Soil blockers are an alternative to trays and pots and are widely used to transfer seedlings and achieve concise germination quickly. Additionally, soil blockers are one of the most efficient methods for seed growth as they save time and expense at the same time.
While trays were used to do the same thing, they were highly inefficient and had troublesome requirements.
However, with soil blockers, one can easily deal with the seedlings without worrying about certain problems like the roots breaking out of the soil block.
So, the purpose of having a soil blocker is to create a “pot-less – pot” from the soil itself. This not only saves the money spent on plastic pots but is also environment-friendly. Moreover, soil blocks, or rather soil pots, are more efficient and promote faster growth and speedy germination of seeds.
Here are some of the most widely used soil blockers in the market by simple gardeners:
This is what you should know about Ladbrooke’s Genuine Mini 4 Hand-held Soil Blocker,
Ladbrooke’s Soil Blocker is one of the most famous soil blockers in the market. The blocker has all the basic features that a good soil blocker must include.
Speaking of features, the blocker is made of zinc-coated steel, so it won’t get any rust even when dealing with harsh and moist environments.
The blocker is handheld and fairly lightweight. Although it has a comparatively stiff handle, it does the job well.
The hand-held soil block maker makes four 2″ soil blocks with a seed dibble pre-formed at the top. Potting soil is compressed wet into the soil block mold and then discharged into a tray with the ejection handle. These soil blocks can later on be used to store and germinate seeds.
Using soil blocks works well and is easy to operate. It does not require much effort to make the soil blocks.
The size is configured to be 2 inches and it can’t be changed.
In one step, four Soil Blocks are produced that have the seed bay in them by default. Wet soil is used in operation.
You do need to use special soil to get the blocks to stay together, but it’s quite easy to achieve.
You just need the following: one part of peat moss or coco coir, one part of perlite or vermiculite and one part of finished compost.
Mix all of them up dry, then put on some rubber gloves (the kind you’d wash dishes in) and start mixing in water. Better too much water than too little, but ideally you want to be able to squeeze a handful, open your hand, and have it hold its shape. It’s a messy affair, like making mud pies.
Overall, this product is recommended due to its easy operation and just the perfect soil block size. Small plant nurseries and homeowners can make good use of this product.

Keep the following review in mind about Ladbrooke’s Soil Block Maker – Multi 20 Commercial Long Handle,
Another product designed and manufactured by Ladbrooke comes with industrial-level features and a versatile area of operation.
Unlike the Mini-4, Multi 20 has the capability of making twenty soil blocks at a time instead of just four.
The size of soil blocks is configured to 1.5*1.5 inches and can’t be changed in any way.
This makes it usable for various small industries such as plant nurseries or high-end gardening firms. This soil blocker can perform excellently and last longer without rusting with zinc plated iron casting and efficient design.
However, there is one slight change in its design apart from 20 soil blocks – it’s the handle. The new and long handle helps generate more torque and considerably increases the pressure applied to each of the soil blocks, resulting in good quality soil blocks.
The seed bay is built in the soil blocker, so all the soil blocks will get the seed bay pre-made.
Now while working with this particular soil blocker, you will feel that it is heavier than normal soil blockers because of the twenty soil blocks setup present in the bottom.
The soil blocker works on the same principle as the Mini-4 and can produce good quality soil blocks.
The seed bay is also well crafted, so you won’t have to make holes to put in your seeds afterward. Multi-20 soil blocker is almost directly targeted for consumers with high requirements or commercial vendors.
The overall feel of this product is very stiff and there is no bending observed in its operation which shows the quality of materials used in its construction.
It must be noted that due to its size and weight, this soil blocker is fit to use on the floor. The long handle serves its purpose here and can be gripped and used easily.
Above all, this product is safe to be recommended to high-demanding people and plant germinating industries that deal with a lot of seeds and require fast-paced working tools.

Read the complete review about Soil Block Maker 4″ Maxi,
This soil blocker is one of the largest soil blocks producing models in the market and can be used to craft 4-inches soil blocks.
This size means you’re going to be filling it with a lot of soil as compared to all the other soil blockers. The soil mix itself will take a lot of resources and you’ll have to put some real effort into it.
This model is also designed and manufactured by Ladbrooke and like all of its products, Maxi comes with a steel body covered by a zinc coating to save it from rust.
The Maxi soil blocker is perfect to use if you are transforming the 2-inch soil blocks from mini-4 however using it for seedling is not recommended. (It doesn’t mean you can’t use it for seedlings.)
Before you think of buying this product, you should know that it is targeted to a particular usage and is not something you will use very often in your greenhouse or garden. So, it becomes essential that you only buy it if you need it.
Another thing is that this soil blocker is huge and cannot be used very easily. This can be their worst nightmare for starters, as creating soil blocks is extremely difficult even for regular soil-block makers.
It might require you to have considerable practice before doing the blocking process in the right way.
There’s another factor of the soil mixture in which composition due to the large block size can vary place to place depending on the soil type of that area. You’ll have to rely on hit and trial methods to find the correct composition of the soil composite. This is a time-consuming and difficult process, so you will have to be a “pro” if you are planning to use Maxi soil blocker in short.
It must be noted that this soil blocker produces only a single product and if you have a large number of blocks to produce, you will have to sit for a considerable amount of time.
Meanwhile, the block can also be used to incase 2” soil block. Like Mini-4, no inserts are required to make a seed-bay in Maxi as well.
The large size of the soil block may cause it to crumble/crack from the base, which can be corrected if you apply ample pressure on the soil blocker and use the correct soil-composite/mixture.
In the end, this soil blocker is only recommended to those who deal with big soil blocks and are experienced germinators.

