When to Plant Sweet Alyssum

It is possible to cultivate the sweet alyssum, an annual plant with a cool growing season, in both spring and autumn. It can directly be sown outside after the spring’s last frost date. The seeds can also be started indoors around 6-8 weeks prior to the last day of frost in cold climates, followed by this the seedlings should then be transplanted outdoors once the weather is a bit warm. For a fall crop, you can plant the seeds outdoors in late summer, 6-8 weeks before the first anticipated frost and then cultivate them during winter.

How to Plant and Grow Sweet Alyssum

Although sweet alyssum plants can handle little shadow, you need to choose a spot that is full of light. It needs well-drained soil with average moisture levels to grow. To begin with, prepare the soil by weeding, adding organic fertilisers and pulling out obstacles, if any. Next, check the drainage in your soil by digging a hole and filling it with water before transplanting the seedlings. If your soil doesn’t drain, then use compost, leaf litter, and grit, such as sand, to make the soil more porous. Once you have prepared the soil, evenly spread out the seeds on the top of the soil and lightly press them to ensure they are in contact with the soil and are exposed to light. Until germination, which typically takes 15-20 days, keep the soil damp; water them only when the soil seems dry.

Where to Plant Sweet Alyssum

Before planting sweet alyssum, ensure that the soil is fertile and well-drained and that the spot where you are going to plant it has full sun and moderate shade. You can either directly sow sweet alyssum in the ground or start it indoors and move it outside later. You can grow sweet alyssum in varied places like:

• Sweet Alyssum works really well as a border plant, as an edging plant and to fill in the spaces.
• They even thrive in containers, like hanging baskets, window boxes and compact settings.
• Its low growing and spreading nature make it an excellent choice for rock gardens too.
• You can plant them in spaces between stepping stones and pavers and create a fragrant ground cover.

Proper Soil and Sunlight for Sweet Alyssum’s Growth

Sweet Alyssum requires both soil and sunlight to grow. Though sweet alyssum is adaptable to varied soil and light conditions, it favours sandy soil with good drainage, which has a pH of 6.0 to 7.0 and is slightly acidic to neutral. It even prefers exposure to mild to full sun. If the plant receives too much shade, it will become leggy and bear very few flowers. It’s crucial that you maintain moist soil throughout the growing season.

Adequate Water And Fertilisation for the Plant

Any plant, including sweet alyssum, needs water and fertiliser to survive. Here are some points you must keep in mind-

• Water them frequently during summer. Prevent the soil from drying out completely, as this can stress the plant.
• Use a balanced liquid fertiliser and fertilise them every few weeks. As a result, it will become more robust and healthy.
• Check the moisture level and make adjustments if you notice that your plant has begun to turn yellow or wilt. This can, however, be seen in plants which are drought-stressed.
• While watering the plants, try to keep the water off the leaves since this can lead to fungus and illness.
• If you come across any insects or diseases damaging your plant, seek assistance from any nearby garden centre.
• You can even pluck off the top growth of your sweet alyssum to promote bushier growth if it gets too tall or if it starts to look lanky.
• Regularly deadhead the wasted flowers to extend its flowering season.

Pruning And Maintenance

Taking care of sweet alyssum requires regular maintenance and pruning. To promote new growth and maintain their finest appearance, you need to clip them off frequently. Start by trimming back any lanky or dead stems on your plant. After that, prune it until it is just 6 inches tall. Make sure to cut an angle so that water can drain away from the plant. After your sweet alyssum is cut, it is necessary for you to fertilise it. Use a balanced fertiliser that has been designed with flowering plants in mind. Do follow the instructions on the fertiliser packaging while using it.

Deadheading your sweet alyssum plant on a regular basis is also important. Deadheading is a process of taking the plant’s spent blossoms off. This thereby encourages the plant to grow more blooms. To deadhead, all you need to do is just remove the wasted flowers from the base with a pair of sharp scissors for gardening shears.

Last, but not least, remember to water your lovelies frequently. Make sure that the soil doesn’t entirely dry out in between watering because they require evenly moist soil. While watering, avoid wetting the foliage; instead, water them thoroughly. If you give them the right attention and care, these will yield an abundance of gorgeous blooms.
