Hardy yuccas are noted for their easy - going disposition and power to resist the harshest weather .
“ Generally Yuccas are very various industrial plant , and asunder from frost damage in very cold-blooded wintertime , the audacious mintage rarely put up plant wellness problem , ” say Master Horticulturist Peter Lickorish .
However , that does n’t mean that they ’re completely undestroyable and you may find your works is suffer from one or more malady .
One of the most common and clearest symptom that all is not well with a yucca is the appearance of brown spot on its leaf , browning at its extremities or a general brown or yellow hue to the leaf .
If you comment such augury on your industrial plant , it ’s a good thought to investigate the issue further and take remedial action before it decline .
Here are some of the likeliest causes of discoloration , along with some pointers on how to direct them .
1) Overwatering
Given that their rude habitat is unremarkably a desert , it ’s understandable that yuccas do n’t take too kindly to overwatering .
They ’re considered to besucculent plants , which means they can stack away water in their foliage , so it ’s highly unlikely that you ’ll be underwatering them .
Overwatering , on the other manus , is very well done and will drown the plant ’s root , leading to a fungal contagion which can evidence itself in the form of browned spots .
To check your yucca ’s root health , lightly unearth them .
They should be white and truehearted to the touch .
If they ’re black , discoloured or spongy , you should cautiously write out away the damage parts and repot the remainder of the plant life in a new container with good draining soil .
In the future , only water when the top 5 atomic number 96 of the filth is ironical .
2) Fluoride Or Salt Toxicity
If the water with which you water your yuccas has an excess of fluoride , it can cause their leaf to develop brown tips .
These can ab initio seem as small brown spots on the fringes of the foliage , but will soon take over the whole extremity .
Although this is not actually detrimental to the industrial plant ’s wellness , fluoride toxicity can be unsightly , but a simple substitution todistilled waterand the problem will settle itself in prison term .
Salty piddle , however , can be a dying time for yucca plant .
If the land in your garden has eminent salinity or you water the plant using a softener , the yucca may develop browned smear , tips or stunted growth .
In serious lawsuit , a lily-white insolence may appear atop the soil .
You should immediately attempt to flush the ground out using water system loose from salt but it ’s possible that the plant may be too far gone to hold open .
3) Diseases & Pests
Fungal spores ofConiothyrium concentricumcan diffuse quickly from foliage to leaf and manifest themselves in the Supreme Headquarters Allied Powers Europe of dark-brown spots with a yellow halo , though they seldom take over a whole leaf .
This contrasts with the more general browning often resulting from overwatering .
all the same , you must take immediate action to prevent them from propagating further .
To do so cut back damage leaves to the stem and clear any fall leaves from the base of the plant .
keep water from sitting on the foliage and ensuring good drain is key too .
Potted outdoor works could be moved to a porch , for example .
Meanwhile , pests are another job for yucca plants , specially mealy bugs .
Although these normally leave behind white-hot spots rather than brown ones , the latter could indicate an infestation as well .
Treat them by remove the damaged leaves and spray the plant with works oil colour .
