Knowing whether to support your plants with garden stakes or let them sprawl freely is a concern of experienced gardeners and new green thumbs alike. Getting this decision right can mean the difference between a thriving garden and struggling plants that fail to reach their potential.
Here is some practical advice for common plants on when to use garden stakes and what type to use. Understanding the specific needs of each plant will help you make better choices for your garden's success.
Garden stakes serve multiple purposes beyond simply keeping plants upright. They protect developing fruit from soil-borne diseases, improve air circulation around foliage, and make harvesting considerably easier.
Proper staking also trains plants to grow in a more compact and manageable form. This is particularly important in suburban Australian gardens where space is often limited and every square metre counts.
However, not all plants benefit from staking, and incorrect staking can actually harm plant development. The key is knowing which plants need support, when to provide it, and importantly, when to remove it.
Staking your tomato plant will keep the fruit off the ground, make it easier to harvest and help the plant to avoid disease. Many common fungal problems develop when tomatoes rest on damp soil, so elevation is crucial for healthy crops.
You will need to stake a tomato plant when it is newly planted. It is best to choose a long stake, around 180-240 cm to accommodate the full height of indeterminate varieties.
The stake you choose will be with the plant for its lifetime, as you will need to tie the new growth to the stake as it grows. For tomatoes and other tall vegetables, these 1800mm hardwood stakes provide the height needed without bending or breaking under the weight of mature plants laden with fruit.
Other vegetables that benefit from staking include:
The good old lemon tree is a feature of many Aussie backyards. When planting a young lemon tree, garden stakes will help the early development as young trees have a root-ball that needs to grow into stabilised roots.
Staking during the first growing season will give the tree the support it needs to grow strong roots. This is especially important in areas with strong winds or when planting bare-rooted specimens that haven't established their anchor roots yet.
Don't leave stakes in too long as it can cause the root system to become underdeveloped. Wind and the sway of the tree cause the trunk to thicken and develop the strength needed to stand independently.
Ensure you do not tie the tree higher than halfway or too tightly, as it will impact growth. The tree should be able to move slightly in the breeze while being prevented from toppling over completely.
For standard fruit trees and native specimens, these 1500mm hardwood stakes offer sufficient height for most young trees while remaining economical for planting multiple specimens.
Key considerations when staking young trees:
Wind and competition from other plants in the natural environment encourage plants to grow quickly and develop strong roots. However, indoor plants are protected from the elements and can grow weak stems so garden stakes can help prevent flopping and breakage.
Common indoor plants like Philodendron and Monstera can benefit from the aid of stakes. These climbing species naturally grow up tree trunks in their native habitats and appreciate vertical support in your home.
All you need is a simple thin and straight stake and flexible ties to loosely stake the plant. Bamboo stakes work well for lighter indoor plants, while heavier specimens may require more substantial support.
Container plants on balconies and patios face unique challenges. They're more exposed to wind than indoor plants but lack the root space that ground-planted specimens enjoy.
Potted plants that commonly need staking:
Different materials suit different applications, and understanding the pros and cons helps you choose wisely. Cost, longevity, appearance and environmental impact all play a role in the decision.
Here's how common stake materials compare:
| Material | Lifespan | Best Use | Considerations |
|---|---|---|---|
| Hardwood | 3-5 years | Trees, vegetables | Durable, natural look, weather-resistant |
| Bamboo | 1-2 years | Indoor plants, annuals | Lightweight, renewable, degrades outdoors |
| Plastic/Fibreglass | 10+ years | Long-term applications | Very durable but less natural appearance |
| Metal | 10+ years | Heavy plants, permanent structures | Strong but can rust or heat up in sun |
| Treated pine | 5-7 years | General purpose | Affordable but treatment chemicals may concern some gardeners |
Hardwood stakes offer an excellent balance of durability and natural aesthetics. They're strong enough for most applications yet break down eventually without leaving permanent waste in your garden.
Stakes work best as part of a complete plant care system. Protecting the area around staked plants prevents weed competition and moisture loss that can stress supported specimens.
Young trees particularly benefit from weed suppression around their base. These 600mm jute mats are perfectly sized for individual tree plantings and break down naturally after the critical establishment period.
For newly planted trees and shrubs, protection from wildlife and weather damage is equally important as staking. The Green-POD large tree guard shields young plants from browsing animals and harsh winds while allowing light and moisture through.
In larger planting projects like revegetation or orchard establishment, controlling weeds between rows saves countless hours of maintenance. Professional-grade weed matting reduces competition and helps staked plants establish faster with less irrigation.
Even experienced gardeners sometimes get staking wrong. The most common error is leaving stakes in place too long, which prevents natural trunk and stem strengthening.
Tying plants too tightly is another frequent problem. Ties should allow some movement and must be checked regularly as stems expand.
Other mistakes that compromise plant health:
These common plants benefit from garden stakes, as do many other varieties throughout Australian gardens. Keep the simple idea in mind that most trees only need a helping hand and stakes should be temporary.
Other plants will grow up a stake throughout their lifetime, so choose the material wisely based on how long support will be needed. Matching the right stake to each plant's specific requirements ensures healthy growth and a productive garden.
