What Is Intensive Planting and Does It Work? • Gardenary (2024)

Intensive Planting Means Breaking the Plant Spacing Rules

You know how eager little children are to call someone out when they're doing something wrong? I feel like many of my followers who see the way I plant my own garden or a client's garden on social media are like kids who've just seen their sibling drawing on the walls with permanent marker. "Wait a second! You're breaking the rules!"

I practice something called intensive planting in my gardens, and it basically means ignoring the plant spacing suggestions on plant tags. People can get pretty opinionated and even mad about this when they see my gardens, as evidenced by the hundreds of messages I receive from gardeners who want to turn me into the plant spacing police. Here's an excerpt from just one of those emails:

That's right. I am a rule breaker, and I'm going to teach you how to break the plant spacing rules too—and why it's okay to ignore the plant tags.

Let's get intense about our plant spacing.

I WANT YOU to Break the Plant Spacing Rules with Me

You too can commit to being an intensive planter by taking the Intensive Planting Pledge. Oh yeah, girl, there's a pledge and everything. But before you take it, I do want to say that intensive planting is not for everybody, and I'll tell you why in a bit.

For me, I personally love the idea of breaking the rules because I've been a rule-follower all my life. I feel guilty if I do anything other than the way I'm "supposed to"—except planting. This is one of those times you can break the rules and you don't have to feel bad about it. (Come on, you know you want to.)

Here's an excerpt from Chapter Six: "Plant" of my first book, Kitchen Garden Revival:

"I'm going to come right out and say it, okay? You can pretty much ignore the plant labels. Because guess what? The plant tags in nurseries weren't created for kitchen gardeners. The plant tags tell you how far apart your plants should be if—big 'if' there, guys—you're growing crops in long and wide rows on a farm or a large in-ground vegetable patch, not in a raised bed in your backyard. So, when the tag says something like, ‘Space three to four feet apart in three-foot rows,’ it's talking to the farmer who will have 40 or 60 feet of each planting row with 20 or 40 or more plants along the hill.

“Is this you? This isn't me. And this is not a kitchen garden. Don't get me wrong. I'm so thankful we have farmers who farm in rows and plant lots and lots of food. We need more of them. This is in no way meant to disrespect the farmers who plant in rows. Farmers, if any ofyou arereading this, please keep planting all the delicious things however you want, and I will buy them all. And please don't hate me for breaking the plant spacing rules.”

Three Reasons to Break the Plant Spacing Guidelines

It may surprise you to learn that I was once a very obedient gardener. That's right. I only started packing in the plants in my garden after several years of following all the advice on plant tags for spacing to the letter. I sowed my seeds two to three feet apart in rows 12 inches apart, or whatever the instructions said.

There are three reasons I began to regret following the rules.

One: Following the Plant Spacing Rules Means Not a Lot of Production

My first garden boxes were 4ft x 4ft. With just 16 square feet of total growing space, following the plant spacing for tomatoes meant I only had room for four, maybe five, tomato plants—and that was it. I waited months for those little tomatoes to ripen so I could finally have something to harvest, only for squirrels to steal most of my fruits. In short, I got very little production out of the space.

Two: Bare Soil Invites Weeds

When you space plants super far apart and don't grow anything in between, that means there's a lot of soil left exposed to the elements. Bare soil dries out more quickly and is overall more difficult to manage. When the soil was bare between my sad little tomato plants, I was constantly having to water. On hot Houston days, I often had to water twice.

The worst part was that things grew in those open spaces whether I planted them there or not. Those things were weeds. You see, weeds love the extra access to sunlight they get when you leave nice, empty places for them to fill. Weeds are not something I wanted to eat, but there they were, growing between the plants I did want to eat.

Three: I Got Bored

Having four of the same type of plant in a box—and nothing else—just wasn't enough to keep me coming back to the garden on a regular basis. I found tending those tomato plants a chore, when what I really wanted was for my garden to be a place where I could practice a new hobby, be entertained, and learn something constantly.

So I Tossed the Plant Spacing Chart out the Window

After several seasons of growing sad, solitary tomato plants amid dozens of weeds, I had a realization. If bare soil is hard to manage and smaller plants want to grow in those empty areas, why not just plant smaller plants I actually want to eat in that space? Those plants will protect the soil so that I don't have to spend as much time watering and weeding. Plus, I could actually get to harvest something while I'm waiting on the tomatoes to form, instead of banking the entire growing season's success on just four tomato plants. I could harvest more often from a wider variety of plants.

So, I started planting smaller plants around those tomatoes, and guess what? It worked! In fact, it worked so well that I started planting this way with all of my Rooted Garden clients once I started my garden consulting business.

Two Requirements to Practice Intensive Planting

Intensive planting is great, but it's not for everyone.Before you toss out the rulebook too, make sure you and your garden space meet these requirements.

Intensive Planting Is for Raised Garden Beds

Intensive planting does not work for in-ground gardens. The extra depth provided by a raised garden bed is key to growing plants closer together. Trellises are also important to help you maximize space by growing climbing plants up instead of out.

Intensive Planting Is for People Who Tend Their Gardens Regularly

Intensive planting does not work for people who don't have the time or intention to tend their gardens regularly. You can't pack in your plants and then forget them for a month. You have to be ready to plant, water, fertilize, prune, and harvest a little bit every couple of days.

Intensive Planting Allows for More Variety in the Kitchen Garden

Following the spacing rules often means you get nothing to show for it. I learned my lesson with those tomatoes, and when I set up my next garden, I realized there were so many things I wanted to grow there. Two problems: There are only 60 to 90 days in a growing season, and I only had so much space.

