August is the time to clean up beds and borders after crazy development in the middle of summer. Once flourishing and delicious leaves give way to the aging of yellow leaves. The tallest plants of weeds begin to bend and fall while the clusters that form the barn start growing long. All this may give rise to a random look at the garden in August. Although the hottest of the season is behind us, August can still offer the best of sunny and more reliably dry weather. 

Gardening tips for August, flower, vegetable, fruit, & herbs gardening in August, greenhouse care, trees and shrubs care, and general plant care in August

Flower gardening in August 

  • It is the perfect month to divide Iris. Lift the entire clump with a spading fork and throw away the oldest, open parts in the middle. Cut the new 6 inches wings outside the clump and replant them to an area made from fertilizer, peat moss, or rotten manure and enrich them with some 5-10-10 manure. Cut the leaves back to 6 inches on the new wings and plant just below the surface of the earth. Water well and mulch in late fall to protect plants from extreme cold.
  • Removing many annual and perennial spent flowers will keep the plants more attractive and encourage re-opening. As the weather progresses, the birds begin to release flower stems to provide seeds and catch the snow.
  • Collect seeds ripening from plants like Aquilegias, sweet peas, and love-in-a-mist, choose a dry day. 
  • Deadhead to encourage the steady display of Dahlias and other perennial flowers. 
  • Keep the Camellias and Rhododendron well in the water in the late summer while their flower buds are made. 
  • Trim the lavender once the flower is in, to maintain a compact, bushy shape, but avoid cutting into old wood. 
  • Trim the Rumbling Rose, remove up to a third of the stem that has flowered, and tie the rest to support. 
  • Keep the pots and hanging baskets flowering regularly through water and dead headings, and add the tomato dose to a fortnight.
  • Take woody herb cuttings including Lavender, and Hyssop, choosing unflowered shoot. 
  • Sow hardy annuals in sunny spots to provide color in early summer next year. 
  • If you’re going on holiday, set up an automatic water system for pots and hanging baskets. 
  • Take softwood cuttings from the Penstemons, choosing a healthy, vigorous, non-flowery shoot. 
  • Remove any spent hardy annually if you don’t want them to take the seeds themselves. 
  • Plant autumn bulbs, such as colchicums, and nerines, to pots and borders. 
  • Prune the garden to clean before new growth appears in spring. If you’re not sure what your plants are, then a general rule of thumb is to prune after flowering, not before.
  • Remove garden bed weeds as soon as something appears. 
  • A thick layer of mulch will control small weed plants.
  • If you don’t want to take seeds yourself, cut down any seed-producing plants.
  • Check plants for mildew and cut down any affected parts.
  • Do not throw on a compost heap. Dispose or burn them in a trash bin.
  • Let the Lavender get a haircut after the flowers are blurred. Be careful not to carve much into the wood trunks. 
  • The Viola flowers are cool-weather flowers, so it’s perfect to plant them at the end of August. Because they’ll love the sunshine and gradually cool temperatures.

Vegetable gardening in August 

  • August is the best month to start your fall vegetable garden. Beetroot, Broccoli, Carrots, Potatoes, Lettuce, and other cold-weather crops can also be planted at this time. 
  • Soak the vegetable seed overnight before planting. Once planted, cover them with manure to avoid soil crusting. Mulch will continue to moisten the beds and provide shade during the initial establishment. Monitor and control insect pests that prevent good plant starts in your fallen garden.
  • Keep an eye on the damage to insects, slugs, and snails throughout the garden. 
  • Sketch where you have planted different vegetables in your garden so that you can help prevent disease by rotating your crops when you plant them next spring.
  • Take away old plants that have stopped production to eliminate shelter for insects and disease organisms. Replant sites with Chard, quick ripe Beans or Cucumbers, Leafy Green, etc.
  • The best time to collect herbs and flowers to dry and preserve is in the morning hours, 
  • Water plants plant deeply once or twice a week depending on heat and humidity.
  • If you have planted covering crops like Mustard and Lupin, now is the time to dig them. These plants will rot in a few weeks, adding nutrients and organic matter to the soil.
  • Plant Beetroot, Broccoli, Cabbage, Cauliflower, Kale, Peas, Onions, Spinach, Coriander, Parsley, Rosemary, Sage, and Thyme.
  • Harvest Brussels Sprouts, Broccoli, Cabbage, Cauliflower, Celery, Winter Lettuce, Mizuna, Parsnips, Spinach.
  • Sow Beans, Beetroot, Spinach, and Turnips seeds for the fall garden. Spinach can grow better if refrigerated for a week before planting seeds.
  • Broccoli, Cabbage, and Cauliflower transplants should now be fixed for the fall garden.
  • Now start planting the Lettuce and radish to fall.
  • Pinch the growing tips of the Gourd after getting a proper fruit set. It directs energy to ripen fruits instead of producing vine.
  • Brown and green stinking insects are active on Tomatoes and Chillies. They eat fruits producing yellow or white cloudy spots directly under the fruit skin. These spots become difficult but can be cut with sharp knives and will not affect the taste. Spray should contact stinkbugs to be effective.
  • Harvest and protect the Tarragon, Rosemary, Basil, Sage, and other culinary herbs. 
  • Remove all rotten or fallen fruits and leaves from trees, vines, and shrubs and dispose of them. This will help decrease the overwintering of diseases and insect pests that will harm your fruit plants next season.
  • Plant cold-weather crops including Spinach, Lettuce, Carrots, Beetroot, Broccoli, Cauliflower, Chinese Cabbage, Turnip, Kale, and Mustard. Keep the seedlings moist and mulch. 
  • Fallen leaves and old straw mulch are good sources of high carbon brown material. Water your compost pile weekly when you water the garden and turn it around regularly.

