Most gardeners typically buy plant seeds and sprays only when needed during the season. But why not make these investments earlier, during the dormant period, when these products are already in stock and not yet picked over?
Why Is It Beneficial to Buy Seeds and Sprays Off-Season?
Most gardeners typically purchase plant seeds and sprays only when needed during the season. But why not make these investments earlier, during the dormant period, when these products are already in stock and not yet picked over?
The winter period is generally quieter, giving us more time to plan what we'll grow next season. For those who enjoy gardening as a hobby, making these considerations is a welcome diversion during a time when we otherwise can't devote much attention to the garden.
Cost-Effective Shopping
During the off-season, prices are lower than during the peak season. This is due to several factors, with the difference being most noticeable for plants with higher storage requirements. Storage costs increase over time. For example, seed potatoes are 1/3 cheaper in autumn than they will be in spring. Additionally, sales turnover is lower during the off-season, so retailers try to attract customers with more favorable prices or various promotions. No garden and growing enthusiast would be offended by a gift in the form of interesting seeds, so why not think about the garden even in winter and try looking for Christmas presents in this area for a change?
Diverse Selection
Almost everyone has experienced finding that when it's time to start sowing, stores no longer have such a diverse selection of varieties. However, with earlier purchases, this won't happen. Usually, even less common varieties that sell out quickly are available.
What to Focus on When Choosing Seeds and Sprays Off-Season
Choosing the Right Package Size
This question arises especially with plant protection products, but also with seeds. The rule here is that the smaller the package, the more expensive the actual spray or seeds are compared to larger packages. It definitely pays to buy products we know will be needed in appropriate quantities. Your own experience with the consumption of these substances, based on the size of the treated area, is the best guide here.
Regarding the quantity of seeds to purchase, again multi-year experience is the best helper. A certain clue can be the number of seeds in the package, which is sometimes stated (mainly for more expensive seeds), or the technical term Thousand Seed Weight, known as TSW. In better literature, this term is mentioned when describing individual species.
For illustration, for all brassicas the TSW is 3-5g, so if a packet of kohlrabi seeds contains 0.5g of seeds, then there are approximately 100-150 seeds in it. Information about TSW can be found online for more common plants.
For some plants, you can also base your decision on the fact that they can be sown multiple times per year, such as radishes or spinach. Therefore, in this case, it pays to buy several packages at once.
Expiration
Germination capacity for seeds and shelf life for preparations is not unlimited, usually guaranteed for 2 years. If we purchase before the new year, it's good to check the expiration of seeds and preparations, which is typically dated until the end of the calendar year. This way, our purchased goods could expire by spring. After expiration, seeds usually experience reduced germination. For some species this is more noticeable, for others less so. For example, umbelliferous plants lose germination after just two years from harvest, while cucumbers can maintain germination even for six years with proper storage.
Storage
Previously purchased seeds and preparations must be stored longer until use. While seeds only need a dry, cool place such as a pantry, tubers like the previously mentioned potatoes are more difficult - they take up more space, require temperatures up to 15°C and also need certain humidity. So if we don't have suitable storage spaces (e.g. a cellar), it's better to purchase tubers in spring.
Plant protection products must be stored separately from food, preferably in dry, cool and dark conditions, except for biological preparations which may have different requirements. It's always worth following the package instructions.
