What is the best thing to put in the bottom of a large planter?
Repurposed, Lightweight Planter Fillers These materials help save on soil while reducing waste: Plastic water and soda bottles. Unused nursery pots. Non-dissolvable packing peanuts. Using lightweight fillers like plastic milk jugs or packing peanuts will save space and reduce the amount of potting soil needed. The balance between size and type of plants is important for optimal growth and root depth.Topsoil is best used for outdoor projects where the root systems have space to expand rather than being confined to a container. Using topsoil for plants in pots will mean that your plant won’t get the nutrients it needs to grow and will more than likely die sooner than expected.Garden soils are typically intended for use in the ground and contain minerals and organic matter. They are not a good choice for containers because the soil can quickly become compacted and waterlogged, reducing air space around the roots. This can lead to poor or stunted growth.
Should I put anything in the bottom of my planter?
Putting rocks or gravel in the bottom of a planter is generally unnecessary, as this practice can impede drainage rather than improve it. Adding a layer of drainage material such as gravel or pebbles will help guide excess water away from the roots of your plants minimising the changes of rot. This can also help with air circulation which is essential in maintaining plant health.
Can you put soil directly into a planter?
There is nothing inherently wrong with treating a big planter in the same way as you would a small planter, by filling the entire pot with potting soil. There are purist gardeners who stand by this view. From their perspective, there can never be too much potting soil for the plant roots to enjoy. Best Practices for Filling Large Planters Some gardening experts recommend using only soil to give plants maximum root space, and others caution that sand can create an unsuitable growing environment. However, most agree that organic matter will eventually break down, becoming soil rather than remaining a filler.
Why put cardboard in the bottom of a planter?
You can line the bottom of your raised garden bed with cardboard and newspaper to block out weeds or act as a barrier against rhizomatous, weedy or invasive plants. While some may opt for landscape fabric, cardboard is a more cost-effective option. Create or extend existing beds by smothering grass and/or weeds with a double layer of cardboard, weighted down with mulch. Weight the cardboard down by applying a thick mulch (10-15cm of organic matter) on top. If you want to plant up the bed straight away, wet the cardboard before adding the mulch on top.
What is the best fertilizer for plants?
Most gardeners should use a complete fertilizer with twice as much phosphorus as nitrogen or potassium. An example would be 10-20-10 or 12-24-12. These fertilizers usually are easy to find. Some soils contain enough potassium for good plant growth and don’t need more. Nitrogen helps produce green leaves and stems, phosphorus helps produce root development, and potassium helps the plant withstand stress from heat or cold. A good all-purpose fertilizer would be a 10-10-10 NPK (nitrogen, phosphorus, and potassium). This type of fertilizer will work well for most plants and soil types.The best fertilizer for plants largely depends on their specific needs. Generally, a balanced fertilizer containing equal parts nitrogen, phosphorus, and potassium (NPK) can provide essential nutrients for overall growth. However, it’s crucial to consider factors such as soil type, plant species, and stage of growth.High-nitrogen fertilizers are known for causing huge growth in plants, which is why many types are rich in nitrogen or include it as the main component. Fertilizers high in nitrogen will also restore bright green hues to your foliage.
