Self-watering planters have become a popular choice for busy plant parents and those prone to forgetting watering day or who are an over waterer. These clever containers offer a reservoir of water that slowly hydrates your plants, promising a low-maintenance approach to keeping your indoor jungle thriving. But are they all sunshine and rainbows? Let's delve into the pros and cons of self-watering planters and explore the different growing mediums you can use within them.
Pros of Self-Watering Planters:
- Reduced Risk of Overwatering: One of the biggest benefits is the elimination of overwatering, a common plant killer. The reservoir provides a consistent water source, preventing the roots from sitting in soggy soil.
- Reduced Maintenance: Self-watering planters extend the time between watering sessions, making them ideal for forgetful plant parents or those who travel frequently.
- Consistent Moisture: By offering a constant source of water, self-watering planters can help maintain consistent moisture levels, which is beneficial for many plants.
- Peace of Mind: Going on vacation? No worries! Self-watering planters provide peace of mind knowing your plants will stay hydrated while you're away.
Cons of Self-Watering Planters:
- Not Suitable for All Plants: Plants with specific watering needs, like cacti or succulents that prefer to dry out completely between waterings, may not thrive in self-watering planters.
- Risk of Underwatering: Although less common, underwatering can occur if the reservoir isn't filled properly or the wicking system malfunctions.
- Monitoring Challenges: Since the soil moisture isn't readily visible, it can be difficult to assess your plant's needs and adjust watering accordingly.
- Maintenance Needs: While low-maintenance, self-watering planters do require occasional cleaning to prevent mineral.
Growing Mediums for Self-Watering Planters:
While traditional potting mix can be used in self-watering planters, other options offer potential benefits:
- LECA (Lightweight Expanded Clay Aggregate): These lightweight clay pebbles have recently gained popularity in the indoor plant world. It provides excellent drainage and aeration while still retaining some moisture. They are perfect for plants that prefer not to sit in wet soil for extended periods. This set-up is known as a semi-hydro set-up / semi-hydro plant.
- Well-Draining Soil: You can use your traditional soil, just make sure it’s chunky and well-draining. Well-draining soil offers good drainage and moisture retention. It's a good choice for a variety of plants.
- Semi-Hydroponic Growing Media: For a truly low-maintenance approach, consider specialised semi-hydroponic mediums designed for self-watering planters, such as PON-N-LECA Mix. This mix is the perfect balance between PON and LECA. It contains the PON Mix for stability as well as LECA for aeration. This mix often requires the use of a nutrient solution instead of traditional fertiliser, such as GT Foliage Focus.
The Verdict?
Self-watering planters can be a fantastic option for busy plant enthusiasts or those who struggle with maintaining consistent watering. However, it's crucial to choose the right planter size and growing medium for your specific plant's needs. Remember, even with self-watering planters, observing your plants' health and adjusting the watering schedule as needed is key to their success.
So, are self-watering planters right for you? Consider your lifestyle, plant choices, and willingness to learn about different growing mediums before making the switch. Preferably starting with a small, rooted cutting, such as a Devils Ivy Pothos.
