Plug plants are a fantastic and affordable way to quickly and easily add summer color to your yard.
Although seeds are less expensive to purchase, properly sowing and cultivating them requires the purchase of propagation equipment. Germination can also be hit or miss, and picking out tiny seedlings is a tedious task. Purchasing plug plants allows gardeners the luxury of delegating the more difficult initial stages to the professional grower, who will then take over once the young plants are somewhat more established and are grown until they are ready to be potted up or planted into their final positions, each in its own plug of compost.
The size of the plug plants when you purchase them will determine how much work needs to be done on them and how much you will pay. Smaller animals cost less, but they often require more care.
- The first of the season, mini plugs begin to fill garden centers and nurseries in late February. These require the most care and consideration as they grow in trays or pots. Before planting out ready to flower, they must be transplanted and nurtured on a windowsill, in a greenhouse, or in a conservatory.
- The next step is standard plugs, which need to be potted and grown on for about a month if you want filler plants for beds and containers.
- Garden-ready plug plants are often healthy, established plants in pots that can be planted right away in their ultimate location in the garden. However, these plants may also benefit from being grown on for a few weeks in a large pot to give them time to develop more robust roots.
As soon as possible after purchasing, plug plants should be transplanted into larger pots or trays.
Just moisten your plants with water. The best way to accomplish this is to submerge them in water and let their roots absorb it.
Make a hole in the center of a tiny pot or seed tray with good quality, freely draining multipurpose compost that is roughly the same size as the plug plant. Pinch the plug’s bottom gently and push upward while holding it by the leaves. Place the root ball in the hole, making sure the stem is level with the surrounding compost as it was previously, and lightly compact the compost to seal the plug.
Water the newly planted plants gently, letting any extra water drain away. Put them in a place that is well-ventilated, well-lit, and somewhat warm, such a greenhouse or windowsill. Feed them a balanced liquid feed at 23 weeks, and then do it again every 10 to 14 days.
You can harden off your plants so they are ready to be planted outdoors once they are strong and well-grown. This only entails leaving them outside in a protected area during the day and bringing them inside at night to acclimate them to lower outdoor temperatures for a week or two. Keep them inside until the winter weather passes if the temperature falls below 5 C.
Your plugs should be prepared for planting out into their final position once the plants have established strong roots in the compost and the risk of frost has gone. One to two hours before planting, as well as once they are in place, give them a good soak. After planting, make sure to water frequently, especially during dry, sunny days.
Must I take out the plant plug?
There is a widespread notion that “plugs” are problematic. Unfortunately, it has worsened due to plant problems and deaths brought on by indoor gardeners mistreating the plants, which has prompted them to investigate the root of the problem. The fault lies with these indoor gardeners because they don’t comprehend the plug’s function or proper use.
When the plant begins to suffer, the owner probes the soil to determine why, notices the plug and the absence of roots, and comes to the conclusion that the plug is the problem. In actuality, the healthy plant’s root system has rotted away, and what is left of it is barely surviving outside of the plug. The plants frequently start out appearing depressed from overwatering, then the color or general appearance may fade from lack of nutrients, then the plants start to look thirsty from the lack of surviving roots that can adequately hydrate the plant. At this point, the plant may occasionally receive additional water, aggravating the problem. Last but not least, the indoor gardener digs about in the soil and discovers the plug but no roots, wrongly supposing that the plug has’suffocated’ the roots and is the problem.
Even though the plant has roots that extend beyond the plug and into the soil, some indoor gardeners will notice the plug early on and name it nasty or a “death plug,” which is inaccurate and extremely evocative. Then they assert that once the plug was taken out, the plant flourished. Once more, what has actually happened is that a plant in a pine bark potting mix is no longer being overwatered as it was before, thanks to the removal of the plug. The plant is once more content and able to thrive because it is now receiving the appropriate water for the medium it is in, one that dried out very quickly. It is clear that the plug never prevented this from happening; rather, the plant was just having trouble growing in a pot with two different soil types and inadequate irrigation. Of course, once a plant is owned by an indoor gardener, they are free to do as they like, but pulling out the plug can frequently harm the plant’s root system. After this happens, the plant must re-establish it in order to continue growing or, in some situations, the plant will perish.
When you receive plug plants, what should you do with them?
