Seed Club - July


Whether you’re new to growing from seed or more experienced, our Seed Club offers you great deals on seeds, timely reminders and practical seed-sowing advice. Every month, Sally Nex will be guiding you through the key sowing and growing jobs.


This is what it's all about. That moment when the hard work is mostly done, you can ease back a bit and simply enjoy your garden. It's quite a sight. Verbena flowers dancing on wiry stems among the cosmos, tomatoes reddening on the vine, zinnias and larkspurs to pick for the house, and all those French beans to freeze...

  • Start feeding tomatoes the moment you start seeing flowers, using a capful of high-potassium liquid fertiliser in the watering can once a week to encourage bumper crops of fruit
  • Cut-and-come again lettuces you've been picking since spring will soon be starting to flag, so sow a fresh batch now and they'll be just ready in time to take over. If it's hot, sow in the evening and keep the trays in a shady place so they never dry out
  • Sow parsley direct into roomy pots, pop in a shady spot to germinate, and you'll have fresh herbs for your windowsill to pick through autumn and winter
  • Once runner beans start cropping, pick them over every two or three days to enjoy the beans while they're still young, tender and stringless. Picking regularly also keeps plants at the peak of production
  • Sow 'understudy' plants like beetroot, lettuce and chard in modules in a cold frame. Then once they're seedlings, simply drop them into any gaps which open up so you can keep picking without a pause
  • Pull out spring-sown chard once it starts to form thick central flowering stems as the leaves are now past their best. Tickle in some compost to reboot the soil and sow a new batch straight away to take you through autumn
  • Open greenhouse doors and windows wide in dry weather to keep plants cool and attract in pollinating insects. But remember to shut it up again if it rains, to keep out the dreaded blight
  • Hang yellow sticky traps among greenhouse plants. They make great early warning systems for the arrival of pests like whitefly and greenfly, as you'll see them on the sticky traps long before you spot them on your plants
  • You can grow kale as an unusual and flavour-packed cut-and-come again leaf to snip while still tiny and tender for autumn salads. Sow now into broad, shallow drills, scattering seed quite densely: they're ready to pick once seedlings are about 10cm tall
  • In a dry spell, make your watering more effective by heaping up little ridges around thirsty plants like tomatoes and runner beans. These hold moisture by the plant till it soaks in, instead of letting it run away across the surface of the soil

Flower jobs for July

  • Pick larkspur flowers regularly and they'll respond by producing more buds lower down the plant, extending the flowering period by weeks
  • Sow a new batch of cosmos now and you'll have seedlings to plant out just as the current display is fading, giving you flowers till the first frosts
  • Pinch out the growing tips of cleome plants, back to the first pair of leaves, to encourage them to bush out and produce loads more spidery flowers
  • Inspect leaves regularly for signs of aphid colonies on the undersides. They'll suck the life out of your plants if you let the numbers build up, so squash between finger and thumb while there are only a few
  • Remove the curly tendrils from sweet peas as they grow, to stop them wrapping themselves around your nice straight flower stems and twisting them into unpickable knots
  • Collect the seeds of Nigella (love-in-a-mist) for sowing next year. Wait till seed heads are crispy and brown, then pop a paper bag over the top. Snip the stem and turn the whole thing upside down so the seeds empty out into the bag
  • Pick and dry the flowers of Verbena bonariensis and they'll look gorgeous all winter. Tie in loose bunches and hang upside-down somewhere cool and airy for a fortnight
  • As flowers start to form on late-blooming rudbeckias and zinnias, give them a boost with some liquid seaweed fertiliser added to the watering can once a week
  • When cutting zinnias, snip the stem away just above the leaf node below, This encourages dormant buds to break and you'll get double the flowers in a few weeks' time
  • Keep up with watering, especially in dry spells. A thorough soaking every week to ten days is miles better than a daily sprinkle, as the water soaks right down into the rootzone rather than just evaporating off the soil's surface

Seed Club - jobs for August

I'll be fending off the August doldrums by planting out all those precautionary late sowings I've been making, filling the gaps left by all that enthusiastic summer picking and making sure the show goes on right through into autumn.
