How to Choose Plant Food

With all of the potential options, selecting the perfect plant food for your home garden can be overly complicated, especially if you don’t know what to seek out and prioritise. The following sections explore key traits in quality products to help narrow down your choices. Once you know what features to look for, choosing the right solution for your specific garden life and preferences will be easy. 


Plant foods come in varying quantities to suit different-sized gardens and varying growing needs. Consider how much greenery you need to supply with nutrients inside and out, and select a product that gives you the required coverage. Otherwise, you may find you run out too quickly and leave some plants without a supplement. Or, you may have an excessive amount of the solution left over, which could be inconvenient if you are short on storage space. Just remember that many formulas come in a concentrated form, but some come ready to apply straight out of the container. 


The ingredients contained in plant food vary significantly from one product to the next. As a result, this makes them better suited to specific types of foliage and flowering greenery. While many formulas are designed for all-purpose applications, some are ideal for particular types of gardens. For example, some selections are created for indoor, potted flora, and others are more appealing for outdoor shrubs, lawns, and more. Organic solutions also open up potential and are highly sought after for growing vegetables and fruits. In addition, if you have small kids or pets in your home, you should prioritise an option that is pet and child friendly. 

Ease of Use

Plant food comes in various formats, some of which are easier to use than others. There are three main types of home fertiliser: granules, concentrated liquids, and spikes. The final form allows you to insert it into the soil and leave it to work its magic. Pellets are also straightforward and often just need to be sprinkled on the surface of the dirt. Fluid supplements are generally thought of as the most involved, but even so, they are not overly complicated to spread. They must be diluted and poured over the soil or sprayed on the leaves. Choose a product that will be easy and accessible for you to apply.


Finally, plant food must perform well and provide your greenery with the appropriate nutrients for enhanced growth and more. While these kinds of results may be hard to track at first, when you use a quality product, you will typically start to see results within a few weeks. Look for rapid upshoots, solid development, and lush colouring of the leaves and blooms to affirm that a particular fertiliser is working and improving the overall condition of your garden. 


The envii Seafeed Xtra Plant Food comes in various sizes and is easy to use for all-around convenience. Its organic formula has a high seaweed content and facilitates multipurpose application on various flowers, lawns, herbs, fruits, vegetables, and indoor greenery. The solution contains additional iron and amino acids and effectively improves development and yield. This product undergoes a superior harvesting and manufacturing process, leading to better quality and results down the line. Simply dilute the liquid with cold water and spray or water it onto the stems and leaves of your garden life to increase biological activity in the soil and encourage robust growth overall.
