What are Soil Blocking Trays?
Soil blocking trays are a simple and efficient way to start seeds, but before we dive into how they work, let’s define what they are exactly.
Benefits of Using Soil Blocking Trays
Using soil blocking trays can bring numerous benefits to your gardening endeavors. One of the most significant advantages is improved soil structure. When you use blocks made from a mixture of peat moss and vermiculite, they help to create a uniform consistency throughout the growing medium. This results in better drainage, aeration, and root growth, ultimately leading to healthier plants.
In addition to enhanced soil quality, using soil blocking trays can also lead to increased crop yields. By providing a consistent environment with optimal moisture levels, your plants are more likely to thrive and produce higher-quality crops. A study by the University of California found that plants grown in blocks outperformed those in traditional seed starting cells, resulting in a 20% increase in yield.
Another benefit of using soil blocking trays is reduced water consumption. The compact design allows for precise watering, minimizing waste and runoff. This not only saves water but also reduces the risk of overwatering, which can lead to root rot and other issues. By adopting this method, you’ll be able to enjoy a more efficient and productive gardening experience.
Common Applications of Soil Blocking Trays
Soil blocking trays are incredibly versatile and can be used in a variety of applications. One of their most popular uses is for seed starting. By using soil blocking trays, gardeners can start seeds indoors 2-3 months before the last frost date, giving them a head start on the growing season. This is especially useful for warm-season crops like tomatoes, peppers, and eggplants.
In addition to seed starting, soil blocking trays are also perfect for transplanting seedlings that have outgrown their original pots. By using a soil blocking tray, gardeners can gently transfer delicate roots without causing shock or damage. This is particularly important when working with tender plants like lettuce, herbs, and flowers.
Soil blocking trays can also be used to grow small plants directly in the tray. For example, leafy greens like kale, spinach, and arugula thrive in soil blocking trays and can be harvested continuously for weeks. With proper care and maintenance, these plants will continue to produce new growth throughout the season. By using soil blocking trays in this way, gardeners can enjoy a continuous harvest without having to replant or replace individual pots.
How to Choose the Right Soil Blocking Tray
When selecting a soil blocking tray, there are several factors to consider to ensure you’re getting one that suits your needs. The size and material of the tray should be your primary concerns. Consider the space where the seedlings will be placed after they’ve been blocked – if it’s a nursery or greenhouse, a smaller tray with a higher density may be sufficient. On the other hand, if you’re growing on a larger scale, a bigger tray with more capacity would be more practical.
The material of the tray is also worth thinking about. Plastic and metal trays are durable but can harbor diseases; they should be sanitized regularly to prevent this issue. Wood or composite materials offer better insulation and are often preferred for seed starting due to their ability to retain moisture. Consider the long-term cost and maintenance requirements when choosing between these options.
It’s essential to think about your budget, too. Different trays have varying price points based on material and size. Make a list of your priorities to help guide your decision-making process.

Plastic Soil Blocking Trays
Plastic soil blocking trays are a popular choice among growers due to their durability and ease of use. These trays are made from high-density polyethylene (HDPE) plastic, which provides excellent resistance to wear and tear. One of the primary advantages of using plastic soil blocking trays is their ability to withstand high temperatures without deforming or cracking.
This makes them ideal for use in hot climates or during peak growing seasons. Additionally, plastic trays are generally more affordable than other materials, such as wood or bamboo, making them a cost-effective option for large-scale growers. However, there are some disadvantages to consider. For example, plastic soil blocking trays can be prone to cracking over time if exposed to extreme temperature fluctuations.
They also lack the natural breathability of other materials, which can lead to root bound conditions if not properly managed. To mitigate these risks, it’s essential to choose high-quality trays with a thick gauge and consider using tray liners or inserts to improve drainage and aeration. With proper care and maintenance, plastic soil blocking trays can be a reliable choice for growers seeking a durable and efficient solution.
