Coco Coir vs Peat Moss
By Katherine Placzek
Dear reader,
This article began initially with a straightforward trajectory. I was going to lay out why using peat moss in soil mixes is environmentally harmful and that we all should make the switch to using coco coir. But as I continued my research, I found it was not that simple and the subject required lots of continued digging to find accurate information. Instead, I am going to try to educate you on both substrates to the best of my ability.
Peat Moss:
Why is it used:
Peat moss has an incredible water retention capability- holding 20 times its weight in water. It also has a small but not insignificant amount of nutrients. You can pot a plant directly in peat moss and it will grow due to these nutrients. It is light and fluffy, used by many gardeners to lighten existing soils. It is highly acidic if not amended with lime, and shrubs like hydrangeas or blueberries can successfully be planted into peat. It also can be used as a pea/bean inoculant. It was not until the 1970s that peat became commonplace as a planting substrate for plant people.
How is it harvested/manufactured:
Peat bogs have centuries (possibly more) worth of plants and decomposing peat/sphagnum peat growing and compacting in a dynamic cycle and ecosystem. It is estimated that peat bogs contain more than 44% of all the Earth’s soil carbon and thus are considered a carbon sink (where carbon is stored and absorbed from the atmosphere). Harvesting practices vary in different bogs and countries. The majority of the peat sold in the United States is harvested in Canada. 95% of all peat in Canada is harvested in partnership with the Canadian Sphagnum Peat Moss Association (CSPMA). The CSPMA has strict regulations that they follow, and are involved in many ecological restorations, as well as scientific research behind peat bogs, and the living organisms that use the bogs as habitat. Many of their practices publicize that they attempt to reduce harm, prevent overharvesting, protect habitats, and replant as part of their aim toward sustainability. While this sounds good, in 2021, it was reported that peat harvesting released 2.1 megatonnes of carbon dioxide into the environment. That’s the equivalent emissions of the annual emissions of five gas-fired power plants. Critics also point out that rehabilitated peat bogs are unable to become a carbon-accumulating ecosystem (or a carbon sink) until roughly 20 years after harvesting. Harvesting in other countries is not regulated and they are likely not as concerned with any harm associated with their practices. All harvesting is mechanical due to utilizing fossil fuels. The UK has banned all peat sales for personal gardens beginning in 2024.
Factors to consider:
- Peat bogs house diverse and intricate habitats for all sorts of living organisms. Harvesting, regardless of practice, disrupts this environment.
- Peat bogs are considered carbon sinks- absorbing carbon from the atmosphere. Harvesting peat releases carbon into the atmosphere, causing concern that this practice contributes to climate change.
- Fossil fuels are used in the harvesting process and are used in the shipping of this product to garden centers and other plant/ home improvement stores.
Coco Coir:
Why is it used:
Coco Coir also has a high water retention rate, retaining 8-9 times its weight in water. It does not have any innate nutrients or pH implications, so it is a neutral starting point as a substrate. Coco coir is a waste product from all other food-grade products made from the meat/ milk of the coconut. Before the 1980s, millions of tons of coco coir were left to decompose in large piles, often taking close to 20 years to decompose. Now there is a market for this “waste product,” as a soil substrate.
How is it harvested/manufactured:
Many coconut plantations are based in the poorest countries, Sri Lanka, India, Vietnam, the Philippines, and more recently, in Central and South America and even Mexico. Coconut plantations are often monocultures that reduce natural biodiversity and cause displacement of living organisms. Coconut trees produce a lot of coconuts but do so at the cost of soil degradation. The coconut hull first is soaked in water (freshwater or saltwater) for a long time to break down the fibers on the hull. This process is called retting. The retting process generates water pollution. Among the major organic pollutants are pectin, fat, tannin, toxic polyphenols, and several types of bacteria including salmonella. While scientists are experimenting with treatment options, there does not seem to be a broad-scale accepted solution at this time. This wastewater is often returned to the local community’s water supply or the ocean. Then, either the coconut hulls can be highly processed through mechanical mastication, or beaten and broken down further by hand. This manual process creates a lot of dust, and workers are typically not provided any PPE (Personal Protective Equipment). Reports indicate an increase in respiratory illnesses in communities with coco coir processing. Many of the following processes, if mechanized, are achieved with fossil fuels. There are currently no regulations on the industry’s standards. I also found conflicting information on whether a second rinse with chemicals is necessary, so that is an additional set of pollution outputs to consider. In general, it’s harder to find reputable sources explicitly sharing information about coco coir. This makes me concerned about the transparency of the industry, as well as possible offenses that are intentionally hidden from the public’s knowledge.
