FAQs
When should you put compost on your garden?
Late autumn is considered as the best time to spread your compost over your garden bed, and cover it with a layer of winter mulch, such as shredded/chopped leaves and straw.
By spring, soil organisms will have broken the compost down into the soil & made them biologically active, thus helping build up richer fertile soil.
Also, you can dig in soil amendments roughly 14 days before the spring planting time.
Can you have too much compost in your garden?
Compost provides soils and gardens with both organic matter & natural nutrients essential for plant growth, but too much of it could become toxic.
Can I plant directly into compost?
Compost mixed with topsoil & water can do the magic, as it aids in moisture retention in sandy soil and good drainage in heavy solid soil. Therefore, planting directly in pure compost may sound tempting but is not the best planting method at all.
Is compost or fertilizer better?
What makes compost and fertilizer different from each other? While the former enhances the natural soil & promote the growth of healthy microbe to create a favorable environment for plants, the latter works to feed them.
To create your own compost, the plant remnants added to the mixture must be void of soil-borne pathogens which might cause an infestation in healthy plants. Also, expect to wait for one month or two for the decomposed organic matter to fully break down and great composting efforts’ results witnessed.
Though most types of fertilizers can effectively and quickly amend the soil for healthy plants’ growth, some might contain synthetic chemicals while others might overload the garden beds with nutrients.
What is the best ratio of compost to soil?
Mix equal parts sharp sand, compost, and garden soil for the classic soil-based mix. Also, you can cover your perennial flower gardens with a compost layer no thicker than 1/4 to 1/2 inch.
Sandy soil should incorporate 2 parts compost and 1 part soil for the addition of organic matter essential for your veggies & flowers to thrive. If soil in the raised bed is heavy clay, lighten the soil by perlite instead of sand.
Is compost good for vegetable garden?
Compost is good for vegetable gardens. However, since all of the decomposed remains of organic materials will contribute to improving crop yield, you should not cover your vegetable garden with a thick layer of it.
Ideally, spread a layer of 1 inch or two of compost over your soil once in early spring and again after the harvesting season.
Conclusion
Now, there you’ve got the list of the best compost for garden! By purchasing one of the models above, you're investing in not only the veggies but also your health & body.
