Buying guide to best moss killer
Moss is one of the toughest things to get out of the garden. Since it thrives on damp conditions, moss spreads rapidly in gardens and lawns. It is a plant that contains green chlorophyll and covers other plants quickly in the form of a thin mossy film.
To get most of the moss out of your garden and lawn, it is crucial to understand how moss reproduces and grows in the first place. It is possible to control and eradicate the moss by making changes in the soil, nutrients through fertilizers, or water supply. Moss, when left unchecked can causes diseases to plants and soil beds and can weaken the surrounding natural environment. Mosses can also multiply on hard surfaces like roof tiles, planting beds, and drives.
When is the right time to kill moss?
It is challenging to kill moss during the rainy or summer seasons since moss thrives in these climatic conditions. The right seasons to kill moss and save your plants and flower beds are late winter to early spring. You should start your moss treatment as soon as you realize that the winter is waning. If left unchecked, the moss will overrun your lawn, garden, pots, and flowering beds.
The moss killer from Premium is an iron sulphate packed product that kills moss while simultaneously fertilizing your lawn.

The tub is designed keeping in mind the reuse that it will undergo, and so comes equipped with a resealable clip-top plastic tub.
The product can be used directly in its dry condition when mixed with soil, or diluted with water and sprayed directly on the moss with a sprayer or a watering can. The results from the Premium Iron Sulphate Moss Killer start showing within a week.
