In this blog post, I will share my experience with the browning issues of the Tradescantia Nanouk. For these reasons, placing the Tradescantia Nanouk in a sheltered area where it can receive bright indirect light is best. The severity of browning worsens when exposed to direct sunlight, dry air, and underwatering. The Tradescantia Nanouk will most likely develop brown spots under low humidity levels. And I’ve discovered that certain environmental factors encourage the spread of these browning eyesores. However, one irritating issue with the Tradescantia Nanouk is the appearance of brown spots. It also grows relatively quickly, which gives plenty of propagating opportunities. Treat them by removing the damaged leaves and spraying the plant with top-quality neem oil spray.The Tradescantia Nanouk is one of my favorite plants because it has these beautiful purple streaks that you don’t see in many other plants. Meanwhile, pests are another problem for yucca plants, especially mealy bugs.Īlthough these normally leave behind white spots rather than brown ones, the latter could indicate an infestation as well. To do so, cut back damaged leaves to the stem and spray your plant with a copper fungicide to prevent the disease from taking hold. However, you must take prompt action to prevent them from propagating further. 3) Diseases & Pestsįungal spores can spread quickly from leaf to leaf and manifest themselves in the shape of brown spots with a yellow halo, though they rarely take over a whole leaf. You should immediately attempt to flush the soil out using water free from salt but it’s possible that the plant may be too far gone to save. In serious cases, a white crust may appear atop the soil. If the soil in your garden has high salinity or you water the plant using a softener, the yucca may develop brown spots, tips or stunted growth. Salty water, however, can be a death sentence for yucca plants. These can initially appear as small brown spots on the fringes of the leaf, but will soon take over the whole extremity.Īlthough this is not actually detrimental to the plant’s health, fluoride toxicity can be unsightly, but a simple switch to distilled water and the problem will resolve itself in time. If the water with which you irrigate your yuccas has an excess of fluoride, it can cause their leaves to develop brown tips. In the future, only water when the top 5cm of the soil is dry. If they’re black, discoloured or squishy, you should carefully cut away the damaged parts and repot the remainder of the plant in a new container with good draining soil. They should be white and firm to the touch. To check your yucca’s root health, gently unearth them. Overwatering, on the other hand, is very easily done and will drown the plant’s roots, leading to a fungal infection which can manifest itself in the shape of brown spots. They’re part of the succulent family, which means they can store water in their foliage, so it’s highly unlikely that you’ll be underwatering them. Given that their natural habitat is normally a desert, it’s understandable that yuccas don’t take too kindly to overwatering. Here are some of the likeliest causes of discolouration, along with some pointers on how to address them. If you notice such signs on your plant, it’s a good idea to investigate the issue further and take remedial action before it worsens. One of the most common and clearest symptoms that all is not well with a yucca is the appearance of brown spots on its leaves, browning at its extremities or a general brown or yellow hue to the foliage. However, that doesn’t mean that they’re completely indestructible and you may find your plant is suffering from one or more maladies. Hardy yuccas are famous for their easy-going temperament and ability to withstand the harshest conditions.
