NOTE: In this article, White Willow and Salix alba may be used interchangeably; in fact, Salix alba is the botanical name for White Willow.
You can argue that the Salix alba is one of the most important trees in the history of mankind. The chemicals needed to make aspirin and other pharmaceutical products have been provided by white willow. The straight species of Salix alba is usually avoided for horticultural purposes in favor of one of its cultivars.
White willow trees are hard to find in the nursery trade because of this. If you want to include the species in your garden design, you should only look at the species cultivars. The species cultivars make lovely additions to wet areas and spaces that may be on the damp side, such as the edge of a rain garden.
Why does my Salix alba roots have rot?
If left untreated, root rot on your White Willow (Salix alba) can be fatal. For this reason, if the symptoms appear, we highly advise that you adhere to our recommendations to keep your plant alive: Blackened and softened roots.
Why does my White Willow have gray mold spots?
Gray mold spots are a specific fungus that regularly harms flowers and spreads swiftly. If you notice any brown (or gray) spots, this fungus is probably to cause. You risk your plant dying if you ignore these warning indications.
The solution is quite logical when you know the cause of the problem. Most of the time, it is due to overwater of the Salix alba. We advise you to remove the infected parts of the plant, cut off the infected roots and leaves, then repot your plant using sterile potting soil and a clean pot.
Why does my White Willow have leaf spots?
This type of disease is one of the most frustrating for White Willow owners, we give you all the leads to spot and save your plants that present symptoms such as leaves that suddenly change color, or wilt/droop.
Why are my White Willow leaves turning yellow?
Yellowing leaves are arguably the most prevalent issue in the gardening world. Overwatering or a lack of nutrients are the 2 main causes of this issue.
Reduce your watering frequency when you fear your plants are being overwatered, and follow these steps to determine whether they may be lacking in nutrients:
Each deficiency produces a different yellowing on the Salix alba in question, here’s how to spot them:
- Magnesium deficiency starts as yellow patches between leaf veins on older leaves. Veins stay green as yellow moves from the leaf center out. Leaf edges turn yellow last.
- Another indicator of iron deficiency is yellowing between leaf veins, but young leaves on plant tops and branch tips are first affected.
- Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
- Potassium deficiency shows itself when leaf edges turn bright yellow, but the inner leaf stays green. Older leaves show symptoms first, and leaf edges soon turn brown.
- Nitrogen deficiency shows up as a general yellowing. Older, inner leaves turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves, too.
You only need to act in accordance with the symptoms listed above. You can address a potassium or nitrogen deficiency by buying a particular soil, and a gardening store consultant will be able to advise you on how to do that. Furthermore, you can also limit how frequently you water your plants.
Is my White Willow sunburned?
You can easily tell if your White Willow (your Salix alba) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.
As we saw above, if your White Willow receives too much water or not enough light, the leaves may also change color.
The bottom of the yellow leaves with a shaded area closer to the base can be examined to determine if they have been sunburned. If this part remains greener, the yellow leaf is most likely sunburned and not something else.
Why are my White Willow leaves turning brown?
Most of the time, leaves of a White Willow that turn brown is a sign that your plant has been sunburned, it has probably been exposed to too much direct sunlight. Don’t panic, your plant probably won’t die from this, but its growth will take a hit.
Should I leave my Salix alba in direct sunlight?
No! If your Salix alba (or White Willow) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your White Willow is in such a state!
The remedy, as said in the paragraph above, is simple: just move your plant’s White Willow out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Salix alba leaves drooping or wilting ?
This typically occurs when your Salix alba gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
An easy way to know if your Salix alba is lacking water is to under-weigh its pot, if it looks light, it means that the soil and the roots are probably quite dry, and therefore need water!
In order to ensure that the roots of your plant receive the water’s benefits, you must first moisten the soil in the container if it is absolutely dry. One common error is to immediately drown the White Willow after a dry period in the belief that it requires a lot of water.
This is the case, but giving too much water at once is the best way to finish it off, you should actually water the soil normally, resuming a quiet watering rhythm.
Caring Tips for Salix alba
Your plant needs water to survive, but it’s crucial to balance the amount and timing of watering. As we previously mentioned, overwatering could be catastrophic for your Salix alba.
Touching the soil will let you know whether your plant needs water or not; if it still feels damp, it’s generally best to wait a few more days.
Always keep temperatures stable
Maintaining a consistent temperature for your Salix alba is also a good idea, especially if it is kept indoors. At GreenShack, we typically advise reserving a temperature between 65 and 85 degrees F. Of course, avoid positioning your Salix alba close to air conditioners, radiators, or other sources of hot or cold air.
Keep your White Willow Dust-Free
This one relates to indoor plants. Just like your furniture, dust collects on the leaves of your indoor plants. The issue is that this can block the photosynthesis process from starting, which would cause the plants to gradually lose their color.
For your White Willow, this would be a true descent into hell, and it would also appease the pests.
Take a microfiber cloth and gently massage the plant’s leaves to get rid of the dust. Use a damp cloth to make dust removal easier, but avoid using corrosive materials like rubbing alcohol!
Keep drainage in mind
If you have a tendency to overwater, you should be mindful of your drainage, and if they don’t already have them, we suggest selecting a saucer and a pot with drainage holes.
You can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the interim if your pots don’t already have holes in them. This will help to form a channel so that the water doesn’t pool there for too long (preventing the rot of the roots!).