Biodegradable Soil Blocking Trays
When it comes to biodegradable soil blocking trays made from materials like coconut coir or bamboo, there are several benefits and drawbacks to consider. On the one hand, these eco-friendly options are a great choice for growers looking to reduce their environmental footprint. Coconut coir, for example, is a byproduct of coconut husks that would otherwise end up in landfills.
Using biodegradable soil blocking trays can also provide some unique benefits. For instance, they tend to retain moisture better than traditional plastic trays, reducing the need for frequent watering and helping to prevent root bound conditions. Additionally, these trays are fully compostable at the end of their lifecycle, eliminating the risk of microplastic pollution.
However, there are some limitations to consider as well. Coconut coir trays may require more frequent washing and maintenance than traditional plastic trays, and can be prone to drying out if not properly cared for. Bamboo trays, on the other hand, may be more expensive upfront but offer a longer lifespan than coconut coir options.

Plus, they can be composted at the end of their life cycle, reducing waste and the carbon footprint associated with traditional plastics.
Recycled material soil blocking trays, on the other hand, are crafted from post-consumer plastic waste. By upcycling discarded materials, growers can significantly reduce the amount of waste sent to landfills. These trays often feature a durable, food-grade coating that ensures they meet strict sanitation standards. Look for trays made from 100% post-consumer recycled content to maximize their eco-benefits.
When selecting wooden or recycled material soil blocking trays, consider factors like durability, ease of cleaning, and the potential for reuse or recycling at the end of their life cycle. With a little creativity, these trays can become an integral part of your sustainable growing operation.
How to Use Soil Blocking Trays: Step-by-Step Instructions
To get started with using your soil blocking trays, follow these step-by-step instructions carefully to ensure optimal results and a smooth workflow.
Preparing the Soil for Planting
When preparing soil for planting using soil blocking trays, it’s essential to get the mix right. The ideal pH level for most vegetables and fruits is between 6.0 and 7.0, but some plants like blueberries and azaleas require more acidic conditions, typically between 5.0 and 6.0.
To create a suitable soil mixture, you’ll want to combine topsoil, compost, and perlite or vermiculite. A general rule of thumb is to use one part compost, two parts topsoil, and one part perlite or vermiculite. You can also add a balanced fertilizer at a rate of 5-10-5 NPK (nitrogen-phosphorus-potassium) to provide essential nutrients.
Moisture levels are critical in soil blocking trays. The ideal moisture content is when the mixture holds together well but still crumbles slightly between your fingers. Overwatering can lead to compacted soil and reduced root growth, while underwatering may cause the soil to crack and allow weeds to grow.
Before adding the fertilizer or mixing the soil, it’s a good idea to test the pH level of your topsoil using a DIY kit or sending a sample to a lab for analysis. This will give you an accurate reading and help you adjust the pH accordingly.
Filling and Watering the Tray
When it’s time to fill and water your soil blocking tray, follow these steps to ensure your plants receive the right amount of moisture. Begin by pouring a small mound of the prepared soil mixture into the center of the tray. Use a gentle touch to spread the soil evenly throughout the tray, leaving about 1-2 inches at the top for watering.
Next, add the seedlings or transplants directly into the soil, gently firming the soil around their roots as you go. This helps prevent air pockets from forming and ensures good root growth.
Water the plants by slowly pouring water over the soil mixture in a gentle stream, starting from one end of the tray and working your way across. Avoid getting water on the leaves or seedlings to prevent fungal diseases.
It’s essential to maintain optimal moisture levels in your soil blocking trays. Check the soil daily, using your finger to test its moisture level. If the top inch feels dry, it’s time to water again. Aim for a consistency that’s like a damp sponge – not too wet and not too dry.
Remember, consistent moisture levels will help promote healthy growth and prevent pests and diseases from taking hold.
