Growing Sage Indoors

I love to use sage in cooking, it is so flavorful, and can be used in marinades, herb butters, sauces, to flavor stuffing, or crumb crusts.

Especially in the wintertime I find myself using in recipes, and so I like to make sure I have a healthy sage plant in my kitchen in time for the holidays.

The great thing about growing sage indoors is that you can have it available fresh at any time of the year!

Sage likes to be in a sunny spot, and so a sunny kitchen windowsill is the ideal place to keep it!

Growing Sage: Frequently Asked Questions

Is sage easy to grow from seed?

Yes! Sage is easy to grow from seed. It is relatively quick to grow (see section below), and doesn’t need much special care.
It is relatively drought-tolerant and so forgiving of a slightly unpredictable watering schedule.

How long does sage take to grow from seed?

It takes 2-3 weeks for sage to start to grow from seed. The seedling need to be allowed to grow to around a few inches tall before re-potting and allowed grow into a full-sized plant.
It takes around 12-16 weeks to become a fully established plant. So start it growing in around early September if you want it ready for all the holiday recipes!

Should I soak sage seeds before planting?

It is not necessary to soak sage seed before planting. In fact, unless you are very careful you can over soak them, so I would say in general not to bother.
Sage seeds will germinate more quickly if you have soaked them prior to planting, so if you are wanting to grow a sage plant from seed in a hurry then soaking the seeds for up to 24 hours may save you a few days in germinating time.
Just please be careful not to over soak them!

How do you plant sage seeds?

To plant the sage seeds:
1. Fill seedling pot to around three-quarters full with potting mix.
2. Place seeds on top of the soil – you can put more than one seed in each seedling pot, but be sure to space them out around 1/2 inch between seeds.
3. Use more potting mix to cover the seeds and fill the seedling pot almost to the top.
4. Press down gently so the soil feels secure
5. Place seedling pot on a saucer, and add water

How often do you water sage seeds?

Once the sage seeds have been planted, you need to leave them in a well lit place and water as needed until the seedlings appear.
They should only need to be watered once or twice per week, unless you live in a very hot climate.
Check the soil once per day and if it feels dry and crumby, pour a small amount of clean water over it. The soil should be damp, but not soaked. Sage prefers to be on the dry side, so be sure not to over water it.

How long will my sage take to grow?

Once you have planted the sage seeds, you need to leave them in a well lit place and water frequently until the seedlings appear. This can take from 7-21 days.
Once the seedlings have become well established (around 6-8 weeks after planting) re-pot them into a small plant pot with good quality potting mix.
The sage should be ready to harvest around 6 weeks later (approximately 12-16 weeks after planting the seeds).
