In spring you raise plants to warm them; in summer, to cool them 🌻 July's two jobs

In spring you raise plants to warm them in summer to cool them

🗨️ "July is just hot. There's nothing to do."

🗨️ "I'll start the winter crops when it cools down."

🗨️ "September always feels a bit thin."

Hello, I'm Eiko. Eight years of growing vegetables organically and without pesticides, and a teaching licence in science.

The monthly instalment — July. The hardest month of the year, and not only a month of endurance.

The point, up front:

July has two faces.

One is protecting the summer crops from the heat. The other is starting the autumn and winter ones ☺️

① The month of protecting

Diagram: July has two faces

What this diagram says

  • July has two faces
  • The month of protecting — water the paths, not the plant / straw on top of the mulch / shade netting for part shade / pick every day / pull finished plants the same day
  • The month of starting — July: sow and raise plants → September: plant out → winter

Five things, all covered before:

Those five carry you through the worst of the summer. A plant looked after in July endures August and fruits again in early autumn. Neglected, it's finished before August starts.

② The month of starting

July is when the autumn and winter crops begin.

I assumed for years that winter crops started when it cooled down. They don't.

Work backwards from planting out

Of the crops planted out in early autumn, the ones that take a long time to make a plant start now. Two in particular:

Both are slow to reach planting size. Planting out in early autumn means sowing in July.

Same structure as April: bring the sowing and raising forward; don't rush the planting out. Count back from the planting date rather than looking at the calendar, and the year starts to turn over properly.

The same word, the opposite purpose

Diagram: the same job with opposite purposes

What this diagram says

  • The same job, opposite purposes
  • Spring raising = to warm — germinate them on top of the fridge / hold the right temperature in a small frame / get them to planting size before the heat
  • Summer raising = to cool — keep them somewhere cool / let air through / soften the sun

In spring, raising plants is a set of tricks for adding heat — germinating them somewhere warm, holding the temperature in a frame.

July is the reverse. Too hot to germinate; too hot for a seedling to grow.

So summer plant-raising is a set of tricks for removing heat:

The same word, the opposite intention. Which made something click for me: raising plants simply means "you decide the temperature." In winter you raise it; in summer you lower it. That's the whole difference.

Raise them in the shade, not in the bed

Don't sow direct. Raise them somewhere cool and airy and shaded:

Modules and pots let you choose the location — which is the whole advantage of raising plants in summer.

If you must sow direct

Sow into an unprotected July bed and very little will germinate. The surface is simply too hot.

Remember that germination temperatures refer to soil temperature, not air temperature — and July soil is above the right range for most vegetables.

North-facing is the place. It gets the least direct sun and stays coolest — the same spot that's useful in winter for freezing container compost is useful now for the opposite reason. Lend the coolest place in the house to your seedlings for a few weeks.

Filling the September gap

There's an old word for it: the gap season — the interval when the previous crop has finished and the next isn't ready.

So early autumn produces less, and a lot of gardeners conclude they had a bad year. It isn't a bad year. It's the gap. Growers have struggled with it for centuries, which is why it has a name.

The remedy is to prepare for it now: sow in July the things that will crop in early autumn.

Knowing the gap exists stops you feeling defeated by it — and sowing now means it doesn't happen.

What to sow and plant

Diagram: what to sow in July

What this diagram says

  • What to sow and plant in July
  • 1 Raising cabbage and broccoli — counted back from an early-autumn planting; in cool shade
  • 2 Edamame (July sowing) — left to mature it becomes a soya bean
  • 3 Carrots (summer sowing) — the first week until germination is everything. Never let it dry
  1. Cabbage and broccoli — raised in cool shade, for planting out in early autumn
  2. Edamame — a July sowing crops in autumn, and left to mature it becomes a soya bean
  3. Carrots — the summer sowing. The week until germination is the entire job: never let the surface dry. Fleece over the row and water through it
  4. Molokhia and water spinach — the two leaf crops that produce in real heat
  5. Mooli and turnips, late in the month, in cooler regions

Priorities for July

If the heat means you can only do some of it, in order:

  1. Water, early in the morning, on the paths
  2. Pick everything that's ready
  3. Pull anything finished
  4. Start the cabbage and broccoli in the shade
  5. Everything else

And go out in the early morning. The garden can wait; you shouldn't be in it at midday ☺️

To sum up

You don't have to do all of it. Put one tray of cabbage seed somewhere shady this week. That's December's dinner, started 🌻