Transplanting Seedlings into Larger Containers
When it’s time to move seedlings from their initial soil blocks into larger containers, you’ll want to make sure they’re transferred carefully to minimize shock and stress. Start by preparing the new container with a well-draining potting mix, making sure it’s moist but not waterlogged.
Next, gently lift the soil block out of its tray using a blunt instrument like a chopstick or pencil, taking care not to damage the delicate roots. Place the seedling in the center of the new container and add fresh potting mix around the base, firming it down gently as you go.
Be sure to leave enough space between the soil level and the top of the container for proper watering and growth. A good rule of thumb is to provide at least an inch of clearance. Water thoroughly after transplanting, and keep the soil consistently moist but not waterlogged in the days that follow.
If you’re concerned about seedlings getting leggy or spindly from being in a small space, consider using a grow light to supplement natural light, especially during periods of low sunlight. This will help promote healthy growth and prevent stunted development.
Tips for Maximizing the Benefits of Soil Blocking Trays
To get the most out of your soil blocking trays, let’s dive into some essential tips for optimizing their use and reaping their full rewards. We’ll cover must-know strategies to streamline your workflow.

Controlling temperature and humidity levels is crucial when using soil blocking trays to promote healthy plant growth. When temperatures fluctuate excessively, it can cause stress on seedlings, leading to delayed germination, reduced yields, or even death.
To maintain optimal conditions, keep the area around your soil blocking trays free from drafts. Ideally, the temperature range for most plants is between 65°F and 75°F (18°C to 24°C). If possible, place the trays near a south-facing window to benefit from natural light. However, be cautious of direct sunlight, as it can cause temperatures to soar.
Maintaining humidity levels is equally important. Most plants thrive in humid environments, typically between 40% and 60%. You can use a humidifier or cover the trays with clear plastic sheets to create a mini-greenhouse effect. This will help retain moisture and maintain optimal humidity levels.
Regular monitoring of temperature and humidity levels ensures that your seedlings receive the best possible start. Keep a thermometer and hygrometer nearby, and adjust the environment accordingly to provide ideal conditions for growth.
Providing Adequate Light Conditions
When using soil blocking trays, providing adequate light conditions is crucial for healthy seedling growth. Soil blocking trays are designed to promote even root development and minimize transplant shock, but they require sufficient light exposure to thrive.
Seedlings need a minimum of 12-14 hours of light per day, with an intensity of around 20,000 lux. You can achieve this using natural light, but be aware that the amount of available light can vary depending on your location and time of year. During periods of low sunlight or during winter months, supplementing with artificial lighting is essential.
Consider using LED grow lights, which are energy-efficient and provide a broad spectrum of light. Place them 6-8 inches above the soil blocking trays to avoid burning the seedlings. Alternatively, you can use T5 or T8 fluorescent lights, but make sure they’re at least 12 inches away from the trays.
Remember, consistent and adequate lighting will promote even growth, strengthen stems, and increase yields. Monitor your seedling’s response to light by observing their color, shape, and overall health.
Managing Pests and Diseases
Managing pests and diseases is crucial when using soil blocking trays. Soil-borne pathogens like fungal diseases can easily spread through contaminated tools or equipment, while insects like whiteflies, thrips, and aphids can quickly infest young seedlings.
To prevent these issues, maintain a clean workspace by washing your hands before handling the trays and disinfecting any tools or equipment after use. Keep your nursery well-ventilated to reduce humidity, which can encourage fungal growth. Use row covers to protect plants from pests like whiteflies and thrips.
Regularly inspect your seedlings for signs of disease or infestation, and take action promptly if you notice anything unusual. Remove affected plants to prevent the spread of disease, and treat remaining plants with organic pest control methods whenever possible.
In addition to these measures, selecting disease-resistant varieties and maintaining optimal growing conditions can also help minimize pest and disease issues. By taking proactive steps to manage pests and diseases, you can ensure healthy growth and development in your soil-blocked seedlings. This will ultimately lead to stronger, more resilient plants that are better equipped to thrive in the garden.
