I have a daisy plant which I bought 3 months back. It was blooming nicely for 2 months and slowly the blooming stopped and the plant is drying out. I assumed it was root rot and checked the roots. It looked clean. Also reduced the watering too but still it is the same. What could be the problem? The same is happening for my lavender too. It is drying out.

to NGA!
are these in pots or in the ground? Sounds like they both need more water. Can you give us more information and show photos?

Sorry. I thought I attached the photos. They are in a pot.

Is this your plant?

My experience when I grew it in California was that it bloomed heavily in spring/early summer and then took a break in the hottest months, reviving in fall, but I grew it in the ground. You can trim about a quarter off the top and see if it rebounds. That looks like very peaty soil which might be holding a lot of water in that plastic pot so be careful that it doesn't get soggy, but don't let it dry out.

As for your lavender, it likely will not bloom again this season, or if it does it will be a sparse bloom late summer or fall. You can also trim the top growth. if it's in the same kind of pot and soil as the daisy it might not do well. I recommended extremely well draining soil in a clay pot. Water thoroughly, somewhat infrequently but don't let it dry out completely or its roots stay soggy...to be repetitive, in my experience, the key to success with potted lavenders is the soil drainage.

Thank you for the detailed explanation. So Im going to buy some clay pots for the plants and also change the soil by adding more stones and gravel for better drainage.

Oops, no, rocks and gravel at the bottom aren't the solution and can make water retention worse. Buy a bag of cactus soil and mix in about 25% volume of perlite or pumice or chicken grit. Okay to mix in gravel, just don't layer it at the bottom. Pots of course should have drainage holes (I think you knew that).

Looking at your upcoming temperatures, you should be okay to transplant, but afterwards keep the plants in partial shade (during afternoons, or place in dappled sun under a tree) until they've established their roots and you can see new growth. No full all-day sun, plus keep them well watered during that time. You want to gently knock off the existing soil being careful not to damage the roots. B

Good luck with your plants!

You have been super helpful. Thank you. Will post update in few months.

You're welcome!
