Question: SOS hedge
Hi, I'm your attentive reader and I need advice. In my garden I planted a viburnum hedge but a whole side got totally annoyed! At first I thought it had happened because of too much water because watering the lawn inevitably also watered the viburnum but then I noticed that in reality the water reached all the plants and yet only some were dry. On reflection I realized that the dried ones were those planted where previously there had been another hedge, I can't say the exact name but they were certainly conifers. Can there be a link? In that case what could I plant to avoid the same result? I thank you for the advice that will surely be precious.
Answer: SOS hedge
the viburnum are resistant and vigorous shrubs, which tolerate frost and heat, including drought, with beautiful evergreen foliage and a flowering that looks like a shower of white flowers; it is not easy to think of replacing them, also because they generally do not suffer from diseases or parasites. In fact, the fact that the viburnums that are known to dry out are precisely those planted where there was another hedge before may be the main reason, but not because the previous hedge has left something in the ground that has damaged your viburnum. These shrubs fear few things, one of these is water stagnation, water-soaked soil, excessive watering. If your hedge, on the whole, has resisted very well, despite the watering given to the nearby lawn, the fact that only one side is drying up seems to show that the problem is in the ground. Most likely the land where the other hedge used to be before is too compact and poorly draining; while the one where before there was no hedge is of better quality, and allows the water to flow quickly. Now it is advisable to eradicate the sick viburnum, together with the earthen bread around the roots, and a little of the earth present in the planting pit. At this point you will have to work the soil well, mixing fresh soil and sand, so as to give rise to a well-porous and draining compound, which allows the water to pass well and make it flow out. Then you will be able to put new viburnum for your hedge, without fearing that the water from the stagnant lawn watering. Often such facts happen even when there is a garage or a basement below the hedge, and therefore the hedges are essentially positioned in a large natural vessel, and not in full ground. If that's your case, maybe you should try other shrubs, because viburnum loves a nice free space for their roots.
