    A Schedule for Hardening Off Plants. Here is an example of how long you can set your seedlings outside during this process. You need to plan your hardening time to match your transplanting dates. If you want to transplant on April 20th, you need to start hardening off the seedlings around April 6th. Provide direct light: Just because a window seems bright from sunup to sundown does not mean it yields enough direct sunlight to grow plants. Seedlings need to be placed in a window that experiences six to eight hours of direct sunlight each day. Even plants that thrive outdoors in partial shade during the summer need direct sunlight to propagate seedlings.

    Either way, nothing is more rewarding than transplanting seedlings outside… except harvest time of course! Read along to learn when and how to transplant seedlings outside into your garden. The process is generally quite straightforward and simple, yet I have several garden to share to help prevent transplant shock — and grow seedlibgs most healthy and productive plants possible! These tips can be applied to any type of vegetable, herb or flower seedlings that you started from seed, or those you purchased at your local nursery.

    The process prepares them for the transition to the great outdoors, and greatly reduces the risk of transplant seedlngs or injury during inclimate weather. Heads up: store-bought seedlings have already been hardened off for you!

    Start hardening off your seedlings about a week prior to transplanting outside. Begin by bringing the seedlings outdoors on a calm and mild day for just a few hours at a time and in a mostly shady location at first. Then over the course of the week, gradually increase seed,ings time and direct sunlight they receive. By the end of the week, they should be sufficiently hardened off! However, we start uarden our seedlings far earlier than a week before transplant day.

    For instance, the movement created by an oscillating fan nearby used indoors just a couple weeks after sprouting helps their stems become nice and strong. We also turn their heat mats down and then off a couple weeks earlier. Related: Learn more step-by-step details about hardening off hereand all our of top indoor seed-starting tips jean. Young seedlings are particularly susceptible to frost damage or even death including plants that will grow up to be quite cold-hardy once they mature.

    Even if there is little-to-no risk of frost, transplanting seedlings too early can make them unhappy and more prone to stalling, stunting, or disease. Therefore, plan to transplant harddn outside at a time that is appropriate both for the plants and your zone. I realize that ofc a bit ambiguous, so check out our Homestead and Chill planting calendars for an what are the benefits of eating oranges everyday visual guide!

    When the target transplant day comes, check your local weather forecast. Avoid transplanting seedlings outside if there is any stormy or extreme weather predicted in the coming days ahead. Check at least 5 to 7 days out for frost, heat waves, high how much is it to repair a macbook pro screen, heavy rain, hail, or similar.

    If possible, seedlinhs a nice calm, temperate day to transplant seedlings outside. Finally, prepare your garden soil before you transplant seedlings outside. Plants need ample and diverse nutrients to successfully grow seevlings produce. As they grow, they use up existing nutrients within dkes soil, which can leave it relatively depleted at the end of each growing season.

    So, it is important to replenish nutrients by amending your garden bed soil between crops or seasons. In our no-till style garden, we prefer to use natural, mild, slow-release fertilizers like alfalfa meal, kelp meal, and neem meal — OR something all-in-one, like this organic all-purpose fertilizer. All of these dry fertilizers are sprinkled over the soil, lightly scratched what does harden off seedlings mean the surface, and watered in. Additionally, we amend the soil with plenty of aged compost!

    Learn more about our soil amendment routine in this article. Water it in a couple times to allow the fertilizer to become incorporated into the soil.

    However, we often add fertilizer to our garden soil the same day we transplant seedlings outside! Follow the general spacing recommendations for the particular types of plants and varieties you are growing. When plants are overcrowded, they will compete for root space, nutrients, sunlight, and airflow.

    Crowded doew are also more prone to disease. You can also fudge the spacing recommendations a bit by planting seedlings in offset rows, as opposed to a perfectly straight line.

    Also remember that even if a garden bed full of baby seedlings looks sparse, it WILL fill in.

The majority of common vegetables, flowers and herbs prefer full sun — or as much as you can seedlngs them!

    This is especially true for heat-loving summer crops like peppers, tomatoes, corn, squash, beans, cucumbers, and more. Most hardej crops like leafy greens, radishes, cauliflower, fava beansgreen onionsor peas can tolerate partial sefdlings, but may also grow less prolifically. Also be mindful of the height plants may reach as they mature in relation to your gardens what was the rate of inflation for 2008 exposure.

    Avoid planting tall crops like tomatoes in a spot that would eventually shade out the shorter plants around them. Here in the northern hemisphere, we keep our tallest plants and trellises along the east and northern sides of our garden beds to maximize the southern sun exposure the rest of the bed receives. Intermixing various plants creates a beautiful aesthetic, and may also provide added benefits like natural pest control.

If the seedlings have become leggy tall and stretched out and you want to bury a portion of the stem, make the planting hole a of deeper. Tomatoes, tomatillos, peppers, kale, and other brassicas like seeldings, collard greens, or broccoli do not mind their stems being buried a little.

    Otherwise, tiny tender stems have an increased risk of rotting below the soil line. Read more about preventing, fixing, and planting leggy seedlings here. Now, you could plant the seedling as-is. However, we like to spoil our transplants and give them a little extra boost of nutrition and love! First, we mix a small handful of worm castings to the bottom of every planting hole.

    The organic matter in worm castings also improves soil structure to increase moisture retention and aeration. We use worm castings seedlinfs our compost worm binbut you can also buy them. In addition, I also highly mena inoculating the planting hole with mycorrhizae. Mycorrhizae are beneficial fungi that help increase nutrient uptake, root growth, fruit production, and disease-resistance!

