You can improve drainage in pots by using containers with holes, placing a drainage layer at the bottom, choosing light and porous substrates, and adjusting your watering schedule. This will prevent waterlogging, root rot, and reduce plant loss.<\/p>\n
Many people think the plant died suddenly, but in reality it's stagnant water in the pot. Small adjustments when assembling the pot make all the difference. Let's see step by step how to achieve almost perfect drainage without spending a lot of money.<\/p>\n
Poor drainage leaves water trapped in the pot, preventing the roots from breathing. This problem causes soft roots and diseases, leaving the plants weak.<\/p>\n
According to research by gardening associations in 2022, overwatering is one of the main causes of death for potted plants. Therefore, adjusting drainage prevents a lot of headaches.<\/p>\n
Take the case of a resident of S\u00e3o Paulo who leaves flowerpots on his balcony. A week of heavy rain in the summer turned the soil into mud, and the leaves began to yellow. This happens precisely because of a lack of drainage.<\/p>\n
The roots become too submerged, suffocated by lack of oxygen, and begin to rot. This harms the entire plant, which stops absorbing nutrients.<\/p>\n
With waterlogged roots, you'll notice a bad smell coming from the pot and drooping leaves. This situation worsens if you don't intervene quickly.<\/p>\n
Check if the surface of the substrate remains wet for days or forms a crust. When touched, the soil sticks to your fingers like a paste.<\/p>\n
Wilted or yellowing leaves are clear signs. If you suspect this, read more about it. Are My Plants Wilting? See How to Help Them Quickly<\/a> In the second paragraph, to better identify the causes of wilting.<\/p>\n Pots with drainage holes facilitate watering, but many decorative pots don't have them. Even so, you can adapt them without spending extra money.<\/p>\n In apartments where aesthetics matter, avoid using a toilet without a drainage hole. This option helps prevent future problems.<\/p>\nPots with or without drainage holes: what to do in each case?<\/h2>\n

| Ceramic shards<\/td>\n | Recycling is free, that's great.<\/td>\n | It may retain an odor.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\nExpanded clay, gravel, styrofoam, and broken glass: pros and cons.<\/h3>\nExpanded clay is popular because it is lightweight and does not compact. Crushed stone helps with stability, but it weighs more.<\/p>\n Recycled styrofoam is useful for not overloading the balcony. Broken shards of a bowl fit well at the bottom; just wash them first.<\/p>\n How to use geotextile fabric, non-woven fabric, or felt as a filter.<\/h3>\nPlace geotextile fabric over the drainage layer to prevent the substrate from falling into the holes. Non-woven fabric also filters without clogging.<\/p>\n Felt is thicker, ideal for large pots. These materials prevent soil from getting into the saucer.<\/p>\n Better draining substrates: how to prepare the right mixture<\/h2>\nLightweight and porous substrates, such as sand and perlite, make a difference. Mix regular soil with these ingredients for better drainage.<\/p>\n For green plants, coarse sand is preferable. In cases of affected roots, changing the substrate helps with recovery.<\/p>\n In Curitiba, succulents thrive in sand and perlite. Salvador uses charred rice husks in its gardens.<\/p>\n |
