Read below for some things to consider when looking for a good multipurpose compost:
One thing that is easy to overlook when buying compost is the texture. You want something that isn’t too fine or too coarse, with the former tending to waterlog while the later needs constant watering.
A nice balance between the two is your best option – a nice crunchy texture that isn’t to fine or coarse works well. Cheaper products are usually stuffed with lots of bark and wood chunks which make the compost too thick.
The blend of ingredients varies significantly from product to product, so always be sure to check this before you buy to ensure it is suitable for your needs. Yes, multipurpose composts often have a similar blend of ingredients to ensure its suitable for various uses, there can be some notable differences that are worth remembering.
For example, many have a higher volume of fertilizer that feeds plants for longer while others can reduce the amount of watering by using ingredients that help store moisture.
Those with more fertilizer tend to last for several months before you need to add your own fertilizer to the plant, making them more convenient, although it often increases the price too. Similarly, if the compost can retain water more efficiently it’s very convenient but probably more expensive.
Multipurpose compost is traditionally made from a blend of ingredients that includes peat, green compost, lime, and wood/bark. It is worth noting that the processes for extracting peat are known to have a negative impact on the environment where they are sourced from, leading many to choose to avoid composts with peat content.
Thankfully, there are many peat-free composts that offer the same versatility without the harmful impact on the environment. Most of these work just as effectively as products with peat, so if you are an eco-conscious gardener be sure to look out for these.
Consider what plants you plan on growing and whether they require compost with a specific pH level. The pH levels can vary from each product so it always helps to check this and whether it meets any planting needs you may have.
For instance, seedlings tend to prefer more acidity, so if you are growing lots of seedlings then make sure that the compost pH is closer to acidic than alkaline.
Of course, the big benefit it being multipurpose means that its probably going to be fine for most plants even if the pH requirement is off a little – some plants may not thrive as much as they could with a specific compost but the multipurpose won’t kill them.
Make sure that you buy enough compost for your various needs throughout the garden! Many people make the mistake of not buying enough multipurpose compost because they forget it’s going to be used for anything and everything!
So, if you have lots of different tasks like planting seedlings, filling a raised bed, or adding pots to your patio, make sure you buy a high volume of compost – you’d be surprised how quickly it gets used.
