soil two years in a row? ›

As long as used potting soil still looks fairly fluffy and doesn't emit a rotten odor, gardeners should be able to use it again with good results. However, if the plants formerly grown in the potting soil struggled with disease or insect problems, it's probably best to discard the mix and start fresh next season.

Steaming: Steaming is considered one of the best ways to sterilize potting soil and should be done for at least 30 minutes or until the temperature reaches 180 degrees F (82 C). Steaming can be done with or without a pressure cooker.

Keep it damp, add worms you dig up, then throw in coffee grounds, egg shells, and grass clippings. A handful of composted steer manure from a big box will add enough nitrogen to feed any plants you want to grow. If you keep it damp and turn it occasionally, this soild should be ready to grow in in a couple of months.

Many people simply throw the soil in the garbage, but it can be used in many other ways. First, the soil can simply be used to fill holes in the yard or top off landscape beds and other potted plants. The soil also can be spread thinly over the lawn or added to compost.

Generally speaking, potting soil can last for upwards of two years; however, these bags are typically targeted to specific uses, which dictates how successful they are over an extended period of time.

This is when soil sticks to itself and becomes extremely hard as it dries. This makes it difficult if not impossible to dig. It can also cause damage to soil structure by causing many hard clumps to form which become difficult to work back into the soil.

Unhealthy soil doesn't have the moisture and nutrients needed to thrive, which makes it dry, crumbling, and cracked. When you pick up the dirt, it might crumble quickly in your hands or be difficult to break apart. Proper watering and irrigation will improve the soil's condition in these instances.
