Before hitting your favorite store and transforming your garden into a little paradise, it’s important to brace yourself with knowledge on the flowers you want to invest in.
Online stores are filled with millions of beautiful flowers that might leave you confused and spoilt for choices and end up with the wrong decisions.
To avoid all these, you need to equip yourself with the right information on what flowers are best for your garden.
Remember, flowers behave differently depending on the season, sun exposure, and type of soil. We have flowers that thrive well in full sun, while others will only work well in shades or just light. Others will do well in winter than they will in summer.
Additionally, it’s important to note that some flowers have a longer lifespan than others. For instance, perennial flowers can stay up to two years with lesser costs. These types of flowers will not only help you save cost but also attract butterflies, bees, and hummingbirds with their stunning blooms.
