Why are my Witch hazel 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.

Whether you think your plants are getting too much water, cut back on how often you water them, and take the following measures to see if they might be nutritionally deficient:

Here are some signs of yellowing caused by the many deficiencies on the Hamamelis virginiana in question:

  • Yellow patches between leaf veins on elder leaves are the first sign of magnesium shortage. Veins continue to be green while the leaf’s core turns yellow. The leaf’s edges yellow last.
  • Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
  • The newest leaves are first affected by sulfur deficiency, rendering them completely yellow.
  • Insufficient potassium causes the leaf edges to turn brilliant yellow while the interior of the leaf stays green. Older leaves show the symptoms initially, and the leaf edges quickly darken.
  • A broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new leaves as well.

Our Solution

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 Witch hazel sunburned?

It is quite easy to find out if your Witch hazel (Hamamelis virginiana) has been burned by the sun. Just like on us, your plant will change color in this case, it will start to turn yellow or white.

Sunburned

As we saw above, the leaves of your Witch hazel can also change color if it receives too much water or insufficient light.

To find out if the yellow leaves have been sunburned, look at the part of the bottom that is tinted closer to the base. The yellow leaf is probably burnt and not something else if this portion stays greener.

Why are my Witch hazel leaves turning brown?

Most of the time, leaves of a Witch hazel 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 Hamamelis virginiana in direct sunlight?

No! Don’t leave your Hamamelis virginiana (or Witch hazel) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.

Our Solution

The remedy, as said in the paragraph above, is simple: just move your plant’s Witch hazel out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.

Why are my Hamamelis virginiana leaves drooping or wilting ?

This typically occurs when your Hamamelis virginiana gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.

Drooping

An easy way to know if your Hamamelis virginiana 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!

Our Solution

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 Witch hazel 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 Hamamelis virginiana

Water Occasionally

Water is necessary for your plant to live, but timing and amount of watering must be balanced. Overwatering could have disastrous effects on your own name, as we already mentioned.

You can tell if your plant needs water by touching the soil; if it still feels damp, it’s usually preferable to wait a few more days.

Always keep temperatures stable

It is also a good idea to keep your Hamamelis virginiana at a stable temperature (especially if it is kept indoors!). At GreenShack, we generally recommend staying in the 65 and 85 degrees F range. Of course, do not place your Hamamelis virginiana near a source of hot (or cold) air such as A/C units, radiators or the like.

Keep your Witch hazel 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.

This would also make the pests happy, a real descent into hell for your Witch hazel.

To remove the dust, gently rub the plant’s leaves with a microfiber cloth. Dust can be removed more easily with a damp cloth, but stay away from corrosive substances like rubbing alcohol!

Keep drainage in mind

If you tend to overwater, you need to pay attention to your drainage, and we advise choosing a saucer and a pot with drainage holes if they are not already there.

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!).
