Fall 2020 Garden Calendar

2019 late summer / early fall garden. (Embarrassed to show you the state of our 2020 garden.)

  • 2020 has been a challenging year for Colorado gardeners. We faced many obstacles, including drought (our irrigation ditch ran dry mid-July), record high temperatures, fires and smoke, and an early freeze.
  • Direct-seed fall crops, like greens and radishes. Aerate your soil by hand-tilling and add compost. We currently have: Sheep, Peat, and Compost; EKO Compost; and EKO Clay Buster (compost with added pumice).
  • Tomatoes continue to ripen quickly. Pick off any new flowers as they will not have time to mature. The plants will then focus on ripening existing fruit. Prior to a hard freeze, remove any green tomatoes and let them ripen inside, making sure they do not touch each other. Another alternative is to pull the entire plant and hang it upside down in a heated space.
  • Harvest apples, grapes, and berries.
  • Hand pull as many weeds as possible. Do not add them to your compost pile.
  • Use Horticultural vinegar on weeds during the hottest part of the day and pull them the next day.
  • Remove dead annuals and cut back diseased or injured parts of perennials. We do a hard prune of perennials in the Spring.
  • Apply lawn fertilizer in late September to mid October. Use a natural and organic lawn fertilizer, such as Pro-Rich Turf Food.
  • Add compost, nutrients, and amendments to your entire garden. This will give you a head start in the Spring.
  • Mulch in perennials to insulate them, using a combination of compost and mulch.
  • Before a hard frost, schedule a professional tree pruning so that early snows won’t damage valuable trees.

The secret to using farm fresh eggs is how to boil and peel them

Add eggs to pot
Cover with cold water
Bring to boil
Remove from heat and let sit 12-15 minutes with lid on
Immerse eggs in ice bath
Crack shell into very small pieces and roll it gently between your hands
Peel under running water
Make sure to remove shell and membrane together to keep egg intact

Garden Maintenance and Pest Control

August Garden Calendar

– Harvest crops often so they continue to produce. Use clean small shears to harvest instead of pulling on plants or stems. Beans, tomatoes, cucumbers, summer squash and corn are ready to harvest.
– Peppers can be harvested as small as 3 to 4 inches in length. Red bell peppers need more time on the vine, but it’s OK to harvest them while green.
– Bigger eggplants aren’t better, so harvest when they are large enough to use, but before their skin loses its gloss.
– Are your tomatoes setting fruit? Consistent temperatures over 90F inhibits the plant from setting fruit. Tomato and Pepper Set Spray makes blossoms set fruit despite hot weather. Nearly every blossom will produce larger, meatier, tomatoes, ripening up to 3 weeks earlier. May be used on Tomatoes, Beans, Cucumbers, Eggplants, Melons, Okra, Peppers, Strawberries and Grapes. It promotes flowering, increases blossom set, reduces end root, and increases fruit yield.

– Clean up flower containers by pruning for shape or getting rid of spent flowers and dead patches.
– Deadhead spent blooms, pull weeds and plan.
– Purchase fall bulbs, including garlic, and save some money to buy bulbs from your local garden center later in fall.
– Mid-August is the recommended last feeding time for roses. Fertilizing later in fall may result in more lush growth too close to the first frost. We carry Natural Guard Rose & Flower fertilizer. It is OMRI and 3-4-3.

– Protect your plants from being eaten by deer, bunnies, or rodents. Bobbex is a fantastic product that uses natural and safe ingredients to repel deer and other herbivores. It also repels herbivorous insects.

– Powdery mildew may appear on susceptible plants like bee balm, veronica, lilac, roses, squash and pumpkins. Neem oil and sulfur based fungicides are effective controls. We have both in stock. Safer 3 in 1 is a great product. It controls both insects and fungus.

– Sprinkle Diatomaceous Earth (DE) around plants to deter pests. As an insecticide it is not poisonous, rather slugs and snails do not like to crawl over DE because the silica skeletons are very sharp-like tiny pieces of broken glass. The result is cuts to their soft bodies, loss of fluid and eventual dehydration. This process works on soft bodied insects, including caterpillars and aphids, and on those with hard shells too such as beetles, fleas, cockroaches, and even bed bugs. Sprinkle bands of it around the plants or you can dust the leaves of a plant, for example, potatoes that are infested with potato beetle larvae. We carry Natural Guard OMRI Diatomaceous Earth.
