Clerodendron, Large foliage, abundant flowering and attractive berries

There are many, many varieties of Clerodendron - including Clerodendrum Bungei, also known as the "Clergy Tree". It is a beautiful looking shrub. Some varieties reach over three meters in height. The original foliage is often very large, giving the shrub the air of an exotic plant. Flowering is abundant but rather short from August to September, the flowers appear on the shoots of the year. Blue berries set in a red calyx follow the flowering (photo below Clérodendron trichotomu). The shrub likes sunny locations and rich, cool soils. The foliage has a peculiarity, it produces a pungent odor, quite unpleasant when crumpled. The flowers, on the other hand, give off a scent reminiscent of jasmine. A clerodendron will share the place of a backdrop in the company of sumac or shrub lavatera ... But can be planted solo in the garden!

Sowing and planting sorrel: when and how?

Sorrel is a vegetable and condiment plant, aromatic, herbaceous, with an acidic flavor that some people dislike but that others greatly appreciate, qualifying rather its tangy and lemony taste. The tender green leaves in the shape of a spearhead are used sparingly, raw in a mixed salad, or cooked in soup, in sauce to accompany fish or in omelet. It forms a perennial tuft which must be renewed before the heart lignifies itself after a few years.

Multiplication of chestnut by top grafting

  • You can multiply the chestnut by grafting. If a chestnut does not produce good fruit, but has a good root system, it can be felled.
  • The following year, it will produce suckers around the stump.
  • Select two or three that we will graft.
  • The grafting consists of cutting the reject to 1.20 m in height.
  • Position a graft taken the previous year on the previously cut reject.
  • Of the two or three grafts performed, keep one that is developing well.
  • It needs a space of 100 to 120 m2 depending on the depth of the soil.
  • Plant several chestnut trees, including two different varieties to ensure good pollination and fruit production.
  • The chestnut likes loose soil rich in humus. Give it organic manure (eg composted manure) to improve the texture of the soil and feed the tree.

Where to plant the beans?

Vicia Fava particularly appreciates the proximity of the tomato. It also likes squash, cucumber, eggplant, zucchini and strawberry. On the other hand, she hardly appreciates the company of garlic, onion, leeks and chives.

In order to avoid the spread of diseases in the vegetable garden, it is recommended to carry out a crop rotation over 3 years. After the beans, the ideal will be to grow leafy vegetables (cabbage or salad) the second year, then bulb vegetables such as onions in the third year.

Replenishing your lawn

When to sow reline grass? In this case, the correct period is the same as for a conventional lawn. It is therefore necessary to sow in spring or autumn when temperatures are above 10 ° C and it rains regularly.

Choose a mixture of seeds close to your initial choice. Finally, proceed as when you planted your lawn for the first time: aerate the soil by scratching it or
with a scarifier, roll, sow, roll again and voila, voila!
