In the world of gardening There is an abundance of advice passed down from generation to generation that forms part of the gardening mythswhich, although well-intentioned, can become a silent curse for your plants.
Many of these recommendations originate from word of mouth, isolated experiences, or misinterpretations of what plant species truly need. The result is a cocktail of practices that seem logical but, in the long run, cause stress, disease, and death in pots, gardens, and flowerbeds.
Faced with this tangle of myths and half-truthsIt's worth pausing, observing, and comparing. Just as in politics, economics, or social organization, in gardening there are also "arrogant discourses": categorical statements repeated without data, context, or listening to those who actually deal with the problem every day.
In the following sections, we'll debunk three major pieces of "popular advice" that are ruining gardens. We'll do so with a critical approach, drawing on practical experience and the need for informed decisions, not greenwashing. For further exploration of these issues, see other articles on [topic missing]. Myths and truths about cultivation.
Myth 1: “The more water, the better the plant grows”
One of the most frequent mistakes in home gardening It's thinking that abundant and constant watering is synonymous with affection and good care. This myth is as widespread as those political promises of "more aid for everyone" that banks later deny at the teller window: on paper it sounds good, but in practice it's a trap. Roots need water, yes, but also oxygen; Be careful with the roots It's vital. When the substrate is constantly waterlogged, the roots literally suffocate and begin to rot.
This over-watering It particularly affects those going through difficult times: the elderly, people with anxiety, families with little time who compensate for their absence by "watering a lot when they can." It's a bit like certain social policies that are announced with great fanfare and then fail to reach those who need them: the intention is good, but the implementation destroys the very fabric they were meant to protect. In the case of plants, the first thing to deteriorate is the root system, the foundation of everything.
When the substrate is permanently moist This creates ideal conditions for pathogenic fungi and bacteria. At first glance, the plant may appear wilted or yellowed, and the novice gardener interprets this as a lack of water, repeating the watering cycle and worsening the problem. It's very similar to mortgage holders who, pressured by the financial system, request more credit to plug a hole that the system itself has enlarged: each poorly planned "help" only sinks them a little deeper.
The key is learning to read the substrate and the plantNot all species require the same watering frequency or retain water equally. For example, to disprove the myths about cacti Understanding these differences helps: a Mediterranean shrub in the ground doesn't have the same needs as a tropical plant in a small pot. Furthermore, the time of year, sun exposure, wind, and soil texture (clay, sand, rich in organic matter) completely change the situation. Trying to apply a general rule like "water every day" is simply a recipe for disaster.
Irrigation should be based on observation, not anxiety.Inserting a finger into the soil, lifting the pot to feel its weight, observing whether the leaves droop at certain times and recover in the late afternoon… these are more reliable indicators than any rigid schedule. A good gardener is more like a neighbor who participates in the neighborhood meeting than a bureaucrat filling out forms: they listen, interpret, and adjust, instead of blindly following a protocol.
Furthermore, the role of periods of mild drought must be understood. In many species, some trees and shrubs flower or fruit better after a period of reduced watering, which acts as a signal to initiate key physiological processes. Just as in community projects, controlled stress can activate internal resources and strengthen the structure, provided it doesn't cross the line into irreversible damage.
Myth 2: “With chemical fertilizer every week you will have spectacular plants”
Another piece of advice that does more harm than good It's the tendency to overuse fast-release chemical fertilizers, convinced that "the more I give it, the better it will be." This short-sighted approach is reminiscent of neoliberal policies that promise rapid growth through debt: there might be an initial boost, but the hidden cost is enormous, and it ends up being paid by those least responsible. In the soil, the first to suffer are the microorganisms that maintain the substrate's true fertility.
The intensive use of soluble fertilizers It disrupts the balance of nutrients and salinizes the soil. The roots are subjected to an aggressive chemical environment that, over time, reduces their ability to absorb water and minerals. A dependency develops: if this "chemical dose" is no longer supplied, the plant suffers because the soil no longer functions as a living ecosystem but as a mere inert support. It's the same logic that leads many debtors to accumulate loans: without external funding, nothing can be sustained.
Many home gardeners rely on the packaging. where “explosive flowering” or “guaranteed growth” is promised, without reading the fine print about frequency and dosage. As happened with certain mortgage decrees that force the debtor to return even the subsidy received in case of foreclosure, there are toxic conditions camouflaged behind the glitter of the promise. In the garden, this toxicity translates into leaves burned by excess salts, imbalances between nitrogen, phosphorus, and potassium, and greater vulnerability to pests and diseases.
The alternative involves understanding land as a common good It must be managed with sustainability criteria, not with a focus on quick profits. Just as some self-managed housing groups advocate for a different way of building cities, one that is more supportive and less subject to financial capital, in gardening we can opt for organic fertilizers, compost, mulching, and crop rotations that nourish the soil at a pace compatible with the life it sustains.
Incorporate quality organic matter (mature compost, well-decomposed manure, shredded plant remains, eggshellsIt improves soil structure, increases its water retention capacity without becoming waterlogged, and fosters a diverse microbial community. These improvements don't appear overnight, just as a serious community project isn't evaluated by an advertising campaign, but by the results accumulated over years of quiet work.
