What to Plant in July

We recommend most plants be planted in the fall or spring.  However, if you must plant during the summer months watering may need to be more frequent and you must be diligent about observing your newly planted plants for signs of water stress.

Many cacti and warm-season succulents can still be planted in the summer. When transplanting cacti and succulents, mark either the south or west side and plant facing the orientation you marked to avoid the burning of tender tissues. Most nurseries will mark the side of the container to help you determine proper planting orientation.

However, if the original orientation is not known, newly planted cacti and succulents need to be covered with shade cloth if the plant surface appears to yellow or pale suddenly. Use a shade cloth rated between 30-60% as anything higher will block most of the sunlight and will not be suitable for your cacti and succulents. You may need to keep the shade cloth on the plant for the duration of the summer to prevent sunburn.

Shrubs should be planted in fall or spring.

Herbaceous perennials and groundcovers should be planted in fall or spring. However, many warm-season vines can be planted during the summer months. Water immediately after planting and monitor the moisture for the next few days to keep the root ball from drying out. Water newly planted native and desert-adapted vines twice to three times weekly to a depth of at least a foot. Gradually extend the time between watering and monitor plants regularly for signs of water stress.

VINES TO BE PLANTED INCLUDE:
• Yellow Orchid-vine (Callaeum macropterum)
• Queen’s Wreath (Antigonon leptopus)

Planting of cacti seed can continue. Seed can be soaked overnight in water to help begin the germination process.  Place seed in a well-draining soil mix (½ quality potting soil and ½ perlite or pumice) and lightly cover. Keep soil moist until germination occurs.
VEGETABLE SEEDS TO SOW INCLUDE:
• Armenian cucumbers
• pinto beans
• black-eyed peas
• tepary beans
• snap beans
• muskmelons
• cantaloupes

Pepper and tomato seed may be planted indoors and transplanted in August or September for a fall harvest.

Wait until fall or spring to plant most herbs.
