Planning My Fall Garden

Planning My Fall Garden


After years of planting a vegetable garden, I finally learned that one can plant continuously throughout the season.   By mid-July, garlic, peas, and spring crops have been harvested leaving room in my garden.    Planting more seeds will keep the weeds at bay and provide more crops for an autumn harvest.   Cooler autumn days are a mere month away,  so its time to gather seeds and make a plan to get those crops in while the days are longer and the temps are warm.   This method of following a harvested crop with another is known as succession and/or seasonal planting.

The following is a list of some of the crops I’ve successfully planted in late July/early August:

  • Arugula, Beans, Beets, Broccoli, Cabbage, Carrots, Kale, Kohlrabi, Lettuce, Mesclun, Pak Choy, Spinach, Swiss Chard, Peas

Crops planted in late July are taking off by late August — beans, cabbage, beets, kale.


There are more options including curly parsley, claytonia, turnips, mizuna, radish, endive, leeks and mache.   For a successful late fall harvest, you need to time your cold-season crops properly.   They should be planted when the weather is still warm — in late summer or early autumn — and while there is still more than 10 hours of sunlight per day.     Cold-season crops should be almost mature by the time the cold weather finally arrives in late autumn.   Protecting the vegetables with a season extender like a cold frame or hoop tunnel will enable them to hold on through the winter.





Getting the cold frame ready for late summer planting of cold crops.

Here are some examples of fall crops planted from locally purchased seeds:

Scarlet Nantes Carrot

  • Days to germination:  12-18 days
  • Days to maturity:  65-75
  • Plant dates:   August 1-31
  • Harvest date:  October 10-November 15

Early Vienna White Kohlrabi

  • Days to germination:  6-12 days
  • Days to maturity:  58 days
  • Plant dates:  August 10-September 10
  • Harvest date:  October 15-November 15

Chinese Cabbage – Pak Choi

  • Days to germination:  5-7 days
  • Days to maturity:  50 days
  • Plant dates:  August 10-September 10
  • Harvest dates:  October 5-November 5

Red Acre Cabbage

  • Days to germination:  7-12 days
  • Days to maturity:  65 days
  • Plant dates:  August 1-5
  • Harvest dates:   October 6-15

Ruby Queen Beets

  • Days to germination:  10-14 days
  • Days to maturity:  55 days
  • Plant dates:   August 1-15
  • Harvest dates:  October 5-15

When its time to start,  I gather my supplies, clean up the planting area and add compost if needed.   I set aside a day in late July/early August to plant seeds.  If I have time, I’ll do a second planting a week or two later.   I make sure to map out my crops on paper and mark the rows well so I can see what’s coming up.


My friend Jen helped me plant carrots, beets, lettuce, kohlrabi, cabbage and more.. August 4, 2017.

This last round of crops is awesome but can be a challenge to process with the avalanche of tomatoes, peppers and other warm season crops that pile up just after the first frost — late September to late October in Denver.   Make sure to set aside time for cooking and preserving in September and October.  I often invite friends over to preserve together to make it more fun.  The investment in time will be worth it.   The planting is easy and  you grow more than you can eat or preserve, share the surplus with friends or donate to the local food bank.

I challenge you to plant a fall garden and you’ll be happy with the results!


The broccoli in the raised bed survived the frost and we harvested into November.





Seasonal, Succession and Companion Planting – Workshop at Ute Trails Garden, 5/7/17

Seasonal, Succession and Companion Planting – Workshop at Ute Trails Garden, 5/7/17

13177550_1116499921748060_2580476015789243526_nSince becoming a master gardener in 2013, I frequently give workshops at local community gardens.   Today, I had the opportunity to give a workshop at Ute Trail Garden in Lakewood where several of my friends garden.   I am sharing the outline of my program for those who could not attend or would also like to learn about seasonal, companion and succession gardening.

The following are methods used by successful gardeners to maximize their harvest, minimize pests and promote healthy soil.

Companion Planting

  • Some plants grow well together, others do not
  • Some plants, especially herbs, act as repellents, confusing insects with their strong odors that mask the scent of the intended host plants.
  • Dill and basil planted among tomatoes protect the tomatoes from hornworms, and sage scattered about the cabbage patch reduces injury from cabbage moths.
  • Marigolds are as good as gold when grown with just about any garden plant, repelling beetles, nematodes, and even animal pests.
  • Carrots, dill, parsley, and parsnip attract garden heroes — praying mantises, ladybugs, and spiders — that dine on insect pests.
  • Much of companion planting is common sense: Lettuce, radishes, and other quick-growing plants sown between hills of melons or winter squash will mature and be harvested long before these vines need more leg room.
  • Leafy greens like spinach and Swiss chard grown in the shadow of corn
  • Sunflowers appreciate the dapple shade that corn casts and, since their roots occupy different levels in the soil, don’t compete for water and nutrients.

Seasonal Planting

  • Cold season vs. warm season crops
  • Last frost date – keep track – generally mid-to –late May in Colorado
  • Cold season crops can be planted before the last frost and some can overwinter under mulch examples: lettuce, kale, carrots, spinach, radishes, onions, sweet peas
  • Warm season crops are planted after the last frost and some need the soil to be warmer examples include pumpkins, squashes, many flowers, beans, basil, corn, sunflowers, tomatoes, peppers, melons

Succession Planting

  • Benefits of succession plantings: maximize space,  extend  harvest window, maintain a continuous supply
  • Make the most efficient use of space and timing to increase productivity
  • Two or more crops in sequence.After one crop is harvested, plant another in the same space.      Plant lettuce every 3 weeks; two crops of carrots
  • Interval succession planting.  Make repeated plantings of the same crop, planting the same variety at timed intervals.     Succession Planting Interval Charts.
  • Two or more crops concurrently.  Plant several different varieties, typically with different maturity dates    Sometimes referred to as “intercropping” and “companion planting.”
  • Same crop, different maturity dates. Plant several varieties, with different maturity dates — early, mid season, and late — at the same time. As they mature over the season, you harvest them one after the other.

My friend Laura Stevens is one of the leaders at Ute Trail and gave me a tour of the community garden. Here she is in front of her plot. I love how she used thyme for her paths!
