August Gardening To-Do List for Zones 3-8

August gardening to do list

What to do on your Property in August – Cold Temperate Climates

It’s the peak of the summer heat and this is the time of year that our gardens are feeling it the most.  However, there are still plenty of things to be doing on your property this month.  This list is tailored for cold temperate climate growing zones, but if you are looking for warm temperate or sub-tropical growing zone lists CLICK HERE.

In the Garden

  • Things to plant by seed:  beets, carrots, radishes, and turnips.
  • Fall greens:  In order to stagger your harvest times later in the fall, consider planting smaller amounts of fall greens (salad mixes, kale, etc.) every other week.  The same can be done with beets and radishes.
  • Brassicas:   Plant broccoli, cabbage, and cauliflower by seed or transplants.  Keep them well-watered (1″ per week) as they get established and mulch with straw around the base to cover the soil and prevent water evaporation.
  • Harvest:  tomatoes, eggplants, peppers, and other night shades.  Prop up plants as needed to provide support.  
  • Mulch:  Keep bare soil covered completely to prevent water evaporation and protect microorganisms.  Add a little more compost and wood chips around fruit trees and berry bushes.  Add another layer of straw around garden veggies.  
  • Compost application:  Add fresh organic compost to strawberry patch (thin them while you apply compost).  You can also add compost to bramble canes (blackberries and raspberries) to improve next years harvest.

It’s time to start making tinctures and drying herbs.

In the Greenhouse

  • We are finished with the “greenhouse” season, but if you have a shade cloth, you can actually open up all the windows now and put the shade cloth over the top. This will allow you to start micro-greens and other later season veggie starts. If using a shade cloth, use the opened greenhouse for your indoor tropical plants to give them a season outdoors. Just be sure to pay attention to your watering!
  • Clean and sterilize the plastic pots used this winter / spring
  • Set mouse traps to control critters
  • Hang fly trap to control aphids, flies, and other pests

In the Food Forest

  • Harvest berries that are ripe: goji, elderberry, blackberry, raspberry, etc.
  • Mulch: Apply mulch / wood-chips around the base of fruit trees. Keep the wood chips away from the base of the tree, because if they touch the trunk it can cause rot or bacterial issues. Wood chips will encourage mycorrhizal activity and strengthen the root system.
  • Herbs around fruit trees:  Start harvesting herbs to dry and make tinctures, harvest fruit as they are ripe and remove those that fall to the ground. Fallen fruit calls in the pests… So feed to chickens or add to the compost pile.
  • Harvest elderberries:  If you are making elderberry tinctures, teas, or wine – now is your time to harvest. Whatever you do not harvest, the birds will take care of for you. It is also a great time to harvest elderberry canes for cuttings and propagation.
  • Watch for fungal issues on leaves and apply organic neem spray as needed.
  • Plant late summer ground covers in any “bare spots” around the forest. Consider things like daikon radish or crimson clover. Water the first 10-12 days until established.
  • Wait to plant new fruit trees and berry bushes until next month, when the heat dials down a few notches.

Reminder: Elderberry must be cooked before eating.

In the Shed

  • After heavy spring and summer use, give power tools a quick check (oil, air filters, and clean off exteriors).
  • Check mouse traps and keep animal feed in sealed containers.
  • Give cutting tools a good cleaning (using rubbing alcohol) and oil afterwards to prevent rust.

In the Chicken Coop

  • Chickens:  Some of the early spring chickens will start laying soon. Once the first egg has appeared, switch chickens over to a layer feed and/or provide supplemental calcium.
  • Harvest comfrey and feed to chickens, horses, goats, and cattle.
  • Quail:  Mix apple cider vinegar and honey with their water once a week. Pick fresh flowers and grass seed heads to put inside their coop and nesting area. This is a great time to provide supplemental protein using meal worms and small crickets.
  • Deworm: Use 1 tablespoon of Basic H in a 5 gallon waterer (1tsp per gal) for chickens (NOTE: Use the original formula of Basic H, which comes in a 5 gallon bucket OR 30 gallon drum). Add 1.5 cups to a 100gal waterer basin for cattle and horses. Available in bulk (much cheeper for farm use) This should be their only water source for two days.
  • Coop clean out: On a sunny day with a breeze, clean out the coop in the morning. Use Basic H organic cleaner and spray everything out. Leave the coop open all day to dry it out with good airflow. Clean out all waterers and feeders using a bleach solution.
  • Add wood ash to the dustbath to help prevent and treat lice and mites.

Around the House

  • Keep South and West facing shades closed during the day time in order to block out the hot sun.
  • Open up the windows on cooler nights to help air out the house and let in fresh air.
  • Replace your HVAC filters
  • Check batteries in smoke alarms and carbon monoxide detectors
  • Wash windows (inside and out). Use a product like “Invisible Glass” to avoid streaks.
  • Clean outdoor windows and doors (I use Basic H for this)
  • Apply UV protectant to your recreational vehicles (boats, car interiors, RV’s, decals, etc.
  • Spray tire shine and protectant on vehicle and trailer tires to prevent sun damage
  • Give houseplants a good fertilization and shower to clean off leaves
Add kid-friendly elements, hobbit holes, and fairies to the perennial flower bed.

In the Perennial Flower Beds

  • Dead-heading: Cut back spent flowers in order to get a second bloom. Spent flower heads can be fed to chickens or composted.
  • Plant seeds of larkspur, holly hocks, and poppies for next year
  • Add extra wood chips to areas that are in full sun in order to protect soil health and microbial activity
  • Bring cut flowers indoors and share with neighbors, especially those who are shut-ins or elderly
  • Find / create garden activities that involve kids.
