Late summer · week 32

Harvest. And sow again right away.

Every bed you have cleared has one more round in it. What goes into the soil now carries you into winter.

Fill the cleared beds again
Gartenkern knows the sowing window of every plant and shows you what can still go into the bed you just cleared, from corn salad to winter purslane.
Log the harvest while it is running
Note what you carry out of the bed. From the second season on, your amounts per plant and per area sit side by side, and you can see which variety was really worth the space.
Catch late blight early
In a damp late summer it moves fast. One photo on the affected planting is enough for an assessment, with treatment steps for organic and chemical care.

Lawns in summer: heat, drought, and why brown is not dead

Mow higher, water rarely but deeply, and sit out the rest: how your lawn survives the summer heat, how to tell whether it is only sleeping, and what to leave well alone until the late summer oversow.

Lawn

Mowing your lawn properly: cutting height, rhythm and the one-third rule

Cutting too short is the most common lawn mistake. Why grass tolerates mowing at all, how the one-third rule works in practice, which cutting height suits which patch, why a sharp blade spares the grass and what to do with the clippings.

Flowering lawns and herb lawns: the low maintenance alternative

Grasses plus low, tread tolerant flowers: white clover, daisies, creeping thyme, selfheal. Four to six cuts a year at 6 to 8 cm, no feed, no scarifying. How to sow a flowering lawn from scratch or overseed it into the sward you already have.

Herbs at 35 to 40 degrees, fruit at 50 to 70, vegetables at 50 to 60: which temperature each crop wants, how an oven and a dehydrator compare, how the bend test and the snap test tell you when a batch is done, and why the sweat test in a screw top jar is what really decides how long your store keeps.

Clover and dandelion in the lawn: pushing them back without chemicals

Clover shows a nitrogen shortage, dandelion shows gaps and compaction. How feeding, cutting height, a weeding tool and overseeding put the grasses back in front, with no chemicals involved.

Garden Practice

Using the hoe properly: cut weeds off shallow instead of pulling them

Every pull tears a hole in the crumb and gives the next seeds light and room. Hoeing shallow slices the seedlings off and leaves the soil surface alone. Which tool suits when, why you hoe in sunshine, and where mulching is the better answer.
