How to Grow Zucchini
Zucchini grow in a large low structure and do take up quite a lot of space in the garden due to their large leaves. Choose a full sun location with at least 6 hours of sunlight a day. Zucchini can also be grown in pots and containers.
Zucchini are warm-loving plants and can be damaged by frosts. It may be best to plant your seeds in small pots or seed trays until your last frost has passed. Otherwise, Zucchini grow best sown directly into the soil. Plant your seeds as per the packet instruction as each variety and climate will have different growing suggestions. Once your seedlings have 4-5 leaves and your likelihood of frosts has passed, plant your seedlings in free-draining soil with plenty of compost. If you are growing Zucchini in garden beds, create small mounds of soil to plant your Zucchini seedlings on top of. Plant each seedling at least 1m apart.
When to Plant Zucchini
Plant Zucchini seeds directly in the soil during spring and summer. For early crops you can plant seeds inside in seed trays and plant outside once your last frost has finished.
Care/ Maintenance
Zucchini are heavy feeders, so it can be helpful to feed your plants with liquid seaweed or garden fertilizer every 2-3 weeks.
Mulch around your plants to protect the soil and retain moisture. Water your Zucchini at the base to avoid getting the leaves wet, as Zucchini can be prone to powdery mildew. Watering in the morning can also help to prevent this, as the leaves will have time to dry out and not sit wet for too long. If you do see white powdery mildew, remove the affected leaves and make up an organic spray with a mix of 9 parts water to 1 part milk. Spray this over the Zucchini leaves.
It can be beneficial to remove the older leaves at the base of the plant to increase airflow and prevent moisture from sitting around too long. Use sharp and clean secateurs to reduce the spread of any diseases.
Some plants may need staking or support as they grow.
Pollination/ Fruiting
Zucchini produce both male and female flowers on each plant for pollination. Our bees do a fantastic job at pollinating, so planting flowers nearby will help to encourage plenty of pollinators to your garden.
If your Zucchini are not reaching maturity and seem to shrivel and die prematurely, this may be due to a lack of pollination. You can manually pollinate your flowers by using a small paintbrush to dust the pollen of the male flower’s stamen (single flower with no baby Zucchini forming) to the female flower Stigma (flower with a baby Zucchini at the base). This can help boost your success rate and grow more Zucchini. This can also be achieved by picking a male flower, removing the petals, and using the pollen-covered stamen to transfer pollen to the female flowers. If you do notice pollination issues be sure to plant lots more flowers in between your plants to attract more bees.
Another reason your fruit may be dying off could be due to blossom end rot. This will cause the end of the Zucchini to go brown and start to rot before reaching maturity. This is due to a number of factors such as lack of calcium in the soil, feeder roots being cut or damaged, and most commonly, inconstant watering. During hot, dry periods, it is important to keep a regular watering schedule. Anautomatic timer will come in very useful. Mulching will also help retain moisture.
Pests / Disease
Zucchini is relatively pest-resistant. Protect young seedlings from slugs and snails. They can get some fungal diseases in humid weather. It is important not to wet the leaves to prevent powdery mildew from forming. If you do start to see some powdery mildew, remove the leaves (if it is only a few) or create a spray of 1 part milk to 9parts water and spray over the affected area. Once the fruits start to mature be aware of rodents or other animals finding your harvests.
How/ When to Harvest
Harvest your Zucchini when they are small (15-20cm long) and often. This will encourage your plant to produce more and more fruit. Use sharp secateurs to avoid accidentally ripping the entire plant out or snapping off part of your Zucchini.
Zucchini grow very quickly once the plant is established, so you may need to check every day or every other day for new produce.
If you want to harvest Zucchini flowers for eating, choose the male flowers. Otherwise, you will be reducing the number of Zucchini you get from each plant. Be sure to leave some male flowers for pollination, or harvest your flowers after manually pollinating the female flowers.
Reproducing
Zucchini seeds are the easiest way to reproduce. Let 1-2 of your best-looking Zucchini grow to maturity (until the skin is hard and cannot be broken with your fingernail). This will be when the seeds are mature and ready to harvest. Wash the flesh off the seeds and allow them to dry before storing it in a cool, dry, dark space.
