Pruning and Training Techniques for Kiwi Plants

Proper pruning and training are crucial for maintaining the health and productivity of your kiwi fruit plants. By implementing the right techniques, such as espalier and pergola training, you can effectively control the size and shape of your plants while encouraging vigorous growth and fruiting.

Espalier Training:

Espalier training involves training your kiwi plants to grow along a flat surface, such as a wall or fence, using a series of horizontal wires. This technique not only saves space but also makes it easier to manage and harvest the fruit. Begin by selecting a main stem and gently tying it to the lowermost wire, ensuring that it is evenly spaced. As lateral shoots develop, train them horizontally along the wires, pruning any excess growth. This method promotes better sunlight exposure and airflow, leading to improved fruit quality.

Pergola Training:

If you have more space available, pergola training is another excellent option for kiwi plants. This training method involves allowing the vines to grow vertically, creating a shaded area beneath the canopy. Install sturdy supports such as wooden posts or metal structures, and then guide the vines upwards using twine or clips. Regularly prune the lateral shoots to maintain the desired shape and prevent overcrowding. The pergola training method not only provides a beautiful garden feature but also allows for easier access to the fruit and improved air circulation.

Training Technique Pros Cons
Espalier – Saves space – Requires regular pruning
Pergola – Provides a shaded area – Requires more space

Pruning and Training Techniques for Kiwi Plants

  • In winter, prune your kiwi plants by removing any dead, damaged, or weak branches. This allows for better airflow and reduces the risk of disease.
  • During summer, focus on pruning back lateral shoots that have started to form fruit. This helps divert energy towards the remaining fruit, leading to larger and sweeter harvests.

“Proper pruning and training techniques are essential for maintaining the health and productivity of your kiwi plants. By implementing methods such as espalier and pergola training, you can optimize space, ensure even fruiting, and create a beautiful garden feature.”

Harvesting Your Kiwi Fruits

After years of nurturing your kiwi plants, the much-anticipated harvest time has arrived. Harvesting kiwi fruits can be a rewarding experience, but it’s important to know when and how to pick them to ensure optimal flavor and ripeness. In the UK, where summers may not be long and hot enough for kiwis to fully ripen outdoors, it is best to pick the fruits in the autumn and allow them to ripen indoors.

To determine whether your kiwi fruits are ready for harvesting, gently press the fruit with your thumb. Ripe kiwis will yield slightly to gentle pressure. Avoid picking them when they are still firm as they may not ripen properly. If you find any unripe fruit remaining on the plant before the first hard frost, it’s best to pick them and store them indoors for ripening.

Once harvested, kiwi fruits can be stored in a cool and well-ventilated place for several months. Keep them away from other fruits, as they release ethylene gas which can cause premature ripening. To speed up the ripening process of picked kiwis, place them in a paper bag with a ripe banana or apple, as these fruits produce ethylene gas that helps accelerate the ripening of other fruits.

Remember, the flavor of kiwi fruits can intensify as they continue to ripen, so it’s important to taste them regularly to ensure they are at the desired sweetness before consumption. Enjoy the fruits of your labor!
