Square greenery can be a great way to produce a lot of food in a compact space. The added benefits are that we don’t walk on and compact fixed beds, and the general trend in gardens is to collect a variety of plants – essentially the planting and the corresponding crop variety – and create fixed beds.
We can achieve these benefits even if we do not plant exactly as in the usual Square Foot Gardening Guide, for example by using much smaller irrigated planters and containers or by adjusting the width and length of our flower beds.
However, there are certain aspects of gardening per square foot that we need to consider in terms of self-sufficiency and longevity and our physical capabilities and costs, both up front and in the process.
Square gardening requires rich mixtures
The success of Square Foot Gardening is based on a fairly specific mix, as are systems like Eden-style gardening and some of the Bio-Etho and Bio-Etho methods.
To garden per square foot, Mel’s Mix (the manufacturer) requires one-third compost, peat moss and vermiculite.
This could be an expensive start (only 8k for a 4x4x0.5′ box).
Mel Bartholomew is the inventor of the Square Foot Gardening System.
We can replace some elements, and it is not necessary to do this completely every year, but without this special light mixture, which retains moisture and is rich in nutrients, the flower beds cannot support very dense plantings or larger, heavier forage or crops that suck up moisture.
The specific crops we grow, the number of rotations and length of season for alternative crops, as well as rainfall and irrigation, all affect the removal of nutrients from our beds. Some can go 3-4 years or more without revitalization without any nutritional problems. Others notice problems as early as the second growing season.
Depending on location and use, it may take 2 to 5 years before a decline in growth performance and plant yield is noticed due to soil structure.
Then gardeners – especially preparers – should think about how to handle this mixture.
Mixed cosmetic products and cosmetic substitutes for horticulture and gardening
Vermiculite lasts the longest without decomposing and is absolutely essential for maintaining aeration and drainage in 1/4 to 1/3 peat mixtures. Sand can help fill the soil thanks to the clarifying role of inert vermiculite.
Compost is an all-in-one product for the garden because it contributes both to positive soil structure and nutrients. The more varied the composting ingredients, the broader the spectrum of nutrients available to our plants. Compost is the fastest carrying element in the Square Foot Gardening mix, but we have plenty of nutrients and repellents for structure.
We can make our own compost or have pests for watering and leaching/tea that we can use as liquid fertilizer or put on as mulch.
Comfrey waste under small fruit trees or in a window box can also be chopped into mulch, composted or poured into tea. (Do not put roots or seeds in the beds or compost).
Rabbits provide excellent manure for immediate application and compostable litter. Other animal waste can also be used, but most must mature within 6 to 15 months.
Peat moss is also an important element. Not only does it retain and slowly release moisture several times, but it is also quite acidic (pH 4.2-4.5).
This acidity is often neglected in replacements.
Most edible annuals and many perennials require a substrate with a slightly or strongly acidic pH. Vermiculite and compost are in a near neutral range, with the pH of vermiculite at source ranging from 6.0 to 9.5 and becoming increasingly alkaline over time.
If we use coir and snow covers to improve soil structure instead of drawing from sphagnum bogs, we also need to find a way to balance moisture needs and maintain pH.
Mulching pine or oak leaves can maintain both pH and soil structure, but only when they begin to decompose. Olla-like drip irrigation or reservoir irrigation can help mitigate the effects of dehydration and labor without using sphagnum moss.
Shape and size of the square foot of the garden
Mal’s standard for gardening per square foot is based on a 4×4 1′ square grid, but we are not bound by that. Square foot gardening techniques can be applied to all shapes, including window boxes. In fact, we may want to change this form, although we have room for it.
The garden squares are divided into 1-foot squares. The garden squares are divided into 1-foot squares.
The 4×4′ design offers a good ratio between the seating surface and the kerb. Four-foot spans are a fairly common suggestion for maximum bed width, consistent with the assumption that most people can reach two feet in the middle fairly easily for planting, weeding, watering and harvesting.
In practice, it is not easy for everyone.
There is a reason why many professional gardeners and landscapers work on 30-36 inch beds.
To test it out, grab a free wooden shipping tray or a kiddie pool and see how easy it is to play with the center without leaning too hard on the edges. (They have many uses if we don’t want them in our gardens).
If we’ve already built your raised beds and find that we can’t access them easily, we can reassign them to things that require less maintenance or are easier to access.
