Do you have areas that get very hot full sun and nothing seems to survive? These 22 heat-tolerant edible plants to grow in HOT full-sun locations will help you grow productive edible gardens. I’ve been growing food here in Perth, Australia for the last 10 years, and let me tell you, it was a big change and learning curve coming from the lush green of new Zealand.
Today, I’m sharing some plant ideas to plant in those super hot locations but keep reading to the end because it’s not just about what you plant but also when and how! Bonus tips on that, so you can turn your hot barren wasteland into productive edible gardens.

22 Heat-tolerant Edible Plants
1. Rosemary
Attracts bees π Has healing properties and is great for skin and hair care. Flavour enhancing culinary herbπΏ When I first moved here I wondered why so many houses had Rosemary hedges out the front – and it’s because it thrives on neglect and our poor sandy soils. Rosemary is a great heat-tolerant addition to your edible garden. Try making your own Rosemary Salt.
2. Strawberry Guava
Strawberry/cherry and lemon cherry guavas are really hardy, low-maintenance fruit trees, that produce bucketloads of fruit!
3. Mulberry
Another powerhouse perennial that survives on neglect – they grow super fast so you can use these as a nanny plant or a pioneer plant. If you have a barren hot area you could plant a Mulberry to get quick shade established and later on remove it or heavily prune if it gets too big. Mulberry also loses leaves in winter to let light in.
4. Lavender
Lavender is drought tolerant – a great pollinator plant with many medicinal (calming and sleep) and culinary uses. In my garden (which will be different with climates and varieties) Lavender flowers at the same time as my Feijoas so I have it planted in between them to attract pollinators and increase my Feijoa harvests.
5. Feijoa / Pineapple Guava
If you have been following me on Instagram or subscribed to my YouTube you will have guessed this plant would make the list π Low maintenance, super hardy, and produced plenty of food! Feijoas do taste better when they get 50 chill hours a year so they aren’t optimally grown here in Perth but they do grow well and are drought-tolerant. They are evergreen and super bushy so can be grown as an edible hedge. They are known to have fire retardant qualities which is very handy for hot dry climates. If you are looking to purchase a Feijoa, choose a named variety (such as Duffy, White Goose, Mammoth plus more) as these will perform better and produce fruit faster than generic seedling plants.
6. Passionfruit
Passionfruit is an edible vine that can be used to cover a fence, structure or grown over an arbor to create shade. This can help cool your garden down and provide delicious fruit. Passionfruit flowers can also be used to make calming teas to aid in sleep and anxiety. NOTE: Avoid planting a grafted variety the grafts takeover and become invasive,hard to get rid of, and don’t produce good fruits.
7. Citrus
Citrus like full sun and once established can thrive in hot environments. Avoid planting new trees before or during the hot summer so that they have time to get their roots established before the added stress of summer.
8. Lemon Verbena
A fragrant lemony scent that is similar to lemongrass. Lemon Verbena is great in teas, baking, and all the things!
9. Pomegranate
A hardy fruiting tree that thrives in hot environments.
10. Loquat
Loquats are hardy fruit trees that thrive in hot conditions. Loquats can be a pest plant because they grow so easily and birds spread the seeds so check with your local area.
11. Lilly Pilly
Part of the Syzygium genus is a great dense evergreen hedging plant with bright pink fruits. The fruits are edible and can be made into jams, sauces, and even sparking wine!
12. NZ Spinach / Warrigal Greens
NZ Spinach unlike most spinach can be grown over summer. Although not technically spinach it can be used just as you would use spinach. NZ Spinach grows as a tick edible ground cover to protect the soil and provide nutritious greens.
13. Malabar Spinach
Malabar spinach grows as a climbing vine and can be used to grow up structures and provide shade in summer. With succulent-type leaves, the Malabar Spinach does well in hot conditions but does not like frosts.
14. Quince
Quince is a hardy fruiting tree that thrives in hot conditions. Quince is great for making preserves such as jams, jelly, and chutney.
