NOTE: In this article, New England aster and Symphyotrichum novae-angliae may be used interchangeably; in fact, Symphyotrichum novae-angliae is the botanical name for New England aster.
The New England aster is one of the best fall flowers. The plants have stems that can grow several feet tall. Many lance-shaped leaves extend from the stems, which have fine “hairs” or bristles. The daisy-like blooms appear in the late summer and early fall. The flowers are usually 1.5 inches in diameter and have purple and yellow centers. The blooms are popular with Pollinators.
New England asters can be planted in the spring to early fall in northern climates. In southern climates, it is best to plant them only in the spring and fall, as hot summer temperatures can be damaging to a plant that is not yet established. Asters bloom in their first year, and are fast growers.
Why does my Symphyotrichum novae-angliae roots have rot?
Root rot on your New England aster (Symphyotrichum novae-angliae) can be fatal if not treated with care. For this reason, we strongly recommend that you follow our guide to keep your plant alive if the symptoms occur: Root soft and blackened.
Why does my New England aster 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 answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Symphyotrichum novae-angliae being overwatered. We strongly advise you to remove the damaged plant parts, cut off the diseased roots and leaves, and then repot your plant in a new container with sterile potting soil.
Why does my New England aster have leaf spots?
This type of disease is one of the most frustrating for New England aster 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 New England aster leaves turning yellow?
In the world of horticulture, yellowing leaves are undoubtedly the most common problem. The two main causes of this problem are overwatering and a lack of nutrition.
When it’s overwatering, simply reduce your watering frequency, and if you think it’s a nutrient deficiency, here’s how to check it:
Each deficiency produces a different yellowing on the Symphyotrichum novae-angliae in question, here’s how to spot them:
- 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.
- Iron deficiency also shows as yellowing between leaf veins, but it hits young leaves on plant tops and branch tips first.
- Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
- 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 lack of nitrogen is indicated by a widespread yellowing. Older, inner leaves are the first to yellow. As the yellowing progresses, it eventually touches young leaves as well.
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 New England aster sunburned?
It is quite easy to find out if your New England aster (Symphyotrichum novae-angliae) 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.
As we saw above, the leaves of your New England aster can also change color if it receives too much water or insufficient light.
However, there is a way to tell if it is sunburn; look at the bottom of the yellow leaves, the ones that have a shaded area closer to the root, if this area stays greener, it is probably sunburned, not something else.
Why are my New England aster leaves turning brown?
The classic sign that a plant has been overexposed to direct sunlight and sunburned is the development of browning leaves. Rest assured that while this may probably save your plant from dying, it will adversely affect its growth.
Should I leave my Symphyotrichum novae-angliae in direct sunlight?
No! If your Symphyotrichum novae-angliae (or New England aster) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your New England aster is in such a state!
As explained in the paragraph above, the solution is simple, just place your New England aster in a place where the light does not reach it directly, in this way and with a correct watering, your plant should resume its life rather quickly.
Why are my Symphyotrichum novae-angliae leaves drooping or wilting ?
In most cases, this happens when your Symphyotrichum novae-angliae lacks water. This is especially the case for large plants, naturally they need more water than others.
An easy way to know if your Symphyotrichum novae-angliae 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 New England aster after a dry period in the belief that it requires a lot of water.
This is true, but the easiest way to end it is to give too much water at once. Instead, you should water the soil properly, returning to a peaceful watering rhythm.
Caring Tips for Symphyotrichum novae-angliae
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
Maintaining a consistent temperature for your Symphyotrichum novae-angliae 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 Symphyotrichum novae-angliae close to air conditioners, radiators, or other sources of hot or cold air.
Keep your New England aster Dust-Free
This one concerns indoor plants, just like on your furniture, dust is also deposited on the leaves of your indoor plants, the problem is that it can prevent them from receiving the necessary light, this would slow down (or even stop) the photosynthesis process, and eventually, they would lose their colors.
This would also make the pests happy, a real descent into hell for your New England aster.
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 need to keep an eye on your drainage, we advise you to opt for a pot with drainage holes if it is not already the case and a saucer.
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!).
