We Are Eli And Kate...

and this is our garden

The darker, colder winter months are when gardeners all yearn for spring. But for the thoughtful gardeners, this doesn’t have to be a void where there is no gardening to be had. Instead, on days when we can’t be out working in the garden, we could instead be doing our preseason training… getting ready for the coming season.

So one of those jobs, is to brush up on our gardening know-how and your seed packets are just the place… and we can be indoors with a mug of tea – bonus.

We are going to decode the information on your seed packets and catalogues so we can work out exactly what seeds and plants we might want to buy or how to work with what we have. So let’s dive in and have a look at some of my seeds and discuss a few of the terms. Some are very specific and have standards or legislation behind them (like organic or GM) and others are more open to interpretation like heirloom.

F1 or hybrid varieties

I see F1 hybrid written on quite a lot of the seeds I have bought over the years, especially on my courgettes but exactly what does that mean and is there an F2? Would F2 be better?

The easiest way to understand an F1 hybrid is to think of it like this. Imagine a plant breeder sees something really desirable in a plant, but also something they don’t like, perhaps it grows really vigorously but the flowers aren’t a great colour. In one of their other plants it doesn’t grow as vigorously but the flowers are fantastic. They could take the best plant from each, and self-pollinate (in isolation from other plants) each year and, then each year, the seed is re-sown. Eventually, every time the seed is sown the same identical plants will appear. When they do, this is known as a ‘pure line’.

If the breeder now takes the pure line of each of the two plants he originally selected and cross-pollinates the two by hand the result is known as an F1 hybrid. Plants are grown from seed produced and the result of this cross-pollination should be vigorous and have awesome flowers.

Genetically Modified (GM)

These are seeds which have been created by manipulating the genes of the plants in laboratories. GM seeds aren’t licensed for sale to amateur gardeners in the EU.

Organic seed

This means the seeds have been grown from plants by certified organic means without pesticides, fertilisers or herbicides and must also be packaged without being treated with fungicides. But it’s worth noting that just because a seed packet doesn’t have a certification, doesn’t mean they aren’t organic. It simply means the suppliers didn’t pay for the certification. Many smaller companies may not have the means to pay for certification.

Annual, Biennial or Perennial

Annual plants grow, set seed, and die in a single season. Biennials take two seasons to set seed. Perennials, however, live year after year.

Determinate and Indeterminate

This is something I see a lot as I grow tomatoes and this relates specifically to them.

Determinate tomatoes (which you may also see labelled as patio or bush tomatoes) reach a certain height and then stop growing. The have multiple stems, hence being called bush, and can give high yields. I grow Sweet Million tomatoes which are this variety.

Indeterminate tomatoes keep growing and can get very tall, it’s not uncommon for these plants to reach over 10 feet in height, so they require sturdy support or regular pruning to tame the vines. You will also hear these referred to as cordon tomatoes.

Heirloom and open pollinated

An heirloom variety is just an open-pollinated variety which has a lineage that can be reliably traced back for a number of generations; it is a case of historical record rather than any difference in the genetics.

Open Pollinated or F1?
Theoretically, open-pollinated varieties are more genetically diverse so will thrive in a wider range of growing conditions and will, over the years, become more suited to growing in your garden. Flavour in open-pollinated varieties can also be better because F1 varieties tend to be grown for commercial growers where traits like uniform ripening and long shelf life may be chosen over taste. Not always but it’s something to consider.

F1 seeds, however, may be a better choice for disease resistance. For me, the conditions in Scotland are damp and cold so I see mildews and mosaic. F1 varieties allow me to choose plants which are resistant to this.

Sow and Grow – the best bit

You will also find some useful info on the back of your seed packets about when to sow your seeds and if they should be started off indoors before planting out. This is a rough guide, it’s good to think about this in terms of the weather in your area. For example, living in Scotland, I know we tend to be a bout a month behind other areas of the UK before I can get seeds germinating outdoors.

OK so you are now armed with some information on the various things you’ll read, time to get the kettle on and go look at some seed catalogues.
