Yes, you can put sand on top of your potted plants, but it comes with a few specific trade-offs. It is highly effective at preventing fungus gnats from laying eggs in your soil, but it can make it harder to tell when your plant needs to be watered.
Sand or top dressing is perfect for preventing the fungus gnats from laying eggs in your soil. Simply cover your potting mix with a small layer of sand and you are good to go. This creates a barrier that the gnats cannot get through. If they can't lay the eggs, they can create an infestation.

A loose, well draining soil or soilless mix is ideal. A peat based mixture with lots of perlite, vermiculite or sand will do the trick. For a pre-mixed formula, we find that a cactus/succulent blend is perfect! Aglaonema are slow growers and therefor do not need, or want, to be repotted very frequently.
Mixing sand with potting soil is not recommended for most standard plants, as it can make the soil much too heavy and dense. However, it can be beneficial for specific uses like growing succulents, if you use the right kind of sand.
Best Plants for Sandy Soil in Full Sun
Plants prefer to rest between waterings. Keeping the soil too moist all the time can rot the roots. OVERWATERING is the #1 killer of houseplants.
If the soil is too moist, your cactus can develop rot. This is a common error beginning cactus gardeners make. If in doubt, err on the side of under-watering. Correct watering for all growing conditions are explored in more depth in the DVD, Those Captivating Cacti.
An Aglaonema (Chinese Evergreen) has an average lifespan of 5 to 10 years indoors, though some specific varieties can live for 10 to 15 years with optimal care. They are slow-growing herbaceous perennials that tolerate low light and neglect, but they require proper maintenance to reach their full longevity.
Certain indoor plants are notorious for their demanding environments and hyper-specific care routines. The absolute hardest houseplants to keep alive include the Maidenhair Fern, which quickly turns to dust if its delicate soil dries out even slightly, and the Calathea (or Peacock Plant), which requires distilled water and 60%+ humidity.
'Certain vegetables, such as carrots, parsnips, and other root crops, require a significant depth of soil to develop their roots properly,' warns Morris. 'Shallow pots or raised planters aren't ideal for these plants because they need ample vertical space to grow their long taproots.
In gardening, the "3-year rule" is a common guideline describing the three-stage establishment cycle of new perennial plants, shrubs, and trees. It states: "The first year they sleep, the second year they creep, and the third year they leap."
Quick Fixes
Yes, dry coffee grounds can help deter fungus gnats by acting as a physical barrier that prevents females from laying eggs in the soil. However, they must be completely dry. Moist coffee grounds are a breeding ground for fungus.
Some houseplant parents like to put a layer of sand on top of their potting soil. Adult fungus gnats lay eggs in moist areas, so the dry surface will prevent them from doing so.
Covering Cacti
Avoid using plastic, as it traps moisture and can lead to rot. You can also use Styrofoam cups on the apex of columnar cacti to help insulate the tender tips. Take care not to remove the spines as they will not regenerate.
The answer is no. Despite being mild for dishes, it isn't mild for living foliage. Dish detergents can burn leaves, damage the natural protective layer, and weaken plants. Instead, gardeners should use potassium soap, which is specifically formulated for safe use on plants.
7 things you should NOT do with newly arrived succulents
Aglaonemas will not tolerate wet, soggy, un-drained soil, so be sure to use good quality, well-drained potting soil. We recommended that the pot be at least 2 to 4 inches bigger than the current pot.
Many indoor houseplants, such as, begonias, coleus, polka-dot-plant, ivies and philodendrons root easily in water. Other plants, including many woody plants such as hibiscus and citrus will not root well in water. They usual rot before rooting.
One of the classic ways to develop thicker growth, jump-start new stems, and promote a more compact plant is through pinching. Pinching out simply means using the thumb and index finger to remove vegetative growth.
Several plants in nature contain potent toxins that can lead to muscle weakness or paralysis if ingested or, in some cases, touched. Identifying these plants is crucial for safety and preventing accidental poisoning:
The classic plant that universally says "I love you" is the Red Rose. However, if you are looking for long-lasting houseplants or specific symbolic meanings in the Victorian language of flowers, there are several wonderful alternatives to express your deepest affections.
