Weekly Stem Reconciliation Calculator

Have you overcommitted this week? Put in what you expect to cut of each crop, and what you've already promised across weddings, CSA, market and wholesale. You get the shortfall to buy in and the surplus to sell — crop by crop, before Monday.

This week, crop by crop

Nothing — every promise is covered.

Spare to push

Nothing spare this week.

One week here, every week there

This is one week. Your season is twenty of them.

This page reconciles the week in front of you. Stemwise keeps the same sum running all season: it projects what each bed will cut, holds every wedding recipe, CSA share and market order against it, and shows you the collision in February — while you can still plant your way out of it.

What "reconciling" a week actually means

Every other flower-farm calculator answers a supply question: how many stems will this plant give me, how many plants do I need, what should a share cost. Reconciliation is the only one that puts supply and demand on the same page. It asks one question: for each crop, is what I'll cut this week bigger or smaller than what I've already promised?

The arithmetic is deliberately plain — a subtraction you could do on the back of a seed packet:

StepWhat you do
1. SupplyStems you expect to cut of that crop, this week
2. DemandAdd up every promise: weddings + CSA + market + wholesale
3. BalanceSupply − demand
4. ActNegative → buy in or renegotiate. Positive → sell it before it blows.

Nothing here is estimated on your behalf. The tool supplies no yields, no prices and no assumptions — you supply both sides and it does the subtraction, crop by crop, so a shortfall in dahlias can't be hidden by a glut of zinnias in the same total.

Why the total is the number that lies

Most growers do carry this sum in their head, but they carry it as one number: "I think I've got enough." That total is almost always fine, and it is almost always wrong. A week can be 400 stems up overall and still be 60 dahlias short for the Saturday wedding — and dahlias are the stems the bride is paying for. Reconciliation is only useful crop by crop. That is why this page makes you list them separately, and why the summary shows shortfall and surplus as two independent numbers instead of netting them into one.

Where your "will cut" number comes from

Reconciliation is only as honest as the supply side. If you don't have a harvest record to read off, estimate it from plant counts and per-plant yields — our cut-flower yield per plant table gives stems-per-plant-per-season for 30+ crops, and the planting calculator runs the same numbers in the other direction. Plan to the low end of any yield range. A shortfall you predicted is a phone call; a shortfall you discover on harvest morning is a refund.

What to do with each answer

Do it every Sunday

This is a five-minute habit, not a project. Run it once a week, before you confirm anything new — that's the whole discipline, and it's written out longhand here. The point of doing it on Sunday is that every option is still open. By Thursday, the only option left is apologising.

Weekly stem reconciliation FAQ

What is stem reconciliation?

Stem reconciliation is comparing the stems you expect to cut in a given week against the stems you have already promised to customers — weddings, CSA shares, market, wholesale — one crop at a time, so you know your shortfall and your surplus before the week starts.

How do I know if I have overcommitted my flowers?

For each crop, add up every promise you have made for that week and subtract it from what you expect to cut. Any crop with a negative balance is overcommitted. Do it per crop, never as one total — a farm can be well ahead overall and still be short of the one flower a wedding was sold on.

What should I do if I am short of stems this week?

Buy the shortfall in from a wholesaler or a neighbouring farm, substitute a crop you are long on after checking with the client, or move the delivery. Every one of those is straightforward a week out and painful two days out, which is the whole reason to run the numbers on Sunday.

How much buffer should I leave when I sell my flowers?

Most growers plan to the low end of their yield range and keep 10 to 15 percent headroom on any crop carrying a wedding, because weather, pests and a hot week that opens everything early all cut supply and none of them give notice.

Is this calculator free?

Yes. It is free, needs no signup, and runs entirely in your browser — nothing you type is sent anywhere. Your numbers are saved on your own device so the week is still there when you come back.
