How long does kale typically grow in the garden before harvesting?
Kale can usually be harvested about 55 to 75 days after planting, depending on the variety and growing conditions. The leaves can be picked once they reach a desirable size, typically when they are about 6 to 8 inches long. Early harvesting encourages more growth, as the plant will continue to produce new leaves if it’s cut back frequently.
Keep in mind that kale can be grown as either a spring or fall crop. When planted in the cooler months, kale might take longer to mature due to slower growth rates. Nonetheless, the cooler temperatures can actually enhance the flavor of the leaves, making them sweeter and more desirable for consumption.
Can kale survive through the winter months?
Yes, kale is quite hardy and can survive through winter, especially if it is grown in milder climates. It’s known for its impressive frost tolerance, as exposure to cold temperatures can improve the flavor of the leaves. Many gardeners appreciate kale for this property, as it allows them to have fresh greens available even in winter.
However, in areas where winter temperatures drop significantly, gardeners may need to provide some protection, such as using row covers or poly tunnels. This will help to ensure that the plants survive the harshest conditions and continue to thrive throughout the season.
How often should kale be watered for optimal growth?
Kale requires consistent moisture for optimal growth and flavor. It is essential to keep the soil evenly moist, especially during dry spells. Typically, watering the plants about once a week is sufficient, but you may need to adjust this frequency depending on the rainfall and temperature in your area.
Overwatering should be avoided, as it can lead to root rot and other diseases. Checking the soil moisture by pressing it with your finger can help determine if it’s time to water. A good rule of thumb is that the top inch of soil should be dry before you water again.
