If the hydrangea does not wake up from hibernation and produces no or hardly any fresh shoots, this can have several reasons. Budding until mid-April is not yet unusual, but the following options are generally possible.
Both the species and the variety of a hy drangea determine the time at which it sprouts. The warmer and sunnier it was until April, the faster a hy Drangea will grow. If the pH value of the soil has changed or was in an unfavorable range from the start of planting, hydrangleas react sensitively. The plants prefer a rather acidic soil with a pH value between 4 and 6. If none of the hyDrangea shoots show a fresh green color when the bark is scratched, the entire plant may be frostbitten and need to be replaced. If only the leaves have turned brown, no action is necessary. You can find even more exciting garden topics in the regular newsletter from our partner 24garten.de.
