There are many plants that can be propagated during winter. We often take cuttings during winter as it's a quiet time in the nursery. Most people may assume that it's simply too cold to take cuttings during the winter months, however there are quite a lot of plant species where winter propagation is the perfect time.
It's the perfect time for taking winter cuttings, meaning more plants for free - and who doesn't like that? Taking cuttings can be really fun and a great way to keep your green fingers active over the winter months.
Cuttings from many annual plants will keep over winter, sprout roots, and be ready for planting in spring. You may place them in pots or cups without drainage filled with moist perlite or vermiculite. Locate them at first in bright light, away from the sun. Move later to an area where they receive morning sun.
When winter propagating, cuttings will need protection from the elements and some moisture. Protection may be in the form of a poly tunnel, kitchen windowsill, enclosed porch, or cold frame. Whatever you are using should be well lit, frost free, ventilated, and offer wind protection.
Hardwood cutting are taken in the dormant season (mid-autumn until late winter) after leaf fall, avoiding periods of severe frost. The ideal time is just after leaf fall or just before bud-burst in spring. Although this type of cutting may be slow to develop roots and shoots, it is usually successful.
Taking cuttings is a great way to propagate new plants. You can take cuttings at any time of year in a variety of ways, but the easiest (and most successful) method is by taking cuttings of plants' stems in summer.
Herbaceous cuttings can be taken throughout the growing season (spring to late fall), while softwood cuttings should be taken in spring or early summer. Cuttings can be taken as long as the parent plant is healthy and in active growth.
A common rooting temperature target is 73 to 77° F. To accomplish this, propagators who grow on the floor use in-floor heating, which is usually installed when the greenhouse is built. This is usually an energy-efficient method to increase the root-zone temperature and second- arily, the air temperature.
Numerous plant species are propagated by stem cuttings. Some can be taken at any time of the year, but stem cuttings of many woody plants must be taken in the fall or in the dormant season. Tip cuttings: Detach a 2 to 6-inch piece of stem, including the terminal bud. Make the cut just below a node.
That is, roots remain mostly inactive but can and do function and grow during winter months whenever soil temperatures are favorable, even if the air aboveground is brutally cold.
Warm growing medium temperatures accelerate cell division which leads to faster callusing, root initial development and subsequent root growth. It also speeds up the dry-down rate of the growing medium, which also helps encourage better rooting. The best way to warm the growing medium is through bottom heat.
It will slow transpiration while the necessary components are used at the root sites to build a new root structure. Keep the atmosphere around the cutting warm (not hot), keep the humidity relatively high (>90%), and keep the root zone temperature warm (at about 25°C).
When to take cuttings. The best time to take softwood cuttings is from mid-spring to early summer. Hardwood cuttings are taken later in the year, from mid-autumn to mid-winter.
Cuttings will root more quickly and reliably in warm rooting mix. Keep your cuttings between 65°F and 75°F, avoiding excessive heat. If your area is too cold, consider a heating mat or cable especially designed for this purpose.
September/October is the ideal time to take cuttings from your favourite strains of tender perennials to increase your stock for next spring or to make sure they live on if the parent plants do not survive the winter.
Plant patents
Translation: you cannot divide that overgrown perennial, root cuttings, or layer branches if the plant is protected by a plant patent. Basically, the only legal way to reproduce a plant with this type of patent is by seed.
Technically, you can transfer your cuttings to soil at any time. In fact, you can actually propagate directly into soil, however, it's much harder to do within your home. When you propagate in soil, you have to keep a good balance of soil moisture, air flow, and humidity.
Some plants like papaya, marigold, chilli, capsicum, tomato, etc., cannot be propagated by asexual method. It is the only means of creating genetic diversity of plants. New varieties and cultivars of ornamental and vegetable crops can be developed only by this method.
Several cuttings may be placed together in one container. Be sure to add fresh water as needed until the cuttings are fully rooted. Rooting will generally occur in 3-4 weeks but some plants will take longer. When the roots are 1-2 inches long or longer the cutting is ready to be potted up.
Propagation for many plants is best done in potting soil, but some plants can be propagated in water. This is because they have evolved in an environment that allows it. Most Aroid plants can be propagated in water, including pothos plants, philodendrons, monsteras, and ZZ plants.
Most cuttings taken in spring will be flowering in their first summer. Those taken in late summer will be overwintering under glass and be ready to harden off during May. One of the keys to overwintering rooted cuttings under glass is to keep them on the dry side in bright frost-free conditions of around 7°C (45°F).
Answer: Autumn is a good time to take cuttings of outdoor potted, tender, tropical plants such as coleus and Pelargoniums (tender, tropical geraniums). Using a clean, sharp knife, cut 3- to 5-inch lengths from your “mother” coleus and geranium plants.
You can propagate houseplants at any time of year. This being said, the best time to do it is during their growing season – which is typically spring-summer. They will grow more slowly during the dormant months of autumn-winter.
