Growing Sweet Alyssum

Planting Sweet Alyssum
The perfect time to plant your new Sweet alyssum plants is typically in spring. Before getting to work, make sure that the last danger of frost has passed to maximize your chances of success. In regions with frost-free climates, you can also plant these flowers in either autumn or winter and have the same best results. Keep in mind that potted specimens will need containers that come along with one or more drainage holes at the bottom.
In terms of soil pH, sweet alyssum plants prefer those substrates that are more on the neutral to the acidic side. These companions love moisture, but they are also susceptible to root rot and do not appreciate boggy soils at all. The best way to avoid any future problems is to plant your flowers in soil that has very sharp drainage.
If you are growing your sweet alyssum plants outdoors directly in the ground, their fertilizer needs will be different from the ones of potted specimens. Unless your soil lacks nutrients, your outdoor-grown plants will not require fertilizing to grow healthy and happy. On the other hand, container-grown flowers will benefit from monthly feedings with a balanced, water-soluble fertilizer.
Likewise, you can keep your Sweet alyssum plants in bloom by deadheading them regularly. They usually set buds very quickly, so this process will reward you with an abundant carpet of flowers. Still, pruning your plants by one-third will surely be a much easier option if you are the lucky owner of many Sweet alyssum specimens.
Watering Sweet Alyssum
Like most moisture-loving species, Sweet alyssum plants will need more effort on your part when it comes to their watering routine. But do not worry, it is not as bad as it sounds! As a general rule, these stunning flowers will do well if you provide them with only an inch (2.5 cm) of water once every week.
In regions with hot and dry weather, you will have to water your Sweet alyssum plants more often than usual. Because over-watering is a common issue among these fellows, it is wise to check the soil in-between waterings. Once the top inch (2.5 cm) of soil seems dry to the touch, you can spoil your flowers with a nice drink.
Propagating Sweet Alyssum
Sweet alyssum plants tend to self-seed and spread so much that you will probably not have to propagate them very often. In fact, this particular self-seeding feature is what keeps these plants alive throughout the year. If you are not satisfied with the results, you can also start your own plants from scratch. Just make sure you also keep some specimens for your family or friends!
Starting sweet alyssum plants from seed is a fast and easy process. All you have to do is to collect the seeds from your flowers and sow them in the soil. You can start your plants from seed outdoors directly into the ground, but only once the soil feels warm to the touch. If you prefer to do this indoors, you must start them about eight weeks before the last frost date.
Make sure you plant the seeds so they make good contact with the substrate while still receiving bright, direct light. Provide your Sweet alyssum seeds with water regularly to maintain their growing medium constantly damp. Once germination occurs, usually in a month or so, you can transplant your potted seedlings in their permanent location. But do not transplant them until the last threat of frost has passed.
In Conclusion
Being so alluring, easy-going, and having so many cultivars to choose from, it is almost impossible to resist Sweet alyssum plants. These flowers can fill any dull spot from your garden or home with minimal effort on your part. But you will see all this for yourself only if you give them a chance!
