Salad greens generally prefer to grow in cooler weather conditions, thriving in temperatures around 60 degrees F. This makes them a great spring and early summer crop, but growing great greens can start to get tricky in the hottest months of the year and in areas that receive full, direct sun. Many salad greens tend to bolt quickly when the weather starts to warm up. During the hottest months of the year, it's important to choose types and varieties that will hold in the garden. This week we have Natalie Carver, from Love and Carrots, a DC-based edible landscaping company, to discuss warm weather salad greens with us.

In this episode, we discuss:
Why growing salad greens in warm weather can be challenging
Loads of tips and tricks for growing and harvesting salad greens in warm weather
Our favorite varieties of warm season greens
Heat is definitely a stressor that causes plants to bolt, but another factor is hours of daylight.
There are various strategies to successfully grow salad greens in warm weather and longer days, including:
Finding a shady microclimate in your garden
Using pelletized seeds for ideal spacing
Selecting varieties that are heat-tolerant
To prevent bitterness, harvest in the morning, ideally before the sun reaches the leaves.
The varieties we discussed on the episode include:
New Red Fire: a reliable summer lettuce, great texture, red leaves with green at the base
Adriana: a butterhead/boston variety with leaves that are lightly folded
Coastal Star Romaine and Jericho Romaine: romaines in general are slower to bolt in warm weather
Summer Lettuce Mix: a cut-and-come-again variety
Asian Greens, including Mizuna and Joi Choi
Green Wave: a broad leaf mustard green
Purslane: a cultivated, upright version of the common weed, with a crisp, almost cucumber-like flavor
