after a long hot summer September is the time to bring your Arizona Garden back to life the slightly cooler mornings and evenings make this the perfect time to transition your garden from Summer to fall whether you want to plant new crops or just get your hands in the dirt this is the month to make it happen I’m Angela from growing in the garden my Garden’s in Mesa Arizona I want to help you succeed even if you’re gardening in tough conditions don’t want to write all of this down everything’s available in these planting calendars on my website I also have a what to plant article for every month of the year September is the perfect time to get one last round of warm seasoned crops in the ground that warm soil helps the roots grow fast here’s what you should plant this month this is a good time to plant beans I’m planting lima beans our favorite Dragon tongue beans and edamam is another excellent choice to get in the ground this month it’s time to plant cucumbers from seed or transplant and cucum melons if you haven’t started them indoors look for pepper eggplant and ground cherry transplants plant etoy onions and shallots you can do shallots from transpant like this from bulbs or from seeds you can get a quick crop from summer squash either from seed or transplant tomatillos make sure to get two for pollination and tomatoes let me show you how to plant them want a bumper crop of tomatoes this year before you plant a men the soil with compost and lots of worm castings plant your Tomatoes about 2 ft apart so they have room to spread in this 8ft bed I’m planting four tomatoes right down the middle give those Tomatoes something to climb I’m adding another fryer trellis right down the middle of this bed when it’s time to plant cut off the bottom leaves and bury it nice and Deep Roots will grow along that entire stem a stronger plant means more Tomatoes if you don’t have enough room to go deep you can bury it sideways as well but go deep if you [Music] can cut off any blossoms for the first couple of weeks and let them focus on growing nice Deep Roots September is a great time to plant potatoes get your oil ready by adding in some compost and worm castings each potato should have at least two eyes those little sprouts plant each potato about a foot apart and because it’s still warm I’m planting them 3 in deep the soil is cooler down there keep them watered but not too wet once the Sprouts pop up I’m going to cover this with a thick layer of straw to keep those potatoes from turning green and becoming bitter as the weather starts to cool down hopefully in mid-september it will be time to start cool season crops keep an eye on the weather once temperatures begin to cool and the nighttime lows are consistently in the 70s you’re good to go arugula beets and bok choy broccoli cabbage kale and cauliflower you can plant from seed or transplant turnips carrots and radishes these root veggies do best started from seed greens like Swiss chard lettuce and spinach use transplants for this one but use seeds for these they’re less likely to bolt celery plant from transplants it is slow to start from seed peas and green onions try my favorite super sugar snap peas this year you won’t be disappointed did your garlic come in the mail pop it in the fridge until it’s time to plant next month if you want homegrown sweet strawberries in Arizona midep is the time to plant before you plant add compost and worm castings to the soil give each plant about a foot of space it’s nice if you can dedicate an entire bed to strawberries and they have their own space they may need more water than some of your other plants the most important thing when planting strawberries don’t bury the crown that’s where their leaves meet the roots and all the new growth comes from keep them well watered and pick off any flowers that form for the first few weeks also snip off those Runners and you can use them to make new plants all these Runners will take too much energy from the plant this Runner already has some Roots developing it’s a good candidate to pot up and make a new plant September can still be hot if you’re going to plant cool seasoned crops here’s a few extra tips make sure that you’re planting in good soil take the time to harden off your seedlings so they’re used to conditions outside plant seeds a little deeper so they don’t dry out and the soil is cooler plant at the end of the day so the plants can settle in overnight when it’s cooler provide extra shade Mulch and water well want to add some color and pollinators to your garden here are the flowers you can plant in September early in the month you could plant maragold and all of these once those nighttime temperatures start to come down you can plant snapdragons verbina and all of these September is also the time to start seeds indoors here are the essentials to remember when you’re starting seeds indoors use seed starting mix it’s different than regular soil and makes it easy for for the seeds to germinate fill up clean seed starting trays with the soil and make sure it’s hydrated plant seeds at the proper depth the seed packet should tell you how deep to plant plant two or three seeds per cell and thin them out pretty soon after they sprout top with a thin layer of vermiculite this helps hold in the moisture and keep down the algae don’t forget to label it so you know what you planted put them someplace where they get lots of light grow lights are essential the light from a window is not enough water from the bottom and keep the soil hydrated but not soggy when seedlings emerge thin to the strongest seedling that gives them plenty of room to grow a fan helps the stems grow stronger once they have a few sets of leaves start hardening them off so they get used to the outdoors and then you can plant them outside this month you can start veggies like kale broccoli and cabbage indoors look at all the other seeds you can start indoors in September here are the flowers you can start indoors in September September is an exciting time in the Arizona garden with the right planning and Care your garden will be ready for the cooler months ahead what are you planting this month let me know in the comments and I forgot the rest the lawyer husband and me is like not every anytime you use very are you sure you want to use very I’m just going to take that part out okay look how pretty the sky is oh my gosh

