Growing and taking care of lilacs make a pretty simple hobby. However, knowing how to do things perfectly does better. Read on to learn more about lilac care.
Planting Lilacs in the Garden
Suppliers often ship (Syringa vulgaris) lilacs as bare root plants so it may surprise you upon receiving them. The plants may appear dead, but the video below shows its dormant or sleeping state.
To wake them up, soak the roots in water for about 10 minutes. Some other important things to keep in mind when planting lilacs include the following:
- Common lilacs need quite a lot of sun. Find a place where you get sunlight in abundance, and it will help them grow better.
- Apart from sunlight, lilacs need space. They can even grow into small trees if given enough room. Always provide them a good amount of space.
- Lilacs also require proper water drainage to thrive.
- When planting, place the root ball close to the surface of the well-drained soil and tamp down firmly. Plant them 2–3 inches deep into the ground if you received the lilacs in the form of bare roots.
- Water the plant thoroughly.
- Put them at least 10–14 feet apart if you like to plant more than one lilac bush.
Planting Lilacs in Containers
Growing lilac plants in a container may appear as a form of bonsai. Though some of the rules match with container grown lilacs such as abundant sun and good drainage, keep in mind about these additional requirements.
- Choose dwarf lilacs for container gardening. Some famous dwarf lilacs include the Purple Gem and Pixie. You may also pick the dwarf korean lilac tree (Syringa meyeri), attractive lilac shrubs which will add grace, beauty, and fragrance to your garden.
- Choose a sturdy container big enough to hold the root system of a fully grown plant.
- Try not to move the pot from its original position once the plant established its roots
- Choose a high-quality, well-drained soil with a good mixture of compost included.
- Plant lilacs 3–4 inches deep and tamp down firmly.
- Water the plant thoroughly.
Caring for Lilacs in the Garden
Although lilac trees do not need much attention while growing, a small amount of care will help them grow to their full size and produce more of those lovely blooms. Some of the steps to take while caring for lilacs are as follows:
- Apply a good layer of mulch every year to retain moisture and control weeds.
- Wait until the top becomes thoroughly dry and then water the common lilac trees well.
- Fertilize lilacs very sparingly. A good fertilizer in late winter will serve as enough for the rest of the year.
- Pruning lilacs correctly tops the list of to-dos when it comes to taking care of lilacs. Trim them once the blooms ceased. This helps them grow back stronger than before.
- Deadheading lilacs will help the plant to produce more flowers. Moreover, it will make the plants look even better.
- To improve flowering of lilacs, don’t let grass grow near their roots.
Caring for Lilacs in Containers
- Lilacs grown in warm climatic zones can stay outside throughout the year.
- When growing lilacs in freezing regions, bury containers in the soil to promote more budding and growth.
- Make sure the root system of your lilacs can move freely. If movement becomes restricted, they will not bear many lilac flowers no matter how good the leaves looks.
- Keep the container in a place where it can receive at least six hours of sunlight.
- Watering lilacs in a pot may seem like a delicate task. This is due to excess water may damage or kill them. Only water when the soil appears dry and water for about one inch deep.
- If you see roots coming out of the water drainage holes, this signals the time to root prune the plant.
With these care and planting tips, anyone can enjoy beautiful lilacs and feel as youthful as the blooms!
Tips for Long Lasting Lilacs
With lilacs blooming in many areas of the country, what better time than now to make sure they stay blooming as long as possible.
According to horticultural expert Paul Parent, the below tips on caring will help get the most and prolong the life of your lilacs.
- Lilacs grow best with a minimum of 1 inch of water per week during the hottest months.
- Do not over-fertilize or they will not bloom. Over-fertilized plants only grow nice foliages but without the fragrant flowers. At springtime, feed your lilacs with something like Plant-Tone.
- Lilacs plants love sweet soil. This means they grow well with pine trees or oaks nearby. During the beginning of spring, add limestone, wood ash, or similar products at a rate of 2-3 handfuls per 3 feet tall or spread of the lilac.
- Lilacs bloom on old wood. All things considered, you should prune in the spring as soon as the flowering ends. If you wait for too long, you will remove the new flower buds for next year.
- While pruning, remove the dead wood and the oldest canes. Cut those right down 5-10 inches from the soil.
- Each year, cut out 1/2 – 1/3 of the old wood to maintain reblooming lilacs. Cut the tallest parts back to about 5-6 feet.
- Hardy lilacs will grow in Zones 3 – 7 but don’t grow well in areas with the warmest climates
Tips On Pruning Lilacs For Decades Of Flowers
The lilac bears beautiful and fragrant flowers. As plants grow taller and its stems become mature, the flowers will appear smaller, fewer, and more “invisible.”
