- Continue sidedressing your garden vegetables.
- July is the month we recommend giving landscape plants a second (last) feeding of fertilizer. Take soil samples from your lawn areas for testing. Soil boxes are available at the N.C. Cooperative Extension, Alexander County Center.
- Plants of brussel sprouts and collards can be set out in mid-July.
- You can begin your fall vegetable garden this month. Plant beans, carrots, brussels sprouts, and tomatoes in July.
- Start broccoli, cabbage, and cauliflower plants in peat pots to transplant into the vegetable garden in mid-August.
- Begin repotting overgrown houseplants.
- Prune “bleeder” trees like maple, dogwood, birch, and elm this month.
- Prune the fruiting canes of raspberry and blackberry plants after harvest is over. Cut canes at ground level.
- Prune off dieback limbs on hybrid rhododendron, azalea, mountain laurel, and blueberry.
- Trim hedges as needed.
- Continue pruning white pines and narrowleaf evergreens like juniper early in the month.
- Remove faded flowers on flowering perennials to encourage a second flowering.
- Pinch your chrysanthemums the first week only!
- Do NOT prune spring-flowering shrubs now.
- Spray for Japanese beetles as needed.
- Spray your tree fruits and bunch grapes on a regular basis.
- Spray the following vegetables if insects are observed: cucumber (cucumber beetle), squash (aphids), tomato and eggplant (flea beetle).
- Spray woody weeds like poison ivy, honeysuckle, and kudzu with a recommended herbicide.
- Remember to change direction when moving your lawn. Travel north to south on one mowing and east to west on the next cutting.
- Maintain 3-inch mowing height.
- This month is still a great time to take semi-hardwood cuttings of azaleas, holly, rhododendron and many other shrubs.
- July is an ideal time to divide and transplant your iris and daylilies.
- July is a good month to see if and where your home can use some additional shade trees.
- Blossom-end rot may be seen on tomatoes this month. Two factors – too little water and too little lime in the soil – may be the reason. In dry weather, both your vegetable garden and landscape plants will benefit from a good soaking watering. Slow watering will penetrate the root zone better. Apply 1 inch of water early in the day.
