July Pruning To Do List
Perennials & Roses
Prune back spent flower blossoms and leaves of hostas by clipping stems at the base of the plant. By deadheading roses and flowering perennials like salvia, coreopsis, yarrow and scabiosa, you will be rewarded with repeat blooms later this summer.
Herbs
If any of your basil is flowering, immediately snip off the tops of the plants which signals the plant to stop growing. Also, if you have a one to two foot basil plant, start harvesting and make pesto. The tastiest basil leaves are the young, tender leaves. By pruning back, you'll grow a fuller, bushier plant with more tasty leaves.
If your mint is looking scraggly, clip back to enjoy for mojitos or brew green tea, sugar and mint leaves for refreshing moroccan mint tea. You can cut back right to the roots and mint always finds a way to grow back.
Herbs like cilantro and dill tend to not perform well in the heat so enjoy them while they last then use the space to plant other herbs like rosemary or sage.
Coleus & Caladiums
If you've got flowers at the top of your coleus or white spaths on your caladium, while pretty, it's best to snip these off so your plant will continue to produce new leaves. With coleus, if your plant is starting to get too tall, go right ahead and cut it back to six to twelve inches and it will create a sturdier, bushy plant.
Pansies
What? You've still got pansies? These spring blooming plants hate the heat. It's okay to discard these stringy plants and replace with resilient plants like begonias which will bloom up until first frost.
Annuals
Snapdragons and dianthus prefer the cool weather but if you take the time to clip back and continue watering, snapdragons will bloom again in the fall. What's sold as "annual dianthus" will actually bloom again in the fall and will easily perennialize.
