Plant these between August 1st & 30th:

Beans (Snap Beans)

Snap beans are a family favorite here in the Yardibles kitchen. These beans are easy to grow. Amend the soil with compost and plant the seeds about 8″ apart. Make sure to keep an eye out for cutworms, slugs, and snails if they are in your area.

Black Eyed Peas (Cowpeas)

We have been enjoying our black-eyed peas for over the last month here in the garden. If you haven’t tried these yet, you still have time. We love to add them to stir fry, soups, and stews.


August Garden Guide


You can never plant too many carrots, at least in our household. Some carrots are fast growers 30-40 days, and others like to take their time. All of them are delicious straight from the garden. Did you know that carrots come in a variety of colors from purple to red & even white?



Corn is always a fun crop to grow, especially for kids. You can grow a variety of colors and sizes in your own backyard garden. August is a great time to plant the three sisters – Corn, Beans & Squash.


Green Onions

Green onions are such a useful vegetable to grow in the garden. They are excellent on baked potatoes, tacos, and chili. We love being able to walk into the garden and harvest fresh green onions to add to a tasty family meal.


Set out Transplants August 1st – 15th


Between the 1st & 15th is the time to get your tomato transplants in the ground. When planted in August, you can be harvesting tomatoes up through the first frost.


Winter Squash

Your lance chance to get your winter squash growing for the year is the first two weeks of August.


Plant August 16-30th

All the plants listed above can also be planted in the last two weeks of August plus the list below. It is getting a little late to get your tomatoes & winter squash in, but if you are determined, I say go for it anyway.

Bok Choy

If you love vegetable stir fry as much as we do, you will not want to miss out on throwing some seeds in your fall garden. You may have also heard of this Chinese cabbage by the names Pak Choi or Pok Choi.



Did you know that 1 cup of broccoli has just as much vitamin C as an orange? As if there weren’t enough good things to say about this amazing superfood. It’s time to get your broccoli ON!


Brussel Sprouts

For some reason, this is the ONLY veggie that is not my favorite, but for others like my dad, you can’t get enough of them. If you are one of those people you can plant these anytime after the 15th.



Cabbage is another fall favorite around here. We love making homemade sauerkraut and other dishes. Check out some of these varieties you can try this year in your zone 9-10 garden.



We have an old family recipe that we grew up with that involves cauliflower. It is one of our family’s favorites recipes, maybe I will share it with you one day. Until then, if you love cauliflower, make sure get it planted this month. Check out the purple and cheddar colored cauliflower. These are fun ones to grow with kids.


Growing Celery in August in the Low Desert


Every gardener has a nemesis. For years, mine was celery. But once I got it started in my garden and let it reseed itself year after year, I now have an easy fall and spring crop to be proud of.



Chard is a dark green vegetable that keeps on giving. Plant some now in August and you will have large leafy greens into the winter and late spring. I have also had some that lasted right into the heat of summer.


Collard Greens

Collard greens are another versatile green to grow in your garden. These are great in stir fry, soups & stews or cooked up as a simple side dish.



Like all vegetables planted this time of year, cucumbers welcome the monsoon rains. Plant these between the 16th and 30th this month.


August is a great time to plant your kale out in the garden.

Besides, lettuce, Kale is my all-time favorite leafy green to grow in the garden. This dark, superfood can be eaten fresh in salads, cooked down like spinach, dried & powdered to sneak into your kid’s food, or made into Kale Chips (yummy!)



Kohlrabi, also known as German turnip or Cabbage Turnip forms an edible turnip-like bulb. The entire plant is edible from its roots to its leaves, although it is recommended to peel the bulb before eating.



Winter is on its way in just a few short months. Leeks are an excellent addition to soups, stews, and other winter comfort foods.


Lettuce, Head

If you are a beginner gardener, lettuce is one of the easiet crops you can grow. Head lettuce has more compact leaves that form a head similiar to cabbage. One common type of head lettuce you may be familiar with seeing at your local grocery store is Ice Berg Lettuce & Romaine.

Lettuce, Leaf

Leaf lettuce differs from head lettuce by its growth habit. Leaf lettuce has leaves that spread out and are not tucked in close to each other. They tend to be softer in texture and crunch than head lettuce but are excellent in salads. Leaf lettuce comes in a variety of colors and textures.



Mustard greens are a great zesty addition to any meal. These slightly spicy dark greens are full of vitamin A and C & K as well as other valuable minerals & fiber.



If you love pumpkin pie, you can never grow too many pumpkins. Whether you like to grow the giant ones or the funny looking ones, August is a great time to get in your last crop. This is a great crop to plant with kids.


Planting summer squash for fall harvest.

Summer Squash

You have a few more weeks to plant out your summer squash. Plant now in time for the monsoons for the best growth.



Turnips can be a love it or hate it type of veggie, but you never know until you try it. My mom would mix them in with mashed potatoes for a yummy healthy treat. Make sure when you purchase seeds that you check whether they are only turnip tops, or if they grow a bulb.
