The Advantages Growing Your Own Seedlings

Growing your own seedlings offers many advantages over commercial seedlings or direct sowing of seeds.   This page looks at the advantages of growing your own seedlings, as well as things to consider before you start growing your own seedlings.

The advantages of growing your own seedlings

The advantages of planting seedlings can be summed up with the acronym PEAT

Protection

It’s easier to protect seedlings from pests because they are concentrated in seedling trays and are mobile, meaning they can be moved to another site if pests are eating the seedlings.

Environment

Easier to control the soil quality (high quality seed raising mix) and heating/cooling (both with glass/plastic domes) and artificial heating devices.

Accuracy

You can place seedlings precisely where you want them instead on the somewhat hit and miss method of sowing directly into a vegetable bed.

Turnover

While a crop in the ground is maturing you can be already growing the seedlings for the replacement crop. Once the crop in the ground is harvested and manured you can immediately plant your seedlings that have been growing, thus reducing the turnover time (the time from planting through to harvest and then making the bed ready for the next planting) by around four to six weeks.

planting commercially grown seedlings

The Accuracy and Turnover points above also apply to commercially grown seedlings, however commercial seedlings cost a lot more than home grown ones and, when compared to the variety of vegetable seeds the market offers. the range of seedlings available is much smaller.    For more information on commercially grown seedlings see: Using Commercially Grown Vegetable Seedling.

Vegetable seedling planting suitability

Some vegetable seedlings, such as lettuces and broccoli, transplant easily.  Others, such as pumpkin and corn, do not respond well if their roots are disturbed when transplanted and are best grown in single cell seedling trays or sown direct.  Yet others, like carrots, respond very poorly when transplanted as seedlings and are best sown directly.    For details of which vegetables are best grown as seedlings and which should be sown direct see: Seedling Planting Suitability Chart.
