How to Grow an Avocado Plant from a Stone

Choosing the Right Avocado Stone

Growing an avocado plant from a stone starts with choosing a ripe and healthy avocado. Once the fruit is eaten and the stone removed, rinse it gently to remove any remaining flesh. It’s important not to use soap or scrub too hard as the outer layer of the stone helps protect the seed inside.

Preparing the Stone for Sprouting

After cleaning, determine which end is the top and which is the bottom. The slightly pointier end is the top and the flatter base is where roots will grow. Insert three or four cocktail sticks into the stone around its midsection at a slight angle. These sticks will act as a support, allowing the base of the stone to rest in water while keeping the top exposed to air.

Rooting the Avocado Stone in Water

Place the suspended stone over a glass of water with the base just submerged. Set the glass in a warm and bright area out of direct sunlight. Refresh the water every few days to prevent mould or stagnation. In two to six weeks, the stone should begin to split and sprout roots from the base followed by a small shoot from the top.

Transferring the Seedling to Soil

Once the roots are well-developed and the shoot is about 15 centimetres tall, it is time to plant the stone in compost-rich soil. Use a pot with drainage holes and bury the lower half of the stone while leaving the upper half exposed. Water it thoroughly and place the pot in a sunny spot where the temperature remains consistent.

Encouraging Healthy Growth Indoors

To keep your avocado plant thriving, water it regularly but avoid soggy soil. If the plant becomes leggy, pinch out the top leaves to encourage bushier growth. During the cooler months, reduce watering slightly and make sure the plant is protected from cold draughts. With the right care, your avocado plant can become a beautiful indoor feature.

Caring for Your Avocado Plant as it Grows

As your avocado plant begins to establish itself in the soil, it’s important to pay attention to its overall health. Avocados prefer bright indirect light, so placing the pot near a window that receives plenty of daylight without harsh sun is ideal. If the leaves begin to curl or discolour, it may be a sign of too much sun or insufficient water. Gently wiping the leaves with a damp cloth can help keep them free of dust and improve their ability to photosynthesise.

Repotting for Continued Growth

Over time, the avocado plant will outgrow its original pot. When you notice roots pushing out from the drainage holes or if growth appears stunted, it’s a good time to repot. Choose a slightly larger pot and refresh the compost with a well-draining mix. Carefully remove the plant, taking care not to damage the roots, and replant it at the same depth. This will give the roots more space to expand and support the upper growth.

Pruning and Shaping the Plant

Avocado plants tend to grow tall and slender, especially when grown indoors. Pruning is a great way to encourage side shoots and create a fuller shape. When the stem reaches around 30 centimetres tall, trimming the top few centimetres can help promote branching. Repeat the process as the plant grows, always cutting just above a leaf node. This helps the plant stay compact and attractive rather than spindly.

Dealing with Common Issues

Indoor avocado plants are generally low maintenance but they can sometimes attract pests such as spider mites or aphids. A simple solution of mild soapy water sprayed on the leaves can help deter these. Overwatering is another common issue, often signalled by yellowing leaves or soft stems. Always check the top layer of soil before watering again and ensure excess water is allowed to drain away freely.

Will It Ever Bear Fruit?

One of the most common questions is whether a homegrown avocado plant will produce fruit. While it is possible, it is not guaranteed. Most avocado trees grown from stone will not bear fruit for several years, and even then only under specific conditions such as consistent warmth, ample light and even hand-pollination in the absence of outdoor pollinators. However, many people enjoy growing avocados purely as ornamental plants, appreciating the process and the lush green foliage without the pressure of a harvest.
