Homegrown mushrooms allow you to enjoy these fungi anytime in your own home. The best variety for home growing is oyster mushrooms, though you can use any type.
Store bought mushroom propagation is quite easy, but you should choose fungi from organic sources. Propagating store bought mushrooms from the ends just requires a good fruiting medium, moisture, and the proper growing environment. Read on to learn how to grow mushrooms from ends.
Store Bought Mushroom Propagation
Mushrooms in cultivation are grown from spores. Spores can be difficult to locate and growing mushrooms in this manner takes a bit longer than re-growing mushroom ends.
When growing mushrooms from store bought stems, the process is quicker because you don't need to rely on spores and can use the mycelium already on the fungi. Spores become mycelium, so you are essentially cloning when re-growing mushroom ends.
Mushroom "seed" is called spore, spawn, or inoculum. These need a moist humid environment and then become cottony structures called mycelium. You have probably seen mycelium in an overly moist compost bed or even just when digging up soil.
The mycelium "fruits" and produces the fungi. Mycelium bunches up into primordia, which forms mushrooms. The primordia and mycelia are still found in harvested mushrooms at the stem where it once grew in contact with soil. T
his can be used to produce clones of the mushroom. Simply propagating store bought mushrooms should produce edible copies of the parent fungi.

How to Grow Mushrooms from Ends
Some of the simplest natural processes end up becoming quite complex when humans try their hand at it. Mushroom growing is just such a process. In nature, it is just a combination of luck and timing, but in cultivated scenarios, even getting the proper medium is a chore.
For our purposes, we will use straw as our bedding. Soak the straw for a couple of days and then pull it out of the container. You can use any moistened cellulose material for the bedding, such as hamster bedding or even shredded cardboard. Now you need a couple of nice, fat, healthy oyster mushrooms. Separate the ends from the tops. The ends are where the fuzzy, white mycelium is located. Cut the ends into small pieces.
The best size for growing mushrooms from store bought stems is ¼ inch (6 mm.). You can use a cardboard box, paper bags, or even a plastic bin to layer your medium. Place some of the straw or other moist material at the bottom and add mushroom end pieces.
Do another layer until the container is full. The idea is to keep all the medium and mycelium damp and in the dark where temperatures are 65 to 75 degrees F. (18-23 C.). To this end, add a layer of plastic with holes poked in it over the box. If you used a plastic container, top with a lid and poke holes in that for air flow. Mist the medium if it looks like it is getting dry.
After about two to four weeks, the mycelium should be ready to fruit. Tent plastic over the medium to preserve moisture but allow the fungi to form. In about 19 days, you should be harvesting your very own mushrooms.

How do you grow mushrooms from existing mushrooms? ›
The Cloning Process
All you need to do is harvest a piece of tissue from a mushroom fruitbody, place it on agar, and allow the mycelium to grow out until you have pure culture. Easy! This strategy works because the mushroom fruitbody, even after being picked, is still a living, breathing, manifestation of mycelium.
How do you harvest spores from store bought mushrooms? ›
Place the mushroom with the gills face down onto the paper and pop a glass over the top. Leave this for 24 hours. When you return, remove the glass and gently lift the mushroom. The spores will have fallen from the cap and you should see a print on the paper, which replicates the gill pattern from the mushroom.
How to grow button mushrooms from spores? ›
You can grow them at home by making a mixture of equal parts compost and manure and filling a tray with it. Then, add spores over the surface and wait for the mycelium to form, which is a network of filaments that the mushrooms sprout from. After a few weeks, you'll see tiny white button mushrooms growing.
Can I grow mushrooms from store-bought mushrooms? ›
The best variety for home growing is oyster mushrooms, though you can use any type. Store bought mushroom propagation is quite easy, but you should choose fungi from organic sources. Propagating store bought mushrooms from the ends just requires a good fruiting medium, moisture, and the proper growing environment.
Can you bury a mushroom to grow more? ›
After a mushroom block stops producing, you can bury it to get some more flushes from the soil surface!
Can you take spore prints from store-bought mushrooms? ›
Freshly picked wild mushrooms works the best for spore prints because store bought ones may be too old. However, if you can't find any wild mushrooms, you could give store bought ones a go, but be aware that it may not work, or may be a much lighter colour. Materials: fresh picked wild mushrooms.
Are store-bought mushrooms sterile? ›
Cultivated mushrooms are grown in sterile compost that has been pasteurized to remove harmful bacteria. The specks of dirt that you see on store-bought mushrooms aren't harmful to consume, but they aren't very appetizing either. Unlike washing other types of produce, mushrooms do require some special handling.
How do you get mushrooms to release spores? ›
Remove the stem from a fresh mushroom, then put the cap gill side down onto a piece of paper or sterilized tin foil. Put a drop of water on the cap, then cover it with a bowl and let it sit for 24 hours. Remove the bowl and cap to reveal your spores.
How to grow mushrooms at home without spores? ›
To generate mushrooms without spores, one must first grow the mushroom tissue culture known as mycelium. An agar plate, a sterile petri dish with agar as a growth medium, is required for this. In the right environment and temperature, the agar will support fungal culture.
Mix the mycelium and your freshly brewed coffee grounds in the jar, cover, and store in a dark place. Keep the temperature at 20-25°C for 2-3 days, until the grounds are completely covered with white mycelium. Then add 1-2 cm of freshly brewed coffee grounds and wait for the mycelium to cover it up once again.
Should you cut or pull morels? ›
When you find a morel mushroom, you should pinch or cut the stem at ground level. This leaves the “roots” in the soil and increases the odds that it'll propagate there again next year. This claim has been around for as long as humans have eaten fungus.
Should you cut or pull mushrooms? ›
The first study often cited is a long-term study (Mushroom picking does not impair future harvests – results of a long-term study in Switzerland) of many unnamed species that suggest that the harvest of fungi either by picking or pulling has no effect on population health [2].
Can you plant your own mushrooms? ›
While foraging for wild mushrooms requires great care, attention and knowledge, growing mushrooms at home can be easy, and a natural extension of vegetable and fruit gardening.
How to germinate mushroom spores? ›
Mix the moist, cool straw with mushroom spawn, such as sawdust spawn. Pack the straw tightly into your prepared bucket or bin and put the lid on it. Put the bucket into another bucket without holes, or wrap the bucket or bin loosely with plastic. Leave it for about a week, so the mycelium can form.
