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.

Can I grow mushrooms from a store-bought mushroom? ›
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.
How to 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.
Can 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 trigger mushroom growth? ›
Fresh air, humidity, light, and temperature are the four main environmental variables that trigger fruiting from fully colonized substrates.
What is the easiest way to grow mushrooms for beginners? ›
Spray-and-grow kits, a block of colonized substrate inside a small box, make for the easiest way for beginners to get started. “They're inexpensive. You get a lot of mushrooms out of them. And they're super easy,” says Lynch.
How to grow mushrooms in coffee grounds? ›
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.
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.
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 get 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.
Most mushrooms found at grocery stores, such as white, button, and cremini, are grown in indoor farms with pre-treated compost to reduce bacteria levels, and they often come packed pretty clean. A damp paper towel to clean these mushrooms should do the trick.
How many mushrooms can you grow from a kit? ›
Expect to grow: 2-3 harvests of mushrooms / 150g - 300g
The first flush will always be the biggest. We've had some customers grow up to 4 flushes of mushrooms from our kits but on average you'll get 2 harvests. Once the kit has run out of nutrients and water it will be "spent" and won't produce any more mushrooms.
How to encourage mushroom growth? ›
Placing the bale in the shade, using shade cloth, or inoculating with sawdust spawn can keep your mushroom bale growing well as temperatures rise.
Can you grow mushrooms from mushroom stalks? ›
Button mushrooms, chestnut mushrooms, portobello mushrooms, and maybe even some fancy shiitake mushrooms if you're lucky. Thankfully, it's possible to grow all of these mushrooms from scraps. 'The stems retain mycelium, which can be cultivated to grow new mushrooms,' explains Calum Maddock at HomeHow.
Do you need to cut the ends of mushrooms? ›
No matter what shape you want, the key is to first trim off the stem of your shrooms. This not only removes any woody, dried out, or dirty sections, but more importantly it also creates a flat base for your mushroom to rest on, making slicing much easier and safer.
Can you grow mushrooms from spore prints? ›
A spore grows into a single mushroom, and one mushroom can produce hundreds of thousands of spores. Spore prints, in addition to being used for identification of wild mushrooms, can also be used to cultivate mushrooms. The dry spores on the print must be hydrated for use.
How do you propagate mushrooms from mycelium? ›
Again, in an extremely clean environment, cut a sample of mycelium and transfer it into a jar of sterilized grain. The mushroom mycelium will start to grow out, running across and devouring the grain, eventually taking over the whole jar.
