When fertilizing your kiwi plants, remember a few things. First, it’s important to do a soil test to determine what nutrients your soil may be lacking. This will help you choose the right fertilizer for your plants.

Second, make sure to fertilize your kiwi plants at the right time. The best time to fertilize is in the winter, ideally before the end of February. This will give the plants enough time to absorb the nutrients before the growing season begins.

Third, be careful not to over-fertilize your kiwi plants. Too much fertilizer can actually harm the plants and reduce fruit production. Follow the manufacturer’s instructions and avoid applying too much.

Using organic fertilizers can be a great way to provide your plants with the nutrients they need while being environmentally friendly.

Finally, fertilizing is just one aspect of growing healthy and productive kiwi plants. Proper site selection, soil preparation, planting method, irrigation system, and training are also essential for developing a productive crop.

With these tips, you should be able to choose the best fertilizer for your kiwi plants, help them thrive, and enjoy a healthy and abundant harvest year after year. Happy gardening!
