Should Begonias Be Watered From The Bottom?

Introduction to Bottom Watering Begonias

Begonias are a popular choice for indoor gardeners due to their vibrant colors and low maintenance requirements, however proper watering is essential for healthy begonia plants. One way to ensure that begonias receive the right amount of water is by bottom watering or ‘soak and dry’ method, which can be beneficial for many reasons and should be considered when caring for begonias indoors.

Why Begonia is a Popular Choice for Indoor Gardening

Begonias are a favorite among indoor gardeners due to their bright colors, ease of care, and ability to tolerate indoor environments better than many other plants. They’re also relatively inexpensive, making them accessible even on a tight budget! It’s important to remember that with any houseplant, proper care is essential in order to keep it healthy and looking its best, including proper watering techniques such as bottom watering begonias.

What is Bottom Watering?

Bottom watering (or ‘soak and dry’) refers to the method of watering in which the plant is placed in a tray of water and allowed to absorb it through the drainage holes at the bottom of the pot or container without getting the leaves wet. This method ensures that the soil has enough moisture without exposing the foliage to excess water that could lead to fungal problems or rot, common issues with begonias grown indoors.

Benefits of Bottom Watering

The biggest benefit of bottom watering begonias is that it prevents fungal problems and rot because it avoids wetting the leaves which can cause these issues in indoor plants due to lack of air circulation compared to outdoor plants.

Soil moisture can also be more easily monitored when using this method as it allows you to see how much water has been absorbed into the soil before adding more if necessary. Additionally, bottom watering helps reduce mess and waste since any excess water will be absorbed into the soil rather than running off onto counters or floors like with traditional top-watering methods.

How To Bottom Water Begonias

To bottom water your begonia, simply fill a plant tray or cache pot with lukewarm water until it reaches just below the drainage holes in the pot and allow your plant time to absorb it through those holes into its soil until no more will be taken up (this should take about 10-15 minutes).

If you don’t have access to a tray or cache pot, you can also use an overturned saucer placed under your plant’s pot before filling it with water up until just below its drainage holes – this will act as makeshift tray or cache pot!

Make sure you empty out any remaining water after your plant has finished taking up what it needs, if left sitting in excess moisture for too long, your begonia may become susceptible to root rot or other fungal issues so don’t forget this important step!

Potential Problems Of Bottom Watering

Though bottom watering can help prevent fungal problems and rot when done correctly, there are still some potential issues associated with this method such as overwatering if too much water is used or if not enough time is given between each watering session (which should be at least once per week).

Furthermore, if your plant isn’t draining properly due either inadequate drainage holes or clogged ones then this could cause standing water in its base which could lead to root rot – an issue that could ultimately kill your plant if left untreated!

Tips For Avoiding Potential Problems

In order to avoid any potential problems associated with bottom-watering your begonia, here are a few helpful tips:

  • Use lukewarm water instead of cold, cold temperatures could shock your plant’s roots which could lead them dying off over time resulting in weakened growth or even death!
  • Always make sure there are adequate drainage holes at the base of your container so excess moisture can escape – otherwise there’s a chance root rot may occur from standing water,
  • Don’t overfill your tray/cache pot, leave about an inch between where you fill up and where the drainage holes begin,
  • Allow plenty of time between each session (at least one week) so that soil has time to fully dry out before being watered again,
  • Don’t forget to empty out any remaining water after each session – standing water can still cause root rot even after only one session!

Alternatives To Bottom Watering

If you don’t want to use bottom-watering as your primary method then there are other alternatives you can use such as top-watering (where you pour directly onto soil surface) or mist-watering (where you spray mist onto surface).

Both methods have their own benefits depending on what type of environment your begonias are growing in but generally speaking mist-watering tends work best indoors due its low mess potential while top-watering tends work better outdoors due its ability keep foliage dry which reduces risk for fungal problems/rot from excessive moisture exposure from both environment & irrigation alike .

Best Practices For Watering Begonia

No matter what type of irrigation method you choose when caring for your begonias indoors (i.e., top-watering vs bottom-water vs mist-water), here are some general tips & best practices:

  • Make sure not too over/underwater – all plants need proper hydration but too much/too little can quickly damage them,
  • Test soil moisture levels regularly so that you know when it’s time for another drink,
  • Avoid wetting leaves whenever possible as this increases risk fungal problems & rot,
  • Ensure adequate drainage so that any excess moisture doesn’t stay pooled around roots,
  • Check regularly for signs disease/pest infestations such as wilting leaves & discoloration,
  • Adjust irrigation frequency according season/environmental conditions,
  • Consider using an automated system such as drip irrigation ensure optimal hydration levels all times – this especially useful if away from home frequently!


Bottom watering begs is an effective way ensure proper hydration while also preventing fungal problems & rot common among houseplants grown indoors due lack air circulation compared outdoor plants – however there still potential pitfalls associated with this technique so always practice caution when doing so!

There are also other alternatives available those who don’t want use bottom-water such mist-water & top-water but regardless what type irrigation method choose make sure always test soil moisture levels regularly adjust frequency according season/environmental conditions while avoiding wetting leaves whenever possible order keep healthy happy!
