When to Plant Redbor Kale in Maryland
The ideal time to plant Redbor Kale in Maryland depends on the specific zone you reside in. Keep in mind that these are general guidelines, and slight variations may occur due to microclimates or seasonal fluctuations.
Redbor Kale, with its stunning dark purple leaves, is a versatile and nutritious addition to any garden. Not only does it provide a pop of color, but it is also packed with vitamins and antioxidants, making it a valuable addition to your diet.

Remember to consult local gardening resources, such as your county’s agricultural extension office or trusted nurseries, for more precise planting dates in your area.
When planting Redbor Kale, ensure that the soil is well-draining and rich in organic matter. This will provide your kale plants with the nutrients they need to flourish. Additionally, consider companion planting with herbs like dill or cilantro to naturally repel pests and attract beneficial insects to your garden.
How to Grow Redbor Kale in Maryland
Now that you know when to plant Redbor Kale let’s delve into the steps needed to grow these vibrant greens successfully.
1. Choose the Right Location
Selecting the perfect spot for your Redbor Kale is crucial to ensure its healthy growth. Look for a garden bed or container that receives at least six hours of direct sunlight daily. This will provide the kale with the necessary energy to thrive. Additionally, make sure the soil is well-draining and rich in organic matter. Redbor Kale prefers a slightly acidic pH between 6.0 and 6.5, so keep that in mind when selecting your location.
2. Prepare the Soil
Preparing the soil is an essential step in setting the foundation for your Redbor Kale’s growth. Start by amending the soil with compost or well-rotted manure to boost nutrient levels. This will provide the kale with the necessary nourishment it needs to flourish. Work the amendment into the top 6-8 inches of soil, removing any rocks or debris in the process. By creating a nutrient-rich environment, you are ensuring the best possible conditions for your Redbor Kale to thrive.
3. Sow Redbor Kale Seeds
Now it’s time to sow the Redbor Kale seeds and watch your garden come to life. Plant the seeds in rows about 12-18 inches apart, giving them enough space to grow and spread their vibrant leaves. Sow the seeds directly into the soil, approximately a quarter to a half-inch deep. If you prefer seedlings, you can start them indoors 4-6 weeks before the last expected frost date and later transplant them outdoors. This will give your kale a head start and ensure a bountiful harvest.
Note: If you choose to start with seedlings, make sure to harden them off gradually by exposing them to outdoor conditions over a period of time. This will help them adjust to the change and prevent transplant shock.
4. Water Regularly
Proper watering is key to the success of your Redbor Kale. While it requires consistent moisture, it’s important to avoid over-watering, as this can lead to root rot and other issues. Aim to keep the soil evenly moist, providing approximately 1-1.5 inches of water per week. Consider using a drip irrigation system for more precise watering, ensuring that the kale receives the right amount of moisture without wasting water. Remember, a well-hydrated kale plant is a happy and healthy one!
5. Fertilize Adequately
As a heavy feeder, Redbor Kale needs an adequate supply of nutrients to thrive. To ensure your kale receives the nourishment it requires, apply a balanced fertilizer according to the package instructions. Alternatively, you can opt for organic alternatives such as compost tea or fish emulsion. These natural fertilizers not only provide essential nutrients but also improve the overall soil health. By feeding your Redbor Kale properly, you are setting the stage for a vibrant and productive harvest.
6. Control Pests and Diseases
Protecting your Redbor Kale from pests and diseases is crucial to maintain its health and productivity. Regularly monitor your plants for common pests like aphids, cabbage worms, or flea beetles. If you spot any of these unwanted visitors, don’t panic! There are organic pest control methods you can employ to deter them. Consider using neem oil or insecticidal soap, which are effective and environmentally friendly options. Additionally, practicing crop rotation and maintaining good airflow around your plants can help prevent diseases like powdery mildew or clubroot. By taking these preventive measures, you are ensuring that your Redbor Kale remains strong and resilient throughout its growth cycle.
When to Harvest or Pick Redbor Kale in Maryland
One of the most rewarding moments is harvesting your homegrown Redbor Kale when the leaves are at their peak. Harvesting time depends on your preferences and weather conditions.
Typically, you can start harvesting Redbor Kale leaves when they reach about 8-10 inches in length. Regularly pick the outer leaves from the bottom of the plant, allowing the inner ones to continue growing.
During the cooler months, Redbor Kale leaves tend to develop a sweeter taste due to frost-kissed sugars. Many gardeners even claim that this variety becomes tastier after a light frost.
