Good Companions

Dan and Julia delve into the subtle, little-understood subject of companion planting, revealing which plants get along well and which really don’t! Dan describes three fantastic new tools that have just joined his Signature range, and Julia explains the Three Sisters method of growing beans, squash, and sweetcorn together.

Dan & Julia's Favourite Plant Companions:

1. Plant basil near or at the base of tomatoes to ward off white fly
2. Grow nasturtiums as sacrificial plants to attract black fly
3. Position French marigolds attract aphids from cucumbers and runner beans
4. Tansy deters ants due to its spreading nature underground and planted under fruit trees; it helps deter flies. (It is, however, toxic to pets.)
5. Plant strong-smelling herbs such as sage and parsley to keep aphids away
6. Black mint or Hucatay, Tagetes minuta is part of the marigold family. It is an excellent companion plant for greenhouse veggies such as cucumbers, chillies, tomatoes, peppers and aubergines. The pungent smell helps repel and confuse insect pests through the flowers and leaves and releases anti-nematode compounds into the soil. 
7. Grow strawberries beneath grape vines as they succumb to vine weevils first, giving you a fighting chance to save your grapes. Strawberries also indicate if scale insects are a problem on vines by getting covered in sooty mould first.
8. Grow chamomile amongst other plants to keep fungus, mildew, mould and blight away.
9. Plant onions or garlic between carrot rows to deter carrot root flies.
10. Grow lavender alongside carrots and/or leeks. The scent attracts many pollinators and keeps pests at bay.
11. Plant borage and strawberries together - borage attracts pollinators and has a mild cucumber scent; this will help keep predators off the strawberries and improve their flavour.
12. Plant calendula with courgettes as the calendula protects the courgettes from slugs and snails, in theory!

Dan's Product Picks:

1. Signature T-handle Spade - perfect for border work, planting roses and perennials
2. Signature T-handle Fork - great for working on your hands and knees in beds.
3. Signature Japanese Weeding Hoe - great for weeding raised beds.

Gardening Jobs for the Fortnight Ahead:

• Make a final sowing of summer annuals like cosmos and zinnias.
• Sow biennials, including sweet williams, foxgloves, hesperis, honesty, stocks and wallflowers.
• Sow broccoli, kale, spinach, and a final batch of runner and French beans.
• Don’t let containers dry out - bright and breezy weather dehydrates plants very quickly.
• Deadhead roses to keep them neat and tidy and encourage further flushes of flowers.
• Pinch out dahlias, fuchsias and coleus to encourage bushy growth.
• Give wisteria its summer prune, cutting all the long side shoots back to 20cm.
• Prune late-spring or early-summer shrubs after flowering, thinning out the flowered stems.
• Install a water butt if you don’t already have one.
• Harvest salads regularly.
