One of the easiest crops to grow- corn is a grass type plant.
It likes it sunny with supplemental nitrogen.
“Knee high by the 4th of July” is the adage that determines if you’ll be harvesting or not!
Seeds can be soaked overnight before planting to help break the seed coat. Sow just below the soil line.
Overall, the crop excels with a fertilizer or soil nutrient high in Nitrogen.
One of the first crops we get to seed in the ground early spring!
Pre-soaking the seeds overnight (or several nights) helps the seed take up water and break the seed coat.
From years of experience we find this ensures 70-80% success in germination. Some use an inoculant to try to stimulate better germination, but its success varies.
Take into consideration that they don’t like the heat, so choose a site where the temperature won’t spike early in the summer.
Peas like rich soil with consistent moisture. Be careful early in the season to not overwater the young plants!
When the heat hits, they slow in production. Sowing again in mid-July can produce a healthy fall crop.
Garlic is a bulb that usually is planted late summer/early fall and harvested the following summer or fall depending on the variety.
Ideally when they are planted they will have time to root in sufficiently to endure the winter and late enough in the season to avoid tall green shoots that could freeze. They can be planted early spring and harvested late fall- but may not reach their full potential.
Garlic is grown all around the world!
Hardneck varieties are hardier and best for this region.
Soil should be rich in organic matter but should drain easily (especially if there’s consistent moisture during the winter).
During the summer a light mulch layer of leaves or clean grass clippings on the soil can prevent the soil from moisture extremes.
The bulb or cloves need to be broken into individual segments. The tip of the clove goes just slightly under the soil level, green sprout (or pointed side) up.
In a world laden with synthetic and even organic pesticides, wouldn’t it be nice to return to a harmony with the way things are supposed to be, where the good bugs eat the bad bugs? If we provide the right plants, they will come…
Alyssum: flowers attract hoverflies whose larva devour aphids; draws bees to pollinate early blooming fruit trees
Borage: deters tomato hornworms and cabbage worms; one of the best bee and wasp attracting plants.
Carrots: blooms attract hoverflies and predatory wasps
Calendula: attracts bees and hoverflies
Catnip/Catmint: deters flea beetles, aphids, Japanese beetles, squash bugs, ants and weevils.
Chamomile, German: host to hoverflies and wasps.
Centaurea: attracts bees, lacewings, hoverflies and parasitic wasps.
Chives: attract hoverflies, bees and parasitic mini-wasps; keep aphids away from tomatoes,
Chervil: keeps aphids off lettuce
Cilantro: repels harmful insects such as aphids, spider mites and potato beetle. A tea from this can be used as a spray for spider mites
Cosmos: attracts lacewings, hoverflies and parasitic wasps
Dill: flower umbel attracts ladybugs, lacewings, hoverflies and parasitic mini-wasps but also the tomato horn worm so it would be wise to plant it somewhere away from your tomato plants.
Fennel: foliage and flowers attract hoverflies, ladybugs, tachninid flies, beneficial parasitoid wasps. It can retard the growth of some nearby plants.
Garlic: systemic in action as it is taken up by the plants through their pores and when garlic tea is used as a soil drench it is also taken up by the plant roots. It has value in offending codling moths, Japanese beetles, root maggots, snails, and carrot root fly
Golden Rod: one of the best; attracts assassin bugs, big-eyed bugs, ladybugs, lacewings, hoverflies, praying mantis and parasitic wasps.
Lavender: repels fleas and moths. Prolific flowering lavender nourishes many nectar feeding and beneficial insects. Lavenders can protect nearby plants from insects such as whitefly, and lavender planted under and near fruit trees can deter codling moth.
Marigold: has roots that exude a substance which spreads in their immediate vicinity killing harmful nematodes.
Mint: the menthol content in mints that acts as an insect repellant and tiny flowers attract Braconid and Icheumonid wasps, and Tachnid and Syrid flies; bees and other good guys love it; deters white cabbage moths, ants, rodents, flea beetles, fleas, aphids. Earthworms are quite attracted to mint plantings, and it may deter ground squirrels and mice from tunneling in the area.
Morning Glory: attracts syrphid flies and ladybugs
Nasturtium: deter aphids, squash bugs, and striped pumpkin beetles.
Oregano: plant near broccoli, cabbage and cauliflower to repel cabbage butterfly and near cucumbers to repel cucumber beetle.
Parsley: flowers attract parasitic wasps and hoverflies.
Thyme: deters cabbage worms.
Yarrow: attracts predatory wasps and ladybugs; good accelerant to the compost pile.

Low, mounding plants with scalloped leaves in a multitude of colors. (perennials in some parts of the city) Use these for unique foliage in your annual combos. In addition to the pretty foliage all season, tall wispy flowers are held in swaying wands above the leaves for a month. Flowers are attractive to hummingbirds.
Exposure: Sun, Part Sun, Morning Sun, Shade
Bloom Time: Summer
(Asclepias) Flowers from this plant are the favorite food of the monarch butterfly. They are a bright orange and are also attractive to other butterflies as well as hummingbirds. Treat yourself to a bouquet from your backyard as they also make a great cutflower. Adapts well to poor soil as long as it is well drained. Drought tolerant. Takes a few years to really establish well, but long lived after that. Native wildflower that WILL self sow if allowed. Let it naturalize OR easily control growth by removing seed pods early on.
Exposure: Sun
Bloom Time: Summer
Tuberosa: 24″H x 24″W. Zone 4.
Ever see a breath taking combination and think- I want my stuff to look like that? Easy! When in doubt- copy what others do! It’s not rocket science- just a little “know how”. A quip to fall back on is “thrillers, fillers and spillers”. In a nut shell that means: “POW” with a few really pretty bloomers, a few falling over the side and a supporting cast of complimentary foliage.
