Protecting Our Watershed While Gardening & Landscaping
By Katherine Placzek
Every item that we use in our green spaces– fertilizers, pesticides, sprays, powders and granules, etc. all make their way into the water, after it rains or when we water our plants. This means a myriad of compounds, organic and synthetic, are making their way in our or someone’s drinking water. Yes, most of our drinking water is filtered, but this also impacts lakes, streams, aquifers, wells, and other sources of water that can be a habitat for other living organisms, big and small. While this may feel overwhelming initially, we have the power to make little meaningful changes in the way we manage our landscapes.
Lawn and Garden Fertilization
Three things make a difference here. Quantity, quality and timing:
Quantity: When you use fertilizer, always use the instructed amount of fertilizer or a diluted/ lesser amount. This ensures that your plants can take up the applied fertilizer and that excess is not making its way into our waterways. Excess fertilization can stress plants and negatively impact water quality. Over fertilizer use through agriculture, golf course maintenance, and community landscaping have contributed to dead zones in waterways. A dead zone is where all aquatic life ceases to exist. First, expansive algae blooms occur that crowd out sunlight, which choke oxygen out of the environment, causing inhabitable levels for any life, plant or animal. While some dead zones do occur naturally, the second largest one in the world is in the Gulf of Mexico, where many of North America’s waterways meet. This dead zone is widely attributed to human causes.
Quality: When choosing a fertilizer, it is advisable to read the ingredients, similar to reading food labels. If you cannot recognize an ingredient, know it is likely synthetic. Not all things that are human made are bad, but do your research. You may decide that you do not want some of these ingredients in your garage, home, yard, and local ecosystem. This is why Rick’s is proud to continue to carry our Organic Lawn and Garden fertilizers. Both of these are gentle fertilizers, with low nitrogen levels, and contain ingredients such as chicken manure, bone meal and blood meal.
Timing: Never fertilize before a severe rainstorm where run-off can take the majority of your fertilizer downstream. This is also cost prohibitive. If you plan on putting fertilizer down before predicted moisture, consider prior to a snowfall, where the melting snow can bring the fertilizer into the ground gently. Also read the instructions. Many fertilizers recommend a fertilizing schedule. Follow this, or see if you can stretch the schedule out further, to reduce the amount of fertilizer that you have to buy and apply throughout the year. Never fertilize more than what is recommended, this can stress the plant, and excess product will be absorbed into the waterways.
Pesticide Use
Pesticides include insecticides, herbicides, and fungicides. Similar to fertilizing, follow the same wisdom regarding quantity, quality and timing. We have said it before, but just to remind you: “While pesticides are convenient and sometimes necessary especially when mitigating invasive plant species, pesticides negatively impact pollinator numbers…. It is important to remember that while applying control products at night can reduce pesticide exposure to several pollinators/ beneficial species, this does not protect nocturnal pollinators such as moths and bats. When we use pesticides there is no current method that does not negatively affect pollinators or their second tier predators, who are further up the food chain (Excerpt from our March 2024 newsletter).” All of these pesticides reach water sources that are drinking water for pollinators and larger organisms: birds, fish, fox, deer, etc. Many of the chemicals used in popular pesticides, including glyphosate do not break down with water. This means the problem is washed downstream, but never away, and can exist in our waterways indefinitely. Manual removal of weeds is no fun- we all know this. When we choose conventional pesticides, we give up clean water. Limiting the amount of pesticides we use in our yards is one step to keeping our watershed less polluted.
General Maintenance
When you mow your lawn, consider mulching the cut grass instead of bagging it unless you use the cut grass in your compost. Mulched grass that has been chopped by the mower multiple times and is spread evenly over the lawn acts as a wonderful additive of organic material to the soil. This method improves water retention, and overall soil health, decreasing your need for fertilizer. If you mulch the cut grass, but leave large clumps of thatch, this can burn your grass and be swept away into a waterway. This process can act similarly to over fertilization, causing algae blooms downstream. Use the same logic with fall leaves. Mulch leaf litter and either use it on your lawn or in your garden, to add nutrition to the soil. Avoid abandoning leaves in gutters, and storm drains, as it increases excess nitrogen in the watershed. In the winter, make sure you are using a low saline and non-toxic ice melt as well. Water guardianship takes place in all four seasons!
Plant Selection
Finally, the fun stuff! Select plants and grasses for your landscape that are resilient to the Rocky Mountain circumstances. When we do this, we automatically reduce the need for mowing, fertilizing and the use of pesticides. Native plants especially, have been living here in the Colorado landscape much longer than any human lifespan. They have been taking care of themselves without any of our human care measures, such as fertilization, and will continue to do so into the future. I believe that by choosing to plant native plants in a landscape, you are actually simplifying your overall workload in the yard. You will fertilize less, you will use pesticides less, and regarding grass, you will mow less. That means more money in your pocket and more sitting on the back porch, sipping on a cold beverage. Cheers!
