Chitting Potatoes – Seaweed Spray
When chitting potatoes, give them a light mist-spray of foliar seaweed feed every couple of weeks. Don’t over-do it, you don’t want liquid dripping off the tubers, just slightly damp. I’m not sure how it does it but it seems to help keep the tubers developing strong shoots which improves the eventual results with fewer failures on planting out.
Make Your Own Hormone Rooting Compound
Make your own hormone rooting solution. Take a young willow branch, cut into small pieces (about 1” or 2.5cm long). Place in a bowl and pour boiling water over to cover. Leave for 24 hours and then strain off into a bottle where it will keep for up to a month. Water on to the compost when propagating from cuttings.
Free Tomato Plants from Sideshoots
Free Tomato Plants – As your tomato plants grow, allow some of the sideshoots to develop until they’re between 15 and 30 cm long. Rip them off the plant and pot deeply into very moist, almost wet compost. Use a plastic bag over the shoot tied to the pot to stop them drying out and they should root in a matter of days, giving you more free tomato plants

Handle Seedlings Correctly
When transplanting always handle seedlings by the leaves, not the stem. A damaged leaf or even a missing seed leaf isn’t a problem but a damaged stem means the plant is doomed.
Move Tomatoes on Promptly
When growing tomatoes from seed move into separate pots from the seed tray within 6 days of germination. It’s been shown in experiments that the eventual plants do better than plants from seedlings left crowded beyond 6 days.

Add Lime to Compost for Brassicas
The bonus tip! If sowing or transplanting brassicas using multi-purpose compost, add a little extra garden lime to the compost. I just put a 7.5cm layer of compost in my potting tray and dust with enough lime to whiten it, like dusting a cake, prior to mixing it. Wear gloves as lime stings in little cuts. Brassicas like a high pH (low acidity) and the lime will increase the pH of the compost.
