Have you ever heard of the Australian finger lime tree, also known as the "citrus caviar"? This tree is native to Australia and is known for its unique fruits. The fruits are long and have small, bead-like juice vesicles that look like caviar. When these burst, they release a tangy and flavorful citrus taste.
This makes the fruit a popular choice for culinary uses, garnishes, and cocktails. But how do you care for an Australian finger lime tree in a container? It's important to know the right growing conditions to keep the tree healthy and ensure it produces lots of fruit.
What is the Australian Finger Lime Tree?
The Australian finger lime, known scientifically as Microcitrus australasica or Citrus australasica, is a special citrus tree from Australia's rainforests. It's not like common citrus fruits like lemons or oranges. This tree is unique because of its special features.
This tree can grow 6-25 feet tall and is an evergreen shrub or small tree. Its leaves are small and have thorns at the base. The flowers are bright pink and change to pale pink or white as they age. The fruit looks like long, curved fingers, which is why it's called a finger lime.
The Australian finger lime is mostly seedless or has a few small seeds. Inside the fruit, there's a special pulp that tastes tangy and refreshing. This makes it a favorite in many recipes, from drinks to seafood dishes.

Growing Conditions for the Lemonade Tree
The Australian finger lime tree, also known as the "lemonade tree," is perfect for warm, sunny areas. It can grow in many climates and settings. But, it needs protection from frost because it can't handle cold.
Lemonade trees do well in containers, making them great for small spaces or cooler climates. You can move them indoors during winter. They start producing fruit in 1-2 years and reach full production in 4-5 years.
Lemonade trees bloom in the fall and are ready to eat from March to May. The exact timing can vary based on your area's climate.
- Lemonade trees love full sun, needing 6-8 hours of sunlight daily.
- They prefer soil with a pH of 5.5 to 6.5, which is slightly acidic to neutral.
- These trees do best in well-draining soils and need good air circulation.
- It's important to water them regularly, deeply during dry spells, and avoid waterlogging.
Knowing how to care for lemonade trees helps gardeners grow these tasty citrus plants. They can add a unique flavor to any garden or container.
Planting and Container Considerations
Planting the Australian finger lime tree, also known as the lemonade tree, needs careful timing and location. Spring after the last frost is the best time to plant a young tree. You can also plant in summer, but avoid high temperatures over 90°F for a few weeks to help the tree adjust.
Find a spot that gets plenty of sun and has good drainage for planting the lemonade tree. This tree has many thorns, so pick a place where people or pets won't bump into it often. Also, make sure it's protected from strong winds, as they can harm the fruit.
You can plant the lemonade tree in a big container or directly in the ground. If using a container, go for a 10-gallon pot and a citrus plant potting mix. The Air Pot is a great choice for containers, as it helps with root growth and keeps the soil well-drained.
Whether you plant the lemonade tree in the ground or a container, make sure it gets the right conditions. With proper care, you'll enjoy the unique taste of finger limes from this citrus tree for many years.
Caring for Your Lemonade Tree
To keep your Australian finger lime, or "lemonade tree," healthy, you need to give it the right care. These trees love sunlight, needing at least 6 hours of direct sun each day. They can grow in USDA zones 8-11 but can also be grown in colder areas if kept indoors during the cold months.
For the best growth, keep the temperature warm. Aim for summer temperatures above 90°F and winters above 40°F. Make sure to protect the tree from freezing, as it's sensitive to frost.
Watering your lemonade tree regularly is crucial for its health. Water it in the morning, once or twice a week, to keep the soil moist but not too wet. If your tree is in a pot, you might need to water it more often since the soil dries out quicker. Feed your tree in spring and summer with a citrus fertilizer or a 12-6-6 blend to help it grow well.
Pruning your lemonade tree is key to keeping it the right size and healthy. Remove any dead shoots and branches to keep it looking good. Be careful, though, as the tree has thorns. Regular pruning will help your tree stay healthy and under control.
Pest and Disease Management
Keeping your lemonade tree healthy is key for lots of fruit. Watch out for pests like aphids, mealybugs, and scale insects. Check leaves and stems often for pests. Use organic or chemical treatments like Captain Jack's Insecticidal Super Soap or Mite X if you find pests.
The Australian finger lime is tough against Huanglongbing (HLB), also known as citrus greening. This disease can make fruit small and deformed and can kill the tree. Knowing this can help protect your citrus trees and keep them healthy for a long time.
| Pest or Disease | Symptoms | Management Strategies |
|---|---|---|
| Citrus Scab | Raised, pink or brown scabs that progress to dark gray and crack; spores spread by rain splashing | Maintain proper tree health and hygiene, including pruning and removing fallen fruit |
| Citrus Variegated Chlorosis (CVC) | Yellowing of leaves, resembling zinc deficiency, and brown lesions on leaf undersides | Use resistant rootstocks, ensure proper soil nutrition, and manage insect vectors |
| Citrus Black Spot | Black lesions on leaves and fruit, reducing quantity and quality | Apply fungicides at appropriate times, improve tree vigor, and remove fallen leaves |
| Citrus Greening (HLB) | Asymmetrical leaf blotches, falling leaves, fruit discoloration, premature branch death, and tree decline | Utilize the natural resistance of the finger lime tree, remove infected trees, and manage insect vectors |
By being vigilant and using the right control methods, you can keep your citrus orchard healthy. This will make sure you get lots of delicious and unique fruit.
Lemonade Tree Propagation Methods
Propagating the Australian finger lime, or lemonade tree, is rewarding for gardeners. Two main methods work well: grafting and rooted cuttings.
Grafting is a top choice for growing lemonade trees. The chip budding method is favored, where a bud from the desired tree is put into a rootstock seedling. This keeps the tree's unique traits while using the rootstock's strong growth.
Rooted cuttings are another easy way to grow lemonade trees. Take cuttings from new growth that hasn't yet had fruit or flowers. Add rooting hormone to help roots form faster. These trees do well in containers and shouldn't be planted in the ground.
- Grafting, especially chip budding, is a trusted way to grow lemonade trees
- Rooted cuttings are simple to use and great for containers
- Rooting hormone boosts the success of lemonade tree cuttings
Choosing grafting or rooted cuttings lets you grow your citrus collection affordably and with joy. With the right methods and care, you can enjoy the special tastes of this Australian fruit for many years.
Harvesting and Storing Lemonade Tree Fruit
Harvesting finger limes from your Lemonade tree requires care due to the thorny branches. To avoid injury, wear thick gloves and long sleeves. Gently twist and pluck the fruit without harming the tree.
The color of the "caviar limes" varies by type, from red to purple. Harvest them between March and May, when they're ripe and plump. This ensures they're ready to use.
- Wear protective gear like thick gloves and long sleeves to avoid thorns during harvesting.
- Gently twist and pluck the finger limes, being careful not to damage the tree.
- Harvest the lemonade fruit between March and May for best results.
- Look for plump, evenly colored finger limes as a sign of ripeness.
After picking, store the finger limes to keep them fresh. You can refrigerate them for up to two weeks or freeze for longer. Freezing works well if you put them in an airtight container or bag. Their unique taste and texture make them perfect for many dishes, from cocktails to desserts.
| Storage Method | Shelf Life |
|---|---|
| Refrigeration | Up to 2 weeks |
