When to Plant Tomatoes

Whether you are spending good money on nursery stock or putting in the time and energy it takes to grow them from seed, you certainly don’t want to risk ruining your crop by planting too early or too late.Even if early transplants survive a few unexpected frosty nights, their growth may be stunted and struggling plants will be more susceptible to pests and disease.Since we all live in unique microclimates, it is always a good idea to keep a yearly garden journal with your own data on frost dates.You can spread a layer of thick mulch or black plastic out in the garden to help the soil warm faster in the spring.The only exception to this is for gardeners in very hot climates, where some shade – particularly in the afternoon – can be helpful to protect plants on scorching days.Some varieties take a long time to mature, though, and it is equally important to make sure there are enough warm days for plants to produce fruit before they are harmed by fall frosts.Looking at the number of “days to maturity” on the back of your seed packets will help you to determine the ideal planting window for your growing zone.Count backwards from this date, using the number of days to maturity listed on the seed packet or plant tag.If you live in a cold climate or get a late start on your garden, choose a variety with a shorter number of days to maturity.Many gardeners, however, choose to start even earlier, up to 12 weeks before the expected transplant date, to give their seedlings extra time to grow before planting them out.Set your containers in a warm location or on a heat mat, covered with a humidity dome if you have one to speed germination.Once the seeds have germinated, remove the lid and place your pots in a sunny window or under grow lights for 10 to 14 hours a day.Using artificial grow lights is especially helpful if you choose to start seeds on the early side when days are still short.Set the pots in a tray and add half an inch of water to the bottom every few days when the soil feels dry.Set the pots in a sheltered location outside for an hour or so, increasing the length of time each day over the course of a week or two until your plants have adjusted to the outdoor conditions.When at last it is time to plant tomatoes in the garden, find a spot with well-draining soil that receives full sun, or in hot climates, just a little bit of afternoon shade.Since tomatoes really need a few months of summer heat and sunshine for good yields, if you live in a warm climate with a long growing season, it doesn’t hurt to wait a few extra weeks after the last frost before planting them out.While it is still important to wait until after the last frost, warmer soil will certainly help newly planted tomato seedlings to adapt and grow faster. .
