Mushrooms are an unusual grow-your-own crop that's increasing in popularity. Mushrooms take more effort than most crops to grow, but mushroom growing kits offer easier growing methods, and give you the opportunity to grow ‘gourmet’ varieties such as oyster and shiitake, as well as the more usual button mushrooms.

Mushrooms can be grown indoors or outdoors in prepared beds or boxes, or on hardwood logs outdoors. Indoor growing in a controlled environment usually gives the best results. Outdoors, weather conditions have a strong influence on the success or failure of mushrooms grown in beds, although log-grown mushrooms tend to be more successful.
In this short video guide, the experts at Caley Brothers share their top tips for growing mushrooms, including how much you should water them.
There's a number of ways to grow mushrooms. You can buy mushroom spawn to grow in beds or boxes filled with manure or compost. Alternatively choose a 'mushroom growing kit' that usually includes the spawn and growing media (such as wood shavings or straw). If you have access to recently chopped logs, you can buy wooden dowels or plugs that have been impregnated with spawn, which you tap into pre-drilled holes in the log.
Where to grow mushrooms
Mushrooms are best grown under-cover, where temperature and moisture can be controlled. A shed, garage, garden cold frame or cellar will work well – anywhere out of the sun where it's possible to give mushrooms their optimum growing temperature of around 15°C (the temperature shouldn’t go below 10°C or above 20°C). Outside, grow mushrooms in beds, on compost heaps, or in logs, again away from sunlight.

Growing mushrooms in beds or boxes
A rich, fertile, moisture-retentive growing medium is needed for mushrooms. The traditional material for growing mushrooms is horse manure and you can buy this from your local garden centre or nearby stables. If the manure is fresh, pile it into a heap and fork it over to mix well every couple of days for a fortnight until the heap has cooled and settled.
Ensure the growing medium is moist. Spread the spawn across the surface and mix it 5-8cm deep, then cover with damp newspaper. After several weeks when white thread-like mycelium has appeared, take off the newspaper and cover the mycelium with a 2-3cm layer made up of 50 per cent garden soil or compost mixed with 50 per cent lime. Water as required to keep this evenly moist, using either a hose fitted with a spray attachment, or a watering can fitted with a fine rose. Mushrooms should start appearing from several weeks after sowing.
Growing mushrooms on logs is easy as the logs need little attention once the dowels are inserted. However, you do need to supply and drill your own logs. These need to be hardwood, not conifers, and cut from healthy wood. Logs need to be freshly cut and the dowels implanted no more than six weeks after cutting. The best woods to use are oak, beech, hornbeam, chestnut, hazel, birch, maple or holly. Logs should have a diameter of 10-15cm and be 45-60cm long.
Drill holes along the length of the log, 15cm apart and in rows 8cm apart. Insert the impregnated dowels fully into each hole. Some kits come with sealing wax, so seal each one with wax if directed to. Place the log in a shady spot, under trees or shrubs, with one end on the ground and the other propped up, and ensure it stays moist. Mushrooms can take up to 18 months to appear.
How to grow oyster mushrooms
Buy a pack of oyster mushroom spawn, along with some straw. Soak the straw in water overnight to make sure it's thoroughly damp, discarding excess water. Mix the mushroom spawn with the damp straw and then pack into a polythene bag such as a bin liner. Seal and leave for six weeks in a damp, sheltered spot between 20-25ºC, such as near your compost heap. As the straw breaks down, the mushroom spawn will grow into it, colonising the straw.
Here, Monty Don demonstrates how to grow oyster mushrooms in straw:
After six weeks the oyster mushroom spores will have colonised the straw in the plastic bag. Move the bags into a light, warm and moist environment, such as your greenhouse. Cut slits in the bag so the oyster mushrooms can grow through them.
Monty Don checks on the progress of his oyster mushrooms:
After two weeks, check the bag to see if oyster mushrooms have developed. The straw should continue to produce mushrooms for several weeks.

Advice on buying mushrooms
Mushroom spawn and dowels are available by mail order from specialist mushroom suppliers and from some vegetable seed suppliers
Make sure you buy the right mushroom kit for your needs and space. Success depends on providing the perfect conditions for your mushrooms to grow
Looking for inspiration on how to use your crop? Our friends at olive have curated a delicious collection of mushroom recipes, including a creamy mushroom risotto.
You have to first get a greenhouse, with no windows(lights are usually fine). Then place trays in the greenhouse and fill them with sterilized mushroom substrate that mimics what the fungus grows in. Make sure it is damp, and the room is humid, then spread spores and spawn for the type of mushroom you want to grow.

Another easy, inexpensive option for growing mushrooms at home is inoculated sawdust in a plastic bag. These come in kit versions, but you can also make them yourself. Store them in a bathroom where it is dark and moist and you'll start to see flushing pretty quickly.
This cycle repeats itself in a rhythmic fashion, and harvesting can go on as long as mushrooms continue to mature. Most mushroom farmers harvest for 35 to 42 days, although some harvest a crop for 60 days, and harvest can go on for as long as 150 days.
A: Yes, growing your own mushrooms can save you money in the long run. Mushrooms bought from the store can be expensive, especially if you consume them regularly.
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.
You can absolutely grow mushrooms without a kit! It's definitely more hands-on, but you'll also harvest more mushrooms. To get started, you'll need a bucket, substrate (growing medium), powdered lime, and mushroom spawn.
Buying mushrooms at the grocery store can be expensive, especially if you're looking for gourmet or exotic varieties. However, growing your own mushrooms at home can be a cost-effective way to enjoy these delicacies.
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.
If you're a beginner looking to grow mushrooms at home, oyster mushrooms are the best option for you. There are many varieties available, including pearl, king, and eye-catching pink, blue, and golden oysters.
Some of the mushrooms considered best for human health include chaga, lion's mane, reishi, turkey tail, shiitake, cordyceps and maitake. Often considered vegetables, mushrooms are neither plants nor animals. They belong to a unique kingdom of fungi.

Most mushrooms we make beds with are perennial in temperate climates, meaning they'll continue to grow year after year despite snowfall. This includes wine caps and most of our oyster mushrooms.
But don't even think about eating them. Snap them off, preferably with gloves or a bag on your hands. Otherwise, make a point of washing your hands immediately. Many types of mushrooms can cause damage to humans and pets in many ways.

Can I grow mushrooms at home? Yes.Though it depends on what type of mushroom you want to grow and how much dedication you have. The growing conditions for mushrooms can vary widely from species to species, and some aren't really viable at a small scale.
Most states differentiate between "Intentionally Cultivated" and "Wild Harvested" Mushrooms for regulatory purposes. Generally, simply selling mushrooms you grow in a designated space as a fresh produce item means you can sell with little or no regulation, at least a smaller scale.
Yes, you can grow mushrooms from cuttings, and while you can use any fleshy part of a mushroom for some cloning methods, the best cutting to use is the base of the stem or stem butt. The best stem butt to use is a fresh one with some substrate and mycelium still attached.
