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

Benefits of Growing Pigeon Pea in a Permaculture Garden
1. Pigeon Pea Improves Soil Health
Pigeon pea is an excellent nitrogen fixer, meaning it naturally enriches the soil by pulling nitrogen from the air and making it available to other plants. This is especially valuable in poor, sandy soils where organic matter is often lacking. Additionally, its deep taproot helps break up compacted soil, improving aeration and water retention. It is a great plant to grow in newly established gardens where soil quality is low.
2. Creates Dappled Shade
This shrub grows quickly and provides light, dappled shade that protects lower-growing plants from harsh sun exposure. This makes it an excellent companion plant for young fruit trees and vegetable crops that benefit from reduced heat stress.
3. Attracts Beneficial Insects & Pollinators
The bright yellow flowers of pigeon pea are highly attractive to bees, butterflies, and other beneficial insects. These pollinators help increase biodiversity in your garden and improve the yield of surrounding fruiting plants.
4. Nutritious & Versatile Edible Crop
Pigeon peas are a rich source of protein, carbohydrates, and fiber, making them a valuable addition to a self-sufficient diet. They can be eaten in various ways:
Fresh in salads
Steamed like edamame
Cooked in stews and curries
Made into burger patties
Dried and stored for long-term use
Not only are pigeon peas beneficial for human consumption, but they also make excellent high-protein animal feed.
5. Provides Abundant Biomass & Mulch
Pigeon pea produces a significant amount of organic material that can be cut back and used as mulch. This helps retain soil moisture, suppress weeds, and build healthy soil over time. Regular pruning encourages new growth and keeps the plant productive.
6. Windbreak & Habitat for Wildlife
This shrub can be grown as a hedge to provide wind protection for more delicate plants. It also creates shelter for small birds and insects, enhancing the overall ecosystem of your garden.
7. Pioneer Plant for New Gardens
Pigeon pea is an ideal “pioneer” species for establishing new gardens. This means it helps pave the way for establishing more valuable long-term crops. It offers:
Fast-growing shade
Nutrient-rich mulch
Green material for composting
Pollinator attraction
Wind protection
Thrives in poor soil
Drought tolerant
It is a short-lived perennial, typically lasting 4-5 years, making it perfect for supporting other plants in the early stages of a food forest or permaculture system. As your garden grows and your main fruit tree crops start to get established you can prune back and remove the Pigeon Pea to make room. With so much seed available you will be able to re-grow more plants in other areas of the garden.
How to Grow Pigeon Pea
Pigeon PeaPlanting & Soil Requirements

Edible Climbing Vines help maximise growing space and double the amount of food in each garden bed or container. One thing that I think is so underrated is the ability to grow food up 👆
Today I am going to share a list of edible climbers to grow in your garden and utilise vertical space and create shade and protection. These 10 edible climbing vines are perennials which means they will produce more and more food each year without us having to replant them!
There are so many incredible reasons you should be growing food vertically.
Not only to maximize space but also to increase airflow to reduce rot or disease, strategic shade, or like me to reduce some of the heat in my garden by covering my ugly fences!

