What is Pruning?
Pruning is the careful and selective removal of plant parts, including branches, buds, leaves, blooms and roots. It should be considered a significant part of plant care. Trimming indoor plants can be done for various reasons. This can involve the removal of living, dying or dead plant parts. This will discourage pests and disease. A clean plant is a healthy plant.
Pruning is a good opportunity to inspect your plant for any care problems. Damaged, discoloured leaves or abnormal growth can signal the need to change your plant care routine. You can carefully prune affected areas and adjust your care to promote healthy growth in the future.
Purpose of Pruning
Understanding the purpose of pruning is vital. Most people often prune plants without knowing why they need to prune the plants. This leads to mistakes and may waste time on pruning that may not be necessary or pruning too late in the plant’s life.
Following are the primary reasons indoor plants are pruned:
- Maintaining Plant Health: Dead or dying sections of the plant can encourage pest infestation or disease. Removing these not only makes your houseplant look better, but reduces the risk of future problems down the line.
- Training a Plant: Pruning trains plant to promote or create a certain shape, height or width of a plant (lateral branching, bushy/compact form, etc.).
- Make a plant bushier: Removing the tips of a stem releases a chemical that stimulates the growth of more side-shoots and bushier growth. Use pruning clippers or your fingers (with gloves on) to nip out the tips.
- Keeping large plants in size: Plants can sometimes grow to become too large for a particular space, requiring their growth to be pruned out. Branches are pruned out accordingly to reduce the overall height and/or width. Removing or reducing long stems will help keep a plant’s size in check.
- Improving quality of Foliage: Foliage plants are grown almost exclusively for their foliage. Only a handful are grown for their blooms as well their foliage. A variety of plants bloom but these blooms need to be removed to encourage strong foliage development that is otherwise sacrificed somewhat to bloom development and seed production.
When is a good time to prune your Houseplants?
Houseplants should typically be pruned at the beginning of the growing season, which is late winter or early spring for most of the varieties. However, woody indoor plants are an exception to this seasonal rule, as it requires year-round pruning to remove dead leaves and branches.
A good rule of thumb for flowering species is to prune them just after they have finished blooming. If you prune right before they bloom, you will be removing unopened buds that would otherwise turn into the flow.
What should be Pruned?
- Dead, broken or cracked stems
- Diseased or discolouredstems
- Stems that are rubbing against one another
- Overly long stems that create a lopsided shape
- Tips of stems to encourage bushy growth
- Leading stem at the top of the plant, to prevent it from growing too tall
- Old flowering stems to encourage re-flowering
- Stems of plain-coloured leaves on variegated plants
- Brown or discoloured leaves
Tips after Pruning your Houseplants
If your plant is healthy, it should recover from pruning and begin growing again within a few weeks. If your plant gets a little droopy for a few days, do not worry. It might be experiencing shock, but it will bounce back. Pruning produces short-term stress for the plant, so it is important to avoid causing additional stress. Following are the tips:
- Avoid excessively bright conditions.Plants normally kept in direct sunlight are best moved to bright, indirect light for a few weeks to reduce potential stress from excess sun exposure.
- If your plant is normally kept in a darker area, try moving it to somewhere a little brighter. This will speed up photosynthesis and boost the development of new growth.
- Avoid the desire to repot at the same time as pruning your houseplants. Repotting may lead to root damage, which causes stress to your plants on top of that caused by pruning. Leave a gap of at least 4 weeks between pruning and repotting for most houseplants.
- Avoid fertilizing your houseplant for about 3-4 weeks after pruning.
- Due to the reduction in foliage, the plant’s water needs will probably be lower than before it was pruned. Adjust your watering schedule as needed for the first few weeks while the plant start’s developing new growth.
Sanitizing your tools: When you have finished pruning your plant, clean your tools with a disinfectant, rinse them under the tap and dry well.
Plants not to be pruned
Majority of houseplants can be pruned, but there are some that you should avoid pruning; otherwise, they will not grow back. These include Norfolk Island pines, palms, and many types of orchids including the common moth orchid. If you cut off the tops of these plants, they will not grow back. However, you can prune off any dead leaves safely. Just avoid trimming back the growing tip of the plant.
Conclusion
Pruning is a necessary activity of houseplant care that needs to be performed regularly in order to keep them in good health. Pruning is beneficial for several reasons, including encouraging new growth, removing dead leaves which can contribute to poor plant, and improving a plant’s overall appearance.
