Lowell, the two species are pretty similar. If you live in the mountains and the tree is growing there naturally, it's probably monticola. If it was planted at some point, it's probably strobus. Monticola is fairly rare in the nursery and landscaping trade, while strobus is very common. The…

I am having a difficult time distinguishing the three trees in my backyard between eastern white pine and western White Pine. I am located in Oregon. All the information I have found regarding eastern and western white pines does not go into detail regarding how to tell the two apart. Can anyone…

Rita, it all depends on the drainage ... with average drainage, watering once a week with a slow trickle from garden hose for an hour should be good. You didn't say where you are at planting, the root ball should have been thoroughly saturated proper drying is needed between watering.

are you working with weeping white spruce (like above) or weeping Norway spruce (or any other of the scores of weeping spruce out there)? weeping white spruce has a dependably upright lead shoot, the others not so much.

Hello Rita, planting a B&B conifer in mid-summer during a summer of historic heat waves is quite likely a death sentence. During the process of digging in late winter, the roots are absolutely decimated. There's not enough fiber down there to absorb the water you're giving it. In the future, when…

I have a weeping spruce and the top is curled down not growing straight up why?

Hello, I have been helping my friend with his landscape. He planted a 5’ B&B Chamaecyparis obtusa ‘Filicoides’ about a month and half ago. It has brown needles along the outer edges of branches/needles. Can it be caused by too much watering? Wish I could attach a picture of the plant. What is the…

Does anybody have thoughts on our conifers that still look good to stay alive for the rest of the year? I lost too many conifers this summer. Watering was not enough.

yes; but it will take many years.

Does root growth cause wall or sidewalk damage when planted at least 3 feet away?

How tall will a green giant arborvitae get when planted in a large container ? 6 hours of sun. I just purchased 5 to screen deck in an urban area. Thanks

congratulations, Erica ... very few have gotten a 'Blue Surprise' to stay alive so long. The splaying you describe may become known as "typical in older plants." Right now we don't know because so few specimens have gotten so large. You can try doing some light shearing to rogue branches, but…

I have one, planted in 2000, which is now a good 15+ ft tall. A surprise indeed! It is about 4’ wide. Although I didn’t plan for this height, it is beautiful. The problem is it is starting to splay (no significant snow in our area). I tuck these limbs in but that only works temporarily. Is there…

Hello Punta ... Horstmann Nursery of Schneverdingen, Germany named 100s of conifer cultivars, all with the cultivar name 'Horstmann'. It's all quite messy and confusing. As for Picea abies, Günther Horstmann named 16 of them with the cultivar names 'Horstmann no. 1' through 'Horstmann no. 16' ...…

What about Picea abies 'Horstmann' ? There is a nursery here in Punta arenas (Chilean Patagonia) owned by a German family, and they sell this fir and also a yellow form of Picea abies, but sells it as 'Cesky pine'

Hello David, I just bought and planed 3 of these in my yard and was wondering if they can be trained to be more shrub like than upright. I was thinking of weighting some of branches once it gets larger. In your experience do you think it would work? BTW I love the asymmetrical growth pattern of…

Hello Where in Australia can I buy this tree?

Posted 10 days ago by Andrea Allred to flexilis

Hello I am seeking advice/info about my 'Vanderwolf's Pyarmid' pinus flexillis - in No. CA zone 9B - I planted it last December and it was doing great. It's been super hot here and I think I over watered it.?? It is turning brown/yellow-ish and I am heart-broken. What should I do?? It is now end of…

Hi Denise ... never spray a chemical product on anything until you're 100% certain of what you're dealing with. For example, if you're dealing with fungus, an insecticide will only kill a lot of beneficial insects and do nothing for the fungal infection.

We have a privacy row of Emerald Green arborvitae bushes that are over 6 feet tall at least five years old - one is getting very thin or see-through with rusty-brown branches that are unlike the normal loss of internal foliage. Many of the cones are brown & the inside branches also have a whitish…

HI Anthony. Google says the optimum PH for most conifers is 5.5 ... The difference between lime-green and dark-green is a few shades of deeper color saturation in the latter. This could be a result of a different cultivar being mixed up in your batch, or that it's gotten itself established quicker.

Posted 11 days ago by Anthony Vaccariello to Green Giant

What is the preferred pH for Green Giants? I have 15 Green Giants that have a beautiful glossy lime-green foliage. One is dark green. What is the difference?

I have a spot in a courtyard that gets mid day and afternoon sun. I live in Dallas, TX. Will 'Black Dragon' live here? I will have irrigation.

Posted 12 days ago by David Olszyk to Glauca

dead and dry branches will never recover. If the dead bits bother you, then by all means, you should remove them.

Posted 13 days ago by Tim Stevens to Glauca

My 6’ blue Spanish fir has heat damage with several end branched and it main top trunk dried and brown. Should I prune the dead sections?

Your work on the Pine trees are impressive. Thank you. Your website assisted me to complete my school project.

Probably your best shot at locating one of the in the Carolinas would be to check with Appeldoorn Landscape Nursery in Bostic. Not exactly around the corner from you but if anyone has this tree, it will be here.

John try Bill Castellon Landscaping. If he doesn't have one, he might know where to get one. Yes, they can be sculpted, yes you can grow them in Santa Clara.

Hi Lori ... dead brown new growth is dead forever. You probably did no harm in removing it unless you cut into some live material and took some dormant buds with the dead stuff. If older growth is still green, there's still a chance that it'll re-sprout next spring, but it's going to be weak for a…
