What to Plant in July: The Ultimate US Guide for Farms, Houses, and Apartments
Jul
As we head deeper into summer, a common myth circulating among new gardeners is that planting season ends when the intense July heat arrives. But experienced US growers know that mid-summer is actually prime time for your garden’s second act!
Whether you are managing acres on a rural farm, tending raised beds in a suburban backyard, or growing in containers on a sunny apartment balcony, July is the perfect time for succession planting. By sowing a second round of seeds right now, you can replace your spent spring crops and guarantee a continuous, heavy harvest well into the crisp days of autumn.
Gardening Know How
Here is your complete guide to the best vegetable and flower seeds to plant in July to keep your space productive and beautiful.
1. The “Second Wave” Heat Lovers (Late Summer Harvest)
There is still plenty of time to grow fast-maturing, heat-loving crops. The soil is already incredibly warm, which means these seeds will germinate rapidly.
- Bush Beans: Bush beans are honestly one of the easiest vegetables to sow in midsummer. They love warm soil, germinate quickly, and many varieties will begin producing tender pods in as little as 50 to 60 days. They thrive in garden rows or medium-sized apartment containers.Gardening Know How
- Summer Squash & Zucchini: Given enough sun, water, and space, these famously prolific plants often produce more than enough for even the most enthusiastic gardeners. If you have limited space on a patio, look for compact bush varieties rather than trailing vines.Gardening Know How
- Cucumbers: Cucumbers adore summer heat. When planted in July, they often grow rapidly thanks to warm soil temperatures and long daylight hours. Providing a trellis improves airflow and can help reduce disease issues,making them perfect for vertical apartment gardening.Gardening Know How
2. The “Fall Garden” Head Start (Autumn Harvest)
To enjoy a lush fall harvest, you have to start planting while it is still hot. These crops will mature just as the weather cools down.
- Broccoli: For a delicious fall harvest, start broccoli now to produce a crop well into November. These crops tolerate light frosts and actually taste sweeter when they mature in cooler temperatures.Urban Farmer+ 1
- Carrots: Starting carrots by mid-July yields a fall crop that will keep in the garden until used. They need deep soil, so if you are in an apartment, ensure you have a container that is at least 12 inches deep.Urban Farmer
- Kale: Planting kale mid-July through mid-August will yield an excellent harvest in the fall and winter.Urban Farmer
3. Keep the Pollinators Happy (Late Summer Blooms)
One of the biggest gardening trends right now is the urgent need for pollinator-friendly planting. Sowing fast-growing flowers in July keeps your vegetable yields high by attracting bees and butterflies.

3 Pro-Tips for Mid-Summer Seed Starting
Starting seeds in the heat of July requires slightly different tactics than planting in the cool, wet days of April.
- Water Deeply and Consistently: Summer sun bakes the top inch of soil rapidly. Consistent watering is essential, especially during hot spells, as drought stress can lead to bitter fruits in crops like cucumbers.Gardening Know How
- Provide Afternoon Shade: If you are growing in containers on a hot balcony, protect your fragile new seedlings from the harsh afternoon sun. Move the pots slightly or use a light shade cloth.
- Add a Layer of Mulch: Once your new seedlings are a few inches tall, add a thin layer of straw or dried grass clippings around the base. This locks the moisture into the soil and keeps the roots cool.
