7/22/2023 0 Comments Types of pine trees![]() You can see there are not a lot of different things that will show you there is a problem, so knowing what the problem actually is depends a lot on what kind of pine tree you have. ![]() Several different organisms can cause them. Round swellings and growths on the stems – these are called ‘galls’, and although unsightly they are rarely dangerous to the tree. If they are, nothing is wrong, but if it is younger needles that are yellow, you could have a problem. These will always be the last needles before the bare part of the stem. This shouldn’t be confused with the normal, season browning and falling of older needles. Later they will turn brown, either completely or in bands. Yellow needles – sometimes needles turn yellow, sooner than they normally would. Notice if they are on new shoots only, before the needles have had time to develop fully, or if a whole branch of mature shoots has died. As it dries it turns white and flakey around the edges of the flow, or it may dry completely into white or grey flakes on the bark.ĭead shoots or branches – these might be anywhere in the tree – foresters often call them ‘flags’. This can even collect at the bottom of the tree, on the ground. Resin running down the trunk – If the bark is injured by diseases sticky resin often escapes and flows down the bark. Pine trees only have so many ways to tell us they are not doing well, and there are several things we might spot that are indicators of diseases. An earlier blog on Diseases of Maples has been a popular resource for our readers, so to continue giving that basic information, this time we are going to look at the diseases that pine trees may suffer from, which one’s matter, and what to do about them. So for gardeners, it helps to have some knowledge of diseases, to encourage the good, and separate the bad from the merely ugly. Other diseases look dramatic but do very little harm. Most often it is a lower-level disease that picks away at a particular type of tree, like the Verticillium Wilt that is spreading through maple trees these days. Sometimes it is a major outbreak, like Dutch Elm Disease, that decimates a much-loved tree. This is usually true, trees are remarkably tough, and most grow and survive without problems. ![]() We hope that our tree will grow and flourish, living out its life – which will certainly be decades, and perhaps even a hundred years or more – free of problems that threaten it. Their cones are egg shaped and can be collected for decorations or for fun.Planting a tree is an action full of hope. When you think of a pine cone you are probably envisioning a Red/Norway Pine’s cone. These can be identified by their 2-4 inch length needles that also grow in groups of twos. Red/Norway Pine:The last type of pine tree to search for is the Red/Norway Pine. Another give away that you are seeing a Jack Pine is that their cones stay closed and bloom like other pine cones. You can identify this species by looking for short and stout needles that grow in groups of two. Jack Pine:The Jack Pine is another species of pines that are in abundance in Northern Minnesota. Another way to pick out a White Pine is that they can become 80 feet tall and 40 feet wide. White Pine needles are longer than their counterparts therefore are more flexible and softer. White Pine:When you are looking to identify a White Pine look for needles that flow in the wind. Now that you know a little more about how to identify a pine tree let’s look at the specific types.