15. Zinnia
Zinnia is an edible flower that thrives in hot dry conditions. Zinnia has vibrant flowers in a huge range of colours. The great thing about Zinnia is that it produces nectar so it attracts a diverse range of pollinators to the garden such as bees, hoverflies, butterflies, and small birds. Zinnia is susceptible to powdery mildew so great for dry summers.
16. Sunflower
I love growing Sunflowers because they attract a huge amount of pollinators to the garden and you can pretty much eat the whole plant! I use the petals fresh in a salad or press to use on baking as garnishes. The seeds can be used on top of salads, to make oil, or to make spreads and the leaves are also edible. Sunflower stems can even be made into flour! Sunflowers also help remove toxins from the soil so they are a fantastic addition to a hot full-sun garden.
17. Figs
Figs are hardy edible plants that can easily be grown from cuttings. Figs are great for hot locations and the fruit can be used for jams, relish, baking, and just enjoyed fresh!
18. Olive
Olives grow well in hot conditions and also in pots and containers. They are beautiful-looking plants with their slim silvery leaves. Olives can be used to make oils and delicious preserves. Olive leaves also have many medicinal qualities.
19. Grapes
Grapes are great for growing over structures to provide shade to your garden and help other plants grow. Grapes are deciduous so they lose their leaves in winter to let light in and have full leaf coverage in summer to protect from the harsh midday sun. Grape plants have so many uses from fresh delicious table grapes to jams, preserves, and wine! grape leaves also have many uses in the kitchen.
20. Hollyhock
Hollyhocks are an edible flowers that can grow up to 10 feet tall! They attract 100 of pollinators to the garden and their height acts as a flag inviting them in. The leaves are also edible and can be cooked to make wraps. Hollyhocks are an annual so they will need to be planted again each year but are so worth it! They can be susceptible to powdery mildew.
21. Thyme
Thyme is a hardy herb that thrives in hot conditions. Thyme is very versatile in the kitchen and pairs well with tomato dishes, on pizza, and roast veggies. Thyme also produces masses of tiny white flowers that attracts an array of beneficial insects and pollinators. Thyme creeps over the ground so it makes a great edible ground cover plant.
22. Macadamia Nut
Macadamia nut trees can take a long time to start producing (5-7 years) but are really hardy and nuts are great additions to a homestead to make flour and milk from.
8 Tips for Successfully growing heat-tolerant edible plants
Many of these heat-tolerant plants listed are perennials and the reason perennials are so good for hot environments is that they have established roots and have time to get used to their environment. Annuals such as lettuce and tomatoes are planted new and have shallow roots so are more vulnerable to overheating.
Below are some tips to help you get your plants established and thriving through hot periods.
Focus on good soil with plenty of organic matter
Mulch, much, mulch
Have water available nearby
Avoid planting in hot weather (always check the forecast)
Provide temporary protection such as shade cloth or umbrellas during hot periods.
Grow nanny plants or pioneer plants (quick-growing trees that provide dappled shade in summer eg: grapes, mulberry, and deciduous fruit trees)
Plant new trees in pots until after the summer heat has passed
Plant densely – allow other plants to protect and shade each other and the soil.

Water is a crucial part of any thriving garden and during summer many towns will experience water restrictions and droughts. This can add more stress to an already difficult growing period. Water restrictions can sometimes mean you cannot use hoses, irrigation or you may have limited days in which you can use them.
Do you rely solely on rainwater? Your tanks may be getting low or you are just conscious about preserving the water you have. Here are some tips and tricks to get the most out of the water you use and keep your gardens alive and producing food.
Water-Saving Tipsfor Water Restrictions
Make sure you check with your local council to see which restrictions are in place.
π± MAKE ECO SWAPS | Use eco, greywater friendly cleaning products so that you can start reusing the water you use in your home out into the garden. You can easily find many greywater friendly products these days or recipes to make simple cleaning products with no nasties. Not only is it better for your health to stop using nasty chemicals but it is also better for the environment – where the water will end up eventually. Products such as washing powder, dishwashing liquid, hand soap, shampoo, spray and wipe and anything you mix in with water.
