After you buy

Keeping flower in this climate: nine practical answers

Updated 28 August 2026

Nothing on this page rests on a rule or a notice, because there is no rule about how you store something you already own. Every answer below is marked as practical caution: this is what we see coming back over the counter, described as experience rather than as law. It is also the part of the subject that visitors from cooler places consistently underestimate.

How long does flower stay worth having in this climate?

Practical caution — not a legal conclusion

Shorter than you expect, and the aroma goes first. In an air-conditioned room a well-cured jar holds its character for a couple of weeks; in a bag carried around in the afternoon heat, the top notes start flattening within days. Nothing dangerous has happened at that point — it has simply stopped being the thing you chose.

That is why we suggest buying for the days you are actually here rather than for the trip. It is not a sales position; it works the other way round, and we say it anyway because a flat jar on day nine is what people remember about the whole visit.

What are heat and humidity actually doing to it?

Practical caution — not a legal conclusion

Two separate things. Heat drives off the volatile compounds that make an aroma legible — that is why a jar left in a car or on a balcony reads as generically herbal afterwards, whatever it smelled like at the counter. This part is not reversible, and no amount of careful storage later brings it back.

Humidity works the other way: it puts moisture in. Damp material is where visible growth becomes a possibility, and that is a genuine reason to discard rather than a matter of taste. The two problems pull in opposite directions, which is why the answer is a stable room rather than any single trick.

What should I keep it in?

Practical caution — not a legal conclusion

Whatever it came in, if that was rigid and closes properly, kept out of the light. Glass with a tight lid is the ordinary answer everywhere and it is the ordinary answer here too. The point of the container is to hold a stable little atmosphere, which a thin plastic bag cannot do.

A bag has a second problem specific to travelling: it crushes. Material that has been squashed in a pocket for three days has lost its structure before it has lost anything else, and structure is a large part of what you were looking at when you chose it.

Should I put it in the hotel fridge?

Practical caution — not a legal conclusion

We would not. The problem is not cold, it is the trip in and out: every time a cold jar meets a room at thirty-something degrees, moisture condenses on what is inside it. Doing that twice a day for a week is a reliable way to end up with damp material.

A minibar is also the least stable appliance in the room, and in a good many of them the temperature is a suggestion rather than a setting. A cupboard away from the window achieves more with less drama.

Is the room safe a sensible place for it?

Practical caution — not a legal conclusion

As a place that is closed and dark, yes, and that is most of what storage requires. What a safe does not do is change anything about whose room it is or what the property's own rules say, and those two questions are answered on the page about where you may use it rather than here.

One practical note: safes in this climate are often built into a wardrobe against an outside wall, and the inside of one can be warmer than the room. Check it with your hand once before deciding it is the cool option.

Is it better to buy once for the whole trip?

Practical caution — not a legal conclusion

It usually is not, for two unrelated reasons. The first is on this page: what you buy on day one is not the same thing by day ten in this heat. The second is that whatever is left when you leave has to stay in Thailand, and that question is dealt with in full on the page about going home.

Buying twice for a two-week stay solves both at once. It also means the second jar is chosen by someone who now knows what they liked about the first, which is worth more than any description on a website.

Is there any harm in preparing it in advance?

Practical caution — not a legal conclusion

Ground material has far more surface exposed to the air, so everything described above happens to it several times faster. Prepared in the morning and left until evening in a warm room, it is noticeably flatter by the time it is used.

If you are going out and want to carry a small amount, prepare that amount rather than the jar. The rest keeps better whole, and there is no benefit to be had by doing the work early.

How do I tell whether it has gone too dry or too damp?

Practical caution — not a legal conclusion

Too dry crumbles at a touch and has almost no smell left; it is disappointing rather than a problem. Too damp is the one to take seriously: it feels cool and slightly springy, it may smell faintly of hay or of a cupboard, and it will not break cleanly.

Anything with visible fuzz, powder or discolouration on it goes in the bin. There is no rescue procedure, no airing it out for a day, and nobody at a counter will tell you otherwise. This is the single point on this page where the correct answer is to lose the material.

The jar makes the whole room smell. What can I do about it?

Practical caution — not a legal conclusion

Keep it closed and keep it in something rigid; most of what escapes into a room escapes while a container is open on a table, not through a closed lid. A second container around the first does more than any spray does.

The reason this matters is not tidiness. A room that smells is a conversation with housekeeping, and that conversation is governed by the property's own rules, which are covered on the page about where you may use it. Storage and use are different questions, and only the first one is answered here.
