June Gardening Calendar 2025

June is the time of year to trim your Big Leaf Hydrangea, Oak Leaf Hydrangea, and Gardenia after blooming. After trimming, use an Azalea and Hydrangea fertilizer and add a new layer of mulch for the summer and fall months. The flower buds are set in the fall months for summer months blooming.

Your cool season vegetables have already started to bolt (bloom), which alerts the gardener the season is over for cool season vegetables. You can either pull out the vegetables or till them into the soil to enrich and add nutrients to the soil.

We can start thinking about planting winter squash, pumpkins, gourds, okra, and southern peas.

There is still time to plant heat tolerant vegetables tomatoes, peppers, eggplants, and watermelons. These I thought are worth mentioning to try in your garden:

Malabar Spinach is a heat tolerant alternative to traditional spinach and grows as a vine. The leaves in salads are fleshy and have a peppery, citrus taste when used fresh. When cooked Malabar spinach taste just like traditional spinach. Make sure the plant is always well watered. You can use the leaves fresh, stir-fry, steamed or boiled.

Okra enjoys the heat. The spineless varieties are recommended because of the spines on the plant and okra. Even with the spineless varieties it is recommended to wear gloves and long sleeves when harvesting the okra. Some of the varieties recommended are Clemson Spineless 80, most popular, Emerald, White Velvet, Cajun Delight.

Sweet Potatoes can be grown in a container, such as potato grow bags, whiskey barrels, or a very large container. You can harvest the tubers, sweet potatoes in about 4 months.

Summer Yellow Squash is very prolific grower and producer and enjoy the summer heat. In the summer would have summer squash several times during the summer. Yummy. Try cooking steamed or boiled with sliced onions, if you like onions.

Peppers, hot or sweet. There are many varieties of green, yellow, orange, red. All colors love the heat. In areas that have extremely high temperature during the summer months you may need to give some afternoon shade to prevent flower drop.

Bush Beans are easy to grow and do not require staking. Provider, Blue Lake 274, Contender are just a few varieties to grow this summer.

Butterhead Lettuce is one of the lettuces that will take the summer heat. Water deeply and mulch heavily.

It is always a good idea to monitor your garden for insects and diseases. Early detection is the key. When you are uncertain of the insect or disease, take a sample to your local garden center or nursery.

Fertilize tomatoes every two weeks with a calcium enriched fertilizer. The calcium will be listed on the label.

In June, there are numerous perennials in stock at your local garden center. A perennial is defined as a plant lasting more than two years. Asclepias (milkweed) is one great perennial that is gaining popularity. Milkweed is the host and nectar plant of the Monarch Butterfly. Last year the Monarch Butterfly was put on the endangered species list. As gardeners we can start incorporating Milkweed (Asclepias) into our gardens. Asclepias do extremely wonderful in containers for the apartment gardeners. We have to act now and quickly. Buy your plants or seeds now. The Monarchs need our help.

Color annuals and Tropicals are blooming brightly at your local garden center. Start thinking about starting your container gardens and color bowls to place around your deck, patio, or outdoor living area. Tropicals know how to beat the heat of summer and will bloom continuously till first frost.