Factors to consider:
- Many coconut plantations are monocultures, created by destroying native habitats for diverse organisms, thus causing soil degradation.
- Pollution of the environment due to wastewater from retting processes.
- The lack of regulations concerning this product allows for humanitarian abuses to occur, including health hazards for workers and the surrounding community.
- Fossil fuels are used in portions of the manufacturing process and in transporting this product to your local garden center.
I think continuing to use coco coir or peat moss warrants extra research. Dig into the companies that you are supporting. Do they have certifications, and third-party ratings that indicate that they care about their staff’s health and wellbeing? The environment and the community they impact? Their carbon footprint? Other points that you are passionate about?
All of this makes me consider, there have been gardeners and plants people before me who did not have access to these substrates. What did they use before? Compost. Manure. Leaves. Green manures/ cover crops. Aged forest products (humus). Straw. None of these probably have the water retention that peat moss or coco coir boast, but they all have higher nutrition, which means prior plants people did not have to fertilize in the same manner that we do when we utilize a peat or coco coir base. Many of these local inputs are also free. All of this is interesting and will lead to further research on my part.
The most honest conclusion that I can make is that, when we are removed from the product we are buying, we also become naïve of the ultimate cost and any negative impacts of the product. Perhaps, the point here is to grow plants that are acclimated to our growing habitat (for instance, native plants do not need peat or coco coir to thrive), or to build soil from what nature provides in our local vicinity. While this is easy to say, it is harder to do. I think this new knowledge is powerful, though. We can always experiment and try new things in hopes of finding replacements that have a lesser negative impact. Good luck with your own decisions ahead of you!

Blossoms on Your Plate
Are you ready to elevate your gardening game to a whole new level of deliciousness? Well, we’re about to dive into the vibrant world of edible flowers that will not only make your garden pop but also your plate! Many of them are easy to grow, forgiving of rookie mistakes, and will reward you with an explosion of colors and flavors.
Nasturtiums (Tropaeolum majus): These deep burgundy to buttery yellow blooms have a peppery kick, perfect as a spicy twist to salads, tacos, and avocado toasts. Bonus: They’re easy to grow, thriving in poor soil and other neglect. These flowers are high in vitamin C. The entire plant is edible- so try out the lily pad-like leaves also! Deer resistant.
Calendula (Calendula officinalis): Often called “poor man’s saffron,” the golden petals of calendula add a subtle saffron flavor to rice dishes and soups. They’re sun lovers and can tough it out in the Rocky Mountain soil. This flower is also known for its skin-healing properties, consider making a toner with calendula flowers. Deer are typically not a fan of these flowers.
Pansies (Viola tricolor): These adorable flowers come in an array of colors and have a slightly sweet, grassy taste. Scatter them over desserts after dipping them in water and then sugar for a delicate but sweet touch. Or freeze them in ice cubes for fancy drinks. Pansies are cold-hardy and can withstand our unpredictable mountain weather. We had a pot of pansies survive the entire winter, even when temperatures dipped below 20 degrees!
Lavender (Lavandula angustifolia): Known for its calming aroma, lavender adds a delicate floral flavor to desserts, teas, and even cocktails. It thrives in well-drained soil, making it a great match for rocky gardens. We have several varieties that will survive year-round in our nursery area. Look for varieties such as Munstead, Hidot Blue, and Phenomenal. Due to the fragrance of these flowers, deer typically leave them alone.
Rose (Rosa spp.): Beyond being a symbol of romance, roses can be used in various culinary creations. Make tea with their dried petals, infuse honey with their fragrance, or toss the petals into desserts. The rose hips that are produced in the fall are also edible and high in vitamin C. You can make tea from the rosehips as well. We have several varieties of roses, some more bred for their blooms, others are cultivated to be hardy for our mountainous climate.