It's also wise to be wary of miracle solutions. They promise to "resurrect" any plant with a simple product. Nothing replaces an honest diagnosis: some plants are severely damaged and will not recover, no matter how much fertilizer is applied. In such cases, the sensible thing to do is accept the loss, learn from what happened, and redesign the garden or orchard to prevent the same adverse conditions from recurring.
Finally, it is essential to adjust nutrient intake to the life cycle of each species. It makes no sense to fertilize heavily during winter dormancy or to indiscriminately apply nitrogen to plants already weakened by lack of light or water stress. It would be like forcing a sick person to work longer hours instead of addressing the underlying causes of their illness. Proper fertilization is strategic, modest, and closely tailored to the specific needs of each plant.
Myth 3: “Nature takes care of itself, there’s no need to plan anything”
Perhaps the most dangerous myth of all It's the kind of thinking that masquerades as absolute respect for nature to justify total inaction. You often hear, "I won't touch anything, let the garden be wild," as if simple neglect were synonymous with ecological balance. Just as in local politics, leaving everything to "market forces" creates unequal neighborhoods and belts of poverty, abandoning a space shaped by human activity without any planning rarely ends well.
Urban gardens and orchards are not virgin ecosystemsThey are usually built on land that is already degraded, contaminated, or heavily altered by construction. There are construction debris, compaction from heavy machinery, poorly managed water, and, in many cases, a long history of misguided decisions that have left their mark. To pretend that “nature will fix it” without minimal intervention equivalent to self-managed housing policies—that is, policies designed by those who live in the space—is to turn a blind eye to the material reality of the land.
A sustainable garden needs planning and participationJust like citizen study groups analyzing contemporary cities in Europe, Africa, and Latin America, gardeners must observe, engage with the surrounding environment, and design. They must study the orientation, the sun's movement, wind direction, rainwater runoff points, the proximity of large trees that compete for resources… All of this forms part of a diagnostic process without which any planting is merely wishful thinking.
Many cities have promoted "green self-build" projects Similar to cooperative housing initiatives, these projects involve neighbors organizing to transform abandoned lots into parks, rooftops into gardens, or neglected flowerbeds into small oases of biodiversity. These processes are neither spontaneous nor magical: they require bylaws, assemblies, shared responsibility, democratic control of funds, and a sustained effort that extends beyond the initial photo op.
In the home garden, this planning translates Choosing species adapted to the local climate, combining layers (trees, shrubs, perennials, ground cover) to create microclimates, establishing areas of shade and sun, and anticipating future growth to avoid space conflicts are all crucial. Letting everything grow unchecked can lead to veritable plant ghettos: invasive plants that crowd out weaker ones, such as certain self-seeding plantsPoorly positioned trees that damage structures or roots, fiercely competing for increasingly scarce water.
Neglect also opens the door to pests and health problems.An unpruned hedge accumulates dead wood, an ideal refuge for fungi and wood-boring insects; an unmaintained fountain becomes a breeding ground for mosquitoes; an unmown lawn encroaches on pathways and covers up interesting species that disappear due to lack of light. Just as power vacuums in municipalities are exploited by patronage networks or organized crime, management gaps in parks and gardens are filled by opportunistic organizations that are hardly committed to balance.
That doesn't mean falling into the opposite extreme. Instead of turning the garden into a military barracks, with every leaf controlled and every flower measured down to the millimeter, the obsession with absolute order is just as exhausting as neglect. The key is to find a middle ground, with clear but flexible rules, spaces for supervised freedom, and room for experimentation. In a vegetable garden, for example, you can leave a corner of wildflowers for pollinators without sacrificing the rational rotation of the main crops.
The participation of all members of the household It's also key. Just as neighborhood assemblies give a voice to women, young people, and traditionally silenced groups, in the garden it's important that children, the elderly, and people with disabilities can express their opinions and make suggestions. Sometimes, someone with limited mobility offers the best idea for making use of a passageway or installing a bench where before there was only a dead corner.
Towards a fairer, healthier and more livable garden
If there's one thing that the experiences of citizen organizations teach us Those who fight for decent housing, public services, or urban reforms understand that profound changes don't come from above or from a miracle cure: they are achieved little by little, combining knowledge, cooperation, and self-criticism. The same is true in gardening. The three major myths we've examined—watering excessively, fertilizing without restraint, and neglecting the space by relying on an abstract nature—are convenient because they seem like simple solutions to complex problems. But their convenience is deceptive.
To build a truly living and sustainable garden It means accepting that we don't have all the answers, that we're going to make mistakes, and that some plants will be lost along the way. In return, we gain something much more valuable: the opportunity to learn from every mistake, to adjust irrigation to what the soil truly needs, to nourish the land without mortgaging its future, to design spaces that more closely resemble who we are and who we want to be as a community than a shopping mall catalog.
In that process, the garden ceases to be a mere decoration and becomes a laboratory of citizenship, a small territory where one can practice that mixture of responsibility, solidarity and common sense that is so needed beyond the fence.
