Yes, you can absolutely reuse compost from last year's pots, but you need to refresh it by adding new compost/nutrients and breaking it up, especially if the previous plants had diseases; otherwise, you can use it as mulch or add it to your garden compost heap, but avoid reusing it for the same hungry plants or if pests/diseases were present.
Unless plants that have been grown in the compost have indicated signs of disease then this medium is fine for reuse in whatever way you want.
If you're growing a tree or shrub in a large container, you should replenish the compost every year or two. The ideal time to do this is between February and May. Doing so will improve the compost structure and provide a fresh supply of nutrients, which can be lost quickly in pots and containers.
You can reuse old potting soil if the plant is healthy and disease-free. However, you'll want to watch out for the following issues: Rot-causing pathogens: If the plant shows signs of root rot, such as black, mushy, and smelly roots, avoid reusing the soil. You must sterilize old soil properly if you want to reuse it.

Banana peels are packed with potassium, phosphorus, and calcium — nutrients that are essential for plant growth. They decompose quickly, making them a fantastic addition to your compost pile. Plus, by composting peels instead of tossing them in the trash, you help reduce landfill waste.
Breaking Down Composting and Understanding the Basics
However, compost can only effectively improve soil quality if the organic stream remains clean. When non-compostable materials, such as conventional plastics, glass, metals, and produce stickers end up in the compost mix, they can easily derail the entire process.
Soil taken from your yard or a garden bed is too heavy and dense to use in a pot or raised bed. In containers and raised beds, soil from the ground can become easily compacted causing problems with drainage and air circulation, and it can also harbor weed seeds, insects, and diseases.
Foul Odor
A foul, rotten eggs odor indicates that your potting soil bag has gone bad.
Add Water: Gradually add water to the compost, ensuring it's evenly moist but not soggy. The compost should feel like a wrung-out sponge to provide the right environment for decomposition. Mix in Green Materials: Incorporate green materials such as kitchen scraps, grass clippings, and fresh garden waste.
It's important to remove the old soil from around the root ball to prevent root rot.
After the pile reaches around 80-90 degrees Fahrenheit, you want to stop adding greens and limit the amount of browns so that the compost can cure. Keep turning the piles regularly to add oxygen. If you have two bins, you should fill one completely, then start filling the second.
To improve the structure (tilth) of your garden soil, a fall application of compost is best. Apply a one-half inch to 3-inch layer of compost on garden beds at least once a year.
A common approach is to combine one part ericaceous with two parts normal compost; this ratio softens acidity without neutralising it completely. Adjust proportions according to plant demands: a higher share of ericaceous benefits heathland species, while more normal compost supports neutral-ground favourites.
Using synthetic fertilizers disrupts your soil pH and leads to a buildup of salts and chemicals your plants can't use. You may get big, luscious plants after a couple Miracle-Gro applications, but you'll also deplete the thing that's most important in an organic garden: the great, nutrient-rich soil.
It's dense, heavy, and holds too much water, which can suffocate plant roots. So do your plants a favor—put the shovel down. The UC Master Gardener Program recommends avoiding garden soil in containers, even high-quality garden soil, because it lacks the aeration that container plants need to thrive.
Best Potting Soil For Vegetables
Cinnamon has powerful antifungal properties, and applying the spice to plants can prevent soil-borne fungal diseases, rust, and mushrooms.
Give Old Potting Soil New Life
Some plants like rhododendrons, azaleas, blueberries, gardenias and blue-flowering hydrangeas require a lower soil pH to thrive and coffee grounds won't do that. Although coffee grounds provide some nitrogen (1% to 2%) and micronutrients, they aren't a major source of plant nutrition, Brewer said.
Citrus fruit, tomato products, and pickled food products can do harm to your compost. High acidity can actually kill the good bacteria that help break down the material in your compost pile.
Can you compost Toilet paper rolls? Toilet paper rolls are made from cardboard, so they are compostable! As long as these rolls aren't contaminated, they're a great addition to your compost bucket.
Some things, like grass cuttings and weeds, rot quickly. They work as 'activators', getting the composting started. Older and tougher plant material is slower to rot, but gives body to it, and usually will make up the bulk of your compost heap.
