June Gardening Tips

Thursday, May 28, 2020


  • Mowing at the correct height and frequency is one of the most important things you can do keep your lawn thick and weed free. Different turf types have different ideal mowing heights. Centipede, bermuda and zoysia lawns are best kept at 1″ to 1 1/2″.  St. Augustine lawns need to mowed at 3″ to 4″ high.

  • Seeds of centipede, bermuda, and certain varieties of zoysia can be sown in June but need frequent watering to germinate. Do not allow grass seed to dry out after being sown. St. Augustine grass cannot be established by seed.

Trees, Shrubs and Flowers

  • Plant annual flowers in tubs or large containers for the porch or terrace. Make sure there are holes in the container's bottom to provide good drainage.

  • Remove dead flowers from bedding plants to get more flowering. Removing the dead flowers or "deadheading" prevents the plants from not flowering and going to seed and before summer is over.


Fruit, Vegetables and Herbs

  • Remember to fertilize your tomatoes as they are growing.  Fertilize with 2-3 tablespoons per plant after plant has started to set fruit and 4-6 weeks thereafter throughout the growing season.  Use 8-8-8 and 10-10-10.  Keep fertilizer 4-6" from the plant's stem to avoid fertilizer burn.



  • Plant sweet potato slips in June for fall harvest.