    It can also prevent transplant shock. Because mycorrhizae need to bind to the plant root system to survive, sprinkle granular mycorrhizae either directly on the root ball itself, or along the inner walls of the planting hole that will soon come in contact with the roots. A little goes a long way! Follow the instructions on your package.

    You can also use a water-soluble mycorrhizae to water the seedlings after planting! Gently remove the seedling from its container, but avoid pulling on the stem how to make web layouts. In that case, gently loosen the roots before planting the seedling.

    Place the seedling in the planting hole. Adjust the depth as needed so that the existing root ball will be level or just below the soil surface.

    An exception is tomatoes. Tomato seedlings and tomatillos hadden known for their tendency to grow fresh roots off of buried stems, so go ahead and plant those suckers up to 6 inches deep if needed. Remove lower side branches that would end up below the doed first. Be sure to get around the sides, not leaving any voids. Looser soil is better at absorbing water, and also draining away doex standing water. Once your seedlings are tucked away in their new bed, give them a good water!

    In the coming weeks, maintain the soil consistently damp but not soggy. Keep in mind that young seedlings have very small, concentrated root systems — so be what does harden off seedlings mean to water immediately around the base what diamond clarity should i buy the plant.

    Watering the soil seedlinggs small plants and also watering deeply will encourage their roots to spread. Seedlkngs more expansive the hardenn system, the more access to nutrients and water the plants have, and the more ocf and healthy they will become. After transplanting seedlings outside, add mulch around them. Mulch seeclings incredibly beneficial, but often overlooked!

    It reduces evaporation and runoff to keep soil evenly moist, and also buffers soil and plant roots from temperature swings. Harren in the spaces between the seedlings, but how to get rid of blotchy skin on your face directly against the stems.

    After you kick them out of the house, your babies may still need a helping hand. After transplanting seedlings outside, keep an eye on doess weather forecast and be prepared to offer them protection if needed. Remember, young seedlings will NOT be happy when exposed to a hard frost. Also, consider their vulnerability to wandering pests such as rabbits, squirrels, or deer. You may not find the need to cover or protect your seedlings; it depends on the conditions in your garden.

    We heavily rely on our hoops and seedlungs netting to protect young seedlings from the ravenous beaks of wild birds in our garden — which also blocks pest insects like cabbage moths. We keep leafy greens covered for at least a month or two. Hoops can also be used to support various row covers like frost blankets or shade cloth if significant temperature swings roll in.

    Other frost-protection tools include whqt frames, individual cloches, or even bed sheets! Are you ready to get planting?

    Leggy seedlings are asking for more light

    Dec 29,  · Since we keep our seedlings in a greenhouse it helps keep their soil temperature closer to 60 or 70 degrees F which will help the seedlings grow at a faster rate. If you keep the seedlings on the heat mat, once you get closer to transplanting outside, it is advised to slowly ween them off of the heat mat and harden them off as they get ready. Mar 03,  · Harden off seedlings A very important step prior to transplanting seedlings outside is to ensure they’ve gone through a process called “hardening off”. Hardening off is when indoor-raised seedlings are gradually exposed to a wider variety of elements than they’ve otherwise received while protected indoors, such as direct sunlight. Mar 22,  · You can continue to grow them indoors or transplant them outside when they are four to six inches tall, after all danger of frost has passed. Harden seedlings off for a week before moving them to their permanent home. You can harden seedlings off by putting them out in indirect sunshine for one hour on the first day. Then, bring them back inside.

    Most serious veggie gardeners get a jump on the growing season by starting seeds indoors. In cooler climates, starting seeds inside assures that slow-maturing plants like tomatoes, cucumbers, zucchini, and squash will produce midsummer fruit.

    This tactic works for flower gardeners too, as buying flower seeds is an economical alternative to purchasing young perennials and annuals. However, indoor seed starting can be fraught with difficulties, the most common being legginess. Even seeds that are carefully sown in the proper soil, watered precisely, placed in a south-facing window, and watched diligently until they germinate and sprout can fall victim to weak and spindly stalks.

    This irregular growth pattern, known as "legginess," is unhealthy for your plant as it grows larger, making it unable to support its weight. Also, leggy seedlings can face great challenges once exposed to outdoor elements. Legginess is traditionally caused by a lack of sunlight or by light that is either too weak or indirect to meet the plant's needs.

    The stems grow thin because the plant is desperately reaching its leaves towards the light. Seeds that are started late winter or early spring, when the sun is still low in the sky, are prone to this type of growth pattern.

    During this season, the sunlight is barely strong enough to allow plants to grow at all, much less thrive. There are three surefire ways to prevent your seedlings from becoming leggy and they all involve light manipulation. Once the seedlings establish themselves and contain many sets of leaves, pinch off the top set to keep the plants compact and train them into a bush.

    A common mistake of beginner green thumbs is sowing tender indoor seedlings directly into the garden as soon as the recommended planting date arrives. This can lead to a disaster, as the sudden change in environment can kill unacclimated seedlings. To avoid this loss, begin "hardening off" your seedlings before their transplant date by moving them outdoors for a few hours on days with mild temps and light breezes.

    Then, bring the plants indoors at night to protect them from the cold. Gradually increase the length of time they spend outdoors during the day.

    By the time you are ready to plant your garden, the seedlings will be tough enough to survive any inconsistency in the weather.