The Gothic Vegetable Garden
By Katherine Placzek
Black & purple vegetables are not only for someone who is looking for a fun or Gothic vibe in their garden. Purple-ish fruits and vegetables have higher antioxidants, which play an important role in protecting your cells against heart disease, cancer, and other diseases. So it is healthy for you to plant and eat these dark maroon beauties!
All of these vegetables are carried by us as seeds through the Botanical Interests or Lake Valley Seed brands (both CO businesses). There is a wide array of purple/ black vegetables so feel free to go down the rabbit hole and create the dark and mysterious garden of your dreams! Note that various seeds may be out of stock throughout the season.
Amaranth
Burgundy: These plants offer beauty and sustenance! The plants can get tall and have elegant and eye-catching burgundy plumes that can be used in flower arrangements. The seeds were a major crop of the Aztecs, and are very high in protein and other nutrients. Cook the beige seeds like rice. Young leaves are also edible- use them in salads or steamed. The birds will also enjoy the seeds!
Basil
Cardinal: Cardinal’s’ deep crimson blooms allow this basil variety to be utilized beyond its culinary qualities! Use it as a surprising accent in a mixed container, or use it as a cut flower! The fragrance is lovely. With its strong scent, a little goes a long way in the kitchen. A wonderful dual-purpose herb.

It is easy to grow and highly ornamental with its dark amethyst blooms. Flower farms also grow Thai basil, for cut bouquets. Include it in your garden flower bunch and enjoy the unique fragrance. Bees also love this stuff!
Sweet Thai: Thai basil is of course a popular herb in many Southeast Asian cuisines, and is most regularly highlighted in a warm bowl of Vietnamese pho. This variety holds its flavor and texture through cooking more than other basils. Lovely in salads or when eaten fresh. Sweet Thai’s dark purple flowers and intoxicating scent allow it to double as an excellent addition to the flower garden. Produces well in containers also.
Beans
Royal Burgundy (Bush): Royal Burgundy has yummy purple pods that are easy to spot among green leaves. A wonderful variety to grow in cool weather and is unlikely to be challenged by bean beetles. A good container variety, as well as disease-resistant.
Trionfo Violetto (Pole): Trionfo Violetto’ translates to “purple triumph.” This Italian heirloom will win your heart, with its crisp and flavorful purple pods. While highly ornamental the plants are also highly prolific! The plants climb 6’–8′, and have prolific light amethyst flowers that bloom against green leaves that sport purple veins and stems. Similar to other purple beans, the pods magically turn green when they are cooked!
Beets
Bulls Blood: Plant one row of this beet variety for the beautiful greens, and another for the flavorful roots! ‘Bull’s Blood’ is valued for its tender, sweet, and deep red– almost plum foliage. Originally selected from a French heirloom for the darkest colored leaves, the 16″ “greens” are rich in nutrients! The roots are delicious as well, especially so, when harvested small. Use in succession planting as multiple crops are possible throughout a season.
Broccoli
Burgundy: This variety of broccoli is considered a “sprouting broccoli” since it produces one small main head, but then produces generous side shoots. Purple broccolis tend to be tender, flavorful, and full of antioxidants! ‘Burgundy’; is tolerant of a wider range of temperatures, which allows a longer harvest period. Some gardeners prefer to pinch the main floret off early on, to encourage more abundant side shoots. Also resistant to the disease, Fusarium yellows.
Cabbage
Red Acre: Jazz up cole slaw or any stir-fry with this gorgeous, deep-fuchsia cabbage! This variety has a very fresh and sweet flavor. Solid heads form early and grow on compact plants making ‘Red Acre’ an ideal choice for urban gardeners who may have limited space. Resistant to splitting as well as cabbage yellows disease. The heads store very well, in the refrigerator or a root cellar. A variety you must try!
Carrots
Cosmic Purple Carrots: While various colored carrots seem to be the new fad, they have been around for centuries. In fact, the purple carrot has been around for at least 1,000 years! While previously unpopular compared to orange carrots, purple carrots have been rediscovered, and rightfully so! Besides being high in vitamin A, purple carrots contain anthocyanins (an antioxidant) that are common in blueberries. Kids will love them!
Eggplants
Black Beauty: A beautiful nearly black vegetable with lovely, lavender blossoms pretty enough to grow in the flower garden! ‘Black Beauty’ has set the standard since 1902 for large and high-quality fruit. When harvested at its peak, the skin is tender, so no need to peel it; making it perfect for eggplant parmesan, ratatouille, and grilling!
Finger Fruit Purple: Grow fast-producing clusters of beautiful eggplants on your patio or a sunny corner of your vegetable plot! These 4-6″ fruits contain few seeds and have thin, tender skin—perfect for stir-fries and roasting. A plethora of royal purple fruits on just 22-38″ tall plants make this variety a perfect fit for containers and small gardens.
