3. Mulching
When in summer, perennial gardens that are densely packed will take care of most weeds. That said if you have a new garden or one that isn’t really filled up yet, getting some mulch is a good idea.
The mulch will help minimize the amount of weeds in your perennial garden to ensure that the soil retains its moisture — this is especially important if you don’t manually water your plants. Mulch isn’t just functional, it’s also aesthetically pleasing.
Think about how awesome your garden will look when it has some peanut shells or shredded bark laying around. If you don’t mulch, weeds could suck up all the moisture in your garden without you even knowing.
You might think that the perennials are doing fine based on your location, but later see them dying due to dried out soil. Mulching is definitely a worthwhile investment if you want to protect your flora.