These limits pushed me to be more creative and try things I otherwise wouldn't have tried if I'd had rows and rows of space. I started squeezing herbs and flowers around the edges of my raised beds and then packed the area between those smaller plants and the large plants in the middle with leafy greens and medium-size plants. I could now grow a dozen different plants in the same space that used to host just one. (Check out the article below to get a better idea of how many plants a 4ft x 4ft garden can actually fit.)

If one plant doesn't do well one season, it's okay because I still have herbs, leaves, taproots, and fruits from other plants. Variety is the spice of gardening.

Intensive Planting Is the Best Way to Imitate Nature in Your Garden

Have you ever seen plants growing naturally in their habitat all spaced apart from one another with lots of soil in between? I'm waiting.

No, you haven't because it's not natural. Unless you're in the desert, but even in the desert, if you stumble upon a plant, it's typically growing next to other plants.

You often see towering trees next to medium-size plants with lots of low-lying smaller plants all around. They all work together so they can thrive and reproduce. When we grow our garden that way, we're imitating nature, which is what we want to do in the first place.

Intensive Planting Helps with Water Retention

Remember what I said about bare soil being bad? Plants in exposed soil are more likely to be stressed, whether from running out of water or nutrients or support. We learned during the Dust Bowl and many other environmental challenges just how bad exposed soil can be on a larger level. What we want is soil to be covered. Intensive planting is like a blanket for the soil; it protects it. It helps the soil hold all of its nutrients and water.

If you feel like you're always having to water your garden because your soil is drying out too fast, that could be because your plants have too much space between them. There's just too much exposed soil, and the water in that soil is evaporating much faster than it would if it had plants growing in it.

Intensive Planting Helps with Weed Management

As I mentioned, things will end up growing in those empty spaces, whether you want them to or not. If I see a weed growing somewhere, I pull the weed out and take that as my sign to plant something I actually want to grow there. Nature wants something to grow there, so why not add a plant that you'd enjoy harvesting from and eating, or a plant that you'd enjoy looking at, like a flower?

Intensive Planting Maximizes Production

I teach more on how to categorize plants based on their size and their duration in my book, Kitchen Garden Revival, and in my online gardening course, Kitchen Garden Academy. But basically, large and lengthy plants are the ones that will spend 60 to 90 days in the garden to produce. That means it's gonna be a while before you get to harvest from them, but you'll still need to tend them while they're growing.

While you're waiting to harvest, you could have smaller plants with a shorter duration growing underneath them. This not only ensures you'll get to harvest sooner from these smaller plants, it also keeps the garden interesting. Like I said, it's hard to be a “gardener” who goes out and takes things from the garden regularly if there's not a lot happening out there. I didn't love tending my four cherry tomato plants because stepping outside was like: “Well, there they are again. They're still cherry tomato plants, still growing.”

Now, I step outside and see Swiss chard, lettuce plants, carrots, peppers, beans, and peas—all these things growing down below while my tomato plants take off—and that makes it super exciting to head out to the garden each and every day. I get to harvest from many of these plants in 30 to 45 days while I'm waiting on bigger plants to finish up.

Packing in the plants means that you bring more interest to the garden and you're going to get to harvest more. I don't mean that you're going to get to harvest more from every single plant. What I mean is you'll get to harvest a wider variety and there'll be more things coming more often.

There isn't a right or wrong way to break the plant spacing rules, and the rule follower inside you might struggle with defying those plant tag authorities. But I dare you to join me in planting your garden as full as possible. But to fully commit, you have to agree to seven things. Without further ado, it's time to take the Intensive Planting Pledge. Raise your right hand and read the following aloud:

Number one: I will tend to my garden regularly, weekly, maybe even several times per week.

Number two: I will prune my garden regularly and use the harvests as often as possible.

Number three: If some plants are getting crowded, I'll remove the ones that aren't as important to me.

Number four: I will double check on my plants so they feel cared for, even though I have a lot of them in a small space.

Number five: I will be okay if not everything works out well, because I got to try growing lots of things all in one season, which means I learned way more than I would have if I had just grown a few rows of one or two things.

Number six: I will not be intimidated by rule followers who tell me I'm wrong for not following the plant tag instructions.

And number seven: I’ll message Nicole when I harvest so much more than any of my rule-following friends, but I'll do my best not to be too braggy.

Did you take the pledge? You might have noticed some negatives in the pledge, like having to remove plants that are too crowded. I'm not saying the intensive planting situation is perfect. What I am saying is that it sets you up to really enjoy the garden in a totally new way. You can't just let it go and do its own thing and expect to get perfect production from all the plants that you put in the garden. It's a different way of looking at gardening tasks and what you hope to get out of your efforts.

I love it, obviously, but like I said, intensive planting is not for everyone.

You Don't Have to Be a Rule Follower in the Garden

After you practice intensive planting for several seasons, you'll find a happy balance for how much you think is too much and how little is too little. There are still seasons when I wish I'd planted more and others where I'm handing kale off to neighbors. Even after packing in hundreds of plants, I still have surprises and disappointments. That's part of what keeps it interesting.

What do you think? Are you down for breaking the rules with me? I hope I've convinced you. At the very least, I hope I've inspired you to see the potential in your own garden space. It's okay to break the rules if you're growing in a raised bed kitchen garden. Maybe one day, you'll get a message from a fellow gardener that says, "Dear you, it appears that you are breaking the rules. Please tell me more... because it looks fabulous!”

I like to say if something's worth doing, it's worth being intense about it. So here's to breaking the rules in the very best way!
