4 Frequently Asked Questions
#1. How Do I Apply Mulch?
Applying mulch around your Onions plants can be a great way to promote healthy growth, but if not done appropriately it can also stunt your Onions’ productivity.
When applying mulch to your Onions plants you should:
- First, weed the soil where you will be applying mulch
- Next, lay down approximately 6 inches worth of thickness of newspaper. This will prevent excess light that can potentially promote weed growth.
- Next, apply 4 to 6 inches of mulch around your Onions plants to discourage weeds, retain moisture, and
#2. What are the Different Types of Onions Mulch?
There are two different types of mulch you can purchase for your Onions plants. You can buy organic mulch which will provide benefits to your garden and inorganic that typically lasts longer.
Below, are the types of organic mulch you should use for your Onions plants:
Compost is made of organic kitchen and yard waste. Using compost will not only protect your Onions plants from weeds but provide nutrients over a long period of time.
When using compost it is recommended that you reapply it yearly to provide the greatest benefit to your plants and garden.
B) Wood Chips
Wood Chips are the most common organic material used for Onions plant mulch.
This type of mulch comes in numerous types of colors and varieties.
It is another type of mulch that provides great nutrition to your garden and plants as it breaks down. It should be replenished yearly though.
C) Straw (Hay)
Straw is an organic material that is clean, light, and easily decomposes.
Straw is a great way to immediately add nutrients to your Onions plant. Typically, you will need to replace straw monthly or add an extra few inches of layering if you want it to last longer.
Best of all, you should use straw if you want to mulch your Onions plant, but also protect your seeds from wind and rain.
D) Pine Needles
If you are interested in a mulch that breaks down slower and increases the acidity of your Onions plant then you should use pine needles.
Pine Needles are a great way to add nutrients into your Onions plant and will not wash away during a wind or heavy rain.
Leaves are the best type of organic material if you are making mulch yourself.
This type of mulch is easy to accumulate, decomposes faster than most other organic materials, and replenishes nutrients into your Onions plant.
Below, are the different types of inorganic material you can use to mulch your Onions plant:
A) Black Plastic
Black Plastic is one of the best ways to mulch your Onions plant to prevent weeds.
When using black plastic you will need to monitor its durability as the sun can quickly break it down.
In addition, black plastic can retain heat in your Onions plant but should be monitored because if it gets too hot it can destroy the roots of your plants.
A newspaper is another great way to mulch your Onions plants.
It is recommended to wet down your newspaper before placing it on the soil.
While newspaper will need to be replaced after one season, it does allow for plants to penetrate through it for greater access to sunlight and pollinators.
C). Landscape Fabric
Landscape Fabric is a great type of inorganic material that can be used to prevent weeds when mulching.
This is a great type of material that can be placed under rocks or gravel and can help prevent stones from sinking into the ground.
