Many of us have grown up with the rule of planting the vegetable garden on Victoria Day (May 24th) long weekend. With the changing weather, hardier plants and stretching the limits, we have realized that many plants can go into the ground well before that date, while others do need the soil to be warmer.
Cool Weather Crops
Cold weather crops like lettuce, spinach, pea, beet and carrot seeds can be planted well before that mystical date. They actually like a cooler temperature to germinate. If you plant them the first week of May, you should have sprouts coming up by the time you plant other seeds.
Warm Weather Crops
Ground temperatures need to be warm for beans and cucurbits such as squash, pumpkin, cucumber and zucchini. Mid May to early June is probably best for putting actual plants in the ground, if you are in an area that does not get frost. Check your weather network for overnight lows. If the temperatures drop and the night sky is clear, chances of frost are better than on a cloudy night. If the air is still, colder air will settle close to the ground and damage plants. If your property is on a slope or higher ground, the cold air will settle around you in the valleys and you may not be touched by a light frost. Being closer to water often draws the cooler air away. If you have planted tomatoes and peppers and there is a frost warning, go out and cover your tender plants with sheets.
Basil and cilantro do not like cool nights, so leave these tender herbs in pots to bring in overnight or do not plant until June.
Annuals
Some annuals such as pansies, dusty miller and english daisies are cold tolerant while others like potato vine and impatiens do not like temperature changes. Do not plant the latter 2 choices into the ground until all danger of frost has passed and the soil temperature has warmed. If the nights temperatures are dropping, bring your pots into your garage or cover with an old sheet to protect.
Perennials
Perennials have survived the winter frozen in the ground so a bit of frost will not hurt them. If you are buying perennials that have been grown and forced in a hot greenhouse, they will need to be pampered by slowly introducing them to seasonal temperatures. This is called hardening off. To harden off any plants that have been living in a warm greenhouse, put them outside in a shady area, protected from the wind for a few hours over several days. Bring them back into the warmth of your home or heated garage for the night. Increase the number of hours they are outside each day, until they are used to the outside temperatures.
According to the Farmers Almanac, the last frost date for Peterborough is May 14th, however the full moon is on the 28th. If the night of the full moon is clear and cool, we could see frost. Beware!







Turn Your Compost: It’s time to turn your compost pile and check for any that is black and crumbly and thus ready to use. Making your own compost is free and a great way to amend your soil! Add compost to improve soil by scratching in finished compost into the top one inch of soil.
In the summer of 2017 the City of Kawartha Lakes was officially recognized as a Bee City by Bee City Canada. I live in Lindsay and heard this first through our local newsletter last summer. Since then I attended our local horticultural meeting in January and heard Susan Blayney, who had spearheaded the project, give an interesting and enthusiastic talk on what exactly this means to the City of Kawartha Lakes and how a city can officially become a Bee City.
y the success of Bee City USA. Bee City USA is a non-profit organization, which was started in 2012 to help motivate communities to sustain pollinators. There are currently 62 cities and 33 campuses or educational institutes recognized through Bee City U.S.A.
The City of Kawartha Lakes has a number of initiatives that they are working towards, the largest being the Fenelon Falls Pollinator project. Last year, a 1.5 acre decommissioned parcel of land on the Fenelon Falls landfill site was reseeded with a pollinator friendly seed mix. This project is an ongoing pilot that is being monitored by students from Fleming College along with the Ministry of the Environment. Other initiatives that are being planned include pollinator gardens, a 100 garden challenge, education in schools and seed bombing along trails, roads and parks.
