Why there were many cones on the thuja and whether it is necessary to delete them

Too many cones-seeds have formed on young thuja this year. What is the reason and what to do about it? Get rid of them or leave so? The view of the bushes became untidy. I want to help them somehow ...


Why do cones appear on the thuja and whether to remove them

Anyone who is even a little familiar with the principles of building garden compositions or simply fascinated by the beauty and grandeur of coniferous plants, will surely give the palm of primacy to various species and varieties of thuja. It's just a lifesaver for a garden designer. Without it, in landscape business, by no means, it is impossible, because this is a vertical accent in the garden, and an element of year-round decorativeness, and fertile material for hedges ...

Yes, these plants are beautiful, out of competition. Almost perfect, until covered in a certain period with small brown cones. Is it good or bad? Some people really don’t like the fruits, because from afar they resemble dried, diseased tops of shoots or brown growths. What to do in this case, how to save beauty? Does it really remain to approach each instance of this plant with a bucket and secateurs and cut, cut, cut, until all are cleaned up? Of course, you can do just that if the thuja on the site is only two or three specimens and they are young and fairly undersized. Perhaps this is the best option for this case. But the laws of nature have not been canceled.

Thuja cones are valued in folk medicine: they make ointments and tinctures that fight many diseases

Cones are seeds; next year they will appear on the plant again. In a year, your arborvitae will become higher, it will be harder to jump with a pruner and a bucket, breaking off the excess.

There is an opinion that thuja gives out many cones after a dry summer. Thus, the plant, which is under stress, thinks that it threatens to completely dry out, and tries to compensate for this by reproduction. Water your plants more abundantly during periods of drought.

You can also advise killing two birds with one stone: cut the thuja. Thus, you will get rid of brown cones and form a beautiful crown. Thuja after cutting will lay more buds and next year new shoots will grow from them. The plant will become more fluffy, “stuffed”, slender and generally the way you want to see it: a cone, a column, a ball, a spiral or just a neat bush. Of course, this will not happen in one year, but after a couple of years of haircuts you will begin to notice the result.

In the case of planting thuja in a row by regular haircuts, you can not only save them from cones, but also form a dense hedge of a given height.

When forming plants, a number of conditions must be observed.

  1. Dates. Conifers are pruned in the spring before new shoots are released. In this case, it is desirable to cut last year's no more than one third. Then you can re-trim in late June - early July. The more regular the haircuts will be, the more noticeable the result. I mean, if you cut the plant this year, do not forget to do it next year.
  2. Use a quality, well-ground garden tool. Small plants in the second or third year after planting can be trimmed with pruners. Then you can’t do without clippers. A good gardening tool, in my opinion, is produced by the Japanese firm ARS.
  3. Top dressing. Do not forget to feed plants weakened by haircuts. In principle, thuja well tolerate the formation of the crown with a haircut. But still this event is somewhat stressful. Therefore, do not forget to regularly feed your arborvitae with special fertilizers for conifers (they can be purchased at any gardening shop) and anti-stress medications such as Epin-Extra or Zircon. Give the advantage of the mineral. More magnesium, less nitrogen. From organic, vermicompost or rotted compost is suitable. Fodder in the early spring after snow melts and a second time in the summer. It is better to complete them by August, so as not to provoke the growth of new shoots, which will not have time to ripen by winter.

If planting with an artificially defined crown shape is not planned at the site and you like the natural landscape style, then it is worth considering this at the stage of planting planning and buying thuja varieties with the least susceptibility to seed formation. Such, for example, is the favorite variety of thuja western Smaragd. This is indeed one of the most beautiful columnar varieties with a pleasant emerald green needles, not prone to seasonal browning.

Thuy Smaragd less prone to seasonal color changes

If we take a different grade of Brabant for comparison, then it produces much more cones, the crown is more loose and prone to a winter change in color to a browner.

Brabant grows faster than Smaragd, so it’s more suitable to create a hedge

Remember - nobody canceled the laws of nature! Maybe you should come to terms with natural beauty, because it's like freckles on a woman's face - a kiss from the sun!
