I live in a region where Norway spruce grows wild, and in my experience, the lower shaded branches shedding their needles and dying is perfectly normal for these trees. For the tree, there's no point in keeping these branches alive when the same energy and nutrients can instead be directed towards the upper branches that receive more sunlight. Here's a nice ...

Once the needles turn brown or fall off a branch, regeneration will not take place, though you may find growth at the tips of those branches. Probably the best thing to do is remove the affected branches at the base leaving a clean trunk - hopefully this won't notice because of the shrubs around it. Loss of the lower branches is not that unusual - we have a ...

I believe that the term you're referencing is incorrect; green plants get their energy from the leaves, not the roots. Here's an explanation from a certified arborist. As you noted, the roots act as both an anchor for the tree and as storage for the energy produced by photosynthesis. There's no energy production going on in the roots. There is no one rule ...

I used a U of IL home fruit tree pruning guide : The instructions were " prune when the shears are sharp". Caution - With all the political correctness today , they may have revised these instructions . On the other hand, it is easier to see branches with no leaves. And very young trees might put out new growth if pruned in late summer, which would ...

You won't be able to plant in between the trees because the soil will be full of roots from them - if you dig out or break too much root material, the trees will die. Anything you attempt to plant in between will also be in direct competition with the existing trees for nutrients and moisture too. You should be able to plant 3 feet away, maybe in that strip ...

Just take out any problem growth (like crossing branches that may rub and allow disease to take hold) as far back to the main trunk as possible, so you won't get more problem growth by being too cautious. Then spend the rest of the year deciding exactly how you want to "shape" the tree next winter. Don't forget that the tree doesn't care whether or ...

You were sold a tree that should never have been on the market. I'm guessing that the lower three feet were covered by a flexible white plastic tube, right? The purpose of this tube in a nursery is supposedly to equip the tree with protection from critters, but in reality it usually serves as a home for insects and a disguise for problems such as canker and ...

It looks like these seeds are from an Acer, based on the "helicopter" structure. To be able to tell the species you will need more information, pictures of the leaves or from less dried up seeds.

There are a number of ways of interpreting your question about energy in plants. The answer you are about to get from me will be a bit different from @Jurp excellent answer, this one through the lens of hibernation. We know that some animals store fat and sleep during winter and rely on the energy stored in the fat to get them through winter and have ...

Spider mites attack lower branches , starting near the trunk of spruce trees. Dormant oil should control them but it may require a few applications months apart, They are tiny and you have to look very closely and magnification helps. To get to the center of the tree I have taken the sprayer in to the trunk of the tree and sprayed rather than try to spray ...

Yes, it shouldn't be a problem. This particular variety has a natural tendency to grow in a pyramid shape, and hollies generally exhibit strong apical domination, so the removal of the central leader just means another one or two will appear. This variety is said to get between 15 and 20 feet tall, with a spread of 8-15 feet.

It might live but is has been severely weakened by decay of the heart wood . The bark layers can keep it alive as water and nutrients flow through the various bark layers but it needs the center wood for strength. The decay will continue to develop.

I find Norfolk Island Pines grow too big for a house plant in a few years with only minimal ordinary fertilizer so I would do nothing to increase growth.

I have tapped may Japanese Maples for making syrup. Interestingly, there is a distinct soy flavor to the syrup, and we like it for dumpling sauce.