Cooking and Using Zucchini
There are so many ways to use Zucchini and with just one plant, you will have plenty of opportunities to try many of them out! Below are just a few of the many ways to cook and preserve your abundant Zucchini harvests.
Celebrate summer with these delicious watermelon choc-tops. Indulge in a sweet treat without all the added refined sugars. These watermelon choc-tops can be made frozen for an iceblock or chilled in the fridge for a refreshing summer treat. If you don’t like biting into a frozen iceblock, the refrigerated versions may be the best for you. These were such a hit and will now be a summer staple in our house!
With just two simple ingredients you can quickly and easily make these Watermelon Choc-tops that are sure to impress! Sprinkle with edible flowers before the chocolate sets to add a little extra magic.
Watermelon Choc-tops
Prep Time: 5 minutes
Additional Time: 2 hours
Total Time: 2 hours5 minutes
Watermelon Choc-tops are the ultimate summer treats! Quick and easy to make using simple ingredients.
Ingredients
Watermelon
Chocolate buttons (or whatever chocolate you prefer)
Edible Flowers
Iceblock sticks
Instructions
Slice your watermelon up into Iceblock sized pieces around 1cm thick and place in a container in the fridge to cool while you melt your chocolate.
To melt the chocolate I place my chocolate buttons in a small saucepan and set it over another saucepan with water and allow the steam to heat it.
Once your chocolate has melted remove it from the heat.
Create a rack to hold your watermelon iceblocks by placing two sticks (or chopsticks or knives) across the top of a cup.
Push the iceblock stick into the watermelon pieces so that they are secured.
Spoon over your melted chocolate and sprinkle on edible flowers. I used dried cornflower. Carefully place your chocolate-coated watermelon upright on your makeshift rack by holding the bottom edge of the watermelon.
Place in the freezer to set. The watermelon will be frozen and ready to eat within 2hours. Or place in the fridge until the chocolate has set for the fresh version.
Notes
Both fresh and frozen are good! However, I do prefer the frozen ones.
The difference between the fresh or frozen versions is :
Fresh - Sweeter, very juicy, a little hard to eat.
Frozen- Mild watermelon flavour, not too sweet, need to be good with biting into frozen food.
Watermelon salsa is a refreshing and delicious addition to any summer BBQ. Serve with grilled Fish, Chicken, Fritters, Tofu, or Haloumi. This salsa is so quick and easy to make and looks so festive! Watermelon Salsa would be a perfect addition to summer entertaining.

10-12 Nasturtium leaves (or lettuce leaves) to serve (optional)
Watermelon Salsa
Instructions
Rinse your Zucchini and grate them into a bowl. Sprinkle with 1 tsp of ground rock salt (roughly 5-6 grinds) to allow the moisture to extract. Stir through, cover, and set aside for 10 minutes.
Finely chop your Herbs, Onion and Chilli.
After 10 minutes or so place your grated Zucchini in a sieve and squeeze out all the extra moisture.
Then in a clean bowl mix all your ingredients together and season well with salt and pepper.
Heat a pan on medium-high heat with oil. Spoon your mixture into the medium-sized pan and flatten it down a bit. Cook 3-4 minutes on each side or until crispy brown.
While your fritters are cooking, heat a small pan and fry off your sliced Haloumi until lightly golden.
Allow your fritters to cool slightly and serve on Nasturtium leaves with a slice of Haloumi and a spoon full of Watermelon Salsa.
Notes
Alternatively, serve your Zucchini Fritters with a garden salad and top with Haloumi and Watermelon Salsa for a Light and Refreshing Summer meal.
Watermelon jerky or dehydrated watermelon is a great way to use and preserve your leftover or excess watermelon. Some watermelon can grow to over 25kg! That’s a whole lot of watermelon to eat before it goes to waste. This recipe makes a delicious, chewy, sweet treat and helps stop any precious watermelon from going to waste.
Marinated in fresh mint and lime juice, this watermelon jerky is packed full of delicious summer flavours!
Watermelon, like its name suggests, has high water content. By dehydrating and removing that water content, you are left with a high concentration of natural sugars. This Mojito watermelon jerky recipe helps balance some of that sweetness and adds a delicious and refreshing flavour. When making this recipe you can do some with the marinate and some plain to work out which you prefer.
