June Gardening Tips for the Mountain West and High Plains
Snip off dead blooms from annuals and perennials. Removing faded blossoms encourages more flowers to form. Get flowering annuals on the fast track to a showstopping season by using bloom booster fertilizer.
Don't fertilize cool-season lawns during summer. Some grasses may go dormant during summer drought.
Feed tropical water lilies monthly through early fall to increase flower formation.
Continue fertilizing roses monthly to encourage more flowers to form.
Prune shrubs that have completed their bloom cycle.
Pinch the top inch of growth on garden mums near the end of the month.
Don't prune shrubs such as elderberries, viburnum, quince, cotoneaster, or currant after flowering unless you don't want fruit to form during summer.
Start slipping stakes into soil to keep flop-prone plants upright.
To avoid spearing dahlia tubers, add stakes at planting time.