π± GET PREPARED | Place a bucket or large watering can at your back door or somewhere that is both close to your house and in the direction of your gardens. This way you will have easy, convenient access to offload any water you have used and keep it to use on your gardens. Inform your family or housemates of where it is and what should be put in it (water with no nasty chemicals). Getting kids involved is a great way to teach them about the environment and how to be water-wise.
π± COOKING WATER | Pour any water used in cooking into your watering can. Water used to boil potatoes, rice, pasta, veggies etc can all go into your recycled water bucket.
π± OLD WATER BOTTLES | Pour any old water from water bottles that you don’t want to drink into your recycled water bucket.
π± DISH WATER | Depending on how involved you want to get, you could try washing your dishes in a bucket or tub in the sink to capture the water (making sure you’re using chemical-free, greywater friendly products). You could also use a bowl or pot to scoop out the majority of the water from the sink and place in your recycled water bucket. Or for a long term solution, you could direct your sink or dishwasher drain directly into the garden. IMPORTANT: Greywater can hold some pathogens so it is important to only use it on fruit trees and non-edibles and not straight onto your veggie patch. Check your local council restrictions.
π± WASHING MACHINE | The same as above you can either put the drainage hose in a container or bucket (ensure it’s large enough and only clean, eco-friendly products are used) or direct the pipes straight out into the garden for a long term solution. If your laundry is next to a window or door you could have a water container with a tap set up off the ground that you can place the hose into and then empty it into your watering can as needed. IMPORTANT: Greywater can hold some pathogens so it is important to only use it on fruit trees and non-edibles and not straight onto your veggie patch. Check your local council restrictions. Also, be aware that clothing will release microplastic if you have synthetic clothing.
π± SHOWER AND BATH | Showers can use a lot of water if you don’t restrict the flow and length of use. Place a bucket underneath to capture as much of the wastewater as possible or if you have a shower over bath set up, put the plug in and scoop the water out after. Make sure you have set up your shower with only eco, greywater friendly soaps, face washes and shampoo. IMPORTANT: Greywater can hold some pathogens so it is important to only use it on fruit trees and non-edibles and not straight onto your veggie patch. Check your local council restrictions.
π± RAINWATER CATCHMENT | Another great way to get more water is to set up catchments to harness the water that runs off your roof surface. Whether that is your house, garage or garden shed you can direct downpipes into water storage containers to use on your gardens. Rainwater is the absolute best kind of water for thriving gardens. Mains water that is provided by the City has chlorine and other additives in it that can slow or restrict growth.
MORE WATER-WISE GARDEN TIPS
Now that you have more water to use in your garden it is important to distribute that water in the most efficient and effective way. You don’t want to waste any of that precious water by evaporation or poor soil structure.
π± SLOW AND STEADY | The best way to get your plants to effectively absorb the water is to slowly distribute it and allow the plant time to absorb it. If you simply pour it on and walk away a lot of water will spread and run away across the surface and not be drawn down to the roots.
π± WATER UNDER MULCH | If you have a thick layer of mulch and only a limited amount of water, it is a good idea to pull back some of the mulch around the plant and pour the water directly onto the soil. Mulch can sometimes absorb ALL the water and not leave any for the plants. Mulch is great for protecting the soil and stopping evapouration so once the water is on the soil, push the mulch back around to keep the moisture locked in.
π± TIME IT RIGHT | Timing is everything. Choose cooler times to water your plants such as the early morning or late evening. This allows the plants to absorb as much of the water as possible before the sun and heat evapourate it. I tend to water any plants that are prone to mildew such as pumpkins, melons, cucumbers etc early in the morning rather than at night. That way they have time to absorb the moisture but they will also have all day to dry out if any moisture has reached their leaves. The rest of my gardens I tend to water in the evenings.
π± IMPROVE SOIL | Poor soil structure will be so hard to keep well watered as it will just let the water runoff or filter away. Sandy soils can become aquaphobic and be basically waterproof. Clay rich soils will become hard and compact restricting water flow to the roots. The best way to improve soil structure is to add fibre to your soils. Adding fibre means adding more plant matter by either compost of composted manure. Compost rich soil will retain more moisture and feed your plants. Healthy well-feed plants won’t require as much watering as their roots will be more developed and widespread to capture water more effectively.
