Gardening in sandy soil can be a challenge, especially in hot, dry climates. Sandy soil drains quickly, lacks nutrients, and struggles to retain moisture. However, by choosing the right plants, you can naturally improve soil health while also growing food. In this post, I’ll share five of the best plants to grow for mulch and improve sandy soil, all of which are fast-growing, drought-tolerant, and multi-functional. These plants help build organic matter, retain moisture, and create a thriving ecosystem in your garden.
Pigeon pea is a nitrogen-fixing shrub that grows quickly and thrives in poor soil conditions. This makes it an excellent pioneer plant for mulching to improve sandy soil and support other plants in your garden.
Benefits of Pigeon Pea:
Fixes nitrogen, enriching the soil naturally
Produces edible, protein-rich peas
Attracts pollinators and beneficial insects
Provides dappled shade for smaller plants
Offers abundant biomass for mulch and soil improvement
Works as a windbreak and shelter for small birds and insects
Pigeon pea is a short-lived perennial (4-5 years) and can be used to establish a garden while building soil fertility.
Feijoa, also known as pineapple guava, is a hardy shrub that thrives in drought-prone and sandy soil conditions.
Benefits of Feijoa:
Tolerates drought and poor soil
Produces delicious, fragrant fruit
Provides dense foliage for wind protection
Low-maintenance and easy to grow
Can be used as a hedging plant to protect other crops
Feijoa is an excellent addition to sandy-soil gardens, offering both food and improved soil structure. They grow so much each year, which provides a consistent supply of green material to mulch. This is currently my top producer for mulch in the garden, and I use a mini mulcher with the Ecoflowbattery pack to give me cordless solar power anywhere in the garden.
Cassava (Manihot esculenta)
Cassava is a tough, resilient root crop that thrives in hot, dry climates and nutrient-poor soil.
Benefits of Cassava:
Grows well in sandy, well-draining soil
Produces large, starchy tubers that can be boiled, fried, or made into flour
Fast-growing, reaching 2-3m tall in one season
Drought-tolerant once established
Leaves are edible when cooked
Chop-and-drop plant for mulch and soil improvement
Helps prevent soil erosion with its strong root system
Cassava is an excellent survival crop that helps build soil health and provides a reliable food source.
Mulching for the win!
If you’re gardening in sandy soil, these five plants to grow for mulch will help improve organic matter, retain moisture, and build long-term soil fertility. By growing multi-functional, fast-growing plants, you can create a thriving, resilient garden—even in harsh conditions.

Learn how to grow Feijoa and what to make with their abundant crops! Feijoas or Pineapple Guava (Feijoa Sellowiana) are an abundant-producing fruit tree with green, sweet-tasting fruit. The trees are evergreen with dark green and silver foliage. Feijoas are easy to grow and, due to their thick foliage, they make a great screening tree or edible hedge!
This fruit tree is a prolific producer and can grow in a range of climates from temperate to subtropical, but grows best from zones 8-11.
Prune for size in autumn. Keep well watered in summer when fruiting.
FERTILISE
Feed with compost and keep well mulched.
PESTS
Rats, fruit flies, birds, guava moth, possums, scale.
HARVEST
Ripe when they fall from the tree. Collect daily.
REPRODUCE
Can grow from seed but best results are from grafted plants.
Why Grow Feijoa?
Here are some of the many reasons to grow Feijoa
It produces in abundance!
It is self-fertile
Evergreen – ornamental all year round
Delicious juicy fruit that are sweet with a perfumey flavor
Green fruit, which is harder to see from pests
Hardy tree – easy to grow
The whole fruit is edible!
Flowers are edible
Foliage is said to have fire-retardant qualities
Drought tolerant
Dense foliage can be pruned into a hedge for screening areas
Popular Feijoa Varieties
Feijoas are commonly sold as seedling plants under the name Pineapple Guava or Feijoa Sellowiana these will perform with mixed results and can take 6+ years to start fruiting. Choosing a grafted or named variety will offer a quicker-producing tree that will be true to type. Varieties will vary from country to country.
Duffy – Medium – large-sized fruit. Popular all-around variety.
White Goose – Large fruit with juicy white flesh. Early season fruiting that can last quite a long time.
Mammoth – Large round fruit with thick wrinkled skin. Can benefit from a pollinator tree. Tall upright tree.
Apollo – Medium – large oval fruit. Smooth light green skin. Tall upright tree. Semi-self-fertile – benefits from another pollinator tree.
Unique – Medium-sized fruit. Smooth, juicy, and sweet. Starts fruiting from a young age.
Triumph –Medium-sized fruit. Slightly gritty but good flavour. Late season bearing.
Nazemetz – Large oval/pear-shaped fruit. Smooth skin with sweet flesh. Self-fertile but will bear heavily with cross-pollination.
QUICK TIPSON HOW TO GROW FEIJOA
Choose a named variety (x2 different ones for bonus pollination)
Choose a sunny location
Add plenty of compost
Mulch
Ensure plenty of water during fruiting (summer)
Fruit is ready in Autumn
When to PlantFeijoa Trees
Plant your Feijoa plants in Spring or Autumn to avoid added stress from summer and winter temperatures.
How to GrowFeijoa
To plant your Feijoa, pick a sunny spot, they like full sun for 6-8 hours at least. And quite a bit of space, as these trees will grow quite large (2-5m). You can prune them back heavily though, so it’s not a major issue. They will also grow well in a large pot.
Dig a hole twice as big as the pot and mix a little compost in with the soil. If your plant has tightly bound roots, free them up before planting them out. Firmly pack the soil back around and cover it with mulch. Just pull back the mulch from the trunk so you don’t rot the trunk. Feijoas have shallow feeder roots so keep weeds and plants at a minimum under the tree line.
