Checking seeds for viability

After taking inventory of our seeds last week, we had to decide which seeds we were going to keep and which we needed to throw out. Each year we write the date on the seed containers, that gives us a starting point.

Some seed packs slipped through our system though and had no date on them, just the variety name. Others were getting to be a few years old meaning they were approaching the out side limits of their shelf life.  As seeds get older, their ability to germinate begins to decline. In many cases they still can be used even though they are past their prime. This week we are running germination tests on several types of seeds to see if they are something we would be able to use in the garden.

A simple germination test is easy to do and gives you a pretty good idea if it’s worth keeping a pack of seeds. To do the test,  pick ten seeds at random of one type of plant that we want to test, for example ten tomato seeds or ten onion seeds. Next take a moistened piece of paper towel. Place the seeds on the paper towel  on half of the sheet and fold the sheet over to cover the seeds. The seeds and moist paper towel go in a zip-loc bag and are sealed up. Then put the bag in a warm place to help speed up germination, we use our plant warming mat.

Seedlings are very fragile at this stage.

Check the seeds every day to see if any are sprouting. If you have the original packet, it usually tells how long it takes for germination. But when you use a warming mat with moist conditions inside the plastic bag, seeds usually sprout much quicker.

The number of sprouted seeds gives you the germination percentage. For example, if eight of the ten seeds sprout, you have an 80% germination rate.

The big surprise for us was an unmarked envelop of ‘Chadwick Cherry’ tomato seeds we found with the rest of our seeds. I don’t know where that envelop came from , maybe someone gave us some seeds a few years ago. We were expecting an low germination percentage but nine out of ten germinated. That was an excellent outcome and we’ll be growing those in the garden this season.  On the other hand, a group of onions we were looking at only had one seed sprout, we’ll toss those into the compost. Too bad because it was a pretty big packet of seeds.

Even if your seeds have a low germination percentage you can still use them, just plant extra seeds to make up the difference. For example if only half of your seeds germinate,  plant double the amount.

It’s true that you can buy fresh seeds of common varieties very cheaply. However, in our case we save quite a few heirloom and open-pollinated seeds that are not available anywhere else.Plus we don’t like to waste anything if it is still usable.

Taking seed inventory

Filed under: Catalogs,Seeds — Tags: , , , — bob @ 9:50 am

Seed catalogs have been showing up in our mailbox since before the beginning of the new year. Most of the catalogs that we regularly order from have arrived. We’re still getting a few duplicates and reminders from impatient seed sellers and some catalogs from new outfits.

I’d rather go to mailbox and see what catalog came that day than check my email and go to an online link. I realize that seed companies are so big nowadays that it’s hard for them to list everything they offer in their paper catalogs. Printed catalogs seem to get me more enthused than virtual catalogs, but that may be a generational thing.

Before finalizing our seed orders, we first like to take an inventory of what we have in storage. It’s very easy to get carried away looking through the catalogs and order things we already have on hand. And since there’s nothing much happening gardening wise right now but we’re still itching to do something, taking inventory seems to help fill that gardening urge we have right now. Maybe that’s where the expression “bean counters” came from.

Judy and I spent some time going through our pile of seed packets left over from last year. Some were not even opened, we either ran out of room or time and they never got planted. Most of the packets are partially used and contain seeds that are still viable and can planted in the garden this year. We always make sure the leftover seeds go into an air-tight container right away after we’re done planting.

While we were at it, we took the time to reduce the sheer volume of seeds that we had squirreled away. It wasn’t long ago that I had two large storage tubs of seeds that had accumulated from various people, places and projects — I’m talking about fifteen or twenty pounds of seeds in each tub.  Fortunately it doesn’t get that far out of hand anymore now that I’m culling seeds every winter.

We also have a sizable collection of heirloom seeds that were passed down to use through the years. Most of those are not available anywhere, we are part of a small handful of people keeping those varieties going. Those seeds are included in our inventory as well. We’re slowly building up the number of  those rare heirloom seeds we have. The word “rare” is often used as a marketing ploy to get folks to buy things but in this case these seeds truly are rare.

We may not be able to get into the garden yet but physically handling seeds and seed packets is a satisfying, temporary antidote to the mid-winter gardening lull.

