<s>[INST] When selecting a poplar tree for landscaping, what are important factors when planting it and in post-planting care.
When selecting the right poplar tree, the following guidelines must be kept in mind. 
Planting Location trees prefer location with full sun and well-draining soil. Also avoid planting over power lines or where circumferences can encroach on nearby structures. Consider latitude and sites with spacing.
1. Full sun – a location that receives at least 6 hours of direct sunlight a day.
2. Drainage -  ensure the soil does not remain water logged for any extended period.
3. Avoid planting over power lines as the matured height may cause problems.
4. Avoid planting too close to structures to avoid encroachment of the canopy area.
5. Select a tree that is suitable to your site latitude and uses suitable planting space.
 
Planting:

- dig the planting hole two times as wide as root ball and just as deep as well.
- Gently remove the burlap and any string from the root zone to prevent constricting. Maximize and un-tangle roots around where roots touch butting perimeter of out sides, straighten bent roots to a out face.
- Planting temperature: Ideal planting temperatures for poplar trees are from fall (August- October) or during a cooler period (winter). Temperate months and hot or dry weather is to be executed with great caution.

Post Planting Care:

1. Watering – moderate watering during the first year avoids over watering.  Watering once or twice a week for the first year.
2. Mulching – create a 1-2 inch thick band of wood chips and maintain in a 12-18 inch radius around the trunk of tree to help in fertilization and moisture retention and control weeds from growing near roots.
3. Support – during the first establishment years, provide tree with staking only with loosely tied straps and wires it must be loose enough to allow an inch of tree sway movement.
4. Fertilization – Follow NPK ratio for this North American species’ – of 10-10-10. There is no strict limit on organic versus chemical-based compost, a moderate application is recommended.
