May Lawn & Garden To-Do List


Keep your lawn watered, especially if you applied fertilizer.

Lawns

    • Fertilize warm-season grasses (such as St. Augustine, zoysia, Bermuda, and centipede). Stop fertilizing cool-season grasses (such as fescue and bluegrass) to prevent heat damage.
    • Mowing season has begun! Set mower blades at 2”- 3” or higher for cool-season grasses. Warm-season grasses can be cut lower. Mow often and don’t cut more than half the blade at a time.


I keep rosemary by the kitchen door for cooking.

Vegetables and Herbs

    • Enjoy cool-season vegetables (such as spinach, carrots, and lettuce) before hot weather brings an end to the harvest.
    • Plant warm-season vegetables (such as tomatoes, peppers, and corn) after the last frost.
    • Plant successive crops of veggies every few weeks to extend your harvest.
    • Control weeds to reduce competition for water and nutrients.
    • Enjoy strawberry season while it lasts!
    • Address insect and disease problems as soon as you spot them.
    • Keep up with the harvest to encourage your plants to continue producing.
  • Don’t apply sprays to plants that are blooming or fruiting.


Houseplants will begin their spring growing season this month.

Houseplants

    • Once nighttime temperatures are above 50° F, put your houseplants outdoors on a shady porch so they can enjoy the summer heat while protected from strong sun and wind.
    • You can also bury potted houseplants up to the rim in planting beds to add texture.
    • Repot root bound houseplants.
  • If not repotting, remove the top inch of soil and replace it with fresh compost.


Nesting houses are an easy way to ensure hours of bird watching.

Cleanup and Maintenance

    • Make sure that lawns and gardens receive an inch of water per week. Hand water new transplants until they become established.
    • Get ready for bird nesting season!
    • Apply mulch under plants to keep the soil cool this summer.
    • Be on the lookout for lace bugs and aphids this month.
    • Examine conifers for the egg sacs of bagworms and remove before the eggs hatch.
    • Take photos of blooming plants you enjoy, so you’ll know what to buy for your own garden!
    • Try something new this year – visit a specialty plant nursery and explore the many varieties of plants available.
    • Don’t let weeds and vines get out of control – remove (or prune) them while they’re manageable.
    • Add water lilies to your pond when the water temperature reaches 70° F.
