In depth about the selfwatering pots and boxes

You know them or you may have seen them in a store - selfwatering flower boxes or pots.

The name is obviously a little misleading. The box or pot water the flower but they will nevel fill by themselves (perhaps the producers may surprise us again later). Even so everybody can imagine how these selfwatering units may work and what their advantages are.

They represent a trend of our modern times. Do you have little time to do the watering twice a day during a hot summer? Does it strain you to carry full watering cans? Do you grow flowers in your holiday home where you can only get to at the weekends? If so then this solution is just for you. On our market there is a relatively large number of manufacturers which make products for growing plants using the selfwatering system, therefore the choice is wide. Here we give you a few pieces of advice how to orientate yourself in this area. Unfortunately not all such products meet our demands and not all of them work correctly.

In these vessels we can grow a wide range of plants such as room and balcony plants, summer annual and perennial flowers, scrub evergreen and coniferous species, small fruits, vegetables & hellip; only xerophilous and succulent plants are not suitable for growing in this type of units.

For the plants to be prospering properly, they have to have enough space for their root system. This si why you should choose vessels with bigger space for substrate. Select substrate which is coarser, lumpy, unsettled and which will allow air access to the roots. In the bottom part there is a space for a water reservoir. In a flower box of 60 cm in length you ideally need a water reservoir with 3 to 3,5 litre volume. In my own experience I can confirm that even on the hottest of summer days it suffices to top up the water reservoir once a week. The most important thing here is for the drainage opening to be placed so that the water level will never reach the substrate. Particularly if your flowers are not under the roof, exposed to rain, the surplus water simply must drain freely for the substrate not to decay.

This time even the aesthetic aspect may not necessarily be neglected as these boxes and pots are available in diverse color variations - white, pink, anthracite, pea to mention just a few.

So we have brought the plants, the selfwatering vessel and the substrate home. The planting procedure will be the same as with classical boxes. With the selfwatering ones you just check the wicks are in place. In the case the vessel has no wicks (indeed, it is not necessary) but has rising shafts, we will push the substrate into those shafts and then carry on like with any other box or pot. Fill the prepared vessel with the substrate up to one third of its volume. You can add a long acting fertilizer into this layer. Add more substrate so that it reaches two thirds of the vessel´s volume. Remove the plants from the transport pot and put them, just with the root ball, into the vessel. Then pour the substrate sufficiently around the plant and push it down lightly.

Freshly planted vessels to be watered initially only from the top.. If you have planted into the vessel large established plants, further watering will be carried out only be topping up the water reservoire. If we have young, small plants we carry on watering them from above for another 2-3 weeks and then start topping up the water reservoirs only. It is possible to add a fertilizer into the reservoir water, only use less contcentration solution.

Perhaps I have helped you to choose the correct vessel and contributed with some advice to successful plant-growing. I wish you a great deal of growing success!
