Continuing my series on my progress toward transitioning my yard to a suburban savanna…..

This month I am focusing on water. My yard has a sprinkler system that was installed in the late 90s. We get it checked at the beginning of each season and replaced the controller last year so that it doesn’t come on if there was rain recently (prior that that we often manually turned if off earlier in the growing season when our area gets enough rain for plants to thrive).

This year I am watering as I have in years past since so many of the plants are new. Next year I will likely reduce either the duration or the frequency since the plants are native and should thrive without extra water. In subsequent years when most plants are well established, I might simply turn on the sprinklers manually…only when there are very long periods with no rainfall (i.e. in drought conditions).

The only plant that will likely need extra attention is an Kousa dogwood (planted by a previous owner) that is growing in full sun. Even with the watering I do now, it tends to get some dry/brown leaves in summers with high heat and little rain. It’s not a native so obviously is not honed to our Missouri climate! I might put a soaker hose in to specifically provide water to the roots of the tree….or plant some green native ground cover (something like golden ragwort on the north and south, Missouri evening primrose on the western side, violets on the eastern side) under the tree that will keep the soil cooler than the mulch that is currently there.

In a few years, if something on the sprinkler system breaks enough that it would required replacement – maybe I will decide I don’t need a sprinkler system often enough to warrant the expense!
