When you receive your staff cuttings, place them in a bucket of water for a day and then plant them after that.
If you are not ready to plant them, they can sit in water for a while. So place them somewhere cool, so they aren't trying to grow, but stay in a suspended state.
When planting your fast growing willow/poplar staff cuttings, make sure you plant them how they originally grew and not upside down. Place them in a hole that is a foot deep and give them a good soaking after planting them. If the ground is moist and soft enough, then you may not have to dig a hole and can directly push the staff cuttings in the ground (If you are picking up the bigger stake cuttings, those larger cuttings can be planted 2 feet deep).
One of the most beneficial things you can do is put a deep mulch layer around your newly planted fast growing cuttings, which helps with weed control and conserving moisture.
Make sure there is no sod or weeds growing within at least a 3' circle around them. If competing plants are not controlled, your tree growth will suffer and not live up to its potential of very fast growth rates.
Depending on the amount of rainfall and type of soil, a general guideline is to water these quick growing trees a couple times a week in their first year.
If your soil is average or below average fertility, you can also start fertilizing these fast growing trees a couple times their first summer, so they grow even faster.
By fall, your trees can be 10’ or more, already starting to serve their purpose in your landscape!