This is a detailed review about Ladbrooke Genuine Micro 20 Soil Block Maker,
One of the most exciting tools from Ladbrooke, Micro 20 meets all your tiny seeding needs.
This is a perfect soil block maker if you have tiny seeds that do not require a large soil block to thrive. Once properly set up, this soil blocker can produce about twenty ¾ inch soil blocks that are pretty faced paced.
The soil blocker is made of a zinc-coated steel body like all other soil block makers from Ladbrooke and features an ejection handle as well as built-in inserts for making seed-bays in the soil blocks.
This soil block maker is one of the most efficient gardening tools available, inexpensive and maintenance-free!
The most relevant application for this type of soil blocker is when you are dealing with tiny seeds that require smaller-sized soil blocks for their growth.
They provide a high rate of germination and easy blooming. So, they are ideal to be used for the right type of seeds. Most of the time, this is the only reason they are used because gardeners can’t fit the seeds in 2-inch or 1.5-inch soil blocks.
However, there is one serious drawback of using this size of soil blocks and that concerns directly to the growth factor and one of the most important ingredients for a seedling – moisture.
For some people, this size will be too small to handle and might not give them the best experience.
Small soil blocks tend to dry quite quickly and they are the hardest to water, which makes them a tough choice for gardeners. Practicing and self-education can help you craft the seeds in ¾ inched soil blocks pretty easily.
Watering too harshly may cause the soil block to beak and the tiny seeds will wash away if you water too little. The seed might die from dryness. Therefore, using a gentle sprinkling method is recommended to water the seedling as it is safer than using a water jet stream.
Keep in mind that you should not water too much or too little, depending upon the type of seed you are using.

These questions are frequently seen on the internet about Soil Blockers:
No, there is no specific good or bad soil blocker as different blockers are fit for different purposes. You cannot simply specify a single blocker for all types of scenarios. Therefore, the choice of a perfect soil blocker essentially depends on the consumer’s requirements and may vary from person to person.
It grows good quality seedlings. Since the plant is not in any sort of vessel, it does not become root-bound and because of the structure of the blocks and blocking mix you can handle the transplants when they are younger establishes plants in the garden even faster. The plants that perform poorly when they become root bound grow especially well with soil blocks.
Special soil mix is not required to make soil blockers, however, be sure to make or choose a soil mix that contains materials that hold water, are fibrous and that allow for air spaces.
One of the most important steps in making blocks is to moisten the soil mix beforehand. When using containers, many people fill these with dry soil mix; however, this method does not work for soil blocks. Wet the soil mix for several hours before making blocks and moisten the mix to a slurry-like consistency.
Place the mix in a container with sides so that the top level is higher than the soil blocker height. Thrust and twist the soil blocker into the soil mix a few times until the soil mix fits snugly into the chambers.
At first, water blocks with a fine rose or mister to prevent structural damage to the block. Once the seed starts growing, the roots will hold the soil mix in place and then a regular sprinkler can be utilized. Make sure that blocks never dry out as the moistness helps hold them together and they can be difficult to re-wet.
Water all parts of the block, not just the tops. The blocks on edge will dry out first; make sure to water them thoroughly and even protect them from windy conditions by placing a board or border along all exposed edges.
You can fit three rounds of the Multi 20 soil blocks into a 1020 tray. There will be room left along both the long edge and short edges of the tray. The Multi 35 Soil Blocker was designed to best fill a 1020 tray. It was designed in cooperation with US customers after the other long-handled soil blockers were already in distribution.
The Multi 20 with 1.5″ soil cells is not recommended for cubic inserts. The cell walls generally are too thin and will likely crumble with that cube insert. The cells are just slightly too small to be optimal for this purpose. The Multi 12 and Multi 6 long-handle soil blockers can take cubic inserts.
The Multi 20 comes with 5/8″ seed pins in each soil block square. Longer 1″ seed pins are available in sets of 4, only if you want a little longer indentation but not necessary to use this.
It depends on your seed. Some seeds need light to germinate and some do not. Also, the size… If you drop a tiny seed in a comparatively deep hole, it has to struggle to sprout.
It depends on the type of seed you are using. Ideally, seeds germinate under dark or very dim light conditions. However, some specific seeds require light to grow.
Suitable temperature, moisture, water, sunlight, and fertile soil are necessary for a seed to germinate.
The fastest way to germinate seeds is to place them in a food container or pour hot distilled water over them. You might want to check whether your seed prefers hot or cold water before doing the above.
Seeding too deep, planting them in colder soil, extra watering, improper soil, birds, squirrels or insects, and poor seed quality are the most common causes behind non-germinating seeds.
