A magnolia's appearance changes enough through the year that one photograph is a poor record of its growing cycle. Photograph the whole plant and several representative buds before they open, during flowering and as foliage develops.
Keep the botanical or cultivar name with the images. Different magnolias do not all follow the same sequence, so avoid turning one tree's dates into a rule for the whole group.
Include the site in the record
Note the position, exposure and any major weather events. A sheltered tree beside a warm wall may differ from another plant of the same name in an open garden.
If buds fail to open normally, record their condition rather than removing every affected part before inspection. Check whether the problem is widespread or limited to one branch.
The record can also help you decide when maintenance is appropriate. Before pruning, moving or feeding the plant, consult guidance for the identified magnolia and its present stage. A dated sequence of your own tree is a useful companion to that guidance, especially when a generic flowering calendar does not match what you see.
The RHS magnolia guide describes different species flowering from early spring to late summer and notes that frost can damage early flowers. Include weather and the plant’s name in the photo record instead of using one tree’s calendar for all magnolias.
