Turnip greens turn purple when they don’t get enough phosphorus. Phosphorus is an important nutrient for many crops—when plants, like turnips, don’t get enough of it from their soil, they’ll have a phosphorus deficiency and their roots won’t grow normally.
Why is my plant turning purple?
Due to the role phosphorus plays in converting and transforming energy within the plant, there can be abnormalities with sugars and other levels. Excess sugar levels can lead to ‘anthocyanin’ pigments developing within the leaves; this is what produces that red/purple colour.
Are purple top turnips edible?
The turnip tops and bulbs are both edible, highly digestible and a good source of sulfur. Purple top turnips should not be overseeded in excess of 2 lbs/ac in mixes.
Why do turnips turn black?
Black rot caused by the bacterium Xanthomonas campestris pv. campestris (Xcc) is a highly destructive disease of crucifers, including turnips. In fact, the disease was first identified on turnips in 1893 and remains a severe problem today.
How long does it take for purple top turnips to mature?
about 55 days
The most vigorous root growth takes place during periods of low temperatures and they will reach maturity in about 55 days. Soil temperatures should be at least 50° for germination.
How do you fix phosphorus deficiency?
Phosphorus deficiency can be controlled by applying sources of phosphorus such as bone meal, rock phosphate, manure, and phosphate-fertilizers.
What is the fastest way to add phosphorus to soil?
What is the fastest way to add phosphorus to soil? If your plant is in desperate need of a phosphorus boost, start with a regular schedule of foliar kelp fertilizer. At the same time, add a rapid release phosphorous fertilizer to the soil, like bone meal or fish meal.
Do turnips come back every year?
Now Answered. Dill, radishes, arugula, cilantro, broccoli raab, turnips, and any form of mustard will yield mature seeds in time for fall reseeding in most regions if allowed to flower and set seed.
Can turnips be purple?
Purple Turnip tops are the root tubers of the turnip plant. The exposed turnip above the soil line during the growing process will be a bright purple color as its name suggest while the part that remains underground will be white. When harvested the turnips have a smooth skin and about 7 to 10 centimeters in diameter.
When should I harvest turnips?
30-60 days
In general, turnips mature anywhere from 30-60 days after planting, depending on the variety and growing conditions. Quick-growing varieties can be harvested in 4-5 weeks, while longer-maturing varieties may take up to 8-10 weeks.
Can you eat bolted turnips?
It is a basic survival mechanism. In the case of root crops, this can be a significant problem for root production. Once a turnip has bolted, roots become fibrous and inedible, and growth will slow or stop completely.
Why are my turnips dying?
Black rot, caused by the bacteria Xanthomonas campestris, can cause extreme loss of a turnip crop. The bacteria, which is spread by infected seed, debris and splashing water, spreads most rapidly during periods of warm, wet weather.
How often should I fertilize turnip greens?
Every 6 weeks
After planting: Every 6 weeks, you can apply an additional 2/3 cup of fertilizer per 25-foot row of turnips, at least 3 inches away from the plants, and mix it into the top layer of soil. Water well after fertilizing.
What is a good fertilizer for turnips?
Turnip gives a good response to organic fertilizers such as compost tea, blood and bone meal, and fish emulsion. If growing for greens, high nitrogen fertilizer will help produce deep, healthy green. A fertilizer that has high potassium will be better for the roots of the Turnip.
How often do you water turnips?
Turnips will germinate best in deeply watered soil. When growing, the roots need consistent moisture. Apply 1 inch of water a week if Mother Nature hasn’t done the job for you. In very sandy, fast-draining soil, apply up to 2 inches of water a week.
How late can you plant turnips for deer?
Turnips can be planted in late summer in northern climates or early fall in the southern states. Different turnip varieties produce different proportions of leaves and roots.
What are the signs of phosphorus deficiency?

- Poor appetite.
- Anemia.
- Muscle weakness.
- Bone pain.
- Bone disease (osteomalacia, rickets)
- Confusion.
- Increased susceptibility to infections.
What does phosphorus deficiency look like?
Phosphorus deficiency tends to inhibit or prevent shoot growth. Leaves turn dark, dull, blue-green, and may become pale in severe deficiency. Reddish, reddish-violet, or violet color develops from increased anthocyanin synthesis. Symptoms appear first on older parts of the plant.
What is the best natural source of phosphorus for plants?
Primary organically approved P sources are phosphate rock (PR), manure, and compost. Phosphate rock is most effective at supplying P in soils with low pH (less than 5.5) and low calcium concentrations.
Is Epsom salt high in phosphorus?
The nutrient value of Epsom salts is 0-0-0, meaning they contain no traces at all of nitrogen, phosphorus, or potassium. If you do choose to use Epsom salts on your plants, it’s important that you are aware that Epsom salts are not a substitute for fertilizer.
Do banana peels have phosphorus?
Banana peels contain lots of nutrients, including potassium, phosphorus, magnesium and calcium—all of which are needed for good plant growth.