As an option, you can fill the 18-24 interior with a bottomless pot or container for a pollinator, mosquito, resource or ornamental plant or even a dwarf berry or fruit tree or shrub.
There are many ways to configure your garden beds in square footage.
We can also use the space for a compost tube, a bucket and irrigation pipes, a bird bath, a bug motif, or a bucket or barrel to collect rainwater (comb, cover with cloth, or line with sticks, boards or slabs if it makes a difference in attractiveness).
If we know in advance, we can easily change the size of the bed. A 3×5′ or 2×8′ bed produces the same quantities as the original 4×4′ bed.
If we have the necessary space, the lengths of 8 and 12-15 inches are very practical for hobby gardeners.
These 2 to 3 foot wide lengths allow for a good combination of deck space without interference from building materials or sidewalks, while still being easy to maneuver.
They are also easy to plan and harvest over time across the area, and they remain effective when grown as block crops (sweet potatoes, corn, millet) or mounds of older sisters/three sisters in rotation with vegetables.
We can also apply angles and curves to create keyhole L- and U-shaped beds that use the space equally or even more efficiently, depending on the space we need to work.
Again, we can easily transfer Square Foot Gardening mixes and methods to containers and planters.
Landscaping considerations for Square Footage Construction
In horticulture, we generally see boards 1-2 inches wide. Even with the corner posts, it doesn’t take up too much space.
The type of material and our climate determine the lifespan of these beds. When using wood, it is not unreasonable to build a second box to extend its life.
We can certainly use logs, CMU blocks, landscaping and construction lumber, bricks, glass bottles and other deeper, harder and more durable materials. Remember, we have to stay within that 4 foot width or we won’t be able to get in the middle without going in.
Because they occupy the interior space of the revegetation, we must also measure to form a grid of revegetation density per square meter.
Gardening Square foot soil barriers
Square footed gardening generally requires a 6 inch bed. If we put up weed barriers, some plants will not be happy. Some will easily grow to 3-4 inches, but many will not thrive – even with such a rich mixture – without at least 8 inches. If there is no soil, they can reach the ground below to create additional root space.
Access to soil also reduces one of the main stresses associated with container gardening and flower beds: Irrigation.
Even with this rich mixture designed to facilitate root access and water retention, dense plantings and especially some crops can be water hungry.
* Dense plantations make efficient use of water, shielding the soil and preventing evaporation. They use less water than long rows of crops with bare soil, but we have to apply them more often.
Some crops are particularly sensitive to complete desiccation (lettuce) or daily flooding cycles (tomatoes). Others prefer and really need a situation where they only get deep water every 3 to 7 days, while surface water is abundant 1-3 times a day (squash).
The downside: Without a fence, weeds have it easy, even if we invest time and effort in clearing, covering or removing the grass for construction.
When it comes to bedding, it depends on what we want to do: Watering or weeding.
Many landscapers end up getting higher and higher. Here’s one, along with a few other points about blending square footage and how to incorporate and water the rest of the property.
Increasing height has many benefits, from weed and moisture retention to space in the root zone. We can fill in the soil first to save soil costs, or fill it with leaves, straw, etc.
If we choose a single layer of 6 to 8 high, try to choose a material and construction that makes it easier to add another layer later to avoid reconstruction.
Some square foot hobby gardeners have a permanent one-inch net that attaches to the top of the bedstead. Turning wood, 1×1, cornice, old telephone wire, metal ties, fishing line, rope or string – you name it, it’s used.
Remember, we want to go there from time to time.
Weeding in the first year is already worth considering. Working soil for plantings in succession from the first year. A particularly important challenge is that at some point we will have to go back and mix and redistribute the soil components as things settle and rise in the coming years.
It’s also easier if we can get up and pull a rake to make small watering and seeding across the width/length of the bed.
If you tend to have physical and visual barriers, consider something temporary (but that won’t be an annual/seasonal change of funds – it’s zero) or build a product that can be easily raised and lowered. A PVC drip irrigation grid is an excellent option for those on a slope.
Square gardening for preparers
Square Foot Gardening has been around for many years and for good reason. In its original format, the mix of size and soil is easy to handle, fits into many lives and is very productive.
But they also have some drawbacks. Preparers need to think about activation. Fortunately, we have many options when it comes to cost, maintenance, durability and size. We just need to be aware of the limits so that we can prepare for them.
