To Do in the Garden: August 2024

And it’s August.  And it rained the entire month of July (11.83” in my rain gauge), so the grass has grown out before I can clean the mower and put it away.  The weeds…well. They’re being weeds.  The Accidental Cottage Garden (ACG) is a mostly perennial garden full of domesticated weeds.  It took a hit in June from the lack of rain.  There are real weeds out there to be pulled, but there are also Olympic Games to be enjoyed.  Weeds will still be there after the Olympics.  Fortunately, I can type between events or else this calendar might have to wait until after the Olympics, too.

No?  I must do it now?  Sigh… Okay.  If you insist.  In a minute.

As mentioned above, the ACG (what’s left of it) is rather pleased with the month of rain.  There are ten genera in bloom right now.  The coreopsis (C. lanceolata) doesn’t know quit nor do the black-eyed Susans (Rudbeckia hirta).  Both have persisted through drought and deluge to keep the yellow going.  Gold medals for them.  Silver for the longest bloom time goes to the Dakota mock vervain (Glandularia bipinnatatifida) whose dainty purple flowers can get lost amongst the taller species, and the foliage is dainty and of great interest, too.  Bronze is awarded to the purple cone flower (Echinacea purpurea).  I know, with a tie for gold there shouldn’t be a bronze.  You award medals your way, and I’ll do it mine.

Moving on to the honorable mentions; The gallardia (G. pulchella), balloon flower (Platycodon grandiflorus) (Doing a re-bloom after timely removal of old blooms), daylily (Hemerocallis x August Flame), evening primrose (Oenothera lamarckiana), and the two reseeding annuals, French marigold (Tagetes patula) and zinnia (Zinna elegans) all deserve this honor.

Hard to believe that these beauties are representing the Honorable Mention category: the daylily ‘August Flame’ is true to its name while the balloon flower seems nearly ever-blooming. (Image credit: Gary Crispell)

Calendar?  What calendar?  We already discussed this.  There are Olympic Games to watch.  Team USA to cheer on, and you want a calendar.  Sheesh.  Well, I did say I’d do it, so if you really want to go out in the heat here are many things to keep you sweat-covered and happy.

Lawn Care

Look for signs of grubs—smallish patches of yellowing or brown turf.  Dig around in one of them and if you find a grub treat the whole lawn with an appropriate insecticide.

Late in the month, prepare any areas that need seeding with cool season grass seed (tall fescue/bluegrass).

Fertilizing

Give strawberries a dose of nitrogen fertilizer.

DO NOT (as in DON’T) fertilize any trees or shrubs until the weather turns cold and stays that way for a while.

Planting

So, you like to start your own plants from seed?  Here’s an opportunity for you.  Sow flats of pansies now to be transplanted in late September.

Perennials such as hollyhocks (Alcea rosea), delphiniums (D. elatum), and Stokes asters (Stoksia laevis) can be direct seeded now for a bloom show next year.

Repot some house plants.

Plant a fall garden of beets, cabbages, cucumbers, kale, kohlrabi, lettuce, mustard, radishes, squash, turnips, and rutabagas or some combination thereof.

Pruning

No!  Except in case of emergency (hurricanes and severe thunderstorms) do not remove any pruning equipment from its storage facility until late November.

Spraying

See “SPRAYING” for July.  The same sap sucking little…critters—spider mites on coniferous evergreens, lace bugs on azaleas and pyracantha, and aphids on everything else.

Continue with rose, fruit tree, and bunch grape spray programs.

Check cruciferous vegetables (broccoli, cabbages, cauliflower) for worms and look for borers on squash.

Spray only when necessary.  Always identify the pest and apply the proper pesticide.

Always read the label and follow the instructions.

Propagation

Cuttings can still be taken from shrubs.

More Things for August Heat Lovers to do Outside

Update your landscape plan to include changes you intend to make this fall.

Harvest Irish potatoes.

Start composting or turn the pile.

Go to a baseball game.

Hydrate and take breaks from the heat.

It’ll be fall before we know it.

2024 Seed Starters Taste Test: Revealing the Best Tomatoes and Peppers

By Bev Tisci and Melinda Heigel, NC State Extension Master GardenerSM volunteers of Durham County

Taste testing has a centuries-long history. Ancient Egyptian rulers and Roman emperors had “official tasters,” who were tasked with ensuring food safety. In the early twentieth century, the USDA employed taste testers as a way to bring overlooked agricultural products into the American diet like soy, mung beans, and lamb. And in 2024, Durham County has a crack team of Master Gardener volunteers growing, tasting, and analyzing tomatoes and peppers so they can bring you the best of the best.1

Creating Seed Starters and Taste Testing

After volunteering for her first annual Backyard Treasures Plant Sale as a freshly-minted Durham County Master Gardener, Bev Tisci noticed that the sale was focused mostly on ornamentals. She saw an opportunity and volunteered to head up a group who would focus on increasing the number of vegetable plants offered in future sales, thus the birth of the Seed Starters. Tisci and her team painstakingly grow from seed all the vegetables we offer at the annual sale–in the 2024 sale over 1,200 plants! This group also helps train and mentor Master Gardeners in best practices for growing from seeds.

But the work of the Seed Starters doesn’t just begin with sowing seeds in February and March for the April sale; it begins in July when the group comes together to analyze the tomatoes they grew in their own gardens over the summer. The taste testing event features varieties they sold to the public, old-time favorites, and new finds they’ve never tried before. The result? The winners of the testing will make the list for the next year’s sale.

Growing seeds indoors can be a solitary pursuit, so Tisci started pulling the group together for casual tastings many years ago. As the group expanded and our plant sale grew, the testings have evolved to become more scientific–while just as yummy and fun. Now the group blind taste tests their vegetables, because as Tisci says, “When you don’t know what tomato you are tasting, the results are often different than you’d expect. There is always a chance for a surprise. You might pick something you wouldn’t have otherwise!”

Putting the Tomatoes (and Peppers) to the Test

Tisci sets up the event by creating numbered tent signs for each sample and evaluation sheets where tasters rate each tomato on appearance, texture, and flavor. They also ask the important question, “Would I grow this again?” They discuss other factors like ease in growing and disease resistance. With her years of experience in the garden, especially growing tomatoes, Tisci says, “People are always looking for heirloom tomato taste, but they also want protection from the diseases that are common here in our hot, humid climate.” In her mind, the combination of taste, disease resistance, and high yield makes a variety a clear winner.

While tomatoes have always been the star of the taste-test show, this year the group introduced both sweet and hot peppers to the table. Peppers are popular at the plant sale, so it’s likely this veggie-come-lately may appear in future tests and be subjected to more rigorous evaluation.
