Planning your first garden can feel intimidating, but I want to show you a simple process that I use in my own garden design that breaks each step down into manageable pieces. This is a project I typically work on over the course of a few weekends here and there - it won’t necessarily take hours to complete, but it’s nice not to rush the process so you can modify and tweak things after giving yourself time to mull it over.

How to decide what to plant in your garden

I cover this in depth in my seed selection post which you can read by clicking here, but the key is to identify what foods your family eats the most of, that will grow well in your particular garden climate. This list is your starting point - all we have to do is assign each plant on the list to a particular spot in your garden layout based on a couple important factors, including what plants grow well together, what plants are natural “enemies”, the location of the sun on the land, and how many of each type of plant you will be growing. But I’ll cover all of that in a minute. First let's decide where your new garden should go.

How to decide where to put a garden

The best time to choose the location of your new garden bed is after about a year of careful observation, because this gives you a full year of seasons to notice and document the weather patterns (if an area tends to flood or dry out quickly for example) as well as the positioning of the sun throughout the spring, summer and fall. But if you’re reading this with the intention of beginning your new garden in a few days, weeks or months don’t fret! Some educated guesses can be made based on just a few days of observations.

First, note the direction of the sun. In a perfect world a north-south orientation is best for low-growing crops, allowing direct sunlight to reach both sides of the bed. For taller crops such as pole beans, cucumbers and tomatoes an east-west orientation works best. The sun rises in the east and sets in the west, so just pay attention to your sunrise and sunset locations and you’ll be able to orient yourself based on that.

Next, throughout the day you’ll want to pay attention to shade and shadows. For instance, is there a tall treeline that means a certain area of the land does not get full sun throughout the day? If you have a choice to plant in full sun, you absolutely should - however, this doesn’t mean that your shady yard is inhospitable to planting. You’ll just need to modify your list of crops you plan to grow to include only those who thrive in lower light conditions.

Finally, notice the slope of the land. Unless your yard is perfectly flat, you probably have areas that will be easier to transform into a garden than others. We’ll talk about what to do if all the land available to you is on a slope next.

QUESTIONS TO ASK YOURSELF WHEN GARDEN PLANNING:

What is the purpose of the garden? Is it for aesthetics, food production, or a combination of both?

What is the climate and soil type of the area? What plants are suitable for this type of environment?

What is the size and shape of the garden space? How much sunlight does it receive? What is the orientation?

What type of plants do you want to grow? Do you prefer perennials or annuals? Do you want to grow edibles or ornamentals?

What is your budget for the garden? How much money do you have to spend on plants, materials, and tools?

How much time and effort are you willing to devote to the garden? Do you want a low-maintenance garden or are you willing to put in the work to maintain it?

What is the style of the garden? Do you want a formal or informal garden? Do you prefer a wild and natural look or a more structured appearance?

What is your level of gardening expertise? Are you a beginner or an experienced gardener?

Raised beds vs in-ground

Now that you’ve picked the location for your garden, it’s time to decide if you want to grow food in the ground or in raised beds. Each method has its pros and cons. I chose to switch to primarily all raised beds this year because fighting weeds in-ground and bending over the soil was not working for my back any more with my arthritis. The downside is that this means I have to pay for the beds themselves as well as the soil/compost to fill them. If you’re on a budget and don’t have the same physical limitations as I do, gardening in ground allows you to benefit from the pre-existing ecosystem within your soil including worms and beneficial bacteria and also means your plants won’t need to be watered as often.

If you’re gardening on a slope, I strongly recommend raised beds. With raised beds that sit on the earth you will be able to actually dig the base of the bed into the soil to make it even, effectively creating a level surface on which to plant. Just be mindful not to locate any plants that are sensitive to root rot at the lowest point of your slope since rainwater will collect most easily there.

How many vegetable plants do you need per person?

This is highly individual depending on your family and what you like to eat. You should definitely prioritize space in your garden for the foods you eat the most. For us, that means we grow a lot more broccoli, green beans and bell peppers than anything else. And no matter how much squash you THINK you will eat, one or two plants per household will probably yield more than you’ll ever be able to finish without sharing with your neighbors and friends. If you know you go through a lot of pesto, it’s a good idea to plant 20-30 basil plants. Refer to the chart below for some common amounts for popular vegetables.

What is companion planting?

Just as there are plants that do not grow well near each other because they compete for resources, there are many plants that get along quite well and actually offer benefits to their neighbors. You can harness this “companion planting” effect to grow more food in an even smaller space. You can also utilize taller, stronger plants to act as trellises for vining plants, prevent weeds by creating a thick overstory that will choke them out, planting certain herbs and flowers as a trap crop to repel pests, and benefit your neighboring plants with the addition of nitrogen fixing varieties such as snap peas or pull nutrients to higher levels for your shallow rooted plants with crops such as root vegetables.

Plants that grow well together:

There are countless companion plant combinations, but here are a few to get you started:

For “trap crops” to keep pests away from your plants or repel them entirely, look into basil, dill, marigold, mint, nasturtium, sage and zinnias.

Grow basil within 12 inches of tomatoes to increase your harvest. Basil also improves the flavor of lettuce.
Growing chives near your carrots will improve their flavor.
Beans like to grow with Beets, carrots, chard, cabbage, corn, cucumbers, peas, and radishes.
Strawberries like to grow with bush beans, chives, lettuce, onions, sage, spinach, and squash.

Plants you shouldn’t plant near each other:

Some plants compete with each other for resources or in the case of sunflowers for example, actively leech compounds into the soil that can cause harm to neighboring plants. Here are just a few common enemies in the garden.

What is crop rotation?

Crop rotation means that you intentionally do not plant the same type of plant in the same exact spot each year, you “rotate” it to a new location. For example, nightshades such as tomatoes are prone to microbial diseases that live in the soil. For this reason it is recommended that you do not plant in the same spot for 4 years after the initial planting. Other nitrogen dependent crops such as corn suck so much fertilizer out of the soil that you want to give the earth a break before replanting the same variety in the same spot. This will be more important in your second and following years of gardening, so don’t worry about it too much right now!

how to design your garden layout

Now that you have your final list of plants, your garden location and type and an overall understanding of the basic concepts of companion planting and how many plants you will need, the hard work is done! All we are going to do now is effectively “fill in the blanks”.

All you will need is some paper and a pencil, but if you want to get really crafty with it, print out some graph paper and grab your highlighters too.

Start by drawing out the outline of the shape and size of the garden beds you will be creating. I like to do this to scale with graph paper where each square equals a square foot of the garden. You don’t need to get this precise with it - if you have a 4x4 area or raised garden bed, just draw a nice sized square on your blank paper and add your own grid lines or rows as you see fit.

Now go back to your plant list of everything you plan to grow this season. Assign each plant on the list a letter from A to Z. You should also write down the number of plants for each item on the list next to the plant name.

All you need to do now is just fill in your blank garden squares with the corresponding letter for each plant to assign it a location and the number of plants you will be planting in that square.

That’s really all there is to it! Once this is complete I like to go back and reorganize the plant list based on when I need to start the seeds and transplant into the ground after our last frost, but that’s a conversation for another day.
