August Gardening To Do List by Planting Zone
Use our free tool if you don't know what your planting zone (or Hardiness Zone) is yet.
1. Save the Seeds
If you have specific plants which did well this year, save their seeds. Instead of pulling the plants up when they’ve finished yielding, allow them to go to seed.
However, if it’s a plant which produces fruit (such as peppers or tomatoes), then remove the seeds from the fruit produced and dry them for later use.
Some plants in your garden should still be producing this month. Squash is one which should be providing you with a decent yield at this time.
Wait until the squash are approximately four to eight inches in length before you harvest. This will encourage more production.
3. Protect Your Squash
Since squash is a quick growing plant which can produce quite the harvest, it’s important to know how to protect them.
Spray the squash plants down in the morning. It should help to alleviate some of the threat brought on by aphids.
4. The Half Way Point
Approximately two weeks into August, begin removing flowers from tomato plants. Doing this will encourage the plants to focus more on ripening the tomatoes already produced. Instead of putting energy into forming more fruit.
5. Harden Off Perennials
August is a time when you should begin preparing perennials for the cold winter months. You do this by lowering the amount of water given to them.
6. Prep for Frost
As the seasons change, it’s important to begin preparing your plants for frost. Sometimes frost comes earlier than expected.
Go ahead and have sheets, plastic, towels or even cold frames ready to cover plants when the frost comes on without much warning.
7. Bring in Houseplants
During the summer, some people put their houseplants outdoors to give them breathing room and direct sunlight.
If you’ve done this too, August is a good time to begin bringing the plants indoors. You need to get them acclimated to their winter setting before the frost.
8. Overwinter Plants
August is also the right time to bring plants you started outdoors, indoors. Some plants don’t do well over the winter if left outside.
In those cases, it’s important to bring the plants indoors where they can be protected from the elements. They can be moved back outdoors after winter.
1. Plant a Quickie
If you live in zone 4, now is the time to plant fast-growing plants. You still have time to have more fresh vegetables in your garden.
However, be sure to choose crops (such as lettuce) which will produce abundantly and quickly before the weather gets too cold.
2. Spring Bulbs
If you plan on having pretty blooms in the spring, August is the month to get started. Choose the bulbs you desire to bloom in spring.
Once decided, shop for the bulbs this month. They’ll need to be planted next month which is why it’s important to have them on hand.
3. Thin Out Strawberries
Strawberries will reproduce quickly. Sometimes the beds of berries can become overcrowded. Now is the time to thin out the strawberries.
You can either remove certain plants and toss them to the compost, or you can transplant the overcrowded strawberries in another bed.
4. Save Certain Seeds
August is the month to begin retaining tomato and pepper seeds for next year’s planting. By saving seeds, you not only get the desired genetics you want, but you also save money.
5. Pull Out the Cold Frame
6. Lay Dead Crops to Rest
As the seasons prepare to change, the summer garden will inevitably end. The plants will begin to die off and stop yielding any produce.
Now is the time to pull up the dead crops and plant a cover crop. The cover crop will help protect your soil from the harsh elements of winter.
1. Time to Cut’em Back
Have your berries stopped producing? Are the canes shooting out every which way? It’s time to end the madness.
Once the berry plants stop producing, prune the canes back. Pruning will help them to look better and stay healthy.
2. Weed and Mulch
If you have strawberry beds, it is time to take care of them. Be sure to remove any weeds which may have moved into the beds.
Once all the weeds have been removed, cover the strawberry plants with a thick layer of mulch. Mulch will insulate the plants and protect the soil.
3. Put the Volunteers to Work
It’s common to have strawberry plants start voluntarily in the beds. Instead of allowing over-crowding to take place, transplant the volunteers to a new bed.
Then you will have adequate spacing in each bed, and it’ll also give you a larger strawberry harvest in the years to come.
4. Get Busy Planting
What a delicious fall harvest you’ll have by putting in the work now. You’ll be glad you did when you’re craving something fresh.
1. Water Strategically
It’s common for August to be a dry month in some places. If this is the case in your area, be sure to pay close attention to your plants.
When you don’t get enough rain, be sure to supplement by watering your plants deeply once per week.
2. Time for Lettuce and Spinach
You’ll have a harvest in no time flat and still have ample time to enjoy the freshness your garden provides.
3. Pull Out the Pansies
If you want gorgeous blooms in the springs from pansies, now is the time to get started. Start pansy seeds indoors this month.
Once the seeds have grown, harden them off, and plant them outdoors. This way they’ll bloom in the spring.
4. Sow Spring Blooms
August is also the perfect time to sow other flower seeds. If you enjoy flowers such as poppies, directly sow them into the desired area this month.
They won’t do anything immediately, but when spring rolls around again, you’ll have gorgeous flowers everywhere.
5. Dry Herbs
Herbs are best harvested when they’re in full swing. For that reason, harvesting herbs should be on your radar this month.
Once the herbs have been harvested, dry them for later use. This way you can enjoy flavorful herbs for months to come.
