Summer Garden Tasks

By: Jennifer LaMontagne – Horticulturist – Bloch’s Farm – Green Lake, WI

June has arrived, and the warm summer days are a perfect time to get out in the garden. By keeping up with summer gardening maintenance tasks a little at a time, you can reap the rewards with healthy and beautiful plants. Here are some suggestions for work that can be completed from June to August to keep your gardens in tip top shape!

            Removing weeds before they go to seed is important and more easily accomplished by removing them just as they emerge. Your garden plants compete with weeds for water and nutrients, so weed removal allows plants to benefit much more from the available resources. Keep your plants watered and fertilized so they grow to fill spaces instead of the weeds. Mulching around the base of trees, shrubs, and flowers helps them retain water. Proper watering is essential during hot, dry conditions throughout summer. 

Continue to fertilize annuals and perennials throughout the summer season, taking caution to avoid fertilizing if your plant is too stressed from the heat. As vining plants start to grow taller, it’s a good idea to provide support with a stake or trellis. Continue to sow in succession, seeds such as beans and leafy greens to produce a continued harvest. In mid-summer, you can start to sow seeds for your fall vegetable garden. Plant collards, kale, spinach, and root vegetables such as carrots, beets, and turnips. 

It is a good time to dig up and divide daylilies and irises once they have finished blooming. Prune suckers from trees right away because they take energy away from the main tree. Lightly prune spring-flowering shrubs in summer once they have finished blooming. For example, lilac bushes need to be pruned soon after their flowers are spent. Like other bushes that bloom on mature wood, lilacs set the buds for next season almost immediately after the last blossom has faded. Other examples of shrubs that bloom on old wood are bigleaf hydrangea, forsythia, weigela, and azalea. 

As herbs continue to grow, pinching them back will help create a full, lush plant. Remove spent flowers on annuals and perennials to encourage new growth and reduce chances of diseases and pests. Monitor and protect plants from pests and diseases. It’s a good idea to cover or set up scare devices to keep birds off of fruit trees and shrubs.
