What is a self watering planter?

If you are a busy person who doesn’t stay at home for a long time. Or you don’t have anyone to water your plants regularly then you obviously need self-watering planters. If you don’t want your plants to dry out or they are at a difficult place like a balcony then you must purchase a self-watering planter. You must be thinking of reading the name “self-watering planter” that it means an automatic watering system. But you wrong because such planters are made to become a consistent source of moisture to the growing plants. So you not required to water them daily. Although every self-watering planter looks different in shape and size the main technique is the same for all.

What are the parts and common features of a water planter?

Every planter works the same, the water is directly poured into a reservoir and then sent to the planting container above it. A typical self-watering planter consists of:

  • Water reservoir

The top of the planter consists of a mix and plants and a water reservoir under it. There are a lot of reservoirs that have different sizes of each container. The reservoirs range from 1 gallon to 5 gallons according to planters. But before choosing any planter always look at the size of the reservoir. It must be proportional to the size of the planter so you don’t have to fill the reservoir every day. The reservoir must be enough to provide adequate moisture to the plant for a few days.

  • Planting container
  • Wicking mechanism
  • Fill tube

Pour water directly into the reservoir by an opening known as a fill tube. The fill tube can be found at anyplace according to the company’s manufacturing. You will find some tubes with caps made to avoid the pests and debris entering the reservoir. Fill tubes are attached directly to the reservoir so you can pour the water directly into it.

  • Overflow spout

The planters come with an overflow mechanism to drain out the water from the reservoir when it’s full. It’s actually very important for the water to drain out so the plants don’t sit in too much water hence they will rot quickly.

  • Water level indicator

Some renowned companies manufacture planters with a water level indicator. The indicator keeps you informed about the water in the reservoir. It’s a great system to give you a great idea about the water in the reservoir.

  • Drainage hole with plug

The planters come with a drainage hole and plug so you can drain the water at the end of the season. It’s better to drain it before winters so the water in the reservoir doesn’t freeze during winters.

How do self watering planters work?

No matter how many different planters in the world exist, any planter works in two ways only. Capillary action is the basic method of sending water from the reservoir to the plant.

  1. The common method known as the “wick”.The wick installed in the reservoir from one end and the other end in the potting mix. The wick is actually a capillary mat, an absorbent tube-shaped plug, or a thick string. So the wick is actually sucking water from the reservoir and sending it to the potting mix.
  2. The other system is totally different from wick where the planting system sits in the water reservoir. The potting mix that sits in the water sends the water above to the plant through capillary action. This design is also very common.
  3. The third design is very uncommon and rare. This Papular a self-watering system. Here the planter designed in a way that the reservoir and the planting mix will never meet each other. This method is based on evaporation. The water from the reservoir evaporates in the summers to moisten soil at the bottom of the planter. Then the water from the bottom of the planters spread throughout the soil.However, this design works in summers only so rejected by many users.


Why are the self watering planters helpful?

  • Regular moisture and less frequent watering

The biggest benefit of a self-watering plant the regular moisture given to your plant. There is no need to water the plants with your hand and even if you are forgetful. Especially during summers, the plants need to be watered twice. People don’t even have time to water their plants during job or work. On the other hand, a self-watering plant will work for a week.

  • Use of water efficiently

People often waste a lot of water while watering their plants. The water reservoir ensures that the water use efficiently and effectively. Rather than evaporating directly into the air, the water sent from the bottom absorbs in the soil only. Even when you water plants through a spray a lot of waterfalls on the ground without benefiting the plant.

  • Avoids plants diseases

If you grow vegetables like tomatoes or phlox in the plant, they are often prone to get fungal diseases when the leaf remains wet. So the self-watering planter cancels out such issues by sending the water from the bottom. Grow your healthy vegetables through this method.

Note that you should not plant cactus and succulents in self watering planters because they don’t grow well in moist conditions.
