You decide to do a couple pots. You know we need the soil and pots and plants. As our excitement about our project escalates, do we think about how to water them once they are in place?
In many climates, water is not often an issue. In cities like Seattle where there are 340 days of rain, potted gardens only need occasional supplemental water. However, as our climates continue to change with more and more areas experiencing drought conditions, we do need to consider how we are going to get the water to our containers.
You might be thinking to just use a watering can or a hose or possibly your existing or new irrigation system. Now I am not going to get into irrigating your pots in this post. That is a much larger subject than I am willing to tackle today. But I will leave you with the knowledge that 90% of the time when using irrigation, you need a dedicated valve and line to water pots correctly.
You might also have recently seen olla’s or glass balls that distribute water as the soil dries. I don’t have much personal experience with these. Having lived in the middle desert for 20 years I am somewhat leery of possible solutions where I cannot be sure that the water or moisture will be distributed throughout the full body of soil. I understand that this method is based on old ways of ‘the early days’ of gardening for food.
Let’s move back to the original topic of when it is best to hand water.
Cacti and Succulents
When you are potting up cactus and other succulents, hand watering is definitely the way to go. The frequency of water needed depends on the specific plant, the size of the pot and the amount of sun it receives every day. A basic guide is to water cacti and succulents monthly during the cooler seasons and bi-weekly in hot months. It is best to err on too little water, not over-watering.
For ornamental shrubs, trees, vegetables, herbs and flowers, I recommend hose watering rather than using a bucket or watering can. A hose with a good nozzle can provide a rain shower that is not only gentle in its application but thorough in distributing water to the entire soil bed.
A hose nozzle also provides a jet spray which will improve plant health when used daily during hot spells to aerate the plant and send off any pests that are lurking in the cool shade of the leaves. The mist setting on the nozzle will provide cooling respite for hot afternoons when the soil itself has not dried out enough to need to water.
