What to Do in Your Garden in July
It’s officially summer, meaning the heat is here in full force! I set my watering can by the door as a reminder to water my plants. A few years back, when I first started growing an interest in gardening, I learned the hard way that you have to water your plants regularly because of the Mississippi heat. Don’t be like young Michaela. Always water your plants!
Here are a few things that you can do in your yard and garden during the month of July.
Planting
- Plant pumpkin seeds for a Halloween harvest.
- Use portulaca or marigolds to fill in bare spots in your flower beds.
- Root cuttings of azaleas, boxwoods, camellias, gardenias, hollies, and poinsettias in coarse sand. Cuttings should be 4–6 inches from new growth with lower leaves removed.
- Plant now for color in the fall: marigold, zinnia, celosia, and Joseph’s coat.
- You can still plant daylilies.
- Start cuttings for house plants: ivy, wandering Jew, philodendron, and begonia.
- Plant fall vegetables: cabbage, parsley, and collards.
Fertilizing
- Do not fertilize camellias after July 1.
- Fertilize chrysanthemums around July 15.
- Fertilize all of the garden as you did in March.
- Fertilize lawns with a well-balanced fertilizer.
Pruning
- Remove faded flowers from crape myrtles to encourage a second blooming.
- Pinch back mums before July 15.
- Cut back broken or withered fern fronds. New growth will appear for fall gardens.
- Pick all vegetables regularly to ensure continued bearing.
- When cutting boxwood into a hedge, make sure the base is wider than the top to allow sunlight to reach the plants’ bases.
- Remove dead limbs from trees and shrubs.
- Prune roses to encourage fall blooms.
- Remove flowers from basil and cut mint to encourage new shoots.
Mulch
- Check mulch on azaleas and camellias. Mulch should be at least 2 inches thick.
- Keep zinnias and mums mulched to conserve moisture and reduce weeds.
Miscellaneous
- Water azaleas well because they are setting flower buds now.
- Cut grass at 2.5–3 inches during hot weather.
- Water the whole garden deeply once a week.
Home Accent
-
Never leave house plants in a closed home when you’re away for vacation. Either water and place them under a shady tree or have a friendly neighbor come in and water them for you.
