Essential care for large houseplants: complete guide
The success of caring for large houseplants, such as monsteras, ficus, kentias, palms, philodendrons, and others, depends on multiple factors. These species often require More attention in certain aspects due to their size, growth capacity, and specific needs. Below, we explore each of these factors in detail, incorporating advanced tips and essential tricks to make your plants the centerpieces of your home.
Selecting the most suitable indoor plant
Before making any purchase, it is essential to choose the large indoor plant that best suits the conditions of your home. Some species, such as the Monstera delicious, the ficus lyrata or Lucky bamboo, are more durable and versatile, ideal for beginners. Others, such as the Kentia (Howea forsteriana) and areca palm, require brighter environments and somewhat more specific care.
- Evaluate the natural light in the room where you are going to place the plant.
- Considers the available space, since an adult specimen can occupy several square meters.
- Keep in mind the ease of maintenance: Some species tolerate lack of irrigation or temperature variation better.
- To choose the pot, remember that roots and drainage are critical for good development.
Location and temperature: a key factor for your health
La location This is one of the most important points. Although we're talking about "indoor" plants, each species has specific requirements in terms of light and temperature:
- Intense indirect lightMost large indoor plants, such as ficus and monstera, require abundant, but not direct, light. Place them near large windows with sheer curtains to prevent the sun from burning their leaves.
- Homogeneous light throughout the plantDue to its size, only part of the plant may receive adequate light. Rotate the pot periodically to ensure the entire plant has access to light and prevent uneven growth.
- TemperatureMaintain a stable temperature, avoiding sudden changes. Large indoor plants generally prefer temperatures between 18 and 25 degrees Celsius, away from heat sources such as radiators or cold drafts from windows and doors.
- Beware of drafts: Avoid placing them in places exposed to currents that can dehydrate them and weaken their immune system.
Substrate and pot: the basis for success
A good substrate is the foundation on which all healthy plants rest. In large plants, this factor becomes even more important due to root volume and absorption capacity:
- Aerated and well-drained substrate: Mix universal substrate with perlite, coconut fiber, pine bark or volcanic gravel to avoid compaction and promote aeration.
- Additional drainage: It is advisable to place a layer of pebbles, gravel or expanded clay at the bottom of the pot to prevent waterlogging that can rot the roots.
- Pots with holes: Always use pots with drainage holes to ensure excess water drains away.
- Tutors and supportsIf the plant is very tall, use stakes or structures to ensure its stability, especially after transplanting or when exposed to drafts.
- Renew the substrate periodically: Every two or three years it is advisable to renew part of the substrate and increase the size of the pot if the roots have occupied all the space.
Watering: How to properly water large indoor plants
One of the most common mistakes is associating size with water consumption. Although they need more water than a small child, too much can be fatal. We explain. How to properly water a large indoor plant:
- Moderate and spaced wateringIndoors, evaporation is lower. Always check the substrate moisture before watering by inserting a finger or using a toothpick.
- Uptake/bottom irrigation: Place the water in a saucer under the pot and let it absorb for a few minutes, avoiding flooding the top of the substrate and promoting stronger root development.
- Adapt the frequency Depending on the season: In spring and summer, water more frequently (once or twice a week). In autumn and winter, reduce watering to every ten or fifteen days, always checking the actual humidity of the substrate.
- Adjusts the pH of the waterSome indoor plants struggle with tap water due to its high salt content or alkaline pH. You can use filtered water, rainwater, or add a few drops of vinegar or lemon juice to acidify it.
- Watch for signs of excess or lack of water: Yellow, soft or drooping leaves usually indicate watering problems.
Environmental humidity and its importance
Many large indoor plants, especially those of tropical origin, They need environmental humidity To maintain the splendor of its leaves and prevent them from drying out or turning brown at the edges:
- Keep relative humidity between 40 and 70%, using humidifiers, trays with water near the pot, or spraying warm water on the leaves (as long as the species tolerates it).
- Spray sparingly, avoiding excessive wetting to prevent the appearance of fungi.
- Groups several plants: This creates a more humid microclimate that is beneficial for all.
- Measures humidity with a hygrometer to adjust care and ventilate if there is excessive condensation.
Fertilizer: nutrients for healthy and vigorous growth
Indoors, plants cannot obtain nutrients from their natural environment, so fertilization is a fundamental aspect:
- Fertilize with specific products For green or indoor plants, preferably liquids diluted in the irrigation water. Do this during the period of active growth (spring and summer).
- Low and regular doses: It is better to fertilize lightly every two or three weeks than to fertilize heavily less frequently.
- Natural fertilizers: You can supplement your diet with dried coffee grounds (nitrogen content), tea infusions, or crushed eggshells (calcium content).
- Fertilize with organic compost in spring to stimulate faster and more robust growth.
Pruning, cleaning, and maintenance: aesthetics and health for your plants
La regular pruning and cleaning They are essential for your plant to look beautiful and have a balanced development:
- Training and sanitation pruning: Remove dry, wilted, or damaged branches, leaves, flowers, or stems. This prevents the spread of diseases and pests and encourages new growth.
- Control of size and shapeIf the plant invades the space of other plants or grows in a disorderly manner, trim the longest or uncontrolled branches to guide its growth and maintain an aesthetic shape.
- Leaf cleaningAccumulated dust reduces photosynthesis capacity and impairs the plant's health. Clean large leaves with a damp cloth, and small leaves by spraying them with warm water and shaking gently.
- Pot rotation: For symmetrical growth, rotate the pot from time to time.
Prevention and control of pests and diseases
The Large indoor plants can hide pests and diseases in its density of leaves and branches. Frequent observation is key to acting quickly:
- regular inspection: Check the upper and lower sides of the leaves for insects, spider webs (red spider), stains, deformations or sticky spots (aphids, mealybugs, whiteflies).
- Green products: Use potassium soap, vegetable oils or organic insecticides for preventative or eliminative treatments.
- Improves drainage and prevents excess moisture to prevent fungus and rot.
- Remove affected parts immediately and dispose of them outside the home.
Transplants: When and How to Perform Them Correctly
Large indoor plants They require transplants from time to time To renew the substrate and provide more space for the roots:
- Transplant preferably in early spring., before the period of vigorous growth.
- Choose a pot 20% larger than the previous one and use fresh, quality substrate, ensuring good drainage at the base.
- Avoid damaging the roots during the process and maintain moderate watering after transplanting to facilitate adaptation.
Common mistakes and solutions for caring for large indoor plants
Many problems arise from easy mistakes to avoid:
- Stagnant water at the base: Always empty the excess water from the saucer after watering.
- Inappropriate location: Neither too much direct sun nor shady or drafty spaces.

- Do not clean the dust: prevents photosynthesis and can attract pests.
- Lack of plant rotation: It can grow crooked or with sparse areas.