Annuals vs Perennials 🌿
Annuals will allow you to still change up your garden beds each season and have the flexibility of space. Whereas perennials (which grow for longer than 2 years) will allow you to get a crop established and provide long-term protection and produce more and more food each year.
10 Perennial Edible Climbing Vines
1. Passionfruit
Passionfruit is one of my favourite fruits to eat and the main reason I am growing this edible climber in my garden. They are also evergreen so it has leaves all year round to create shade and protection. Passionfruit have thick, lush leaves so they work perfectly to cover fences or create screens to block out unsightly structures or areas.
Watch the video above to see how to plant passionfruit from a store-bought fruit!
BONUS TIP: Purchase a passionfruit plant that is NOT grafted. Grafted passionfruit needs to be carefully maintained or the rootstock can quickly take over and become invasive with no fruit.
2. Choko /Chayote
Choko is a quick-growing vining edible plant that can make great summer shade to protect your summer garden. They will often die back over winter but will pop up and regrow each spring. Any fruits left on the ground will also easily regrow.
Choko are similar to a large zucchini or marrow and can be used as a substitute for potatoes or even apples to bulk up pie recipes.
3. Sweet Potato
Growing Sweet Potatoes / Kūmara (Ipomoea batatas) in your home garden is a great step toward self-sufficiency. They are my favourite permaculture plant and are an easy crop to grow for beginner gardeners. It is important to grow plants that support and encourage other plants and beneficial insects in your garden. Creating a cohesive ecosystem that promotes the growth and success of your garden’s health and supports abundant harvests.
Sweet potatoes send out runners and can easily be trained up a vertical trellis. Plus, many people do not know that the leaves of the sweet potato plant are also edible.
4. Grapes
The great thing about growing grapes as edible climbers is that they are deciduous. This means they lose their leaves in winter so you can plant grapes strategically to provide shade in summer and let light through in winter!
5. Malabar Spinach
Malabar spinach is a fantastic edible climber for warm or tropical climates. It thrives in summer during warm weather when most other spinach and leafy greens die off. This can help fill the gaps in your seasonal harvests. Malabar spinach can be grown in pots or containers. It has succulent-like leaves so can handle hot weather but it can be frost sensitive.
6. Butterfly Pea
If you love colour then this edible climber will be perfect for you! With bright blue-purple flowers the butterfly pea is a striking addition to an edible garden. The flowers can be used as a natural food colouring or infused in teas or cocktails. Plus, if you add acidity such as lemon juice the colour will transform to hot pink! Such a fun plant to grow.
7. Kiwifruit
Kiwifruit can be grown over structures to create great canopy shade. They are prolific produces and the fruit can be eaten fresh, frozen for smoothies, made into jams and even dehydrated for naturally sweet treats. You will need to have both a male and a female plant for pollination.
8. Kiwiberry
Kiwi berries have a similar taste to the kiwifruit but are much smaller around the same size as a grape. Kiwi berry vines grow really well in containers or urban gardens.
9. Nasturtium
Nasturtium is often known for its wild rambling nature but it can be trained vertically as an edible climber. The whole plant is edible including the leaves, flowers and seed pods. Nasturtium has a strong peppery taste and can be used in salads, flavoured salts, pickles and many other recipes. Here in Perth, my Nasturtium dies down in summer but will pop up and regrow by itself in Autumn/winter.
10. Scarlett Runner Bean
Scarlet runner beans are also known as the 7-year bean because they pop up and regrow each year (for about 6-7 years). Beans are a great addition to an edible garden and can easily be cooked or frozen to preserve.
Annual Climbing Vines 🌿
Annual climbers are also great because they don’t need dedicated space so you can grow, harvest and remove then grow something different each season! Having a mix of annuals and perennials will help you grow more food all year round.
Annual climbers can be plants such as Cucumber, Squash, Tomatoes, Pumpkin, and Melons.
Lemon Balm (Melissa officinalis) is a perennial herb with fragrant lemon-scented leaves. Lemon balm is part of the Mint family and is known for having weed life growth and self-seeds easily. With hundreds of small white flowers, the lemon balm is a powerful bee attractant. It has toothed edges and slightly hairy leaves with a lemony scent.
Lemon balm-like many herbs has been traditionally used to aid in an array of health conditions. With calming and relaxing properties as well as anti-viral and anti-bacterial qualities, lemon balm is a great addition to a kitchen garden.

When to Plant Lemon Balm
Lemon balm grows well most of the year. new plants should be planted after the last frost. If planting in summer keep well watered.
How to Grow Lemon Balm
Choose a sunny spot with dappled or part shade in the heat of summer.
Prepare the soil with rich compost
Direct sow seeds or plant in seed trays first.
1 plant is plenty.
Can benefit from protection during the heat of summer.
Care/ Maintenance
Lemon balm like Mint is a thirsty plant. Keep well watered and have a drip tray for pots. Cut back the plant after it has finished flowering to promote new growth.
Once the plant is well-established harvest sprigs as needed.
Use clean, sharp kitchen scissors to cut your harvest, or just pick with your hands to prevent the spreading of diseases.
Cut and come again crop that will regrow quickly. I often harvest and use in cold drinks or teas every other day.
Reproducing
Take cuttings and allow to root in a jar of water. Refresh the water every few days. Seeds can also be saved and will flower with white flowers on the stem. Once the seeds form and turn brown, collect them and dry them further. Keep in a dark, cool and dry environment.
Cooking and Using Lemon Balm
Lemon balm is best used fresh. Dried leaves lose their scent and flavour.
