Fig 5. Seasonal soil moisture data measured in A) 2016 and B) 2017.

From the ten plots, five measurements of soil moisture were taken per measurement date. For graphical representation, data were grouped by plot and date and averaged into single, weekly values for each plot. Boxplots represent the minimum, first quartile, median, mean (◇), third quartile, and maximum calculated on the weekly averages across plots. Dashed vertical lines highlight bud type transition, the time at which chasmogamous budding ceased and the first cleistogamous buds were observed.
