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.

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.

One of the benefits of growing your mushroom varieties instead of wild-harvesting them is that you can be sure you're not picking a toxic mushroom. Cremini, enoki, maitake, portobello, oyster, shiitake, and white button mushrooms can all be grown indoors, but each type has specific growing needs.
The six steps are Phase I composting, Phase II composting, spawning, casing, pinning, and cropping. These steps are described in their naturally occurring sequence, emphasizing the salient features within each step. Compost provides nutrients needed for mushrooms to grow.
Mushrooms require less growing materials, water, and energy than other types of crops. There are many reasons why mushroom agriculture is more sustainable than other types of agriculture, which start with the growing process.
The easiest, cheapest, and most accessible method is the "popcorn tek" (see here for more info: http://www.shroomery.org/9035/Popcorn-Tek-w-pics) You can also use rye berries or something else but let's just keep it simple and focus on the popcorn for this.

Unlike plants that rely heavily on direct sunlight for photosynthesis, mushrooms do not require direct sunlight. In fact, excessive exposure to direct sunlight or full sun can be detrimental to their development. The ideal lighting condition for mushrooms is often described as mimicking natural daylight.
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.
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.
Oyster mushrooms (Pleurotus ostreatus) or Shiitake mushrooms (Lentinula edodes) are great choices for first timers because they are delicious and are some of the easiest to grow. How you grow your mushrooms will depend on the kit you buy. But don't worry; they should come with instructions to help you get started.

On average, one square foot of space in a mushroom bed can produce 6.55 pounds of mushrooms. One square foot is 144 square inches, or 4.5 red bricks in a patio– that's a lot of production power in a small space. One acre of land can produce 1 million pounds of mushrooms annually.