Give it big water! Now you basically don’t have to do anything for the first couple of years except keep it watered, especially during the dry season. You may get flowers in the first year or it makes take a couple of years until it is established enough to put out flowers. It flowers in spring and the fruits are usually ready and ripe in Autumn.
How to Care and Maintain Feijoa Trees
Feeding
Once your tree is established and starting to flower and fruit you can look at more fertilizing and watering. You can feed your plants near the end of winter, spring, and summer with compost or worm teas, or liquid seaweed. I don’t do a lot of feeding but I do chop and drop the prunings and add layers of mulch each year.
Watering
Another key tipis to ensure your plants get plenty of water during summer and late summer as the fruits are developing. This is something we struggle with here in Perth because we basically get no rain in summer. This last summer was so dry in Perth, and my trees were loaded with fruit. I obviously didn’t water them enough for the amount of fruit they had and the results are a strange hollow center. The fruit still tastes delicious, just not quite as juicy as it should be.
So I will have more mulch and more water next season. From memory, I was only hand watering max twice a week, and it was extremely hot here, so I’m not surprised really.
Pruning
Once your feijoas have finished fruiting, and you have picked up all the dropped fruit. It can be a good time to prune your trees if you want. I like to prune mine each year so that the fruit is always within reach. Otherwise, it ends up over the neighbor’s fence or is bruised from falling so far to the ground. Feijoas love a prune and it can actually improve fruiting. I cut back about 20-30% each year and I find that it grows back about that much so my trees stay relatively the same height by doing this.
Plus, by cutting back 20% of the tree, I get a whole lot of green material to chop and drop. In my food forest-style garden, I don’t remove anything so all prunings go directly back into the garden. I prune using hedge shears or loppers for larger branches and then run them through my small mulcher. You can also chop them into small pieces, then lay them around the trees. This will break down and act as a natural fertilizer.
Pollination
You may notice lots of small birds in your trees when they are flowering. Don’t worry as they are helping pollinate the flowers. They harvest the nectar and also eat the petals but generally allow the main flower to stay put and fruit. Bees and small birds are the main types of pollinators.
One tree will still perform amazingly as they are self-fertile but having multiple just increases your harvests. It can also extend your season. Meaning different varieties take longer or shorter to flower or ripen and you can get extended harvests.
One thing to note is that feijoas ripen quickly and in bulk. So they come in hard and fast.
Pests / Disease
Rats and possums will love your fruit, and also parrots and birds. You may want to net or bag fruits if you are worried. I definitely have rats and parrots but so far I haven’t needed to bag fruit as they are doing minimal damage to my large harvests. Fruit flies and guava moths are also a problem in other areas. Again, this would mean you need to bag the fruit or net the tree when the fruit is young before they get stung.
How/ When to HarvestFeijoa
Now comes the fun part – harvesting. How do we tell when the fruit is ripe if it remains green? Well, it falls off the tree. So each morning, you can go out and pick up all the fruit from the ground. It is important to pick all the fruit up because otherwise, you will attract pests like rats and possums, or fruit flies. Feijoas do continue to ripen off the tree so you want to eat them quite quickly or use and preserve them. I like the tartness of fresh feijoas, and they get sweeter and more perfumy as they ripen, which is why I never like feijoas from the stores, as I find them too overripe.
Most people will cut the fruit in half and scoop out the inside to eat but you can eat the whole fruit. Especially when they are quite ripe the skin is sour and the inside is sweet it has a nice balance.
Reproducing
Ripe feijoas may have small brown seeds inside. These can be planted in moist soil. Feijoas do not grow true to type from seed so they may produce fruit different from the one you saved the seeds from.
Ways to cook and use Feijoa
Feijoas are delicious when eaten fresh off the tree. You can eat the whole fruit or cut it in half and scoop out the insides. Once they fall from the tree, they may still be a little tart. Allow them to ripen for a few days, and they will become softer, sweeter, and juicier. However, they will continue to ripen and become over-ripe. Fruit flies may also find them on the bench, so I like to keep them in the fridge.
Feijoa flowers are beautiful, and the petals are edible. I saved a bunch to add to teas. Just carefully remove the soft white and pink petals without removing the whole flower.
Feijoa pairs well with: Ginger,Coconut, Apple, Cinnamon, Chilli, Citrus, Pear, Nuts, Dark chocolate, Yogurt
Feijoa ideas:
Juices
Smoothies
Cakes
Jam
Crumble
Muffins
Icecream
Preserving your Feijoa Harvest
Feijoa trees, once mature, will produce bucketloads of fruit! They can be frozen to use in smoothies and juices or baking, or preserved in jams, chutney, alcohol infusions, and bottled.
Edible flowers offer so many beneficial relationships within a home garden. When creating a sustainable permaculture garden, everything should have multiple functions and uses. The more the better! Edible flowers not only look beautiful, but they also aid in pollination, provide food and habitat to beneficial insects for pest management, add diversity to the soil and provide food, and in some cases, offer medicinal qualities for us.
Without adequate pollination, crops may be smaller, less abundant or may not produce at all. So, it is important that we attract pollinators to our gardens to increase yields along with the quality of produce.
Note: not all flowers are edible. Make sure you identify them correctly. Do not eat flowers from florists or areas unknown, as they may have been sprayed with pesticides. The safest option is to grow your own.
Pick your edible flowers in the morning but after the sun has come up. First thing in the morning the flowers will still be closed, so wait until they fully open up. They will be at their best in the morning, full of life and well-hydrated. If you are serving them fresh, pick your edible flowers as close to serving time as possible. Otherwise, place stems in a jar of water or keep in a moistened towel somewhere cool.
