Green Giant Spacing

Discussion in 'Homeowner Helper Forum' started by ggscreen, Sep 5, 2018.

For GG 2 rows, what should be spacing between front and back row? Spacing between the trees?

  1. 3 or 5 ft for space between 1st and 2nd row?

  2. 6, 8, 10 or another amount for the space in between the GG?

    I’m looking for complete privacy and trying to get green giants as tall as possible. I have plenty of space for staggered 2 rows but I’ve read a wide range of advice on the spacing between the front and back row ( 3-5 ft) and space between trees (5-12ft). These ranges are too broad and I don’t want to randomly guess on a tree that will hopefully be in place for 30 years+. I really want to get this right and I’m okay with the front row overlapping with second row because one tree may grow thinner than another one and I don’t want any gaps. The goal is not to try to plant as few as possible; instead the goal is no gaps, healthy and strong root structure and preparing for the long term growth. Thank you in advance and I welcome all your thoughts and ideas!

    I would space the rows 3’ apart and space the trees 8’ apart alternately in each row. This gives you 5’ spacing between plants. This should give you complete privacy in a couple years.

    Planting them closer together will cause the lower branches to die out later in their life. Farther apart will take longer to achieve privacy.

    Thanks!

    I just planted the GG and they look awesome! I have 7 GG that are around 6-7 feet tall. I did have a few questions because I want these GG to grow healthy and last:

    1) What's the best way to water GG so you get deep roots? My local nursery said I should water 4 times a week for 10-15minutes (90+ degree heat here), but I'm worried the watering is happening too fast and roots don't have enough time to absorb the water causing the roots to grow near ground level, instead of deep into the soil. I really welcome your thoughts on how to do this properly.

    2) Should I water the plants with a "dripper" hose or just use a sprinkler on low? My local nursery discourage a dripper hose because they worry about the holes plugging so I've been using a sprinkler on low. However, using a sprinkler is fairly inefficient way to water because I'm constantly moving the hoses to water "360" degrees around the GG.

    3) Water: For watering, should I be watering just by the tree stem or should I be watering the stem + a 4-6 inches circumference around the GG?

    4) Mulch: how much mulch should I be using and what's the best kind (hardwood, cedar or something else)? I know to keep the mulch away from the stem and branches, but I wasn't sure how far to extend the mulch and which kind to get.
