Answer: Kiwis are deciduous plants so you should expect the leaves to turn brown and fall off in the winter months. (I suspect you already knew that, but I thought it was worth a mention.) If the new foliage is turning brown, it could be from over-fertilization (did you apply in amounts as recommended on the label?), or it could be a reaction to your alkaline soil. Kiwis are sensitive to salt burn in alkaline soils. You can have your soil tested, or you can dig your plants up, amend the soil with lots of organic matter (peat moss or compost with a little sulfur added), then replant. When you fertilize, use an acidified fertilizer (such as one formulated for camellias or rhododendrons to help neutralize the effects of alkaline soil). Best wishes with your kiwi plants!
