When to plant seeds indoors zone 6-9

Can I plant seed indoors and transplant into the garden zone 10 and up? It is time to harvest. Heaviest radishes can be planted outside as soon as soil temperature has reached 50 degrees F.

My one-year-old red seedlings are about 2 1/2 inches high. I noticed an online article saying radishes should not be planted indoors until after the last frost. Is that true, and, if so, what is the proper time?

ANSWER Hi Sara,

Before last frost dates are shown, consider planting until frost is expected. I’ve been doing it for decades and it has worked well for me and others I know. I’ve found the best way to do it is to start seed indoors, because the day the seed is planted, the air and soil temperatures are warmer than the night before and you want those temperatures to be high enough for seed germination and seedlings to emerge but not high enough to cause damage.

Most gardeners think of the last frost as the date to plant seeds, but for the purpose of successful germination of a wide range of plants (even strawberries!) start seeds when air and soil temperatures are warm.

Also, realize that just because you planted the seed out of the house doesn’t mean it will be mature when it emerges. Don’t plant seeds indoors until the air and soil temperatures in the rooms where you’re planting are 70 degrees F. If it’s still a bit cold, wrap the seed-starting flats in foil and keep them on top of the refrigerator to increase the air and soil temperatures and delay the germination of your seedlings.

Another benefit is that by the time the last frost date arrives you should have some seedlings in the ground already.The last frost also allows you to plant perennials that are all but dead in the ground the day of the last frost and still emerge.

Try this:

When it’s frosty outside the next day check your seedling trays. You’ll see some seeds germinating. To hasten the emergence of those seeds, put the trays in a warm location.

If you don’t have a window on a north-facing wall, build a shade-cloth tarp. Cut a 15-x-15-inch square from the shade cloth and lay it over the trays. Don’t cover the whole tray or it may cause your seedlings to bolt to seed.

Over the last week of April, after the last frost, move the plant-starting trays into a warmer location.

Mature plants benefit from some days of cool temperatures to help initiate their growth cycle. However, even the most heat-tolerant plants will die if temperatures go above 95 degrees F for more than a few minutes. A gradual warming of the soil is best for optimum germination of many plants.

If you don’t have a heated greenhouse, a basement heated to 70 degrees F is a good bet, or buy a system of plastic pipes with electric heat tape.

NEW FLOWER INNOVATIONS

New seed-sowing machines do it all

Just last month we featured a new in-ground automatic seed drill that allows you to sow your entire garden from one single operation. You could skip that step with one of the new automatic seed sowing machines that are available. The Garden Super and Craftsman have a range of machines to suit your needs and abilities.

Craftsman has introduced a new line of accessories for the Craftsman Super and Craftsman Series seed planters. These accessories provide better depth control of the soil, thus making seeding uniform. The Ultra-Grow allows you to use the sowing/shaking mechanism to more than double the seeding rate to 35,000 per hour.The Super Collides allows the farmer to safely increase the seeding rate to 80,000 per hour and the Ultra-Seed system provides an even faster rate of 130,000 per hour. All of the accessories for the Craftsman Seed Sowers are now available in the optional sizes of the Super, Standard and Elite.

We have tried out a few different automatic seed planters and find the Garden Super and the Craftsman to be the most popular choices. The Craftsman Series has several accessories, which include a variety of seed drills, planters and fertigation systems. The seed drills for the Craftsman Series are available in seed options that include from 5,000 to 12,000 per hour. These seed drills are available in single and double seed drills.

The Garden Super Series includes drills from 3,500 to 20,000 per hour. The drills are available in double, triple, and double-dual seeder options. They are available in both upright and rear-tilted options.

Another great benefit to the Craftsman seed planters is their ability to customize their tools as they grow. The planters come in an array of colors to match your farm or garden. The seed planter handles offer comfortable grips and wide seats, which allows you to ride comfortably all day. The seed planter also comes with a 60-hour continuous battery.

We find the Craftsman Series seed planters to be comfortable, quiet, and very convenient. They are quiet because they have a fine metal impeller on the front, which reduces soil agitation. They are quiet because they are fully enclosed and have limited visibility. They are quiet because they are battery operated. They have high-quality cast aluminum seeding wheels that guarantee long service and have smooth operation. They are quiet because they have a simple design that allows for greater accuracy when selecting depth and spacing of seeds. They are quiet because they use a 12 volt, 60-hour battery with a heavy duty cover.They are quiet because they have been proven in commercial and consumer gardens in all different types of soils.

    You have hit the mark. It seems to me it is very excellent thought. Completely with you I will agree.

    It was and with me. Let's discuss this question. Here or in PM.
