Radishes, turnips, beets and carrots can all be started from seeds in August. Chinese cabbage, broccoli, cauliflower and brussel sprouts can be transplanted in August and still have enough time to produce a good harvest.
Plants in the Cole or Brassica family are perfect crops you can plant in August. Broccoli, cabbage, cauliflower, kohlrabi, and Brussels sprouts all do very well in the fall. One very important thing to keep in mind is that you plant all of these plants from seedlings NOT SEED's.
Planting a Late-Season Garden
There are many crops you can plant well into summer (as late as mid-late August) and still harvest a sizable amount of food.
Some good candidates to plant now include hydrangeas, daylilies, lilies, sedums, ornamental grasses, peonies, and bearded iris. Just be sure you keep your new plants well watered if the weather is hot and dry. Mulching the beds also helps preserve soil moisture.
You can still plant flowers, too!
– all of the annuals that usually burn out by late summer. This way, you'll have a marvelous second flush of bloom and can cut armfuls for Labor Day! June and July are also good times to start seeds for perennials and biennials to bloom next spring.
Answer: Late summer (late August to mid-September) is an excellent time to plant many perennials. It is also a good time to move or divide perennials, such as peony, daylily, garden phlox, and oriental poppy.
Yes! You can still get a harvest from seeds planted in July as long as the plant's required days to maturity will happen before your region's first expected frost date. You can also give yourself a head start by purchasing young transplants from a nursery rather than starting your vegetables or herbs from seed.
Let's look at plants that love to be in warm soil and warm air, which is just what we need in July and early August: Bush beans, pole beans and lima beans like the heat and are great choices. The beans are easy to freeze or can for winter use.
Aside from times of extreme weather, roses can be planted at any time during the year. The extreme weather conditions that we advise against planting in are when the ground is frozen, water-logged or during a drought.
Technically, you can plant perennials any time your soil is workable. Practically, the best times to plant perennials are spring or fall. These seasons allow plants to get settled and grow new roots before summer's hot, dry weather arrives. Planting in summer is okay, but you'll need to water frequently.
When to Plant Black-eyed Susan. Set new plants out in the spring after all danger has passed or plant in the fall. The optimal soil temperature for germination is 70° to 75° F. Do not plant in the hot summer. If planting by seed, sow seeds about 6 weeks before the average last frost.
Adding new plants to your garden area during hot and dry conditions is not ideal, but it can be successful. The number one thing to remember during hot weather is WATER! Frequent watering will need to be done until the new plants are established.
Meanwhile, summer planting is also not ideal because of the high heat during this season. In San Diego, for instance, the temperature in August can hit 78°F. That's why the best time to plant roses in Southern California is either in spring or fall.
Passionflower is a perennial vine (meaning it comes back every year) that dies back in the fall; it needs rich well-drained soil and partial shade to full sun. With winding tendrils, this vine can climb vertical structures like trellises and armatures created from chicken wire or similar materials.
Just because it's the end of summer it doesn't mean that it's too late to plant in the garden. In fact, many plants — such as spring bulbs and perennials — need to be planted in the late summer or early fall months, depending on your zone, in order to generate enough energy to bloom in the spring.
The latest time to plant for most vegetables would be the second week in June with a short harvest time. If planting crops that mature within 50 days, you could plant those as late as the last week in June, but keep in mind the weather will be turning cooler, especially at night. Cool crops are best for late plantings.
Tip. Mid- to late-August is often an excellent time to plant fall flowers, as long as the weather isn't still so hot that the plants will suffer heat stress. But don't wait too late to plant, or you'll have a very short window to enjoy your flowers. Check the growing requirements for each plant.
