Irrigation in Indoor Plants: [Basic and Complete Guide]

Do you have indoor plants in your house and you are not sure how they should be watered?

Do not worry. You have reached the right article.

Each type will have its specific conditions in this area, so you have to know well to   the species before subjecting it to a watering schedule.

In any case, specialists in the field advise that it be once a week and with a watering can or sprinkler to regulate the amount.

In addition, we must consider the fact that indoor plants are not directly subjected to the changes of the seasons like those we have in the garden.

At this point we must also refer to the importance of having a good drainage .

To do this, you have to know how to choose the pots well , which have holes in the bottom of the container.

And use an aerated substrate that allows the passage of the liquid.

Important points when watering your indoor plants

  1. Keep the plants in pots with drainage holes to avoid waterlogging.
  2. Because they are not directly exposed to sunlight , the evaporation process of water through the leaves is slower. This means that the irrigation system must be evaluated very carefully to avoid drowning them.Water most plants every 2-4 days (or as needed) in spring and summer to keep compost moist (not watery).
  3. Water desert cacti and succulents less often (only when the top of the compost looks dry).
  4. Reduce the frequency of watering in winter , when plant growth is slower and temperatures are lower.
  5. Remove excess water from the sleeves of the pots and saucers to avoid too soggy compost.
  6. Avoid getting water on the leaves and stems of plants with soft, furry foliage, or on succulents and cacti.
  7. Check if your plant prefers rainwater or distilled water instead of what comes directly from the tap.

When to water indoor plants?

Most indoor plants prefer moist compost in spring and summer when they are growing, but be careful not to over water; soggy and waterlogged compost causes disease and can be fatal; with a little dryness you could fix the problem.

To avoid the wet compost, keep your plants in pots with drainage holes in the bottom so that any excess water can drain and discard any surplus remaining in the pot the plant or in the saucer, about an after hour water.

How to water indoor plants?

Watering from above

Pour in water from above if your plant shows good-looking, lively foliage; most tropical plants and ferns are included in this category.

Make sure the compost is also soggy or you risk watering the leaves without moisture reaching the roots.

Irrigate the land directly

Put your plant in a pot with drainage holes in a tray of water about 2 cm deep.

Leave it for 20 minutes, then remove it and drain it. Use this method for plants that don’t like wet leaves or stems, such as African violets , or if foliage is covering compost.

Fogging of leaves and aerial roots

Some plants absorb moisture through their aerial leaves and roots. Some examples that we can find are orchids , Swiss cheese plants and areca palms.

Mist the leaves and roots regularly, but also water the compost to keep them healthy.

Soaking the plants in air

Air plants are best soaked in a tray of rainwater or distilled water for an hour once a week.

After soaking them, let them drain and make sure they are completely dry after 4 hours to avoid rotting.
