Ordering seeds from mail order catalogs is a popular way for gardeners to access an extensive variety of plants, including heirlooms and rare cultivars. However, many gardeners encounter issues that can affect germination, growth, and overall success. This list covers common problems with seeds bought through catalogs and practical fixes for each, helping both novice and experienced growers get the most from their mail order seed purchases.
1. Low Germination Rates
One of the most frequent problems with mail order seeds is poor germination. This can result from old seeds, improper storage by the supplier, or seeds that were not fully mature when harvested. To fix this, always check the seed packet’s harvest year and opt for companies that guarantee germination rates. You can also perform a simple germination test by placing seeds on a damp paper towel before planting to estimate viability.
2. Seeds Arriving Damaged or Crushed
Occasionally, seeds arrive crushed or broken due to rough handling during shipping or poor packaging. Damaged seeds often fail to germinate or produce weak seedlings. To avoid this, choose vendors known for sturdy packaging and consider adding a note requesting careful handling. If seeds arrive damaged, contact the supplier for a replacement or refund, as reputable companies will typically stand behind their products.
3. Incorrect or Misleading Labeling
Some mail order seeds come mislabeled or have vague descriptions, leading to surprises when plants grow. This issue is especially common with heirloom varieties or seeds sourced from multiple growers. To mitigate this, buy from well-established seed companies with clear, detailed descriptions and photos. Additionally, cross-reference seed names with trusted gardening databases or forums to confirm authenticity.
4. Poor Seed Storage Conditions Before Shipping
Seeds are living organisms that require proper storage to maintain viability. Exposure to heat, moisture, or light before shipping can reduce seed vigor. When ordering, look for companies that describe their storage methods, such as refrigeration or sealed packaging with desiccants. Upon receipt, immediately transfer seeds to airtight containers in a cool, dark place to preserve freshness.
5. Seeds That Are Too Old or Past Their Prime
Seeds lose viability over time, and some mail order catalogs might sell older stock without disclosure. This leads to disappointing germination rates and wasted money. Always check the seed packet for the pack or harvest date and avoid seeds older than 2-3 years for most vegetables. If you suspect old seeds, perform a germination test or purchase smaller packets to minimize risk.
6. Inconsistent Seed Quality Within a Packet
Sometimes seed batches contain a mix of viable and non-viable seeds, or seeds of uneven size and maturity, which can cause uneven germination and growth. This inconsistency often comes from less careful seed cleaning or grading by the supplier. To address this, consider pre-sorting seeds by size or density before planting and sow them thinly to allow room for stronger seedlings to thrive.
7. Seeds Contaminated with Weed Seeds or Other Debris
Occasionally, mail order seeds may contain unwanted weed seeds or foreign matter, especially if the supplier does not thoroughly clean their seed stock. These contaminants can introduce weeds or diseases into your garden. To minimize this risk, buy from reputable companies with strict quality control and inspect seeds visually before planting. If contamination is suspected, sow seeds indoors and transplant seedlings after confirming their identity.
8. Seeds Not Adapted to Your Climate or Growing Zone
Seeds sourced from distant regions may not perform well in your local climate or USDA hardiness zone, leading to poor germination or plant stress. Mail order catalogs often offer exotic or unusual varieties without clear guidance on suitability. Before purchasing, check the seed’s recommended growing zones, day-length requirements, and heat or cold tolerance to ensure compatibility with your garden conditions.
9. Lack of Detailed Growing Instructions
Some mail order seed packets provide minimal or generic planting information, which can confuse gardeners unfamiliar with a particular species or variety. Missing details such as seed depth, soil temperature, or germination time can lead to failed starts. To fix this, research growing guides from trusted sources like the USDA, extension services, or seed company websites, and keep notes for future reference.
10. Delayed Shipping Leading to Late Planting
Seeds arriving late in the season due to shipping delays can shorten your growing window, especially for annual vegetables and flowers. This is a common issue during busy spring months or with international orders. To avoid this, place orders early—ideally in late winter—and choose vendors with reliable shipping histories. If seeds arrive late, consider starting them indoors or using season extenders like row covers to maximize growth time.
How to Choose
When selecting seeds from mail order catalogs, prioritize companies with strong reputations for quality and transparency. Look for clear labeling with harvest dates, germination guarantees, and detailed growing instructions. Consider the seed’s suitability for your USDA hardiness zone and local climate. Smaller packets from multiple vendors can reduce risk while allowing variety. Finally, check reviews and gardening forums for real customer feedback on seed viability and supplier service.
Frequently Asked Questions
Q: How long do mail order seeds stay good?
Most vegetable seeds remain viable for 2-5 years if stored properly in cool, dry conditions, but germination rates decline over time.
Q: Can I trust germination guarantees from seed catalogs?
Reputable companies often guarantee germination and will replace or refund unsatisfactory seed packets if you provide proof of planting under recommended conditions.
Q: Should I start mail order seeds indoors or direct sow?
It depends on the plant species and your climate. Many seeds benefit from indoor starting to extend the season, especially in cooler zones.
Q: What is the best way to test seed viability?
Place 10 seeds on a damp paper towel, keep warm, and check for sprouting over 7-10 days. The percentage that germinate estimates viability.
Q: How can I avoid receiving poor quality seeds?
Order from established seed companies with positive reviews, clear packaging dates, and germination guarantees. Avoid very cheap or unknown sources.
Q: Are heirloom seeds more prone to problems?
Not necessarily, but heirlooms may have less uniformity and require more care. Buy from trusted heirloom specialists to reduce risk.
Final Thoughts
Mail order seeds open up exciting possibilities for gardeners but come with challenges like low germination, damaged seeds, and mislabeling. By understanding these common issues and applying the fixes outlined here, you can improve your chances of growing healthy, productive plants. Careful selection of seed suppliers, proper storage, and a bit of testing go a long way toward a successful garden season. Happy planting!
