Guide for Planting Asclepias Seeds
We have created a simplified guide to summarize the information. Depending on the season, the method of planting milkweed seeds will vary. You can, of course, keep your seeds until the next season that suits you best for planting comes around.
Planting in Autumn (October/November)
Planting in autumn is easier, but the germination rate may be reduced.
Planting
Ideally, use well-draining soil that is light/sandy and receives sufficient sunlight. Please note that it is important to plant before the first frost.
Planting in Spring (May/June)
To plant in spring, it is necessary to stratify the seeds beforehand.
Stratification
In a waterproof container with perforated lid, mix the seeds with moist sand or wrap them in a damp paper towel.
Place the closed container in the refrigerator for at least 30 days at a temperature of 5°C.
Seed Bombs Planting Guide
Planting Period: June/July/August
Step 1 - Separation
Separate the seed bomb (the entire stick) into 4 pieces. It is possible that the bomb has already been separated during transport. This should not have any impact when planting in the ground.
Step 2 - Planting
Choose an appropriate planting location that receives full sun or partial shade. Ensure that the soil is well-prepared and free from weeds.
Take one piece of the seed bomb and gently press it into the soil, ensuring that it is partially buried. Repeat this process for the remaining seed bomb pieces, spacing them out evenly.
Step 3 - Watering
Water lightly during planting and keep the soil moist during the germination period. Be careful not to overwater the soil. It's important not to water every day as it may cause the seeds to rot and prevent them from germinating. Once the plants have sprouted, it is no longer necessary to water them regularly as rainfall is sufficient for their proper growth.
When the climate is dry and/or during a heat wave, you can water up to twice a week if needed.
For seeds planted in pots, water once or twice a week or as needed.
Frequently Asked Questions
Where should I plant my seed bombs?
It depends on the type of seed bombs you have and the seeds they contain. All the botanical information can be found on our website, on the product pages of the seed bombs: soil type, sunlight requirements, plant type, etc. In the case of milkweed seed bombs, since each bomb contains a single species, we included basic botanical information directly on the packets.
How to improve the long term growth of the seed bombs?
In terms of preparation, we've already done all we can to encourage sprouting. However, a good way to ensure longer-term plant success is to weed out a radius of at least 6 inches, but ideally 12 inches, around where each cell will be planted, to limit competition from other perennials.
Is it possible to store unused bombs?
Yes, by putting them back in the fridge as soon as you receive them. However, there is a risk of greatly reducing future germination by doing that. Explanation: During shipping, the bombs return to room temperature for a few days, which may give the seeds the signal to come out of their cold dormancy and start germinating. It's possible that by putting them back in the fridge, the seeds that hadn't yet germinated will resume their dormancy, but those that had started to germinate will probably die.
Is it normal for my seed bombs to have mold on the surface?