Though this will vary across plants and the plug size you purchased, they often arrive with five to eight pairs of “true” leaves. They come in particularly handy if you haven’t sown yet or don’t have the resources to raise a large number of plants the conventional method. Additionally, they demand less heat and moisture than seeds, which is good news if you want to grow plants like petunias, nicotianas, and French marigolds, which require a decent amount of warmth to sprout.
The majority of plugs are purchased online. Don’t place them directly in the garden once they arrive; slugs, snails, and other pests will probably consume them. Check their health and integrity after removing the wrapping.
Alan Titchmarsh shows how to make sure your plug plants grow and thrive in the No Fuss video instruction above. He gives instructions on how to remove plug plants from the delivery trays they come in as well as how to pick the appropriate size pots and compost for your plug plants to grow in.
When may I transplant plug plants outside?
Plug plants are significantly easier to grow than fully grown plants and far less expensive to purchase than completely mature plants. The benefits of learning how to grow on plug plants are worth learning.
Typically purchased online from specialized nurseries, plugs are annual, bedding, or vegetable plants. Unpack them as soon as possible after arrival, then stand them in water until the compost is moist. Allow them to acclimate in a warm, well-lit environment for up to 24 hours before planting.
Size affects how much attention plugs need before being planted:
- Early in March, little plugs begin to appear; they require the most attention and time to develop in trays or pots.
- The next type of plug you can use as filler plants for beds and containers is a standard plug, which needs to be potted and grown on for about a month.
- If the weather is warm enough, garden-ready plugs can be planted out right once, but they can also be nurtured for a few weeks in a big pot to develop stronger roots.
What causes my plug plants to die?
The demise of plug plants can result from a variety of circumstances. Even though a person who has already passed away may not be able to be revived, it is still crucial to figure out what happened so that it does not happen again.
Deep planting may lead to plug plants dying
Your plug plants naturally require warmth, moisture, and oxygen for healthy growth. They are typically cultivated near to the soil’s surface because of this. Your plant can rot if you plant it deeply.
Poor watering routine may lead to plug plants dying
If you don’t give your plant the necessary amount of water, the roots will begin to dry out, which will cause your plug plant to die. Overwatering, however, kills them far more frequently. If you overwater your plant, water will replace the oxygen and it will get weaker. Your plug plant’s roots will eventually die as a result of stunted development, fading leaves, and other effects of this.
Too much fertiliser may lead to plug plants dying
This may modify the fundamental elements of the soil, resulting in a high salt concentration and, as a result, altering the soil’s helpful microbes for your plant. Your plant may grow quickly as a result of over fertilization, yet the root system may still be immature. This will result in the plant receiving insufficient amounts of nutrients and water.
Too much, or too little light may lead to plug plants dying
Your plug plant’s exposure to sunlight can have an impact on the photosynthesis, respiration, and several other growth processes that it will go through. The leaves of your plug plant will get bleached and blotchy from prolonged exposure. On the other hand, insufficient sunlight will impede photosynthesis, causing the plant to climb upward and stretch its stems and leaves in an effort to catch more sunlight. This process is known as etiolation.
Incorrect Humidity may lead to plug plants dying
When developing plug plants, it is advised to begin with high humidity. As the plant develops, you might decrease the humidity. As a result of high humidity, mold and bacteria might form. Your plant can get hurt or perhaps die as a result of this. On the other hand, low humidity will result in severely parched plug plants. The leaves will turn brown and the stems will droop. Your plug plants will eventually die off and sustain irreparable damage.
Pests may lead to plug plants dying
This is a problem that plant owners frequently run into. Some of these pests can be too elusive to identify. Fortunately, the majority of them leave behind “footprints” like cotton heaps of fine webs. Pests may devour your plug plant’s leaves, reducing photosynthesis and inflicting damage that makes your plant more susceptible to illnesses and eventual death.
Which compost is ideal for potting on plug plants?
Our Opinion: Both John Innes No. 1 potting compost with a peat or loam basis contain enough fertilizer to aid in establishing the plugs without harming the roots.
Do petunias like shade or the sun?
Petunias require at least 5 to 6 hours of adequate sunlight, and they thrive in locations that receive full sun all day.
While soil doesn’t have to be incredibly rich to produce good petunias, it does need to drain well.
It’s always beneficial to condition garden soil with organic matter, such peat moss, compost, or manure.
Use a rototiller or garden fork to incorporate it into the soil 8 to 10 inches deep.
increases the capacity of light, sandy soil to hold moisture and nutrients while also aiding in the opening up of heavy clay soil, which enhances drainage.
