What Do We Mean By Fall Gardening?

Planting crops that can be overwintered for winter or spring harvest.

What Do We Mean By Fall Gardening?

Planting cover crops on unused beds to increase soil fertility and minimize winter weeds

What Do We Mean By Fall Gardening?

Extending the season by using a cold frame, greenhouse or low tunnel.

Preparing the SiteRemove waste from previous crop.If ground is dry, give it a thorough soaking.Work compost into top few inches of soil.Add recommended amount of Nitrogen (.20#/100

sq. ft. of garden.

Fall Days & Cooler TempsCool nights slow plant growth but you can

speed up growth using row cover or plastic.

Vegetables take longer to mature. Days grow shorter, less sunlight energy for plants. Add 14 days to maturity time for so called short day factor

These environmental conditions add sugar to cole crops.

Lettuce and spinach will not bolt.

Cover Crops

• Check out GIEI website for info on cover crops– GE006_CoverCrop2.pdf

• Different cover crops do different things– Break up clay soil (forage radish)– Deep root systems to capture nutrients (winter rye) – Add nitrogen to the soil (legumes)

• Plant a legume and cereal together to get additional benefit.

• Cover crops can be planted in any unused beds at anytime of year but no later than mid-October.

Winterizing the Garden• September

– Pull up and compost undiseased spent plants– Plant spinach and kale for spring harvest

• October– Pull up and compost undiseased spent plants.– Cover pepper and tomato plants to prolong production.– Remove and store stakes and cages.– Plant cover crop in empty areas. Till in organic matter.

• November– Cover empty beds with shredded leaves to stop winter

weed growth. – Mulch overwintering carrots, leeks, winter onions,

strawberries, radishes and parsnips with clean straw. • December – Get soil sample for spring planting

Compost and Leaves Covering Beds

Rake & Take Program

• Leaves are available through the Howard County “Rake and Take Program” or you can just pick them up from your neighbors.
