Perhaps the last garden chore of the season is tucking in the strawberry planting for winter. Strawberry plants have already set their buds for next spring’s flowers and the crop can be lost unless you protect them from harsh winter conditions. A fully dormant strawberry plant’s flower buds can be damaged at temperatures below 15 deg. F.
\n
\nIn addition to flower bud damage, the alternate freezing and thawing of the soil that commonly occurs in winter and early spring can cause plant roots to break and the plants to be heaved right out of the ground.
\nMulching strawberry plants will insulate them from extreme low temperatures, minimize soil heaving and decrease excessive drying (desiccation) of the plant crowns. But be sure to wait until plants are dormant before you pile on the mulch. Applying mulch too early can cause the crown of the plant to rot. Plants should be mulched before the temperature drops below 20 deg. F, usually by late November or early December in most parts of Indiana.
\n
\nSeveral materials can be used for winter mulch, including clean (weed-free) straw, chopped cornstalks, hay, corncobs or bark chips. Tree leaves and grass clippings are not recommended, since they tend to mat down and smother the plants. About 2-3 inches of mulch, after settling, should provide adequate protection.
\n
\nPut a note on your garden calendar to uncover the plants in spring as new growth begins. Rake off most of the mulch as soon as the first new leaves develop. The new growth will probably look a little yellow at first but will green up with exposure to light. Rake the mulch between the rows to provide weed control and a source of emergency cover in case frost threatens. Mulching around the plants will also help keep the berries clean.<\/p>\n
