None of us plan to purchase a luxurious and beloved potted plant only to find that the plant is looking poorly within a year or two, is overgrown, or is starting to show signs of distress.
One of the easiest methods to cure these problems is simply changing, adding, or replacing our potted plants’ soil when it makes sense to do so.
Potted plants benefit from having their soil changed periodically to renew the nutrients and remove impaction and provide air to the root system. It also allows you to pot into a larger pot as the plant grows. The most significant benefit is that it helps remove high phosphorus levels, which can cause nutrient locking in the plant.
If you’re a gardener, a houseplant lover, someone who loves a particular plant variety, or want to spruce up an area of your home or outdoor room, potted plants will bring us all a lot of joy.
Our potted plants’ soil should be changed, topped up, or replaced for them to continue to thrive, look attractive, be healthy, and provide us with pleasure.
To have healthy and lush potted plants, they should have their soil contents changed regularly. Plants that are restricted to pots rely heavily on that soil for nutrients.
Since they do not have access to the earth where water, beneficial nutrients, fungi, bacteria, and insects exist, the only access to life-giving substances comes directly from both the water and the soil you provide.
Over time, these nutrients get depleted as the plant uses them to put down roots, grow foliage and produce flowers and fruits.
Changing their soil will mean they continue to flourish, look attractive, be healthy, and bring us the pleasure and delight that comes from having them in our homes, on patios, balconies, and yards.
When should I change potted plant soil?
As a rule of thumb, potted plants should have their soil contents changed every year if they are very prolific, and approximately every eighteen months for slower growing plants.
They should also have the soil mix changed at any time when the plant is visibly showing signs of distress from lack of nutrients such as yellowing leaves, leaf drop, drooping foliage, or discoloration.
It’s important to follow the instructions given to you on the plant card or your plant’s retailer’s adviser. The mix of soil you choose should be one specifically designed to benefit the variety and plant type.
Can I top up soil for potted plants?
Some slower plants may benefit from just a topping up of the soil by removing the plant, mixing in additional soil, and re-potting the plant. Other plants that are hungrier for nutrients (often the faster-growing plants) can benefit greatly from having the entire pot of soil replaced instead.
Why should I replace potted plant soil?
If your plant looks like it’s in distress, yellowing leaves, drooping foliage, leaves dropping, or an overall poorly look, it could just mean the plant is suffering a deficiency in nutrients and may need new soil to help bring it back to health.
An ideal time in determining if your plants would benefit from a replacement of their soil will often.
If you find your roots are root bound, or the roots have reached out of the bottom of the pot in search of more nutrients.
If your plants are beginning to become top-heavy and have outgrown their pot, it’s a perfect time to increase the pot’s size and start with a fresh mix of soil for your plant type.
Can I replace potted plant soil with used soil?
Typically it would help if you chose to re-pot into potting soil, and it should not be into the soil used by another plant. Potting mixes are made specifically to the type of plant you have and are made to provide the proper nutrients for that kind of plant to thrive. Not all soils work the same for all house plants.
Some like different PH balances, others prefer one nutrient over another, and all plants have specific needs for drainage and water retention specific to their kind. The best choice is to use a commercial mix intended for your plant variety.

|Commercial fertilizer – a chemical or natural substance added to soil or land to increase its fertility.||Minerals – a solid inorganic substance of natural occurrence|
|Bonemeal – crushed or ground bones used as a fertilizer.||Bloodmeal – dried blood used for feeding animals and as a fertilizer|
