You can plant hydrangeas in the spring or fall. Prepare the soil by adding organic matter if necessary. Plant in a hole that is as deep as the root bulb and 2-3 times as wide to give the roots enough room to expand. Leave space of 3-8 inches between plants. Be sure to loosen the roots before planting. Fill up the hole with soil and water very well.
Hydrangeas thrive best in partial moist and well drained organic rich soil (moist but not wet). So make sure you water them well without overdoing it. You can add mulch to keep the soil moist.
Hydrangeas like the sun and need it to grow. Make certain that you plant your plants somewhere that they’ll get about 6 hours of sunlight every single day. Choose a place that gets sun in the morning and afternoon, but has shade in the late afternoon to prevent wilting and bleached leave in hot summer temperature.
How and when you prune depends on the type of hydrangea you are growing. Most of them don’t really need major pruning other than removing dead stems and old flowers to keep the plant tidy.
While there can be many pests that will attack these plants, two of the biggest offenders tend to be snails and slugs. Acting quickly before the pests spread and take over is key.
Cercospora is a type of disease that produces leaf spots on the bottom of the leaves that are often purple or brown in color. You can try to stop this disease from happening by not watering the leaves whenever you’re watering the plant. Try to water at the base of the plant instead.
There are several factors that can cause your hydrangea to not bloom. It could be that you mistakingly removed a stem that would have bloomed or that you pruned at the wrong time. It could also be that it’s not getting enough sunlight or that frost may have damaged the flower buds. Another factor is over-fertilization.
Yes, they do. This is why they’re one of the more popular planting choices. Once you plant them and get them to start growing, they should come back every year without hardly any effort or time from you..