Exploding lupine seedpods in the house

Filed under: Flowers,Native plants,Seeds — bob @ 7:43 am

I was a startled the other day as I was putting on my coat getting ready to go outside. It was quiet in the house and I was the only one home. All of a sudden I heard a snap and the clickey-clack sound of what sounded like small beads landing on the table and front entry tile floor. At first I thought maybe the cat had discovered something and was playing. I often blame the cat for things but to be honest, he very rarely is at fault.  I looked up thinking a part the ceiling lamp had disintegrated or one of the lights failed however, everything was intact.

It took a few minutes of investigating but I found out what caused the mysterious sound. Scattered around on the floor and furniture I found a whole slew of seeds that I quickly realized were lupine seeds.  Earlier this fall we collected some lupine seed pods from a roadside near us hoping to re-establish a Lupine perennis population on our property.  When we got home, we put the pods in a bowl on the table in the front entry and just forgot all about them.

Plants have many ways of spreading their seeds. For example, squirrels bury acorns, maple trees have those little helicopters thingys and milkweed uses silky parashoots that are carried by the wind. Other seeds stick to animals or pass through the digestive systems of birds and are dropped far away from the parent plant.

Here's a few lupine seeds that I found scattered around the house.

Here’s a few lupine seeds that I found scattered around the house. They are explosively thrown from the fuzzy pods when they’re ripe.

Lupine seed pods explode when they mature, throwing seeds several feet in all directions. Botanists call this spontaneous phenomenon dehiscence.  You may have seen this with other plants such as impatiens or sorrels. In this case, inside the house, it was very surprising.

I made a mental note to make sure I told my wife about it but, through the course of a busy day, I forgot about it. Later that evening when were binge watching Blue Bloods, all of a sudden we heard a snap! and the clicking sound of seeds bouncing off of the walls. Another seed pod exploded ricocheting seeds all over the place. It was then I remembered what it was I meant to tell her.

The mystery sound was solved and the cat was once again vindicated.

Saving radish seeds

Filed under: Seeds,Vegetables — bob @ 9:02 am

Our garden is big enough for things to go unnoticed plus I’m not as tidy a gardener as I should be.

This week I found a radish that had gone to seed. Somehow, one radish managed to escape being harvested with the rest of the crop. It continued to grow, flower and produce seed pods right under my nose. Apparently, it got left behind when I was pulling radishes this spring.

If it is left to grow past the eating stage, a radish plant will  eventually send up a flower stalk. The  resulting flowers are then pollinated by insects. Seed pods that superficially resemble peas or beans arise from the pollinated flowers.

It takes nearly the entire growing season for radishes to produce seeds. This one’s pods were already dry and contained mature seeds.

Pods and seeds from this radish are somewhat smaller than typical radish seeds.

I’ll save a few seeds to try out next year.

Pollen from one variety of radish often will be carried by insects to a different plant and can easily cross-pollinate another variety of radish. Radishes don’t care if they are pollinated by one variety or another. The seeds resulting from the random cross may or may not produce a desirable eating radish when planted next year.

Since the one in my garden was the only one I found, the seeds should be OK — unless the pollinators brought in unknown pollen in from somewhere else. Professional seed growers separate their different radish varieties by a half mile or more.

Anyway, I’m keeping a few seeds to try out next season.

Time for starting early seeds.

Filed under: Seed Starting,Seeds — bob @ 12:23 pm

This is time of the year when most people are counting down the number of days to the first day of spring. Gardeners  on the other hand, are calculating the number of weeks until the last frost. That date is far more useful for gardeners than the vernal equinox.

At this time, we are somewhere between ten to twelve weeks from our normal last frost. The way the winter is going right now, I’m planning on a later frost date rather than an earlier one. You have to take your best guess as to when it will be safe to plant outdoors months down the road.

The other alternative, which most people choose, is to just let the greenhouse manager worry about frost and buy your plants from him when the time comes. The problem with that is if you want a particular variety that you’ve seen in a catalog or magazine, it may not be available unless you grow it yourself.

So it’s time to sow some seeds, those that need a long time to germinate, grow and develop before setting outside in the garden. My new seed order arrived in the mail Tuesday and in it were some of those seeds I need to sow now.

The first of many seed orders.

The first of many seed orders.

I’m starting just a few vegetables this week: onions, leeks and celery.  I’ve cut back on flowers and am sowing just heirloom petunias and black-eyed Susan. In years past I would have been starting butterfly weed, sweet William, foxglove, and yarrow too.

The peak season for starting the rest of the seeds won’t begin for another three or four weeks.
