- A new raspberry plant may be undergoing transplant shock, which occurs when a plant is moved to a new growing environment. Many plants experience yellowing and even lose leaves shortly after transplanting. Most plants quickly recover from this shock. Providing the right amount of sunlight, the right type of soil and watering keeps the bush healthy. Creating ideal growing conditions encourages green leaves.
- Aphids and Japanese beetles are problems for raspberry plants. Both aphids and Japanese beetles feed on the leaves, draining them of important nutrients and weakening the plant. Aphids also spread disease, making them especially problematic. Applying pesticides, removing and destroying Japanese beetles by hand helps prevent them from damaging a new raspberry plant's leaves.
- The planting location of a raspberry bush is crucial to its health. Choose a location where the raspberry plant receives six to eight hours of sunlight. According to the Ohio State University Extension Fact Sheet, raspberries grow best in a sandy, loamy soil with a high organic content. Ensuring a healthy growing environment creates a healthy plant. Raspberries planted in poor growing locations produce weak, yellow leaves.
- Watering raspberry plants regularly keeps the leaves healthy and green. A lack of water dehydrates the raspberry plant, causing its leaves to become weak and discolored. Yellow or brown leaves can indicate dehydration, which also makes the plant more susceptible to pest and disease problems. Water the raspberry plant at least once a week. Avoid mulching the raspberry if the soil retains water, as this can encourage fungal growth, according to the Ohio State University Extension Fact Sheet.
