The late American garden writer, Mel Bartholomew, really made a splash with his concept of the square–foot garden, now adopted by home gardeners all over the world. The idea is to concentrate plantings to get the most vegetables possible in a limited amount of space. Gone are rows, designed more for walking in than gardening and great wasters of space. In a raised bed 4 feet by 4 feet square (1.2m x1.2 m), you can reach all the plants from one side or the other, so you never need to put a foot in the garden. So, bye-bye rows! With them gone, it means all the space can be used for vegetables.
To better use all the space, he recommended planting by squares one foot (30cm) long and wide. Thus “square foot gardening.” Each square would contain 1 extra–large vegetable, 4 large ones, 9 medium ones and 16 small ones.
I personally don’t follow square–foot gardening by the letter, but I have been densifying my plantings for decades, based on an older and less precise system called the French intensive system, generally with longer beds. Still, Bartholomew’s square foot calculations come in very handy.
Here is a list of recommended spacings based on his method with a few personal modifications. You may find them handy in planning your own vegetable garden. I’ve also included the height of the plants (based on their height at normal harvesting time), as you also need to know which ones might be shading out their neighbors.
4″ plant spacing = plant 9 in each square.6″ plant spacing = plant 4 in each square.12″ plant spacing = plant 1 in each square. Some plants (such as melons, large squash, and tomatoes) require more than one square, depending on how and where you plant them in the bed.
If you're building more than one raised square-foot gardening bed, leave enough space between them to roll a wheelbarrow. The formula for planting is simple: one extra-large plant per 1x1-foot square, four large plants per square, nine medium plants per square, and 16 small plants per square.
Some crops, like large, indeterminate tomatoes, need more space than a single square foot—otherwise they'll start stealing nutrients and water from other plants. Plus, plants can deplete moisture and nutrients quickly in a square foot garden due to the intensive planting technique.
So, How Many Carrots Per Square Foot? In this gardening method, carrots are sown at a rate of sixteen plants per twelve-by-twelve-inch square – that's to say, sixteen per individual grid section, with each planted three inches apart from each other.
3″ plant spacing = plant 16 in each square.4″ plant spacing = plant 9 in each square.6″ plant spacing = plant 4 in each square.12″ plant spacing = plant 1 in each square.
SFG recommends planting one indeterminate tomato per square in the grid. We're assuming you're attaching your trellis to the north end of your raised bed and that the tomato is planted in those adjacent squares.
The other rule of thumb when using this layout plan is to organize your spacing so that your tallest growing vegetables are planted on the north side of your rows. Follow them with medium height vegetables, and then plant your shortest crop on the south side of the rows.
Think of it like your bubble of personal space. Just like you don't want to be crowded, neither do plants. In addition to the pruning and space issues, crowding can increase the likelihood of disease or other plant issues.
There are two basic rules when arranging plants in the beds: 1) space the individual plants so that they touch each other when they reach their mature size, and 2) overlap the masses of plants and connect them so that they flow without space between them. Avoid gaps or large open areas between masses.
You can comfortably grow two cucumber plants, spaced 6 inches apart, within a square foot. You may think that's not much, but take into consideration that cucumber plants are vigorous vines that can produce approximately five pounds of fruit per plant.
Square foot gardening is the practice of dividing the growing area into small square sections. The aim is to assist the planning and creating of a small but intensively planted vegetable garden. It results in a simple and orderly gardening system, from which it draws much of its appeal.
With the square-foot gardening method, you plant in 4x4-foot blocks instead of traditional rows. Different crops are planted in different blocks according to their size; for example, 16 radishes in one square foot, or just one cabbage per square foot. A lattice is laid across the top to separate each square foot.
Marigold seeds are planted 1/2 inch deep, 4 per square foot, in the full sun. Take care to notice what plants are around the area as well, see the companion plant section below. Your seeds should sprout within 14-21 days. You will need to provide your marigolds with consistent moisture.
1, plant per 1 square foot is very tight). Second Sow seeds or transplant about 3 inches away from the stake on the south side of the stake. Once the seedlings come up, mulch the Zucchini plant with wood mulch or dead leaves. The last step is to remember to harvest frequently.
I always recommend planting chives, garlic, onions, leeks, or shallots next to your carrots and leafy greens. The reason being, these members of the onion plant family have a strong scent that repels pests like aphids and carrot flies. Chives are also said to improve the flavor of carrots growing nearby.
Included in every description is a suggested spacing. Example: you want to cover an area of 120 square feet with a spacing of 10". For 10" spacing the plants per square foot is 1.45. Multiply 1.45 x 120 and you get 174 plants needed.
Most cultivators utilize roughly 70% of a room's floor space as the canopy. In this scenario, a 10 x 10 room can hold up to 70 plants. Efficient facilities take advantage of tiered growing systems. Each tier increases production capabilities and can triple a room's canopy.
A typical 10'x10' garden space you could grow the following: 3 indeterminate tomatoes or two tomatoes and 1 cucumber on a trellis.4 eggplants. 5 peppers.
A 4ft. x 4ft. raised garden bed gives you 16 square feet of growing space (more if you add some trellises for vertical space). That means you can grow around 10 to 11 indeterminate, or vining, tomato plants in one raised bed—if you really love cherry tomatoes, that is.
