Tips to Keep Long-Blooming Perennials in Flower
Just like people, plants need the right care to perform their best. Get the most blooms from your perennials by following the instructions on Monrovia.com or the plant’s tag.
Location
Plant your perennials in the correct spot. If they need full sun, make sure they get approximately 6 hours a day of sunshine. The same goes for shade. If it is recommended that your plant needs a break from the heat and light, find a spot that fits. Pay attention to the soil type, as well. Plants grow best if their roots are happy. Most perennials do best in soil that drains well. If you have challenging soil conditions select varieties that can handle those soil types. Additionally, try amending the soil liberally with organic matter (such as compost). Challenging soil includes things such as clay, compacted soil, or sand.
Food and Water
With perennials, you can have too much of a good thing. Overwatering and overfertilizing can lead to lush foliage and fewer blooms. An overabundance of care can also leave your plants more susceptible to attack from insects and disease. This is because of the soft growth. Follow the recommended watering and feeding instructions to get the most out of your perennials.
Maintenance
Deadheading — the act of removing old flowers after they fade — helps keep many reblooming perennials in bloom longer. Some perennial plants also prefer to be divided every few years to keep them lush and healthy. If a perennial needs dividing and is too crowded, it will bloom less, and grow less vigorously overall.