Herbs gardening in August 

  • August is a great time to take a semi-ripe cutting, which is a great way to start or grow your herb collection – easy, efficient, and affordable. The cuttings are taken at this time of year work well for a lot of plants in our herb garden, especially herbaceous plants like Mint and Oregano, evergreen bushes like Rosemary, and Sage, and even evergreen trees like bay.  
  • Remove dry or erasing leaves to help stimulate plants and monitor any signs of pests and diseases.
  • Seeds have already started to ripen, so if you have allowed one of your flowering plants to mature to save the seed, keep an eye on the seed’s heads. You want to collect them once they are completely mature and not green, but before the seeds naturally fall to the ground. Some of the seeds we are collecting or currently seeing include Poppies, Calendula, Coriander, Mullein, and Hollyhock.
  • Trim lavender plants after finishing flowers for the first time to encourage a second flush of flowers. Cut the trunks 1 to 3 inches below the flowers, but be careful not to cut into old wood, as it cannot grow back.

Trees and Shrubs care in August 

  • The end of summer is a great time to plant evergreen trees and shrubs.  New plants will have several months to grow new roots and beautify your courtyard this coming winter and throughout the year. Evergreen trees such as Pine, and Spruces can help save energy when planted on the northwest side of your home, provide welcome shelter for winter birds, and will be beautiful when covered with fresh snow. It is important to give evergreen water any week until the land is frozen, we do not receive an inch or more of rain.
  • Some flowering shrubs open at the end of summer but many new hard shrub roses will continue to open in October. 
  • Stop cutting evergreen trees and shrubs to avoid promoting new growth which may not be hard before the first frost. 
  • Fruit plants like Winterberries, Holly, and firethorns need to be watered regularly during dry spells to ensure that the berries mature and fall.
  • Don’t forget that trees and shrubs need water during extended dry periods.
  • Trim the bushes and evergreen into shape.

General plant care in August 

  • Clean weeds before setting up from cracks in paving and driveways. 
  • Prune the Wisteria by shortening all the long side shoots to about 20 centimeters in summer. 
  • Keep on deadheading the border plants, unless you want to collect their seeds. 
  • Remove the suckers from around the base of Roses or trees.  
  • Collect seeds and ripe seed beans from your favorite flowers and vegetables. 
  • Prepare soil for sowing or laying turf during September and October. 
  • Hunt regular snails to reduce population, especially on damp evenings.  
  • Turn manure to speed up degeneration. 
  • Rake up fallen leaves due to dry weather periods. 
  • Check the tree and tree stakes to make sure they’re not too tight around the trunks. 
  • Change broken glasses in greenhouses and fix the leaking shed roofs before autumn rains. Greenhouse guttering can also be tested to ensure it is not blocked from debris.
  • Plants that have grown substantially but are not at all ready for harvesting will need to be maintained. Especially when it is still hot and the weather is sensitive to dry periods. We recommend you consider a plant-water method itself. Like water in a bottle of wine that will keep your plants well hydrated when you are away.
  • When the weather is hot and there is a lack of rain, there is a risk of compost heaps drying up. If you want your compostable waste to continue to break into standard materials, make sure to water the compost pile occasionally and rotate it with a fork to allow exposure to the center and air.
  • At the end of the month, gardeners should start thinking about felling fruit trees. Like Apples and Pears to boost the growth of new fruits in time for next season.
