Ready or not it’s time to start planning the fall vegetable garden. Fall gardens may face additional pressures of pests and heat, but the flavor that comes from these late season crops are often better. Fall planting requires attention to the number of days to harvest as well as the crops’ tolerance to frost. Crops may be direct seeded or transplanted into the garden. Growing transplants is a good choice when the temperature is too warm for starting seeds in the ground, if you have grow lights and space available for starting them indoors. 

When seeding crops directly into the garden, plant slightly deeper than recommended in the spring to take advantage of the cooler soil temperatures and moisture available. Water more frequently to prevent the seeds from drying out. Overhead watering often causes soil to crust, making it more difficult for young, tender plants to emerge. Prevent this by applying a light sprinkling of vermiculite or compost over the row after seeding or use a soaker hose or drip irrigation right next to the row to allow water to slowly seep into the ground. 

Mid-July:

Plant potatoes if you can find seed stock or have saved seed potatoes. Do not use freshly dug potatoes as they have a built-in dormancy that will prevent growth. Also, grocery store potatoes are often treated so they don’t sprout. 

Cabbage, broccoli, and cauliflower can be started from seed at this time. Choose a protected place where the soil can be kept moist and rabbits will not bother them. This will not be where they will grow the entire season but these crops will be transplanted about mid-August. 

Late July:

Seed beets, carrots and beans. 

Late July to Early August:

Seed spinach and long-season maturing lettuce. Leaf lettuce will be seeded later. 

Second Week of August:

Transplant cabbage, broccoli and cauliflower to their final location. 

Mid to Late August:

Seed radishes and leaf lettuce. No need to fertilize before planting. Side-dress two weeks after transplanting or four weeks after sowing seed by applying 2 tablespoons of a 16-0-0 or 1 tablespoon of a 27-3-3, 30-3-4 fertilizer, or something similar per plant. 

The Kansas Garden Guide is a great resource for additional information about fall gardening.