Borage (Borago officinalis): With its brilliant blue flowers, borage adds a refreshing cucumber taste to salads, drinks, and desserts. The best part? Borage is a self-seeding annual, making it a low-maintenance addition to your garden. The pollinators will also feast on these blooms! Deer typically avoid this plant.
Chamomile (Matricaria chamomilla): Beyond being a bedtime tea, chamomile flowers can be used in salads or infused into syrups that go well in cocktails, over ice cream, or on pancakes. These sun-loving plants will thrive in our bright sun. Deer tend to avoid this plant due to its fragrance.
Dianthus (Dianthus spp.): Also known as pinks, or sometimes recognized as carnations, these flowers have a mild clove-like flavor. Add them to fruit salads, and desserts, or dry them and add them to various spice blends (za’atar, is a great example). Dianthus are hardy perennials, returning year after year. They are also deer-resistant.
Hibiscus (Hibiscus rosa-sinensis): Hibiscus flowers make a delightful and tropical addition to beverages, jams, and desserts. We carry gorgeous hardy hibiscus that will winter as a perennial shrub. Hibiscus also has high levels of vitamin C and is an excellent herb for overall health.
Daylilies (Hemerocallis spp.): Despite their fleeting beauty, daylilies are edible and offer a slightly sweet flavor. Stuff the blossoms with a soft cheese, or add them to stir-fries. Do your research on whether you have a daylily, before digging into a meal. Not all species of lilies are edible. These hardy perennials are a reliable choice in our climate.
Elderflower (Sambucus nigra): Fragrant elderflowers can be used to make refreshing beverages like elderflower cordial or add a subtle floral note to desserts. Elderflowers come from elderberry bushes, so you will also be able to eat elderberries if the birds don’t beat you to it! These shrubs are well-suited for the mountain environment, making them a great choice for your garden.
So, whether you’re a seasoned horticulturist or a budding green thumb, dive into the world of edible flowers and turn your garden into a culinary masterpiece. After all, why just stop and smell the roses when you can toss them in a dish too? Happy gardening and bon appétit!
Bare Root Fruit Trees
What are bare root trees?
Bare root trees are harvested from their growing beds in the late fall, and the soil is removed from their roots. They are kept in cold storage over the winter, and planted before they break dormancy in the spring.
What are the advantages of planting bare root trees?
Improved Tree Health
Bare root trees are not grown in a container. This eliminates the industry-wide problems of circling and girdling roots that develop in container-grown stock, a major threat to even healthy-looking plants. Also, since bare root trees are planted early in the spring before they leaf out, the trees get a head start on developing strong root systems in the native soil before they start producing leaves, flowers, and fruit.
Light Weight & Reduced Environmental Impact
Bare root trees are much lighter when shipped. This saves on freight and fuel and makes them easier to maneuver while planting.
More Cost Effective
Shipping bare root trees is much less expensive, and that savings is passed directly to the customer. Our trees will be comparable in size to a #5 container tree, but for half the price! (All trees will be a minimum of 5/8th inch caliper.)
We are excited to offer bare root fruit trees at Rick’s this spring! We are working hard to bring you the best fruit trees possible.
Excellent Quality
The bare root fruit trees we are selling will be of superior quality! We chose to source these trees specifically from growers who supply professional orchardists. Van Well Nursery is based in Washington state and works with several orchards in the Palisade, Colorado area. They have an excellent reputation among professional growers, and we’re excited to offer that level of quality in Colorado Springs! We have consulted with Van Well to bring you the best in bare root fruit trees for our local climate.
Exceptional Rootstock
Since their seed is not true to type, fruit trees are produced from cuttings. Many species of apples, pears, and plums do not root easily from cuttings, so they are grafted onto rootstock grown specifically for this purpose, a practice dating back over 2,000 years.
When purchasing any fruit tree, it is important to inquire about the quality of the rootstock. For our bare root trees, all apples are grafted onto EMLA 7 rootstock. This rootstock is semi-dwarfing, meaning each variety will grow about 50-60% smaller than typical, which is perfect for backyard orchards. This rootstock was chosen for its cold hardiness and extreme resistance to fireblight. The plums are grafted onto a peach seedling rootstock.
