How to Grow Alstroemeria in Pots
There are a lot of things to keep in mind when you are trying to grow alstroemeria in a pot. Even though these plants find their most suitable growing circumstances when they are planted directly on the ground, some smaller versions of them can thrive in pot gardens as well. Throughout this article, gardening enthusiasts will get all the important information about growing alstroemeria in pots. Besides, they will also know some tips on how to take care of these plants in different seasons. Stick with us until the end for more.
1. Choosing a Container
Choosing the right containers will be crucial when you are planning to grow alstroemeria in pots. The container you are choosing must have a great drainage system to send the excess water out from the base.
You should know that these Peruvian lilies grow better when they get a chance to spread their roots freely. Therefore, you should always go for a wider container with more depth. A container 40 cm in diameter can be perfect for mature plants. However, make sure not to over-pot the smaller plants, as that might cause water clogging.
Always choose a container that is slightly bigger than the recent root system, and you should keep moving to a slightly larger container every time.
2. Choosing the Soil
Choosing the right kind of soil is also very important when you are trying to grow alstroemeria in a pot. One should always opt for a soil mix that comes with an improved drainage system for the plants. Using propagating bark can be an amazing solution when you are trying to choose the best soil for better drainage. Propagating barks are also perfect for mulching the top of the pots, and you can retain the moisture and keep the weeds down.
3. Potting the Plant
Alstroemeria is often potted in containers at the beginning of the spring, and you need to repot the plants in a larger container every two years or so. It is best to pot only one plant in a container, as alstroemeria plants can grow quickly. Potting multiple plants in a pot can become pretty congested for the plants.
However, growing alstroemeria in a large container along with other plants can be fine as long as you repot the plants every couple of years. In that case, you need to ensure that the other plants in these containers are fond of the same soil and weather conditions, like alstroemeria. Most important of all, make sure these other plants are not overly competitive.
Planting Alstroemeria in Pot
Next is planting alstroemeria in the pot. There are a few things you need to remember while planting alstroemeria plants in the container we have prepared so far.
- First things first, always handle the plants and the tubers with gloves. The sap of these plants can cause irritation in humans.
- As we have already said, alstroemerias are the flowers of summer. Therefore, you need to plant it in early spring in a sheltered, sunny spot.
- Space these plants about 45-60cm apart while planting. The planting hole needs to be 20 cm deep.
- When you plant them deeply, the tubers will sit below the normal level of soil frost. This can protect them and help them be strong and established. You can also mulch the clumps in autumn and winter to protect these plants even further for better results.
- Planting alstroemerias inside a greenhouse can also be a great idea. Pot these up in five-litre pots in gritty compost. Also, keep the plants frost-free and start feeding them as they start shooting in spring for an almost continuous flower harvest.
This is the best way to plant alstroemeria in a pot. Now that you have successfully potted the plants let’s move on to how to take care of them as they start growing.
Taking Care of Alstroemeria in Pot
Alstroemeria plants, when you plant them properly and take care of them properly, can add a little pop of colour to the gardens. With the right care, these plants can bloom for years. However, even though many people get the planting part right, taking care of these beautiful Peruvian lily plants is even more important. Here are some tips to help you take care of these plants properly.
1. Watering
Watering alstroemeria plants regularly during the prolonged dry spell. However, these plants are relatively more drought-tolerant. If you are plating alstroemerias in a greenhouse, it might require frequent watering due to their lack of exposure to natural rainfall and limited volume of soil.
2. Fertilising
Adding a slow-release fertilizer in the spring can ensure better flowering. Try to opt for high-potash fertilisers for any container-grown alstroemerias, like tomato feed.
- Seaweed plant fertilizer promotes strong growth, increased crop yields and lush foliage
- Multi-purpose fertiliser which includes extra iron and plant based amino acids that feed garden...
- Suitable for use on lawns, fruit, vegetables, flowers, trees and all garden plants
3. Staking
Alstroemerias can reach over 60 cm. Flowers might make the top of the plant heavy. Therefore, unless you find a sheltered spot, the taller varieties will need staking. That might be the only way to stop the plants from collapsing in the wind or rain.
4. Deadheading and Harvesting
You should keep harvesting the flowers and deadheading the faded ones. The best way to do that is to pull them out instead of cutting the stems. You should also hold the lower part of the stem. Doing this the rough way instead of cutting the stems might provoke the plant to flower more.
5. Dividing
Once the plants have settled in for a few years, alstroemerias spread below the ground. Propagate the plants by division every one to two years to avoid congestion. The roots of the plant are fragile, and you need to lift them and divide them with care before replanting them immediately. Do the division in the early autumn for better results. Divide the clumps and replant them in another pot.
6. Overwintering
Alstroemerias have tender tubers. These plants easily become hardy as they get established in mild autumns and winters. It might take great mulch in the colder months, and it might emerge again in the next season.
You should mulch deeply for the first few winters. You can give them some amazing chances, especially when you live in the colder parts of the country.
