When Should Fall Fertilizer Be Applied In Ontario

Drought, disease, insects and weeds can leave your lawn looking thin and patchy (Figure 1).Damaged areas in turf will recover more quickly with two applications of fertilizer in the fall.The recommended species for overseeding are perennial ryegrass (general recommendation), fine fescue (for shade or low maintenance) and tall fescue (for drought tolerance).Control thatch in the fall.The ideal time for thatch control is the same as for overseeding and the first application of fall fertilizer.Core aeration cuts cylindrical plugs out of the lawn (Figure 2), breaking up the thatch and bringing up soil, which contains microorganisms, that help break down the thatch.Leave the lawn cut at the right height.To ensure good winter survival and early-spring green-up, make this fertilizer application when the turf has stopped growing but is still green, usually in mid- to late October.Fertilizer applied too early will promote succulent growth in the fall that will make the lawn more susceptible to winter injury.If you make a late-fall fertilizer application, spring fertilization can be delayed until late May to early June.The application rate for this time of the year is the same as for the early fall application (0.5 kg of nitrogen per 100m2).Nitrogen enhances fall colour and hence increases chlorophyll content.Since turf is not growing at the time of the fertilizer application, the sugars that are produced are not used for growth but are stored to enhance winter survival and spring recovery.With the addition of two properly timed fertilizer applications, your lawn will survive the winter better, green up earlier in the spring and have deep roots that will help it withstand next year's summer drought (Figure 3). .
