Watering New Trees: Deep, Not Daily
The most common tree-loss cause after planting is shallow, frequent watering – the deep-root routine that establishes trees.
Direct answer: water deep and infrequent – fill the root zone 1-2 times per week in the first season, delivering water below grade via a deep root irrigator (RWT) or a bubbler basin (NP). Deep soaking drives roots downward; daily splashes keep roots at the surface.
Size the device to the tree: RWT-30 for shrubs and whips, RWT-49/68 for small trees, RWT-86 for mature specimens. On municipal projects, RWT tubes on a dedicated valve zone let the CA12 scheduler water street trees independently of turf.
How many liters does a new tree need?
It depends on species, soil and season – the SL soil-moisture sensor removes the guesswork by holding the root zone in the 25-45% moisture bands.
Bubbler or root irrigator for street trees?
Root irrigators – they cut evaporation and runoff to zero and keep the surface dry for pedestrians.