Mojito Watermelon Jerky
Cook Time: 1 minute
Total Time: 1 minute
Naturally, sweet watermelon treats 🍉
Ingredients
1/2 Watermelon
1 Lime
1/2 cup fresh Mint
Instructions
Rinse and finely slice the mint.
Add the juice and zest of one Lime to a bowl and mix through the mint.
Remove the rind and any seeds from the watermelon and slice it into strips roughly 1cm thick. If the strips are too thin they will break apart and be hard to remove from the tray. Too thick and it will take a loooooong time to dehydrate, so I have found around 1cm is a happy medium.
Lay your watermelon strips in a large shallow dish and pour over the lime and mint marinate. Gently turn over to coat. I like to do a mix of some marinated and some plain. Cover your dish and refrigerate for 1-2 hours to allow the flavours to combine.
Place your watermelon onto your dehydrator trays, ensuring you have a drip tray at the bottom to catch excess juices. I have found it is best to use fruit leather trays or parchment paper otherwise the jerky gets stuck to the metal grids. Dehydrate at 60 degrees Celsius until dry (This will take anywhere from 18-24 hours). To speed up the process, turn your watermelon strips over a few times during the process.
They should not be sticky to touch. The thicker parts that aren't quite dry will be a darker red colour. You may need to remove the dried watermelon and let the thicker slices dehydrate a bit longer. This will take anywhere from 18-24 hours.
Allow to cool and add to a clean, dry, airtight container.
Enjoy! 🍉
Notes
Please note that the Watermelon reduces significantly in size once dehydrated and has concentrated, high levels of sugars. Enjoy 2-3 pieces per serve as a treat or natural confectionary.

How to Grow Watermelon
Watermelon likes a full sun location, with approximately 6-8 hours of sunlight. Plant seeds when daily temperatures start to average 20-25 degrees Celsius per day (less for colder varieties). Watermelon does not like their roots being disturbed. So if possible planting them directly in the ground can be beneficial. Create 30cm high mounds of soil using rich compost and composted manure. Plant your seeds 1 inch deep on the top or plant your seedlings if you have germinated inside.
When to Plant Watermelon
Plant your watermelon seeds from Spring to early Summer. Watermelon can take a while to produce so it is a good idea to get them in the ground early. As soon as temperatures average 20-25 degrees Celcius.
Care/ Maintenance
Young watermelon plants will need regular watering. Especially in the height of summer. The leaves will curl up and notify you that they are too dry. Avoid watering the leaves as this can allow powdery mildew to form. It can be a great idea to put a stick or marker where you plant the seeds. Once the plant is established, it can be hard to see where the main stem and roots are to water correctly. Placing a marker will help you water the correct part of the plant for maximum efficiency. Cover your soil with mulch – pea straw or lucerne can be a great option as it will start to break down and feed your plants.
Feed your plants regularly (every 2 weeks or so) with a liquid seaweed fertiliser for an extra boost of nutrients.
Heavy rain or excess watering when the fruit is nearing maturity, may cause the melon to crack open. Keep an eye on your ripening melons.
Watermelon can also be grown vertically! Especially the smaller fruiting varieties. Plant them near a trellis or frame and move the vines as they grow to latch onto the frame. They have strong tendrils that will hold them in place. Once the fruit starts to form you may need to support the weight so that they do not snap and fall. A mini hammock under the melon using a stretchy, breathable fabric such as a stocking can be useful.
Pollination/ Fruiting
Watermelons require pollination from a male to a female flower to form fruit. If you have plenty of bees in your garden, they should be able to do this for you. If you notice small watermelons forming and then dying off, this may mean you have a pollination problem. This can be aided by using a small paintbrush to dust the pollen of the male flower (single flower with no baby melon forming) to a female flower (flower with a baby melon at the base). This can help boost your success rate and grow more watermelon. Be sure to plant lots more flowers in between your plants to attract the bees if you ever have pollination problems.
Pests / Disease
Watermelon is relatively pest-resistant. They can get some fungal diseases in humid weather. It is important not to wet the leaves to prevent powdery mildew from forming. If you do start to see some powdery mildew, remove the leaves (if it is only a few) or create a spray of 1 part milk to 9 parts water and spray over the affected area. Once the fruits start to mature be aware of rodents or other animals finding your fruit.
