Avoid buying a plant in bloom. When you buy a new plant and move it to your home or garden, it requires sufficient amount of energy to adjust to new conditions especially when you are transplanting it. If the plant is already in bloom, it would continue to finish the blooming cycle instead of establishing itself resulting in poor health. If you have to buy a blooming plant, it is better to nip the buds and blooms so that that plant can use its energies to acclimatize itself. Once established in its new place, the plant would produce healthy foliage and prolific blooms in the next blooming season.
