Plants that Don’t Like Mushroom Compost 

Last Updated on March 12, 2022 by Maria B.

Mushroom composting is one of the many composting methods you can adopt to decompose kitchen waste. While you can buy mushroom compost to use as a conditioner for your soil, you need to be aware of the plants that don’t like mushroom compost. 

In this article, we will be talking about mushroom compost, the benefits of using it and where to use it. 

What is Mushroom Compost?

Mushroom compost is also referred to as spent mushroom compost since it obtained from the remains of mushroom farming. It is mainly used as a mulch and soil conditioner to improve ornamental and vegetable garden. Due to its alkalinity, it is wrong to use mushroom compost for acid-loving (ericaceous) plants. 

Most gardeners use mushroom compost to improve moisture content of their soil and in breaking down clay. But what most of them don’t know is that there are different types of mushroom compost. The most commercially available type is the mushroom substrate that is usually a mix of chicken or horse manure and gypsum or wheat straw. In large scale production of substrates, large bales of wheat straws are dipped in water and then cut into pieces by the help of a chipper. After which the straw is gradually worked into the gypsum and manure. After the materials are composted, they are sterilized to improve the quality before they are taken to the growing trays. 

Another type is the spent mushroom compost which is what’s obtained from mushrooms farms. They are often sold as conditioners for turfs and lawns where it is used to improve the soil quality. They are equally useful in raised bed mediums and planting mix where it helps to improve water retention. 

How to Use Mushroom Compost?

Mushroom compost has a versatile application. For starters, you can easily add it to any soil to improve the quality before the commencement of planting season. They are mostly suitable for use on vegetable gardens but are equally effective in most alkaline soil. Before you lay your lawn grass, it is best that you work the mushroom compost into the soil. You should apply up to 3-inch of mushroom compost on top of your annual or perennial bed and dig to 6-inch depth to get the best results. Do not forget to water your lawn regularly and be on the watch out for weeds.

Once you apply mushroom compost to your lawn, there is no need for any additional fertilizer or herbicides for the entire season. To prevent your plant root from burning out, it is best that you apply your mushroom compost close to the stems of your plant for easy nutrient uptake. 

You will likely be dealing with weeds when you use compost in your garden, and shouldn’t be worried when you find some on top of your mushroom compost. But when they are properly sterilized before storage, you barely have to worry about weeds. 

Mushroom compost can also be used on house plants, but it is important that you apply only a thin layer on top of the potting soil. You also want to check that there are enough drainage holes in your pot. Flowers pots without drainage are not suitable for mushroom compost or any other type of compost. 

Are there Chemical Residues in Mushroom Compost?

They are claims that mushroom compost contains chemical residues for the industries and might not be suitable for use. It is okay to be conscious on what you feed your plants and plant soil. But the truth is that you cannot be certain about what really goes on in those mushroom farms. 

Most mushroom farmers make use of chemical sprays to tackle the problems of flies and gnats in their facilities. These chemical sprays may get into the mushroom compost making it unfit to be used in certified organic farms. Some of the common chemicals used in the mushroom farms to tackle insect problems include methoprene, diazinon, dimlin, cyromazine, and diflubenzuron. They also apply chemicals such as chlorothalonil, benomyl, and thiabendazole to treat fungal infections in mushroom crops. 

When looking to get mushroom compost from farms, is recommended that you enquire about the type of chemicals used in growing the plants. This makes it possible for you to know whether or not the compost will contain toxic materials. The presence of toxic chemicals in your mushroom compost can make it difficult for it to take effect on your plants. 

Plants that Don’t like Mushroom Compost

Like we mentioned earlier, mushroom compost is not a good fit for ericaceous plants. These are plants that grow in acidic or infertile soil conditions. For these plants, you will want to apply acidic compost that has slightly higher nitrogen content. Mushroom compost can be added to plants with a slightly higher alkaline content. Some examples of the plants that don’t like mushroom compost include:

  • Camellia 
  • Cranberry 
  • Viburnum 
  • Gardenia 
  • Hydrangea 
  • Azalea 
  • Blueberry 
  • Rhododendron 
  • Magnolia 
  • Japanese maple 
  • Aster 
  • Fern 
  • Juniper 
  • Lupine 
  • Holly 
  • Bleeding heart

What vegetable plants do not like mushroom compost?

If you have never used mushroom compost in your garden before, you might be wondering what vegetable plants do not like it. Compost is an organic fertilizer that has been used for hundreds of years to enrich soil and boost plant growth. It can be made from many different sources including kitchen waste, yard waste, leaves and even manure. In fact, composting is a great way to get rid of all those food scraps and household waste that would otherwise end up in a landfill.

Compost is often referred to as “black gold” because of its high nutrient value. In addition to being rich in nutrients, compost also provides a safe place for bacteria and fungi to grow. These organisms decompose the organic material in your compost and turn it into humus, which is the most stable form of organic matter. Humus helps your plants absorb nutrients from the soil. By adding mushroom compost to your garden, you are making it easier for your plants to absorb the nutrients they need. There are some vegetables, however, that do not like the smell or taste of compost. If your compost smells bad or tastes bitter, it can cause your plants to have a hard time absorbing the nutrients they need. You can avoid this problem by using an odor neutralizer and adding an ingredient to your compost to mask the bitter taste. You can also choose to use a different composting method, such as the worm composting method.

Is mushroom compost good for all plants?

Mushroom compost is a valuable addition to any garden. IIt's best to use mushroom compost in the spring or fall when you're planning to plant a new crop. The mushroom compost has a low nitrogen content and will help the soil warm up and prepare for the new plant. It also contains natural nutrients that help boost the growth of the new crop.

There are two types of mushroom compost available, bagged and bulk. I'd recommend using bagged compost because it's easy to add to your garden and will be ready for use once you're ready to plant. Bagged compost can be added to your garden once a week, or whenever you want to add it. Bulk compost must be mixed into your soil to be effective. Bagged mushroom compost is available in four different sizes: 1-gal., 2-gal., 4-gal., and 6-gal. Bulk mushroom compost is available in several sizes, but I don't recommend buying it in bulk. If you purchase bulk mushroom compost, it will be very difficult to mix it into your soil. You may have to mix it with a shovel or by hand.

Is mushroom compost better than regular compost?

Mushroom compost has a higher nitrogen content than regular compost. Mushroom compost is more efficient in converting organic matter into nutrients for the plants it supports.

 Mushrooms can also add beneficial enzymes to your compost. Composting with mushrooms can be done right away or you can wait until the mushrooms have fully colonized the compost. There is no hard and fast rule. It will depend on the type of mushrooms you use and the conditions of your bin. If your bin is too hot, or if the mushrooms are not growing as well as you would like, you may want to wait. If you are going to use the compost in your garden within a few months, wait.