Interesting Varieties
This year, Rick’s will have eight kinds of apples and two kinds of plums to choose from. We will have heritage apples like Macoun and Yellow Newton, and some new arrivals like Ambrosia and Gale Gala. We even have an apple variety that’s used for cider, Yarlington Mill, which arose from a chance seedling discovered in 1898! The plum varieties are both European plums and are very cold hardy.
It should be noted that all apples need another apple (or fruit-bearing crabapple) of a different variety to cross-pollinate. Both types of plums that we carry are semi self-fruitful, but they will bear a heavier crop with a different plum cultivar nearby to cross-pollinate. The two plum varieties we will be carrying will cross-pollinate with each other very nicely. For fruit trees to cross-pollinate, they should be planted within 100 feet of each other.
Cost and Availability
Each bare root tree will be $39.99 and will be sold on a first come, first served basis.
The trees will be arriving in early March, weather permitting. We will continue to sell the bare root trees until they start to break bud, most likely in early April.
If you would like to be notified when the bare root trees become available, please email us at info@ricksgarden.com or call the store at (719) 632-8491 to be put on our notification list.
Timing and Handling
Timing is important when purchasing and planting bare root fruit trees. Bare root trees can only be planted in the early spring. Bare root trees that are planted after they leaf out have a much lower survival rate.
Proper handling is crucial for bare root stock. Roots should never be allowed to dry out – even five minutes of sun exposure on a warm day can do life-threatening damage to the tree. When you purchase a bare root tree from Rick’s, you will be provided with a burlap sack and wet mulch (or other means) to protect the roots during transportation.
The tree should be planted as soon as you get home from the nursery. If you will not be able to plant the tree immediately, please talk to our nursery staff so they can advise you on proper storage procedures.
Planting
Planting bare root trees is very similar to planting trees that have been grown in containers. The most important thing is to not plant too deep; you should have a structural root within the first one to two inches of soil. Amend soil to a maximum ratio of one part compost to four parts native soil. Cover the planting area with three inches of mulch, taking care to not contact the trunk. Staking may be necessary depending on root spread, soil type, and wind exposure.
Protection
Young trees that are small in diameter are the perfect size for deer to rub their antlers on. If deer graze in your neighborhood, cage trees immediately after planting. Trees left unprotected for even one night can be terminally damaged by deer.

Fall Perennial Planting
Planting in the fall can save you a lot of money while also giving plants a jump start next spring! Plants that establish strong roots during the fall will come back bigger and stronger in the spring time.
However, fall planting requires careful consideration and attention to detail from the gardener. The trick is to give fall plantings a little extra care to help them get established before the really cold weather sets in.
Here are four things you can do to help your plants get established:
Soil Inoculant
At the time of planting, be sure to use an inoculant specifically formulated for perennials, trees and shrubs. These products will help the plant to start establishing roots before all of the foliage dies back. We recommend using an inoculant over a root stimulator this late in the season so you can avoid giving any extra nitrogen to the plant before it goes in to dormancy.
Mulch
Mulch helps to retain soil moisture while also protecting roots from sudden changes in temperature. We recommend using 3″ of a good quality mulch to keep plants protected. Make sure that mulch does not contact the bark of woody perennials.
Protect Plants from Early Freezes
Keep an eye on the weather and cover the plants when the temperatures dip below freezing throughout September and October. This is most important for perennials. Trees do not need to be blanketed, but bark wrap should be used on all young trees to protect the trunks from splitting during our freezing and thawing cycles. When covering perennials, use heavy fabric or plastic and prop it up so that it is close to, but does not touch the plant (Plastic that touches the plant during a freeze can actually do more damage.) Be sure the covering goes all the way to the ground and cover the edges with soil or mulch so that it will trap heat from the soil.
Water
To support adequate root growth, plants will need to be watered regularly in the fall. Keep your soil evenly moist, but not soggy, through the fall time. Remember to monitor your plants regularly! A plant that crisps up due to lack of water in the fall time is not likely to survive the winter. When the plant goes dormant, they will require less frequent watering, but will also need to be watered throughout the winter. Remember that desiccation is the result of cold weather plus dry soil.
