June Lawn and Garden Tips 2021


June lawn and garden tips for Northeast Florida start with the recognition that Summer begins on June 20. This is also the Summer Solstice, the longest day of the year as the Sun is at its highest point in the sky. June 1 is the first day of hurricane season. Rainfall totals for Jacksonville between January and June 2021 were 17”, which is one inch above average. However, May was a dry month with less than a half-inch of rainfall, with most of the monthly totals coming in February and April. As a result, the soil is dry and irrigation and hand watering crucial. Fortunately, the chance of rain increases each day of June historically to the greatest daily likelihood coming at the end of July. June is typically a wet month averaging nearly six inches of rainfall, with last year’s total being 8.9 inches. In June 2012, Jacksonville received over 21 inches of rain, with 12 inches of it associated with Tropical Storm Debby. Rain is good, but not too much.

June’s climate in Northeast Florida is typically prime time for planting a wide assortment of warmth and full sun-loving flowering plants and shrubs. Rising soil and air temperatures of spring and early summer make for good conditions for planting palms and drought-tolerant choices, including African Iris, bromeliads, bulbine, crotons, figs, fountain grass, lantana, agaves, birds of paradise, junipers, and fruit trees. Vegetables for planting directly in the ground in June include okra, peas, squash, spinach, and sweet potatoes as the heat becomes too much for most cooler season vegetables. Remember to water new landscape plants daily for the first month, which is an allowable exception to the twice per week watering restrictions for the region.


Remember the five D’s of pruning, pruning a plant anytime it is dead, dying, damaged, disfigured, or showing signs of diseased wood. Shrubs that bloom in spring typically set their blooms on old wood from the prior season, whereas summer-blooming shrubs typically set blooms in spring on new growth from the same year. Thus, trim your spring bloomers immediately after their flowers bloom to allow for the preservation of buds for next year. Prune your summer bloomers in late winter or early spring to encourage new growth before bud setting. Ask Earth Works garden center staff for help with your specific plant pruning requirements.


It is essential to match the nutrient needs of your landscape and house plants with the appropriate NPK (Nitrogen, phosphorus & potassium) provided by various fertilizers. For example, balanced fertilizer such as 10-10-10 has an equal percentage of nitrogen for green leaf development, phosphorus and potassium for root growth, and setting blooms and fruit. Soil testing provides a baseline of information for knowing your plant’s nutrient needs, and testing is free in Northeast Florida at the University of Florida IFAS Extension Office. Learn more about their services in our blog “Soil Testing in Northeast Florida.”

Long-standing recommendations were to fertilize your lawn in spring, followed by an additional application in summer and then a winterizing fertilizer application which prepares the sod heading into winter dormancy. However, in 2007 the Florida Department of Agriculture and Consumer Services (FDACS) passed the Urban Turf Fertilizer Rule that reduces the amount of phosphorus and potassium allowed for release during lawn fertilization to negligible percentages, basically defined as low or no phosphorus and nitrogen. Dozens of counties have rules more strict than the state rule prohibiting nitrogen and phosphorus entirely between June 1 and Sept 30 due to the increasing frequency of devastating algae blooms. Duval County does not.

Most of your houseplants do well with monthly liquid fertilization during their growing season. However, because of the wide assortment of plants in the typical landscape, please research their nutritional needs and consider using slow-release fertilizers. In addition, create setbacks around water bodies and pathways to storm drains to avoid fertilizer pollution. Earth Works lawn care division provides aeration and top dressing services to replenish lawn nutrients that reduce your fertilization and watering needs.

The warmest months of the year are times you expect to enjoy your pond and water garden the most, but anxiety arrives if your fish are suffering as a result of a poorly designed & equipped, dirty, overstocked pond that all contribute to low dissolved oxygen. There you are trying to enjoy some time pondside as that Summer warmth cooks the O2 out when the fish need it most. Supplemental aeration helps during these times of Summer by raising the dissolved oxygen levels. Learn more in our blog “Low Dissolved Oxygen: Koi Summer.”


June’s heat and moisture make for good conditions for and an explosion of lawn and garden pest species. Chinch bugs, sod webworms, grubs, mole crickets, and fungus are a few of the species attacking the lawn while aphids, thrips, whitefly, leafhoppers, leaf miners, and leafrollers go after the flower beds, trees, and shrubs. The Earth Works lawn care department has a seasonal pre and post-emergent pesticide treatment program and provides instant quotes for all available services.
