Asparagus Fertilizer Requirements
A general-purpose 10-10-10 NPK vegetable fertilizer is ideal for asparagus.
Since asparagus is a fast-growing perennial that requires a balanced fertilizer. You’ll want to use a quality organic fertilizer that has a relatively even mix of nitrogen, phosphorus, and potassium along with essential micronutrients.
When To Fertilize Your Asparagus
The best time to fertilize asparagus is in the early spring when new shoots start growing vigorously. Apply fertilizer before the soil warms up too much (usually around April).
You can also apply fertilizer in the summer once your plants reach full maturity at 3-years of age.
To fertilize your asparagus, you should apply fertilizer at a rate of 2 to 2.5 pounds per 100 sq/ft in the springtime.
How Often Should You Fertilize Asparagus
You should fertilize asparagus once in the spring, and again during the summer for mature plants.
It’s also a good idea to fertilize periodically throughout the month of April especially if you have heavy rains to help counter nutrient runoff.
What Is A Good Fertilizer for Asparagus
Asparagus is a popular vegetable to grow at home. It can be grown from seed, but it’s easier to buy a plant and transplant it into your garden. Once you have an asparagus bed established, there are a few different fertilizers that work well for this vegetable crop. The best fertilizer for asparagus may depend on what type of soil you have in your area. However, in general, mixing compost or manure into most soils will provide good results in combination with a good balanced organic fertilizer.
Why Is My Asparagus Dying
Why Is My Asparagus Plant Turning Yellow
The most common reason for an asparagus plant turning yellow is lack of light. A secondary reason could be a lack of nitrogen, which makes the chlorophyll in the plant less abundant.
So if the problem isn’t one or both of these things, it’s most likely something else. In that case, check your root crown to see whether it’s exposed (e.g., when replanting) and always make sure there’s enough soil surrounding your asparagus plant to keep water or wind from blowing away loose dirt; this will help stabilize the root system and enable roots to absorb moisture more easily.
Why Is My Asparagus Plant Turning Brown
Root rot due to overwatering is one of the more common reasons asparagus plants turn brown but underwatering can be a cause as well.
Underwatering causes your plant’s root system to shrink and pull back from the soil, which leaves it unable to take up water or nutrients for sustenance, causing brown leaf tips or leaf drop.
Asparagus ferns need about an inch of water per week. If they’ve been getting less than this–they may have dried out – so give them some extra water and see if they bounce back.
Why Is My Asparagus Plant Turning White
If your Asparagus is not receiving enough light, it will turn white since it will be unable to produce chlorophyll.
Why Is My Asparagus Turning Purple
There are two possible reasons why your asparagus is turning purple – it could either be a naturally occurring purple variety or the plant might not be getting enough phosphorus.
Why Is My Asparagus Plant Not Growing
- Asparagus plants need a lot of sun
- If the asparagus plant is in soil, it needs to be watered frequently
- Asparagus plants do not like being transplanted from one place to another
- Make sure that the asparagus plant has been planted correctly – make sure that it’s straight and not leaning over or falling over
