In one sentence, describe what the following article is about: Topsoil (soil from the garden) is not used for green roofs because it's usually too heavy and tends to become too compacted. Use a mixture of organic and inorganic materials. Focus on keeping the elements lightweight but water retaining. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/c\/c1\/Build-a-Green-Roof-Step-6Bullet1-Version-2.jpg\/v4-460px-Build-a-Green-Roof-Step-6Bullet1-Version-2.jpg","bigUrl":"\/images\/thumb\/c\/c1\/Build-a-Green-Roof-Step-6Bullet1-Version-2.jpg\/aid688104-v4-728px-Build-a-Green-Roof-Step-6Bullet1-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class="mw-parser-output"><p>License: <a rel="nofollow" class="external text" href="https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/">Creative Commons<\/a><br>

In one sentence, describe what the following article is about: New growth on Wandering Jew plants often attracts tiny green insects called aphids. They're usually found near stems. One effective treatment is pinching off or pruning the affected stems and heavily misting the remaining plant with water. You can also use a hose or high-powered stream of water to blast them off of the leaves. Mist your plant often. When the humidity is low, your plant's leaves will turn brown, but periodic water misting will help the leaves stay vibrant. Keeping the leaves wet will also help with any aphid problems your plant may develop. Fill a spray bottle with water and just mist until the leaves are lightly moistened. Brown leaves can also be a sign that your plant is getting too much sunlight. In this case, make sure your plant is not directly in the sun by moving the pot or placing a filter, such as a curtain, in between the plant and the window. Try to use distilled or bottled water when misting the leaves for the best results. Leaves that lack their notable vibrancy and color are probably not getting enough sunlight. Gradually increase the amount of sun your plant receives so that you don't shock the plant. This might involve moving the pot closer to a window that receives more light or finding a sunnier spot in the yard for your plant. If the plant is fading in color, but the leaves are turning a faded yellow, the plant may be getting too much water and the roots are rotting. If this is happening, the plant is probably not putting on much new growth, if any. You'll need to cut out the portion of the plant that is rotting, make a cutting from a healthy part of the plant, and replant it.
Summary:
Treat aphids. Refresh brown leaves. Restore faded leaves. Remove root rot.