For example, in a hanging basket we use:
Thriller= a Geranium or Osteospermum for Sun
or Begonia/New Guinea Impatiens for shade
Fillers= Coleus, Grasses or Ferns for shade
Spillers= Calibrachoa, Petunias, Sweet Potato Vine or Vinca Vine
Big Pots: Go Big! Calla Lily, Big Easy Geranium, Marguerite Daisies, upright Salvias or Pennisetum grasses.
Shade Pots: Use different types of foliage…there’s no dead heading and they are calmer to look at! Or embrace the Begonias, Fuschia, Impatiens and Torenia. (There’s much more to choose from see selections in our Annuals section)
More tips:
We create hundreds of hanging baskets and containers each season. Come visit us in early May for the best selection. Want us to fill your existing container or pot up a specific combo? No problem… just tell us your sun exposure and desired color scheme and we’ll do the rest.
Our region has a wide diversity of growing climates and micro niches. Most long-timers go with short season crops, foregoing the big tomatoes and watermelons finding those at the Farmer’s Markets!
At first, experience success with the short season crops before moving onto the bigger challenges.
On the seed packet it will give “Days to Harvest”. In Colorado Springs, estimate June 1 as day one. Our first killing frost is approximately Oct 1. So let’s say 120 good growing days without hail or rogue frosts.
Crop time needs to fit in there or add protection at the beginning or end of the season. If it’s short harvest times, plant succession rows to keep the harvest coming!
Seasoned gardeners know that a bountiful garden isn’t an accident- it takes planning. It can be as simple as generating a row of lettuce to pulling off Beefsteak tomatoes, a 300# pumpkin or the 3rd rotation of broccoli- it just all depends on what your ambitions are! Don’t be scared…start simple and you’ll be successful!
Plants are categorized by many definitions but for now, let’s first address “cold crops” including the Brassica group (broccoli, cabbage, cauliflower, etc.) lettuce, spinach, chard and other plants that are not adversely affected by low temps and snow. Direct sown crops could include carrots, peas and radishes. We gauge start times looking at our average last frost date of May 15. Many of the cold crops we grow are ready for planting around April 15 and later. Sowing seed for cold crops can be done around the same time and they will sprout when the temperatures are warm enough. Potatoes fall into this category too because their leafy sprouts will clear the soil around the last frost date.
If cucumbers, peppers, squash, tomatoes are the sort of plants you want to grow- wait until around mid-May, they don’t like freezing temps. Some folks wait until Memorial Day just to make sure. Some just can’t wait, planting tomatoes in April, putting protection around their investments until June. Yep, those gardeners often have the advantage, because although you can’t see it, the plants are developing strong roots. Once the warm weather hits, they are ready to roll!
Colorado has rogue weather- keep an eye to the sky and protect the tender plants from freezing. Cover with cloth because plastic can conduct the cold if it touches the leaves. Or make sure the plastic is suspended over the plants. Keep in mind snow cover will keep plants at 32*; ambient air temps can go lower! Uncover plants when the temperatures will hold above freezing.
How does that neighbor get the prettiest blooming yard? If ever you catch gardeners in their yard, ask! Most gardeners would love to talk (on and on) about their yards. Once they start, the information turns to Latin and it’s all over! You’ve just encountered a plant nerd. It feels safest to retreat to the store and buy one or two packs of petunias. Then, as the summer goes on you find it’s just not the same impact! Chalk it up to another year of gardening over!
Too much information can make flower gardening daunting.
Let’s see if we can break it down so you can find your level of interest and enjoy it! The term “wildflower” can be deceiving. Blooming natives may come to mind. By some standards it defines annuals that bloom all summer and generate plants by seed the following years; examples: alyssum or California poppies. Blends of wildflower seed may contain “fillers” including clover. Unless you know the difference between flowers and weeds, this endeavor can become a nightmare! Individual seed packets solve that problem. Read the packets for ideal growing conditions. This route can be disappointing: initially you water more; the water brings weed and grass seeds as well, leading to more weeding; not all the varieties do well.
Buying plants gets costly but there’s immediate gratification. Here’s a guide to some types.
Annuals: are least expensive and generally will bloom all summer but will not come back the following year.
Bi-ennials: bloom all summer and will perform for two years, example: pansy, viola and dianthus. Perennials: should come back from the root each year but may bloom only a portion of the summer. Perennials can be native, which is indigenous, but may not be as showy, example: pussytoes and delphinium. Other varieties are hardy to the region, introduced from elsewhere or a hybrid that can survive here. Some perennials are less tasty to deer (daylilies) and some thrive in the shade (hosta). Many can survive with less water than annuals once they have been established. Providing mulch and good soil amending can also reduce watering.
Colorado based publications narrow the scope into our region- bringing the selections into a more manageable data base. Colorado Nurseryman and Greenhouse Association has booklets for sale at reputable Garden centers, CSU offers publications on line that are very specific. Start by finding the website http://www.ext.colostate.edu. There you’ll find information on:
Wildflowers- publication #7233
Perennials- publication # 7405
Natives- publication #7242
Mountain flowers- publication #7406
Xeriscape- publication #7231
For yards with deer scroll down to Wildlife for publication #6520
Some rules of thumb:
Full Sun = 6-8 hours of direct sun
Partial Shade = filtered light all day or approximately three to five hours direct sun
Shade = less than three hours sun.
Zone: We are USDA Zone 3 or 4 depending on your location. (Click here for more info from the USDA) Altitude does make a difference! One season doesn’t make a garden. It’s a lot of effort and some money. Easiest start is grab a cup of tea or coffee, peruse the publications and highlight what suits you. That makes you a smarter shopper and better gardener!