How/ When to Harvest
Harvesting watermelon can be tricky! And devastating when you get it wrong (be prepared it may happen from time to time..). Under-ripe watermelon will be bland and lack flavour, whereas, over-ripe watermelon will be floury and granular.
Some ways to determine if your watermelon is ready:
Look for the curly tendrils closest to the watermelon stem. They should turn brown and dry when the watermelon is ready.
A light knock on the watermelon, it should sound slightly hollow when ready.
Carefully roll the melon over and the part that was touching the ground should be turning yellow.
Reproducing
Watermelon seeds are the easiest way to reproduce watermelon. Choose seeds from your best mature melons. Wash off the flesh and allow it to dry before storing it in a cool, dry, dark space. Watermelon can also be grown from cuttings. Do this early in the season otherwise, the vine will not have enough time to produce before the weather gets cold. Cut a 10cm piece of a side shoots off. You want to let the main leader vine grow so do not cut this. Cut just below a leaf as this is where the roots will form. Place in a jar of water until you see some roots form. Then plant it back out into the garden. This is more for a bit of fun as you will get the best crops from direct-sown seeds.
Cooking and Using Watermelon

Preserving the Harvest
Watermelon is best eaten cold and fresh but sometimes we can’t keep up with their generous yields. Dehydrated watermelon is a great way to use up a lot of extra watermelons. Watermelon jerky is extremely sweet and could make a good substitute for natural lollies. Other ways you could preserve your watermelon are Freezing cubes, juicing and freezing cubes or making syrup or chutney.
Rainbow slaw not only looks amazing but it’s also packed full of nutrients. Just like planting diversity creates a healthy garden, eating diversely also has many health benefits. Each vegetable has different levels of vitamins, minerals, phytochemicals, dietary fibre, and antioxidants. This slaw can be adjusted to suit your seasonal produce – see the notes for other vegetables to try out. Rainbow slaw is very quick and easy to make and can be a delicious and wholesome accompaniment to any meal.
Rainbow Slaw
Vibrant and full of nutrients, this Rainbow Slaw is the ultimate Spring side salad.
Ingredients
1 cup shredded Red Cabbage
2-3 Carrots
1 cup chopped Lettuce
1 medium Red Beetroot
3-4 Radishes
5cm cube Butternut Pumpkin
2 TBS Sunflower Seeds
Dressing
3 TBS Coconut (or greek) Yoghurt
1 tsp Lemon Juice
1 Clove Garlic
2 tsp finely chopped fresh Fennel Frond or Parsley
1 TBS Water
1 Tbs Olive Oil
1/2 tsp Chilli Flakes
Salt and Pepper to season
Instructions
Rinse your veggies and clean off any grit or soil.
Finely slice the Cabbage using the thin-medium section of the mandolin. If you don't have a mandoline, you can either grate or finely slice using a knife.
Peel the Carrot, Butternut, and Beetroot (The skins dressed in olive oil and seasoned make delicious chips - see notes below).
Using the Julienne teeth on the mandoline, finely slice the Carrot, Radish, Butternut, and Beetroot into thin strips. Use a grater if you do not have a mandoline.
Roughly chop your lettuce into small pieces.
Add a little of each vegetable to a bowl so they are all mixed without having to stir through (otherwise the beetroot will turn everything red and you will lose some of your colours).
Drizzle with olive oil and a squeeze of lemon juice. Lightly toss.
To make the dressing, add yogurt to a small bowl. Then add crushed garlic, finely chopped fennel frond, lemon juice, water, chilli flakes, and salt and pepper to season. Stir well and taste. Add extra salt or lemon juice if needed.
When ready to serve, drizzle the dressing over the salad and top with sunflower seeds and edible flowers - I used nasturtium petals.
Notes
- Use vegetable skins from Carrot, Beetroot, and Butternut to make vegetable chips
Coat your skins in a light drizzle of oil.
Place your vegetable skins on a baking tray and sprinkle with a little salt.
Cook at 190 degrees celsius for about 5 minutes turning once halfway through. Keep an eye on them as they are so thin they will overcook easily.
Remove when they are golden and slightly crispy. They will also crisp up as they cool.
- Other vegetables that would be great in this slaw are: coloured Capsicums, Fennel, Nasturtium leaves, other Beetroot Varieties.
