Almond trees, known botanically as Prunus dulcis, are grown for their spring flowers and fall fruits or nuts. Almond trees do not require regular annual pruning to encourage fruit development as some nut and fruit trees do. They will, however, benefit from occasional trimming throughout the growing season as needed to keep the tree healthy and tidy looking.
Remove broken, diseased, split or otherwise compromised almond branches or foliage when you see them throughout the spring, summer and fall. Cut back to the point of healthy wood to just 1/4 inch above a bud or leaf axil. Remove only as much tissue necessary to clear the damage; excessive pruning will remove fruiting buds.
Remove any interior branches that are abrading one another to prevent an entry point for disease. Cut one or both of the branches in question down to the parent branch or at least so they are no longer touching or growing in the same path.
Trim the branch tips and under canopy of your almond tree in the spring after bloom when growing it solely as a flowering ornamental and nut loss is not a concern. Trim the canopy into the desired shape and size with loppers or shears following the natural form of the canopy or a symmetrical topiary shape.
Pull all of the cuttings from the canopy and chip and compost, dry and then burn or recycle them.