  1. I started all my brassicas last week, tomatoes, peppers and onions last month. I have more zinnias, cosmos and 4 o’clocks hardening off to plant this weekend. I’m trying to focus on flowers to plant this fall for spring. I started echinacea, aster, pincushion, primrose, snapdragon, dahlia, Gazania, African daisy, and alyssum. I’m in the west valley. When is the best time to start cardinal climbers from seed indoors? Love your videos! I’ve learned a lot since I started gardening about 4 years ago!

  2. Planting tomatoes and bell peppers. Just started hardening off geraniums I grew from seed. Boy do they need to get out of the seed trays. Thank you for all your knowledge and help

  3. Thank you Angela, Nor Cal 8b 9A, planted lots of these things today. Just used seeds that I had on hand, some may bolt as it will be warm for a while here. But if they bolt , it’s chicken food!

  4. I have my bed ready to plant radishes, snow peas, carrots, broccoli, rutabaga, lettuce, spinach, cucumbers are getting 1st true leaf, then garlic in Oct

  5. My I’itoi onions are sprouting and it’s so exciting!!! Would have not learned about these without Angela’s channel

  6. What is your favorite local nursery for vegetable plants? I live in Mesa, and I didn't know you could find cucamelon transplants.

  7. 4 weeks ago I planted some cucamelon seeds indoor but I had to travel and my 6 plants died 😢 can I planted cucamelon and cucumbers seeds outside?

  8. Questions : My tomatillos never fruited , even with hand pollination, I do have 3 plants. What am I doing wrong? is it still too hot?

    2nd question when can I plant rhubarb? do I start indoors? and when?

  9. If I don’t have the means to start seeds indoors, is it possible to do it outdoors in shade? It’s still in the 100s where I live. I’m in zone 9b

  10. I started broccoli and brussels inside so I could set out mid september. They all came up but the stems are like 4 inch threads and they all fall over and eventually wilt away. I set a fan to blow gently on them several times a day to help strengthen them but nothing has worked! What could I do differently?!

  11. I have three types of broccoli, three types of cauliflower, dwarf tomatoes, salvia, snapdragons, petunias, and dianthus from seed, they are setting their second set of true leaves. Planning to plant beans, cukes, and melons just to see if I can get them to harvest before frost since we are having such a long drawn-out summer! Lettuce, spinach, carrots, turnips, beets, rutabagas and maybe kohlrabi once the night temps lower some more.

  12. I started onion seeds last month and a few brussel sprouts indoors. Although I just came down with COVID, I planted Broccoli and Cabbage yesterday indoors. I'm hoping to feel well enough today to plant cauliflower indoors.

  13. I am direct seeding carrots and chitted potatoes. Brassicas and Legumes will do double duty as crop to eat and soil amendment. Monsoon tomatoes and peppers are already in and flowering. Spinach will be a companion for strawberries. This is my second year and I did not do a very good job keeping the Chandler plants alive and have sweet sensation plugs on order with early October delivery.

  14. I have a VERY small containor garden at my work. I recently up potted my orange tree and am thinking about planting carrots and spinach around the border. Beyond that, ive got a pepper plant, next to my behemoth basil that made this summer look ezpz with how wild it went, and a whole bunch of lavendar, rosemary, zinnia's, and zincas in the big pot next to it. My crew universally wants a bunch of peppers so im gonna add 3 into this big pot i have and hopefully get a dozen or two peppers. Beyond all that, depending on my budget, i would love to add strawberries.

  15. Your rannuculus are so beautiful! Would you recommend avoiding planing these with a dog and small children at home?

  16. I live in Mesa AZ…do you have a preference on wood or metal raised planters. Will the metal ones generate too much heat?

  17. Charles Dowding would disagree with don't bury the crowns. He claims as long as you use compost that the compost will shrink and disappear before it ever hurts the crowns. Again that's Charles Dowding in the the UK and not Angela in Mesa Arizona 😊

  18. Which strawberry and tomato transplants have you had the most success with in September? Looking forward to planting! 🌱 🍓 🍅

  19. Hi! I wonder if I can / how to grow pumpkins so they are ready by mid September / early October. This year I had some watering/shade deficiencies and all my pumpkin plants di3d. 😢