π± SELECTIVE PLANTING | If you often have water restrictions or know there is likely to be a real water shortage in your area then make sure you are selective in what you choose to grow. Some plants will require more water than others so do your research and select plants that will work best for your conditions. Plants such as watermelons, tomatoes, cucumbers and lettuce will require a lot more water than plants such as chilli, natives, citrus, corn, sweet potato or mini eggplant.

When I first started gardening here I remember googling ” how to keep plants alive in a heatwave?” π Welcome to Perth summer gardening! I have always struggled with how hot it gets here in Perth in summer. After 7 years here, the 40degree days don’t get any easier! We have a large amount of thermal mass at our house with concrete and paved areas so it can get so hot in my garden! One of the main reasons I decided to make pallet planters on wheels was to be able to grow more food during the hot summer months by being able to have them undercover on hot days. Watch how we made them here.
How to keep plants alive in a heatwave
If you are experiencing a heatwave or have days of hot weather ahead of you, here are a few tips I use to try and get my plants through!
π± WATER | Give a good deep water early in the morning. This will allow time for the moisture to reach the roots before it evaporates.
π± SHADE | If your plants are in containers move them undercover or to a shady area of your garden. Otherwise, try and rig up some temporary shade using shade cloth or even umbrellas to keep the direct sun off your plants during the hottest part of the day.
π± PROTECT THE SOIL | Ensure you have a good layer of mulch or ground cover over your entire garden. This will protect the soil from being exposed to direct sun and reduce the amount of water loss through evaporation.
π± BUILD SOIL | This is something that should be continually worked on by composting and adding more fibre and leaf matter to your soil. Sandy soils like we have here in Perth allow all the water to drain away and can become severely water-resistant. But by consistently mulching, composting and adding green matter, you will not only grow strong, healthy plants but also protect your plants from future dry spells. Healthy soil is key!
π± REPLENISH | As the sun goes down and the temperatures start to drop again, give your plants another well-earnt drink. This should help their leaves perk back up again.
π± SAVE SEEDS | If you notice a certain plant seems to survive better than others in hot weather, make sure you save the seeds at the end of the season. That way you can futureproof your garden by growing strong plants that you know will grow well in your exact climate.

Are you growing Zucchini but the fruit seems to shrivel and die before being ready? If so, you may have a pollination issue. Hand-pollinating Zucchini is super easy to do once you know how. Today I will share 4 east steps with images so you can maximize your Zucchini harvests! This also works with Pumpkins, Melons, and Cucumbers.
Step 1: Identify a Male and Female Flower
Firstly, to hand pollinate Zucchini you need to know how to identify the male and female flowers. The best time to do this is early in the morning when the flowers are open.
Female Flower
The female zucchini flower has a small fruit at the base.The centre stigma of the female flower has multiple parts to form a circular shape.
Male Flower
The male flower has just a plain stem and flower with the centre stamen a single point covered in pollen.
Generally, the plant will produce a bunch of male flowers first which is nature’s way of attracting pollinators to the garden. Then it will alternate between male and female. I like to plant a few of the same variety as sometimes you can have female fruit but no male flowers open. Early mornings are best because the flowers will be open and then they will close up to capture the pollen.
You can either use a paintbrush to simply transfer the pollen from the male stamen to the female stigma but I find it easier to remove the male flower and use that to transfer the pollen.
Step 2: Pick a male flower
Pick the male flower and remove the petals.
Step 3: Dab pollen onto female Stigma
Then you are left with a pollen-covered stamen to transfer onto the female flowers.Transfer the pollen onto the female flowers to hand pollinate Zucchini.
This will make sure your zucchini are getting pollinated so you can enjoy the abundant crop!
This method can be used for other fruiting vegetables such as pumpkins, melons, cucumbers. I tend to use a small paintbrush for the melons and cucumbers though as the flowers are much smaller and delicate.
It is also important to try and attract wildlife to your garden for natural pollination, to find out what flowers to plant, click below.
