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.
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.
“Grafting, budding, and plant propagation can be done on many types of plants during the winter, not just hardwoods.” High humidity and moisture are important during the post-cut and post-grafting periods.
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.
Taking winter cuttings from your plants
Most deciduous shrubs are ideal for taking winter cuttings, such as dogwood, flowering currants, roses, honeysuckle, gooseberries and figs. You can also take cuttings from trees such as willow and poplar. You can take cuttings from a few evergreens, including holly and skimmia.
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.
Many of the coleus, geraniums, and some of the begonias that we all love in our pots will also overwinter well as cuttings. It's very difficult to bring the entire pot in, but you can take small cuttings, root them over the winter months, and then next spring plant them out in your containers.
Hardwood cuttings provide an easy and reliable method of propagating a range of deciduous climbers, trees and shrubs, and as bonus, they are taken from mid-autumn until late winter when more time is usually available to the gardener.
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.
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.
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.
The Art of Water Propagation:
However, we like to keep them in water on their germination plate forever, so we can enjoy the root growth as well as the foliage :-). As long as you give them proper nutrients in the water, they can thrive indefinitely without soil.
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.
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.
All plants require light for photosynthesis, the process within a plant that converts light, oxygen and water into carbohydrates (energy). Plants require this energy in order to grow, bloom and produce seed. Without adequate light, carbohydrates cannot be manufactured, the energy reserves are depleted and plants die.
September is a good time to take cuttings of many plants. Some plants, such as half-hardy perennials or tender shrubs, may not make it through the winter, so by taking cuttings you can ensure that you can enjoy them the following year.
Storage of cuttings
It is best to harvest cuttings in early spring and plant immediately but if this is not possible, cuttings can be stored safely for about 4 months. Store cuttings in a cool, dark, and moist place. Do NOT store in a wet area as this will promote root growth and weaken the cutting.
Late summer and early autumn is the perfect time to propagate your favourite plants by rooting cuttings! You may want to do this to have more of garden plants but often it is the frost tender varieties that are best over wintered as little plants. After all there is a limit to the space we all have on a windowsill!
Fall is the perfect time to take hardwood cuttings. Keep in mind that the source plant should still be actively growing when you take your cutting. Sure, the growth does slow down with the onset of lower temperatures, but most plants will still be in active growth until frost hits.
Take the cuttings any time between mid autumn and late winter. Different parts of the UK have very different weather conditions, take the cuttings when the leaves on the rose bush are starting to fall or have fallen completely in your area.
Certain herbs don't mind the cold: Thyme, rosemary, parsley, chives, and cilantro actually prefer cool temperatures. Some herbs are perennial, so you'll plant once and enjoy for years. Plant transplants now so you'll have fresh herbs for all the upcoming holiday feasts.
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.
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.
Using sickly plants or flowering shoots
Cuttings are very delicate and vulnerable so pests, disease, the wrong growing conditions, too much water or too little water can all cause them to fail.
