Choosing the Right Type of Turnip Seed

Choosing the right variety of turnip seeds is crucial for growing robust and flavorful microgreens. While several types of turnip seeds are available, 'Tokyo Turnip' and 'Just Right' are commonly recommended for microgreen cultivation due to their consistent germination rates and pleasant flavor profiles. Always opt for non-GMO seeds from reputable garden centers to ensure quality growth when purchasing seeds.

Understanding Soil Needs for Turnip Microgreens

Turnip microgreens thrive in a well-draining soil mix that is kept consistently moist. Compacted soils or those that drain slowly can lead to waterlogged conditions, increasing the risk of root rot diseases. Here are some key aspects of ideal soil for turnip microgreens:

• Texture: The soil should be light and fluffy to allow the delicate roots to penetrate easily.
• Nutrient Content: A rich potting mix with organic matter will provide turnip microgreens with the essential nutrients for healthy growth.
• pH Level: Turnip microgreens prefer slightly acidic soil with a pH level between 6.0 and 7.0. Adjusting your soil pH, if needed, can be done with the help of certain amendments available at garden centers.
• Moisture: While the soil should be kept moist, avoiding overwatering is crucial. A solid tray with drainage holes can help maintain the correct water level.

Ideal Temperatures and Light Conditions for Turnip Microgreens

Turnip microgreens are cool-weather crops that prefer temperatures between 15°C and 20°C for optimal growth. During the early growth stage, they require a blackout period of about 4-8 days. This simulates the conditions under the soil surface and encourages strong stem growth. After the blackout period, turnip microgreens need light for photosynthesis.

An ideal light source can be a sunny windowsill or an artificial grow light, providing at least 4-6 hours of light daily. These lights should be positioned close to the trays, 1-2 inches above the microgreens, to prevent the seedlings from becoming "leggy" or overly tall and thin.

The Planting Process

After preparing the right conditions for growing turnip microgreens, we can now delve into the planting process. This step-by-step guide will take you from sowing your turnip seeds to enjoying your homegrown microgreens.

Step-by-Step Guide to Germination

To achieve successful germination with turnip microgreens, follow these simple steps:

1. Preparation: Start by filling your chosen tray with your prepared soil mix. Spread the turnip seeds evenly over the soil's surface. Aim for a density that allows each seed to touch another seed.
2. Covering the Seeds: Lightly cover the seeds with a thin layer of additional soil. This mimics the natural germination conditions of turnip seeds and protects them from light, which can disrupt germination.
3. Moistening the Seeds: Using a spray bottle, moisten the soil thoroughly. The soil should be damp but not waterlogged.
4. Blackout Period: Place the tray in a dark, cool location for the blackout period, which lasts for about 4-8 days. During this time, ensure the soil stays moist but not soggy.
5. Germination: After the blackout period, move the tray to a location with indirect light and cooler temperatures. Soon, you'll see the first signs of germination - little white stems pushing up the soil.

Using the Right Tray for Planting

Choosing the right tray for planting turnip microgreens is crucial. Here are a few things to keep in mind:

• Size: The size of the tray will depend on how many microgreens you intend to grow. Standard 10x20 trays are commonly used.
• Depth: Trays should be at least 1-2 inches deep to accommodate the roots and the soil.
• Drainage: Ensure the tray has drainage holes. Proper drainage is essential to prevent waterlogging and the diseases it can cause, such as root rot.
• Material: Trays made from durable, food-safe materials are the best choice. They should also be easy to clean, as hygiene is paramount when growing microgreens.

Different types of trays can be used for planting turnip microgreens. Here are some of them:

10x20 Tray	This standard-size tray is commonly used by microgreen growers. It provides ample room for seeds to spread out and grow.
8x8 Tray	A smaller, square tray like this can be ideal for home gardeners who wish to grow smaller batches of microgreens.
Stackable Trays	These trays are designed to stack neatly on each other – a valuable feature during the blackout period when you can stack another tray on top to block out light.
Tray with Drainage Holes	Drainage is key to preventing waterlogging and subsequent disease in your crop. Trays with built-in drainage holes help maintain optimal moisture levels.
Solid Tray	A solid tray, when used in conjunction with another tray with drainage holes, can create a reservoir where excess water can drain off, preventing soggy soil conditions.
Microgreens Tray	This is a tray designed specifically for growing microgreens. It often has grooves or a patterned bottom to help funnel water and prevent waterlogging.

Ensuring Proper Soil Moisture and Water Level

Proper soil moisture is critical when growing turnip microgreens. Here are a few tips to maintain the correct water levels:

• Watering Method: Watering with a spray bottle ensures a gentle, even spread of water that won't disrupt the seeds or seedlings.
• Moisture Level: The soil should always be moist but never waterlogged. If the soil is too dry, the seeds won't germinate; if it's too wet, the seeds could rot.
• Drainage: Ensure your tray has adequate drainage holes to prevent water from accumulating at the bottom. This helps keep the overall water level balanced and promotes healthy root growth.

Managing the Growth of Turnip Microgreens

Understanding the growth stages and implementing appropriate measures at each stage can greatly enhance the success of your turnip microgreen cultivation journey.

1. The Blackout Period and its Importance: In the early growth stage, turnip microgreens require a blackout period of about 4-8 days. This period recreates the conditions under the soil surface, encouraging stronger stem growth. Keeping trays in a cool, dark location during this time ensures the best growth environment for your microgreens.
2. Managing Light Exposure: After the blackout period, your turnip microgreens need light for photosynthesis. Whether natural light from a sunny windowsill or artificial light from a grow light, ensure that your microgreens receive at least 4-6 hours of light each day. Position the light source close to the trays, preferably 1-2 inches above, to prevent the seedlings from growing too tall and thin.
3. Understanding Growth Stages: Recognizing the different growth stages can help you cater to the needs of the turnip microgreens more efficiently. From the germination stage, where you'll see little white stems pushing up the soil, to the seedling stage, where the first "true leaves" appear, each growth stage requires specific care. Regularly monitoring and adjusting light, water, and temperature conditions will help ensure healthy growth throughout these stages.

Harvesting Your Turnip Microgreens

• Knowing When to Harvest

Turnip microgreens are usually ready to harvest when they are about 1-2 inches tall, typically occurring between 10-14 days after planting. The main visual indicator that your microgreens are ready for harvesting is the appearance of the first pair of "true leaves." These look different from the seed leaves and signal that the plant has moved past the seedling stage and is maturing.

• How to Harvest Turnips without Damaging the Plant

To harvest your turnip microgreens without causing damage, you’ll need a sharp, clean pair of scissors. Begin by gently holding the stems near the base. Cut the stems just above the soil level, taking care not to pull or disturb the soil. Please do not wash the microgreens until ready to use them, as moisture can make them spoil faster.

• Post-Harvest Care and Increasing Shelf Life

After harvesting, if you're not using the turnip microgreens immediately, store them in a container with a lid in the refrigerator. Place a paper towel in the container to absorb any excess moisture to extend their shelf life. Properly stored, your turnip microgreens can stay fresh for up to a week. Remember always to wash your microgreens just before use rather than before storage.
