How quickly do I need to plant bare-root silver birch trees in winter?

As I recall, you're in the UK - the ground is not yet frozen, so get them in asap, having first dug the whole area over thoroughly, not just digging holes and inserting the trees, especially if you ...

What should I do with unplanted narcissus/daffodil onions outside of planting season?

Plant them now, although I doubt you'll get any flowers this year. Don't remove the leaves before they completely fade. You can keep the bulbs in the ground without taking them out every year until ...

Carnation photoperiod responsive stage?

Adequate photoperiod is not enough for carnations (Dianthus caryophyllus) to start flowering. They need a few months of cold environment like I said in your other question, about 5°C (41F°) for 10 ...

Can garlic be planted in the winter, in hardiness zone 5 inland northeast USA?

Since garlic is recommended to be planted about 6 weeks before freezing, you've already passed the (proper) opportunity to plant them I'm afraid (why would you want to plant them in the frozen soil ...

What should I do with my daffodil bulbs after having removed them?

The easiest way to store them is to put them in the ground. However, if for some reason, you can't plant them again, wash them thoroughly, keep them in a well ventilated area for a week or so, and ...

Can I plant garlic in the spring?

I've done it both ways (also zone 4) and always get better production if it's in the ground over winter (even if gotten in very late in the fall, or even early in the winter). Part of the problem is ...

Can I plant garlic in the spring?

Growing fava beans when too hot for flowering; since perennial, will they eventually fruit later in the year?

In temperate UK, fava beans (or "broad beans" as we call them) are planted either in fall or spring. Both will crop in the summer after planting. The reasons we plant the previous year are mainly to ...

Transplanting Tulips from Northern to Southern Hemisphere

Tulip bulbs need a cold period, so here in Europe they should be put in the ground before winter (let's say November). Then after the winter they will grow in Springtime. So if you want them in the ...

Keep them out of hot direct sunlight until they are bigger and more robust - a little early morning or evening sun should do no harm. When they are bigger, you will likely need to pot them up into ...

For a newly built apartment, when and how do I start developing what's basically a building site into a healthy soil for a variety of plants?

You can't usually just "dump topsoil" on top of what is already there, because if you add enough topsoil to make any difference (i.e. 100 to 200mm) you will raise the ground level enough to ...

If you make raised beds, filled with commercial garden soil (tuin aarde), you can start right away. You can find instructions online on how to make raised beds, for instance videos like here.

It depends on how do you plant it. If you buy it in a pot, and you can plant without touching much the roots, it doesn't matter so much the period you plant it. But if you get with bare roots, fall/...