Jewel Amethyst: ‘Jewel Amethyst’ is perfect for containers, since it has a tidy habit. You will also notice its growing pattern makes harvesting a joy! The oval, purple fruits are best harvested when about 3”–4 ½” long, to stay tender. Harvest regularly from this variety to keep eggplant producing throughout the season.
Long Purple: This long, slender variety, is not usually found in grocery stores, and is a treat! Sometimes called ‘Italian Long Purple’, this prolific heirloom will bring beautiful ruby-purple color to the garden and savory goodness to the table. Enjoy in a wide variety of dishes!
Kohlrabi
Early Purple Vienna: Early Purple Vienna kohlrabi is an easy-to-grow cool weather crop that forms a distinctive dusty lilac bulb with pale flesh above ground. A beautiful plant! Peel its crunchy bulb and enjoy it raw or cooked. Leaves are also edible- eat similarly to collards, or other steamed greens. Kohlrabi is high in fiber, making it an excellent veggie for overall gut health. Kohlrabi is also high in isothiocyanates and glucosinolates, which are powerful antioxidants, thought to lower the risk of certain cancers, heart disease, and inflammation. Keeps well in the fridge.
Lettuces/ Greens
Brentwood Lettuce: This variety produces pretty burgundy lettuce leaves making for some beautiful salads! The heads produce high yields in compact spaces, and their bolt resistance allows for a long harvest. Also resistant to downy mildew, lettuce leaf aphid, and Fusarium wilt.
Dazzling Blue Kale: You will be mesmerized by the beautiful colors of this extra-cold-hardy kale. It is even more cold-tolerant than other lacinato types. The purple midrib pops against the blue-green leaves, some of which may take on more purple hues in the cool temperatures of fall. Lacinato kale is ideal for kale salads.

This is the most productive red variety and will produce tender, 6″-long pods that are delicious in soup, gumbo, and stew, or deep-fried.
Shiso
Green and Red Shiso Perilla: An absolute must for herb gardens! Also called Japanese basil or the beefsteak plant, shiso’s incredible flavor can be described as a combination of cinnamon, mint, and clove with notes of cumin. A beautiful, heat- and drought-tolerant bedding plant that attracts pollinators, and is excellent for containers. This packet provides 75% green shiso and 25% red (shows up as a deep mulberry color).
Snap Pea
Sugar Magnolia: Wow, a purple snap pea that is tender and delicious! Enjoy the pretty purple blooms first, then the purple pea pods. Eat them without shelling, dipped in hummus, in a salad, or in stir-fries! Long hypertendrils (vigorous, multi-branching tendrils) support the 6′-7′ vining plants. This growing pattern creates an airy structure that helps prevent mildew. Some of these open-pollinated peas may be flecked with green, or be fully green.
Tomatillo
Purple: A purple tomatillo! Not only delicious but alluring also. The purple fruits are much sweeter than the green types and rich in antioxidants. Let the fruit remain on the plant as long as possible until the papery husks split for the best flavor and color. Tomatillos grow best in conditions similar to tomatoes (because they are related) but will handle a lot more heat. Tomatillos require cross-pollination so plant at least two plants in your garden to ensure good fruit production
Tomatoes
Black Krim: This Russian pole heirloom originated in Krymsk on the Black Sea in Russia. Baseball-sized fruits weigh 10–12 ounces and have dark reddish-brown flesh filled with a rich, slightly savory flavor. Fruit sets well in heat and is a reliable “black” tomato, producing even under adverse conditions from summer to fall. Make sure to stake or cage, as the plants can reach 6′ or more!
Cherokee Purple: Cherokee Purple’ is said to have been given to a Tennessee family by the Cherokees over 100 years ago. This dark maroon tomato has just the right balance of sweetness and even a hint of smoke, making it a winner in taste competitions. From summer into fall, you will harvest lots of 10–12 oz. tomatoes from this well-regarded heirloom variety. Make sure to stake or cage, as the plants can reach 6′ or more!
Chocolate Cherry: Chocolate Cherry tomatoes—Yum! These 1″ purplish-red, delicious tomatoes are great for snacking on and add a bit of sweetness to salads and pasta. The prolific vines bear seemingly endless trusses with 6–8 ounce fruits that will bring you back for harvest after harvest. Fruit is crack-resistant! Make sure to stake or cage.
Watermelon
Sugar Baby: The taste of summer? Watermelon! As the name suggests, ‘Sugar Baby’ is sweet, sweet, sweet! It is also small enough to easily fit in the refrigerator. This plant produces a bountiful crop of 8–10 pound deep dark emerald green orbs that have juicy red flesh.
Zucchini
Black Beauty: Black Beauty is an early maturing zucchini-type squash that features delicious deep black to green fruits with pale flesh. A very easy-to-grow bush variety that is highly productive all summer long. Enjoy grilled, sauteed, fresh, in soups, or zucchini bread!
