NOTE: The terms Kale and Brassica oleracea are identical in this text; in reality, Brassica oleracea is Kale’s biological word.
It’s a form of cabbage that doesn’t have a tightly formed head like most cabbages, and it’s grouped in the cooking greens category with collards, mustard, and Swiss chard. There are shades of green, purple, and other colors on the textured and curly leaves of the kala plants. The plant can grow from seed to harvest in three months.
It can be planted in the late winter or early spring and in the late summer for a fall to winter harvest. This biennial plant takes two years to complete its growth cycle, so it grows leaves in its first year, while seeds and flowers develop in its second growing season.
Why does my Brassica oleracea roots have rot?
If left untreated, root rot on your Kale (Brassica oleracea) 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 Kale have gray mold spots?
Gray mold spots are a type of fungus that is found a lot in flowers, and spreads quite rapidly. If you notice brown (or gray) spots, it is probably this fungus. Don’t ignore these symptoms, as they may end up killing your plant.
The solution is quite logical when you know the cause of the problem. Most of the time, it is due to overwater of the Brassica oleracea. 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 Kale have leaf spots?
This type of disease is one of the most frustrating for Kale 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 Kale 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:
Here are some indicators of yellowing on the Brassica oleracea brought on by its numerous flaws:
- 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.
- Leaf edges turning bright yellow but inside leaf remaining green are signs of potassium insufficiency. The symptoms first appear on older leaves, and the leaf edges quickly become dark.
- A broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new 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 Kale sunburned?
You can easily tell if your Kale (your Brassica oleracea) 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, the leaves of your Kale can also change color if it receives too much water or insufficient light.
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 Kale leaves turning brown?
Most of the time, leaves of a Kale 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 Brassica oleracea in direct sunlight?
No! Don’t leave your Brassica oleracea (or Kale) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
As stated in the paragraph above, the cure is straightforward: simply position your plant’s Kale so that it is out of direct sunlight. With proper watering and this method, your plant should quickly come back to life.
Why are my Brassica oleracea leaves drooping or wilting ?
In most cases, this happens when your Brassica oleracea lacks water. This is especially the case for large plants, naturally they need more water than others.
An easy way to know if your Brassica oleracea 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 Kale 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 Brassica oleracea
Water is essential to the survival of your plant, however, it is important to balance the rate of watering. As we explained above, overwatering could have fatal consequences for your Brassica oleracea.
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 Brassica oleracea 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 Brassica oleracea close to air conditioners, radiators, or other sources of hot or cold air.
Keep your Kale 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 Kale, this would be a true descent into hell, and it would also appease the pests.
To remove the dust from the leaves of your plant, take a microfiber cloth and gently rub the leaves. You can wet the cloth to make it easier to remove the dust, but never use corrosive products (such as 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!).