6. Start Shopping
August is the month to begin shopping for bulbs which produce spring blooms. You also need to buy garlic bulbs.
You can plant them both during the fall and have a beautiful array of spring flowers. Plus, you’ll have a nice harvest of garlic too.
1. Water Strategically
August can be a dry month. Make sure you supplement water as needed. Be sure to water your plants one time per week.
But also, be sure to water the plants deeply during this watering. This will make up for any natural water shortage.
2. Get Busy Planting
3. Towards the End of the Month
The end of the month is a busy time to begin transplanting vegetables. If you started vegetables indoors such as Brussel sprouts, broccoli, and cauliflower, now is the time to plant them in your garden.
1. Prune the Berries
When your berry plants finish up their harvest, it’s the perfect time to prune them back. This will help keep the plants healthy and hopefully encourage a greater crop the next growing season.
2. Dry Herbs
It’s best to harvest herbs when they’re in full swing. August is a month when herbs begin to thrive in this zone.
When your herbs begin producing heavily, harvest them. Once they’re harvested, dry the herbs. Then you can enjoy your herbs all year long.
3. Protect Your Soil
August is a time when you need to consider protecting your soil over the winter months. One way to do this is by planting cover crops.
Whether you garden in an ample space or a smaller garden bed, consider planting a cover crop to protect the soil from the harsh elements of winter.
4. Apply Compost
Are you planning a fall garden? August is the month to apply compost to the fall gardening spot. Then there will be enough time for the compost to break down before being needed by your fall vegetables.
5. Transplant Nightshades
Do you like to have a later harvest of tomato and pepper plants? Well, this is the month to transplant both types of plants into their designated grow spot.
Once they’re transplanted, they should be able to produce until frost takes place. If you can protect the crops during the frost, you may even be able to enjoy fresh tomatoes and peppers later than expected.
6. Get Busy Sowing
Some plants do better when directly sown into the ground. You may be under the impression August is too late to directly sow anything.
1. Prune Your Plants
If your tomato and pepper plants are in full swing, you’d probably like to keep them this way. This is the month to prune both types of plants.
Pruning will encourage the plants to grow and produce more. Which is what you want if you enjoy fresh veggies.
2. Pull Out the Shades
August can produce high temperatures and harsh sunlight. Some plants need shade from the intensity of the sun.
If you’re growing tomatoes, peppers, eggplant, melons, or lettuce, be sure to plant them where they can find reprieve from the scorching sun.
3. Boost the Pumpkins
Are you trying to grow giant pumpkins? Pay close attention to them this month. When you see other fruits begin to develop or female blossoms, be sure to remove them.
By removing either the fruits or female blossoms, it’s encouraging the plant to put its energy into the fruit already growing instead of producing more.
5. Plant Some Fall Color
Marigolds are useful flowers, but they also produce a gorgeous golden color. If you’d like to have pretty golden flowers during the fall, now is the time to plant marigolds.
6. Plant Spring Blooms
Are you looking for a flower to plant now to have gorgeous blooms in the spring? Well, consider planting forget-me-nots now for the beauty they’ll provide you later.
7. Plant Garlic
August is the month to plant garlic. If you’d like to have an excellent spring harvest of a crop which requires little care, garlic is what you’ve been looking for.
8. Deadhead Plants
If you grow plenty of flowers during the summer season, now is the time to begin deadheading them to prolong their lifespan.
Also, if you grow roses, August is the month to deadhead them as well. Deadheading is essential to turn back the clock on plants.
9. Fertilize Citrus
If you grow citrus trees, you’ve most likely been busy harvesting from them around this time of year. Be sure to fertilize citrus plants after the harvest to give them the nutrients they need to remain healthy and viable.
1. Work on Indoor Plants
If you have indoor plants, now is the time to remove them from their old soil and repot them into fresh soil with fresh nutrients. Repotting will ensure your plants stay healthy.
2. Get Busy Planning
August is the month to get busy planning your fall and winter vegetable gardens. It’s important to note when to start seeds and when to transplant seedlings.
3. Start Plants in Pots
If you’d like to grow nightshade plants or melons, start them in pots this month. They’ll need adequate shade from the sun during the hottest part of the day.
4. Offer Shade
Your compost pile will need shade this month. Be sure to place it in a location where it can have natural shade or add sheets, plastic, or palm leaves over the pile.
However, be sure to cover it loosely. The pile will still need room for air to circulate and maintain adequate airflow.
5. Apply Compost
Any vegetable or fruit in your garden which is producing this month needs a helping of compost. Be sure to add an adequate amount around the base of each plant to give them a natural boost.
6. Kill Weeds and Seeds
If you have empty garden beds, fight the weeds and keep them from going to seed. You can do this by adding a good amount of water to the soil. Doing this will encourage the weeds to sprout.
However, you cover the soil with clear plastic and leave it alone for approximately two months. By the end of the two months, the weeds should have sprouted and died under the heat.
