Green Giant Thuja- Is it True how fast it grows???
Comments (99)I planted 50 leyland's 3 years ago. They were in the 5 gallon buckets, about a foot tall each. Now they are 12 to 14 feet tall. Not one has died, gotten cancer or been toppled. I live in Northwest Georgia. These trees have seen the most extreme weather our area has seen in years. Let me give some unsolicited advice, with all due respect. 1. Whether they are green giant or leyland or arbovitae of any kind: Make sure you know your soil, make sure you know your frost level, and make sure you PLANT AND WATER AND FERTILIZE them appropriately. If you don't have time to manage them, then don't plant them. 2. Plant them far away from structures you don't want them to grow into. i.e: fences, buildings, septic tanks, neighbors who hate their shade etc. 3. plant them double their pot width, ONLY to the top of the pot you bought them with and with 1/2 native soil and the other half conducive to your local weather and environment. Be prepared to tie them off with rope that have maybe some cut pieces of garden hose around the rope to keep them from choking and which will help keep them level in high wind times if you are in a high wind area. 4. Applying water and appropriate nutrients is huge, but easy. GG's and Leyland demand alot of water if on a slope with hard clay or dense soil. Down south if you are in red clay, then water them morning and night for the first month or two. If you are up north or in moist soil, once a week watering with any spronkler system is going to be ok, just dont overwater at night, stick to early mornings. I applied 10/10/10 in a circle about 1 foot out from the tree bole in early spring, and then again early summer, because my red clay is very acidic, hence the 10/10/10. Nice basic nutrients. 5. Don't flip out about the cancer issues that you might tend to google; you are planting a long term resource for shade and beauty and perhaps privacy, so pay attention to your trees....daily. If the branches are browning on the outside but green on the inside, that ok, it's just growth. If you see a ring around the trunk, then do some research, I won't go into detail here. Just watch your trees, and remember, if you are planting in a row or around fences/property, your soil may be very different from one side to the other. The pic below is a recent one of my Leyland's after 3 years. They started out at about a foot. This is in PACKED Georgia red clay with lots of rocks. You may experience some growtg difference, but if they look healthy, they are healthy. I must say: Your initial soil preparation is huge. Plant them well. The GG's and Leyland's have a tap root that if given proper care, will grow deep and delve for nutrients. Out of 50 planted not one has died or had a problem. I am not a tree doctor nor do I play one on TV. I am...a lover of oxygen....See MoreThuja Green Giant Questions
Comments (2)My neighbor has three 2 ft over the property line. After about 15 years they are about 20 ft tall, 10 ft at the bottom, must have been planted with a spacing of 13 ft, because there is now a gap of 3 ft between them. The top seems to be not sharp, but rather plumb. It sounds like it would take them a long time to block that tall house. Perhaps after another 10 years they would be 35-40 ft tall and 20 ft wide. Branches seem to be weak, lost some last year due to ice. 6-8ft tall trees will probably have a good size root ball, I would assess their weight at the nursery and see if I can lift them, then it depends on transportation, i.e. how tough to get it in/out of a car trunk....See Morethuja green giant spacing
Comments (7)Hi greyhnds, Spacing should be 6' in my opinon. Here's some photos (of remember) trees that grow a minimum of 3 feet per year in the US when established. Basically in 5-7 years with trees being planted at a heigth of 1 foot or thereabouts, you'll have a tree(s) that becomes easily 15 feet tall x easily 5-6 feet wide (hence the nurseryies 6' recommendation)... and you have to remember that's just 5-7 years of this trees lifespan; "which ain't 'Jack'" if you think about it. 6' is perfect, believe me. 5' is too close. Here's some photos for ya from the US National Arboretum in Washington, D.C. taken the first week of May 2006. Single specimen in The Gotelli Conifer Colllection: (2) of 'Green Giant' as a screen planting: As to the fence, I'd go farther than 3 feet - the more the better. This is going to be a huge - huge specimen in as early as 20 years, therefore space them as comfortably as you can 'in your own space' without encroaching on your own property, i.e.' If I (myself) had the room, I'd go eight feet - but guage your own circumstance and do what you can. Take care, Dax P.s. There's another thread on 'Arbs' currently and I listed again, information about this hybrid as well as another Arborvitae called 'Hetz Wintergreen' and where both can be bought right now for pretty cheap....See MoreThuja Green Giant as a 6' hedge?
Comments (19)There's no way on this plantent, where you live, that Holmstrup will winter burn. Some idiot wrote that. Snow loads, nah, that's wrong too. That's a fine cultivar for what you're doing. Perfect for your space requirements - can be brought into practitically any nursery on earth at a 6 foot height, the list just goes on and on. Degroot's Spire - the same holds true for. Although, now you're looking at paying the bigger bucks. What I imagine for your purpose is a Holmstrup planted every 24".. Ken's suggestion of 18" for Degroot's seems good there, for that cultivar. Pruning: cut em flat across the top and walk away. It's that simple. Anything else and you're creating more work for yourself in the end. Hetz Wintergreen aka Wintergreen is now encroaching into that plant that after time will require that you maintain the entire plant, meaning, your ladder ain't gonna fit very well into that spot. Then... it just grows too fast. Wrong plant. Don't even consider Woodwardii either. Hell that's 10x the wrong plant. You want height not width. If it were possible to find larger plants: Malonyana and/or Malonyana Aurea would be welcome to that site. These selections are all pillars, which is an important concept in your design. They grow vertically and not (very much at all), horizontally. I've seen a 30 foot tall hedge in zone 4a in Iowa of Holmstrup and it was outstanding. I was on a garden tour this summer.
