Blueberries are a delicious and nutritious fruit that can thrive in Florida’s unique climate. Whether you’re a seasoned gardener or just starting out, growing blueberries can be a rewarding experience. In this guide, we’ll explore the best practices for growing and fertilizing blueberries in the Sunshine State.
Growing Blueberries in Florida
Florida’s warm climate and acidic soil make it an ideal location for growing certain varieties of blueberries. With proper care and attention, you can enjoy a bountiful harvest of these sweet berries right from your own backyard.
When to Plant Blueberries in Florida
The timing of planting is crucial for the success of your blueberry bushes. In Florida, the best time to plant blueberries is between mid-December and mid-February. This period allows the plants to establish their root systems before the heat of summer arrives. Planting during this cooler time of year gives your blueberry bushes the best chance to thrive and produce a good yield in the coming seasons.
Where to Grow Florida Blueberries
Choosing the right location for your blueberry plants is essential for their growth and productivity. Let’s explore some options for growing blueberries in Florida.
Growing Blueberries in the Ground
At Council-Oxford, we recommend planting blueberries directly in the ground. This method allows the plants to develop a strong, extensive root system and reduces the risk of root burn. When planting in the ground:
1. Choose a location with well-draining soil and plenty of sunlight.
2. Ensure the soil pH is between 4.5 and 5.5, which is ideal for blueberries.
3. Amend the soil with organic matter such as peat moss or pine bark to improve drainage and acidity. Pine bark either 2 or 3 inches deep and will help control soil temperatures and weed control.
4. Space plants about 4-5 feet apart to allow for proper air circulation and growth.
Growing Blueberries in Florida in Pots
If you have limited space or want more control over the growing conditions, you can grow blueberries in pots. When using containers:
1. Select a large pot (at least 18 inches in diameter) with drainage holes.
2. Use a potting mix specifically designed for acid-loving plants or create your own by mixing equal parts peat moss, pine bark, and perlite.
3. Place the pots in an area that receives at least 6 hours of direct sunlight daily.
4. Water more frequently, as potted plants tend to dry out faster than those in the ground.
Other Spaces for Blueberries to Thrive
Blueberries can also be grown in various other spaces, including:
1. Raised beds: Ideal for areas with poor soil drainage or to create a dedicated blueberry patch.
2. Along fences: Utilize vertical space and create an edible border in your yard.
3. As part of an edible landscape: Integrate blueberry bushes into your existing garden design for both beauty and function.
By choosing the right location and method for growing your blueberries, you’ll be well on your way to enjoying fresh, homegrown berries in Florida.
Caring for a Blueberry Bush
Proper care is essential for healthy blueberry bushes and a bountiful harvest. Here are some key aspects to consider when caring for your blueberry plants in Florida.
Prepare the Site First
Before planting your blueberries, it’s crucial to prepare the site properly:
1. Complete a soil test: Blueberries thrive in acidic soil with a pH between 4.0 and 5.5. If your soil is not within this range, it will not effectively support blueberry growth. You can obtain a soil test kit from your local extension office or garden center.
2. Adjust soil pH: If your soil pH is too high, you can lower it by adding elemental sulfur, aluminum sulfate, or organic matter like pine needles or peat moss.
3. Improve drainage: Ensure the planting site has good drainage to prevent root rot. If necessary, create raised beds or mounds to improve soil drainage.
Monitor for Fungus and Insect Pressure
Blueberries can be susceptible to various fungal diseases and insect pests. Regular monitoring is essential to catch and address any issues early:
1. Watch for signs of fungal diseases such as leaf spot, stem blight, or root rot. These often appear as discolored leaves, wilting, or stunted growth. Treat with proper fungicide to stop any issues.
2. Keep an eye out for common insect pests like blueberry gall midge, thrips, and scales. Look for distorted leaves, small insects on the undersides of leaves, or sticky residue on the plant.
3. Implement integrated pest management practices, using organic or chemical controls as needed, based on the severity of the issue.
When to Fertilize Florida Blueberries
Proper fertilization is key to healthy blueberry plants and optimal fruit production. In Florida, the general fertilization schedule for blueberries is as follows:
1. New plants: Begin fertilizing 3-4 weeks after planting, once the plant shows signs of new growth.
2. Established plants: Apply fertilizer three times a year – in early spring (February-March), early summer (May-June), and late summer (August-September).
3. Avoid fertilizing in late fall or winter, as this can stimulate new growth that may be damaged by cold temperatures.
What is the Best Fertilizer for Blueberries?
Blueberries have specific nutritional needs that differ from many other plants. They prefer a fertilizer with a lower nitrogen content relative to phosphorus and potassium. At Council Oxford, we carry a blueberry-specific fertilizer with a 6-8-8 ratio, which is ideal for blueberry plants.
This specialized fertilizer provides:
– Lower nitrogen (6%) to prevent excessive leaf growth at the expense of fruit production
– Higher phosphorus (8%) to promote strong root development and flower formation
– Higher potassium (8%) to enhance overall plant health and fruit quality

How Often Do Blueberries Need Watered in Florida?
Proper irrigation is crucial for blueberry plants, especially in Florida’s warm climate. The water needs of blueberries vary throughout the growing season:
1. March: Mature blueberry plants require about 0.6 inches of water per week (rainfall plus irrigation).
2. Late spring and summer: As leaf canopies develop and temperatures increase, plants need 1.0–1.2 inches of water per week (rainfall plus irrigation).
3. The frequency of irrigation depends on several factors:
– Weather conditions
– Soil type
– Type of blueberry (rabbiteye or southern highbush)
4. Established rabbiteye blueberries in gardens typically require irrigation only during prolonged dry periods.
5. Use mulch around the base of the plants to help retain soil moisture and reduce watering frequency.
Remember to monitor your plants closely and adjust watering as needed based on rainfall and plant appearance. Overwatering can be just as harmful as underwatering, so aim for consistently moist but not waterlogged soil.
By following these guidelines for care, fertilization, and watering, you’ll be well on your way to growing healthy, productive blueberry plants in Florida. Don’t hesitate to reach out to us at Council-Oxford for any additional advice or products you may need for your blueberry-growing journey!
