Never leave bare soil in the garden; bare dirt invites weeds. Regardless of the sort of garden you are cultivating, cover exposed soil with mulch or plants to prevent weed growth. Utilize bark mulch or a comparable substance in a shrub or perennial garden with plants spaced to allow for development.
To make a live mulch in my vegetable garden, I use shredded leaves, straw mulch, or interplanting. Interplanting is the practice of planting many types of crops in the same area. Between slower-growing plants such as tomatoes and broccoli, I place fast-growing plants such as arugula and leaf lettuce. Before the slower-growing plants require the room, the greens are picked.
I grow my vegetables extensively as well. High-intensity planting involves closely spacing seeds or transplants. You don’t want them to compete for sunlight, water, and nutrients, so consult the seed packages for the appropriate spacing. However, you want them to develop thickly with good root systems in order to suffocate weeds.
How can I prevent weed growth in my flower beds?
Using Cardboard and Mulch to Prevent Weeds in Flower Beds – I have discovered that preparing your garden beds with cardboard and several inches of mulch is the most effective approach to keep weeds out of a fresh bed. It not only suffocates existing weeds, but also provides a physical barrier to inhibit future weed development.
Effective barricade requires a consistent application to the soil’s surface. Use 2.5 to 5.94 pounds per 1000 square feet. You must measure your treatment area beforehand. Always read the label to determine the correct application and dosage rates. Apply the Barricade to the Flower Bed Spread the barrier evenly using a hand-held granule spreader for a homogeneous application. 
Exists a natural herbicide?
Ingredients for homemade weed killer – The most effective DIY solution consists of white vinegar, salt, and liquid dish detergent. Each of these compounds has unique qualities that work together to eliminate weeds. Salt and vinegar both contain acetic acid, which acts to dehydrate and destroy the plants.
In the meantime, the dish soap decreases the surface tension of the combination, allowing the liquid to penetrate the leaves’ pores rather than lingering harmlessly on the surface. Mix one gallon of white vinegar, one cup of salt, and one tablespoon of dish soap to make a good supply of this man-made mixture.
Ensure perfect mixing, then pour the fluid into a spray container for convenient application. You can store the bottle at home for future use. The optimal time to apply weed killer is during the sunniest portion of the day, as the sun and heat aid to dry out and kill the weeds.
