When to Water advice is now on vacation until the spring 2022 planting season. However, follow the advice for winter preparations to the extent you can. NOTICE—-Garden hoses will freeze overnight when temperatures dip below freezing and will most likely not thaw during the day, even if temperatures are above freezing. Time to bring your hoses in.
Rainfall* over the past 7 days. Will resume in 2022.
Established lawns: Do not need watering and won’t benefit from supplemental watering for the remainder of the season.
Recently sodded lawns (within the last 4 weeks): Follow your watering schedule but avoid over-watering. If you feel squishy ground, suspend watering until that dries out.
Established perennial beds: Do not need watering. Just remember that you are preparing the plants for going into winter dormancy, and root moisture is important (after this season’s drought), so watering during sunny, dry spells in November is beneficial.
Recently installed perennial beds (within last 12 weeks): Root moisture going into winter is important now, so water if temperatures allow or bring your hoses in.
Established trees & shrubs: It is beneficial to water once per week. Keep in mind that with evergreens in particular (including boxwoods) you are trying to build up a moisture surplus heading into the winter season.
Recently installed trees & shrubs (within last 12 weeks): At a minimum, before you bring your hoses in, ensure a very deep soaking of the planted rootball. You need adequate root moisture heading into winter.
Established rain gardens: Do not need watering, and won’t need supplemental watering for the remainder of the season.
Recently installed rain gardens (within the last 8 weeks): Do not need watering, and won’t need supplemental watering for the remainder of the season.
